AMD cpu's here at AO:
rserv1: 6172 (opteron 6100 family, K10
microarchitecture) 4x12cores=48 cores. does not support
avx
each processor modules has 2cores and 1 fpu unit. The fpu
has 2 128bits sets of registers so it can do 2 128bit
operations simultaneously (lettting each core run). When the
say that they support "avx" they really mean the 128 bit avx
instructions that emulate sse4. For true 256 bit operation 1
core has to use all of the fpunit.
