Good to find you! I want to buy a new system for HPC research.
I already use a 4x(AMD Opteron(tm) Processor 6174) system running Linux. I use it for running computational intensive simulations in a shared-memory (OpenMP) manner.
I need to buy a new dedicated machine and I was thinking about a 4x12-core or 4*16-core based on the new 6200 opteron cpus. But, I see a big argue on the internet about the FPU of this platform. (look here
in the comments)
I quote one of the most disturbing: "For non-FPU-heavy workloads, you can get away with that. For pretty much the entire scientific/math/engineering (SME) community; it's an 8-core processor or a highly crippled 16-core processor." by alpha754293
I do mostly FP calculations since I'm into engineering. I program in Fortran-2003 and I make extensive use of BLAS and LAPACK libraries in Double Precision. Moving to this platform will cripple the cores? In general, how do the 6100 series compare towards the 6200 series in FP computation?
Thanks in advance,
