v01. Known Issues
OpenMP: some compiler versions (intel and somegfortran some gfortran versions) are known to produce SEGV if OpenMP is enabled in optimized compilation. This will be fixed in the next a future release. In the meantime, we recommend that if you find this occurs, remove OpenMP options from the compilation and only use MPI.
Intel compiler on SandyBridge CPUs: . We recommend using -O1 and no higher for the intel compiler. At high optimization levels (-O2), the intel compiler causes SEGV when executing on SandyBridge processors. We recommend using -O1 and not enabling AVXon processors that support the SSE4.1 and AVX instruction sets (Harpertown & Sandybridge CPUs). The FCM configuration files for the Intel compiler use a default of -O1 for the optimized build.
Bit reproducibility: The Intel MKL library is known to cause non-reproducible results. If this is an issue a code wrapper can be applied.
