Hello: I'm having some issues with Open MPI 1.4.1 and Pathscale compiler (version 3.2). Open MPI builds successfully with the following configure arguments:
./configure --with-openib=/usr --with-openib-libdir=/usr/lib64 --with-sge --enable-static CC=pathcc CXX=pathCC F77=pathf90 F90=pathf90 FC=pathf90 (we have OpenFabrics 1.2 Infiniband drivers, by the way) However, applications hang on MPI_Init (or maybe MPI_Comm_rank or MPI_Comm_size, a basic hello-world anyway doesn't print 'Hello World from node...'). I tried running them with and without SGE. Same result. This hello-world works flawlessly when I build Open MPI with gcc: ./configure --with-openib=/usr --with-openib-libdir=/usr/lib64 --with-sge --enable-static This successful execution runs in one machine only, so it shouldn't use Infiniband, and it also works when several nodes are used. I was able to build previous versions of Open MPI with Pathscale (1.2.6 and 1.3.2, particularly). I tried building version 1.4.1 both with Pathscale 3.2 and Pathscale 3.1. No difference. Any ideas?
