Port likwid-bench to Intel Xeon Phi (KNC) #78

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
KNC is X86 but not binary compatible with x86-64.

likwid-bench must be ported to KNC ABI

Hi,

Could you tell me the specific steps to port likwid-bench to KNC?

I have also encountered the problem:

Necessary steps are:

1. Check if the ABI needs to be adopted for the Code generator (I hope this is 
not necessary).
2. Adopt build system to assemble files for MIC
3. Reimplement base benchmark set using KNC Vector instructions (as 
replacements for present benchmarks)

I hope I  find time for this soon. If you have success please keep me informed.
