Summary0000779: INTEL compiler issue on AMD system
DescriptionDear Support Team,

I installed OF 2.2.x on an AMD cluster using INTEL compiler suite 2013. However the binaries are not working after compilation. The reason is the AMD specific unsupported instruction set SSE4a, which is unsupport by INTEL compilers. So, instead of using the hard coded flag -xSSE3 in "wmake/rules/linux64Icc/c++Opt" I suggest to use -xHost. Thus, the INTEL compiler automatically selects the best optimization level on the system.

Best regards
