Here's an example.  Consider the following little test program:

#include <stdlib.h>
#include <string.h>

main()
{
    size_t size = 1000000;
    int iters = 1000;

    unsigned char *buf = (unsigned char *)malloc (size);

    register unsigned char sum = 0;

    for (register int i = 0; i < iters; i++)
    {
    for (register int j = 0; j < size; j++)
        sum += buf[j];
    }

    return sum;
}

Compiled as follows:

g++ -o simple simple.cpp

(So - no optimization.)

I would expect this to do ony reads, and no (or very few) writes to main memory.  In fact, if I look at events 0x6C (reads) and 0x6D (writes), it seems to do about as many reads as writes, if I'm interpreting the results correctly.  Hmmm ... Maybe "sum" isn't being put in a register, in spite of the "register" keyword.  That's the only theory I have.  But I'm not sure that I believe that.

The actual results I got from one run were 7566 for reads, 31897 for writes and 3128 for DRAM accesses - all with a sample period of 10,000.  And ... hmmm ... maybe that sample period should be 500,000.  But, still ...

Another question: Why is event 0xE0 (DRAM accesses) not equal to the sum of event 0x6C (reads) and 0x6D (writes)?

What I'm ultimately trying to determine is if a real program (not the above test) is bumping up against memory bandwidth limits, but I'm not sure which event or events I should look at.  BTW - I have looked at Paul Drongowski's "Basic Performance Measurements ..." document, which is certainly very helpful, but still leaves me with some questions.  (Maybe I'm just thick!)

I am interested in installing perfmon2 on my AMD 64 box running RHEL5.3 server. I tried installing this using 'yum', but it seems the library only works for itanium 64 archs and not for amd64.

I also tried to get the latest patch from sourceforge but it gives errors while patching the kernel file.

Please suggest me if someone is able to achive this task.

Thanks!

I manually installed the codeanalyst package from openSUSE 11.1 Contrib (http://download.opensuse.org/repositories/openSUSE:/Factory:/Contrib/openSUSE_11.1/x86_64/) and ran it as root user. I can go through the tutorial until the step where i would actually run the program. There i receive the GUI error.

Error starting profile: Failed to setup OProfile.

When looking at /var/log/messages, I get the following line:

Oct 20 14:50:21 sedici sudo:     root : TTY=unknown ; PWD=/opt/CodeAnalyst/bin ; USER=root ; COMMAND=list

/opt/CodeAnalyst is where bin, lib64, sbin and share are located. I wonder what this 'list' command is all about. Because there is absolutely no such command in my path. I also think that the kernel oprofile module has been successfully loaded, since the 'rccodeanalyst start' script runs with no errors and i get the following, when doing 'ls /dev/oprofile':

0  2  backtrace_depth  buffer_size       cpu_buffer_size  dump    pointer_size
1  3  buffer           buffer_watershed  cpu_type         enable  stats

Thanks in advance!

Paul's artcile introduces two methods for L2 cache. One is direct method and the other is indirect method.

Direct method:
L2 request rate = (L2_requests + L2_fill_write) / Ret_instructions
L2 miss ratio = L2_misses / (L2_requests + L2_fill_write)

Indirect method:
IC_misses = IC_refills_L2 + IC_refills_sys
DC_misses = DC_refills_L2 + DC_refills_sys
L2_requests = IC_misses + DC_misses + L2_requests_TLB
L2 request rate = L2_requests / Ret_instructions
L2_misses = IC_refills_sys + DC_refills_sys + L2_misses_TLB
L2 miss ratio = L2_misses / L2_requests

I have some questions about L2 Cache measurement.

1. How to compute L2_request_TLB in the indirect method?
My understanding is L2_request_TLB is equal to the sum of L1_ITLB_MISS_AND_L2_ITLB_MISS and L1_DTLB_AND_L2_DTLB_MISS. Event REQUESTS_TO_L2 has a mask bit (0x4) for TLB. I measured mcf and vortex in SPEC2000.

opcontrol --event=REQUESTS_TO_L2:50003:0x4--event=L1_ITLB_MISS_AND_L2_ITLB_MISS:50003  --event=L1_DTLB_AND_L2_DTLB_MISS:50003 --image=mcf.exe,vortex.exe

L1_DTLB_AND_L2_DTLB_MISS|REQUESTS_TO_L2:0x4|L1_ITLB_MISS_AND_L2_ITLB_MISS:50003|
  samples|      %|  samples|      %|  samples|      %|
-------------------------------------------------------------------------
     1377 100.000      1664 100.000      0 100.000  mcf.exe
     1192 100.000        10 100.000      1816 100.000 vortex.exe

The is a big discrepancy between REQUESTS_TO_L2:0x4 and (L1_ITLB_MISS_AND_L2_ITLB_MISS + L1_DTLB_AND_L2_DTLB_MISS). Which is appropriate? 

2. How to compute L2_request?

Direct method: L2_requests + L2_fill_write
Indirect method: IC_misses(IC_refills_L2 + IC_refills_sys) + DC_misses(DC_refills_L2 + DC_refills_sys) + L2_requests_TLB

1) Direct method
opcontrol --event=L2_CACHE_FILL_WRITEBACK:50003 --event=REQUESTS_TO_L2:50003:0x7 --image=mcf.exe, vortex.exe

L2_CACHE_FILL_WRITEBACK|REQUESTS_TO_L2:0x7|
  samples|      %|  samples|      %|
------------------------------------
    16402 100.000     15920 100.000 mcf.exe
    11610 100.000     13761 100.000 vortex.exe

L2_request_mcf_direct = 16402 + 15920 = 32322
L2_request_vortex_direct = 11610 + 13761 = 25371

2) Indirect method
opcontrol --event=DATA_CACHE_REFILLS_FROM_L2_OR_SYSTEM:50003--event=INSTRUCTION_CACHE_REFILLS_FROM_L2:50003 --event=INSTRUCTION_CACHE_REFILLS_FROM_SYSTEM:50003--event=REQUESTS_TO_L2:50003:0x4 --image=mcf.exe,vortex.exe

INSTRUCTION_CACHE_REFILLS_FROM_L2|INSTRUCTION_CACHE_REFILLS_FROM_SYSTEM|REQUESTS_TO_L2:0x4|DATA_CACHE_REFILLS_FROM_L2_OR_SYSTEM |
  samples|      %|  samples|      %|  samples|      %|  samples|      %|
------------------------------------------------------------------------
     2251 100.000        15 100.000      2160 100.000      7587 100.000 vortex.exe
     1 100.000           0 100.000      1660 100.000     10491 100.000 mcf.exe

L2_request_mcf_indirect = 2251 + 15 + 2160 + 7587 = 12013
L2_request_vortex_indirect = 1 + 1660 + 10491 = 12152

There is a VERY BIG discrepancy between L2_request computed with direct and indirect methods. Why?

3. Are the following statements right?

1) INSTRUCTION_CACHE_REFILLS_FROM_SYSTEM is equal to L2_CACHE_MISS:0x1.
2) DATA_CACHE_REFILLS_FROM_SYSTEM is equal to L2_CACHE_MISS:0x2.

Any suggestion is welcome! Appropriate measurement parameters are very necessary and important. We should have a unified version

Help | System Information included at bottom.

Here is what I am doing:

- Start | CodeAnalyst.exe

- File | new | project name = classic | OK

- On the "session settings dialog":

1) Changed to "time-based profile"

2) Launch= "C:\Program Files\AMD\CodeAnalyst\SampleCode\classic\Release\classic.exe"

3) Enable "stop data collection when the app exits" and "profile the duration of the app execution"

- Click OK

- Click Green "start profiling" icon.

- Classic.exe runs, finishes in about 10-15 seconds.

- CodeAnalyst loads SystemData/SystemGraph/Processes tabs.

- When I doubleclick on "classic.exe" from the Module name list on the System Data tab, there is a few second pause, and then I get a dialog title "Code Analyst Error". The error is "The specified module (\\Device\HarddiskDmVolumes\PhysicalDmVolumes\BlockVolume1\Program Files\AMD\CodeAnalyst\SampleCode\classic\Release\classic.exe) cannot be found. No module information can be shown.

I saw another post about how this is a problem if the drive is encrypted or removable, but that is not the case here -- C: is not encrypted, nor is it removable. I tried moving the contents of classic to c:\temp\classic and running it from there, but same result - get a very similar error message.

Can you help?

thanks!

-Frank.

There are hundreds (maybe thousands) of objects in the code I am analyzing, so I would like to automate the profiling process. For this purpose, I wrote a script that parses the CSV files exported by the CodeAnalyst GUI to derive the information I am looking for. However this script is useless unless I can find a way to export CodeAnalyst data that does not involve clicking on object names one by one to export them.

I can run the profiler from the command line (using opcontrol) but I could not find a way to generate CSV from the command line, I eventually have to import it into the GUI. The generated data, which is dumped under /var/lib/oprofile, is not human readable.

My question is, is there a way to generate a CSV for each different object from the command line? It would be very useful if the GUI provided a way to export data for *all* objects in separate CSV's, instead of clicking on them one by one to export, such as "export all" (?)

Please tell me if my question is not clear. I will try to clarify with an example if needed. Thank you very much in advance!

I'm a total beginner with CodeAnalyst and tried to create in Eclipse CDT on Windows XP a HelloWorld application by using the Mingw compiler and the Eclipse C++ HelloWorld template.

I compiled a "debug" executable and run CodeAnalyst on it.

The compiler settings are "g3" for maximum symbol information and optimization was switched of.

There wre results produced but when doubleclicking on this process I get a new window with adresses and behind the message "NO SYMBOL".

Doubleclicking on such a line just opens asembler code. How can I get the code displayed in CodeAnalyst like shown in the tutorials? What is my mistake?

Thank you for your help

Is there a way to obtain a merged symbol view for multiple modules?  (That is, if I have both A.dll and B.dll contributing time, I want to view a list of symbols in either module, sorted by number of samples, instead of only being able to view the symbols in A.dll /or/ the symbols in B.dll.)

I am running Code Analyst through Visual Studio 2008, I am trying to see the symbols from d3d9.dll which i've downloaded / cached locally using MS's PDBs, but they don't seem to be being picked up by Code Analyst.  Is there any way to specify extra PDB files?

Thanks for your help!

All the best,
Ash 

The filename in the error message is the path to the CodeAnalyst install directory plus an assortment of seemingly random chinese characters.

FunctionName$omp1FunctionName

and

FunctionName.

So now wat wud be the total time taken or rather the total samples for that function? Is it the sum of the samples for both instances or something els? Plz enlighten me.

Thanks in Advance.

I am trying to select performance counters to measure CACHE, DISK and Memory utilization in AMD Opteron systems.

Can I expect to get to get usage using following performance event monitoring:

1. Cache:  Data Cache Accesses and Instruction Cache Acceses

2. Memory: Dram Accesses (with unit mask 0x01 for Page hit)

3. Disk: There are two components: dma and non dma

a. Dram Accesses with unit mask 0x02 for Page Miss

b. hypertransport link0 with unit mask 0x02 for dma'ed data

If anybody has done any of these measurement, please comment if there is some gap in my understanding.

I tried to run a sample copy script (copying a large image 1 Gb in loop) and analyzing the above events, I was not able to conclude much from it.

Thanks for your suggestions!

Regards,

Ata

The event CPU_CLK_UNHALTED means "CPU Clocks Not Halted". Does Oprofile count the latency time caused by cache misses or I/O?  These events can cause CPU halt.  If not, the CPU_CLK_UNHALTED sampling result makes little sense and cannot represent program performance.

But the document "Basic Performance Measurements for AMD Athlon™ 64,AMD Opteron™ and AMD Phenom™ Processors"  says "IPC = Ret_instructions / CPU_clocks", which means CPU_CLK_UNHALTED counts cache misses and I/O waiting time. Is it right?

BTW, when I changed event count to 1,0001 the sampling result is 752,647. And changed to 10,0001, the result is 167,612. Why does not the sampling result scale with the event count?

I'm confused...

Any suggestion is welcome.

i have some trouble with the CodeAnalyst 2.94.718.0 on Windows XP with latest SP and a Intel Centrino Platform.

First, I selected the default time based sampling configuration and started my app to be profiled. It runs for 20 s, then says "No session data" "The selected session does not contain any data".

I, then, tried to profile the included classic.exe and the same thing happens no matter if I use the precompiled classic.exe or the one compiled by Visual C++ 2005 express.

Did I miss something? Shouldn't that work right out of the box?

Best regards

Rainer

I installed the most recent CodeAnalyst on Windows 7 64 RC.  Lately I'm getting regular bluescreens in ampcore.sys, but only when the machine has been idling for some time (eg. when running overnight).  When I get back it's usually bluescreened:

"The bugcheck was: 0x0000001e (0xffffffffc0000096, 0xfffff8800b4ef838, 0x0000000000000000, 0x0000000000000000)."

Is anybody else seeing this?

It happens even if I haven't used CodeAnalyst at all during the session.  It might be a bug related to automatic standby/hibernation (although they don't actually seem to work for me on Win7, but manual ones do without this problem)... or maybe it's just a leak that breaks over time?

I've used Code analyst but the results are not clear...
It shows four threads running on a single core.. Its pretty confusing

Thanks

The device driver failed to start profiling, please try again.

A trial version of Compuware BoundsChecker also hangs when trying to start program, so I think it may be something that breaks all advanced profilers (VerySleepy still works, though).

Can anyone advice me what to do? I think it may be a problem with anti-virus software (though turning protection off on NOD32 did not help) or with some system service, but I'm not sure what to try.

I have been trying to compile CodeAnalyst (2.8.54) on an Ubuntu 8.10 server.  I have worked through many issues but i am stuck on this one.  Can any one offer any advice?

Here is the brute force way of doing it:

if( splitAxis == 0 )
{
   if( v1.x < splitPosition ) { ... }
   if( v2.x < splitPosition ) { ... }
   if( v3.x < splitPosition ) { ... }
}else if( splitAxis == 1 )
{
   if( v1.y < splitPosition ) { ... }
   if( v2.y < splitPosition ) { ... }
   if( v3.y < splitPosition ) { ... }
}else if( splitAxis == 2 )
{
   if( v1.z < splitPosition ) { ... }
   if( v2.z < splitPosition ) { ... }
   if( v3.z < splitPosition ) { ... }
}

I assume there could be much divergency in the above code.

if the float4 could be access this way:
  float4 data; data[0] = 1.0f; which is same with:
  float4 data; data.x = 1.0f;

The above code could be improved like this
if( v1[splitAxis] < splitPosition ) { ... }
if( v2[splitAxis] < splitPosition ) { ... }
if( v3[splitAxis] < splitPosition ) { ... }

So i simulated the process by an alternative way.

shared float4 lds[256];

lds[ 4 * instanceInGroup().x + 0 ] = float4( v1.x , v2.x , v3.x , 1.0f );
lds[ 4 * instanceInGroup().x + 1 ] = float4( v1.y , v2.y , v3.y , 1.0f );
lds[ 4 * instanceInGroup().x + 2 ] = float4( v1.z , v2.z , v3.z , 1.0f );

if( lds[ 4 * instanceInGroup().x + splitAxis ].x < splitPosition ) { ... }
if( lds[ 4 * instanceInGroup().x + splitAxis ].y < splitPosition ) { ... }
if( lds[ 4 * instanceInGroup().x + splitAxis ].z < splitPosition ) { ... }

In the current code , i thought there could be much more improvement, but when the code is compile on kernel analyzer.]
The performance is worse than the old one... I don't get it. And the bottle neck of the current code is ALU Ops.
But actualy there are three times ALP ops in the old code than the current one. Why there is no performance??

I'm trying CodeAnalyst 2.94.718.0. If run as stand-alone (started from the icon) then everything is OK. But when trying to lunch anything from the VS 2008 I can't see any letters in the dialogs. Even, looking into "Tools->Options" and then finding "AMD CodeAnalyst ..." all dialogs there are also unreadable...

 Please, advise something...

The Time-based profling shows the percentage distribution, but how can i get the execution time in ms?

Thanks for you help.

Mike

I am writing my own drivers to collect performance events.

I have succeeded in programming the IBS registers and catching the interrupts and saving the information.

I want to do similar things with the PMCs.  But what I can't find out how to do is find the instruction address where the running thread was interrupted.

I can get the HANDLE for the interrupted thread.  But I have found no documented kernel support functions that will give me, say, the context record for the running thread.

Could somebody tell me how the CA's driver does this?

Or does somebody know in general how it can be done?

(Looking at OProfile for linux would not be any help on Windows, unless it actually uses hardware registers only.  I'll look it up, and if I find anything useful for Windows, I'll post that information here.)

The Add-in 'CAToolBar.connect' failed to load or caused an exception. Would you like to remove this Add-in?

Short description of the Program and the used analyses:

The Application I am trying to analyze uses multiple processes and communicates with an own implementation of an event system. How to react on every event is based on the data passed with these events.

When I want to analyze the application, I use a batch file to start the different executables. I have CSS enabled with the largest possible 'callstack unwind level' from within the GUI (72).

Since I am only interested in finding the bottlenecks within my application, I use the Time based profile. If I look at the data after running the profile the results indicate that my bottleneck lies within stl operations, mostly within the creation and comparison of std::string and std::vector.

<quote>std::basic_string<wchar_t, std:.char_traits<whcar_t>,std::allocator<wchar_t> >::assign</quote>

If I look at the CSS stack of the application, I can locate the stl calls I see within the profile data, but the ancestors only lead to other stl operations.

Question:

I have searched the documentation and the forum for the possibility to backtrace the function call further with no result.

Which brings up two questions:

1. is it possible to configure the profiler to only list hits within a define binary/executable(s)?

2. how do I find the parent of the parent of a operation, I.e. from the STL?

I hope I have described the problem accurately enough.

Best regards,

Kai Henkel

Using VS 2005 with an Intel Core Quad, so I can only use Time-based profiling (right?).

I'm developing processes for linux machines (Suse) that do not have GUI capabilities. I was wondering if it's possible to profile the processes on Linux but use the Windows GUI to display the results.

M

Some of the enhancements added are:

• Multiple simultaneous symbol servers.
• Process filters: You can limit the reported data to certain processes.
• An API: No longer are you limited to interacting with AMD CodeAnalyst through our command line applications or our GUI, you can now programmatically control profiling and you can fold, spindle, and mutilate the data before displaying it.
• Notes: You can add a customized note to each profile session. This feature should help you remember essential details about a session and reduce the length of session names.
• Call stack data for a running process: You can now capture call stack information about a process using the command line tool without launching the process from CodeAnalyst.

You can learn a little more about the new version from Frank's blog post.  Be sure to download it and check it out for yourselves and let us know what you think! 

I'm trying out CodeAnalyst on Redhat Enterprise Linux WS release 4 on a 4 CPU Opteron (Each CPU is a Dual-Core AMD Opetorn processor 2218). I've installed (or so I think) everything correctly, but when I try running Codeanalyst on an application I get the following error

"Oprofile daemon failed to start

Reason: Cannot open /dev/oprofile/buffer_size.

Please check if:

1. The file exists

2. User in in "amdca" group".

From what I can see 

- Oprofile sampling driver is loaded (from "codeanalyst_init status")

- The file /dev/oprofile/buffer_size exists and is readable

- I am in group amdca

I've restarted codeanalyst, but get the same error.

What else do I need to check/fix?

Regards

Hari

is codeanalyst only planned for redhat and *suse plattforms ? Or is there a thought about making it linux-available? i tried CodeAnalyst-gui-2.8.38.tar.bz2 and CodeAnalyst-Linux-2.8.27.tar.gz on debian lenny 64bit but both compilations failed.

Is there anywhere a howto to compile CA, or a nearer explanation what versions of which tools,libs etc. are used, and why does the CAinstaller.sh script does not detect lib,header incompatibilities ?

thanks

i try to build ca but the first thing is, that it cannot find QT_DIR while running configure in main directory. The return is: Warning: a working Qt not found; no GUI will be built. This output comes from the src/oprofile/configuration file, the last statement, but i use this line to configure oprofile

./configure --with-qt-dir=/usr/lib64/q3 --with-qt-includes=/usr/include/qt3 --with-qt-libraries=/usr/lib64/qt3

when i then try to build it without gui support, then these errors show up

what do i wrong? thanks for help

flo

I tried different computers, different codeanalyst versions, different build options, different compilers (vc 7 an 9) ale no effect.

I need help with this because codeanalyst is useless for me with out that data.

I am having trouble with CodeAnalyst:

CodeAnalyst Warning

Oprofile collected no samples
Suggestion:
-Check the profiling duration
-Check number of counts for events
-Check "start delay period" and "start with the profiling paused" options

I am running Ubuntu on VmWare. Any ideas?

Thanks, Levent

i downloaded CodeAnalyst-gui-2.8.38.tar.bz2 and want to build it on debian lenny, but when i run configure it returns:

checking Oprofile /home/username/programs/codeanalyst/CodeAnalyst-gui-2.8.38/src/oprofile///config.h... no
configure: error: Please configure Oprofile in

i checked the INSTALLATION file and there is noted goto src/oprofile, but in the tar.bz2 is no directory named like this.

i run 2.6.29 kernel with oprofile activated.

what can i do to build codeanalyst ?

thanks for help

flo

Has anyone got a good recipe for setting this up?
