[OMPI users] Old version openmpi 1.2 support infiniband?

Hi everyone, Recently I need to compile High-Performance Linpack code with openmpi 1.2 version (a little bit old). When I finish compilation, and try to run, I get the following errors: [test:32058] *** Process received signal *** [test:32058] Signal: Segmentation fault (11) [test:32058] Signal co
