x86_64, yes, but, gcc + ifort. I can test with gcc+gfortran if that’s helpful.
No, no multithreading, at least not intentionally. I can run with OMP_NUM_THREADS explicitly 1 if you’d like to exclude that as a possibility. opal_config.h is attached, from ./opal/include/opal_config.h in the build directory.
