Now, when we use Intel CPUs, compiler flags for ifort are-132 -w95 -cm -align all -heap-arrays 256 -c -O3 -mp1 -axOW -freefrom what I understand, both -mp1 and -axOW flags are chip-specific. What can I use on Opteron? From what I understand -mp1 is designated to n...

Solved: Hi, Where can I get the documentation of the optimization flags and explanation for ifort and mpiifort 15.0.1. Thx.
alalazo deleted the alalazo:features/intel_optimization_flags branch Oct 22, 2019 Contributor glennpj commented Oct 22, 2019 I am pretty sure that this will interfere with the ability to use the Intel compiler with the -ax option. From the icc man page: If you specify both the -ax an...

When the -O3 or -O2(default) compiler flags (more aggressive compiler optimization flags) used for the ifort, one of the scipy tests may fail and it is a known corner case, to avoid this, as a workaround you can use -O1. Building with GNU Compiler chain: ...

I'm using the Intel offline compiler and the LLVM-based optimizer with Intel specific optimizations (oclopt). For the optimizer I have used regular O optimization levels (O1, O2, O3) which included many optimization in two passes. As there are plenty of individual optimizations available, I'...
