[yt-users] using Intel compilers

[Mark Kremenetsky]

peter,
  I agree that gnu compiled library will work quite nicely with a code 
compiled with Intel compiler. It is exactly what i have done for x86_64 
processors. But I am trying to make a port for new Intel Phi processor ( 
also called MIC)  which has a different set of instructions so  only 
code compiled with a special version of Intel compiler will generate 
such executable.
As a first phase i am trying to build ENZO ( including all tools) for  
x86_64 using only Intel compilers. If I  succeed with such build then it 
will be straightforward to move on with a special version of compiler.
I can set my question in a different way: if anybody was able to port yt 
environment on MIC processors ?
Thanks,
Mark
