Release: 121203. Known Issues
OpenMP: some compiler versions (intel and somegfortran versions) are known to produce SEGV if OpenMP is enabled in optimized compilation. This will be fixed in the next 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: At high optimization levels (-O2), the intel compiler causes SEGV when executing on SandyBridge processors. We recommend using -O1 and not enabling AVX.
Bit reproducibility: The Intel MKL library is known to cause non-reproducible results. If this is an issue a code wrapper can be applied.
