Hi, yesterday I installed openmpi-1.7a1r27358 and it has an improved error message compared to openmpi-1.6.2, but doesn't show process bindings and has some other problems as well.
"sunpc0" and "linpc0" are equipped with two dual-core processors running Solaris 10 x86_64 and Linux x86_64 resp. "tyr" is a dual-processor machine running Solaris 10 Sparc. tyr fd1026 105 mpiexec -np 2 -host sunpc0 -report-bindings \ -map-by core -bind-to-core date Sun Sep 23 11:46:36 CEST 2012 Sun Sep 23 11:46:36 CEST 2012 tyr fd1026 106 mpicc -showme cc -I/usr/local/openmpi-1.7_64_cc/include -mt -m64 -L/usr/local/openmpi-1.7_64_cc/lib64 -lmpi -lpicl -lm -lkstat -llgrp -lsocket -lnsl -lrt -lm openmpi-1.6.2 shows process bindings. tyr fd1026 103 mpiexec -np 2 -host sunpc0 -report-bindings \ -bycore -bind-to-core date Sun Sep 23 12:09:06 CEST 2012 [sunpc0:13197] MCW rank 0 bound to socket 0[core 0]: [B .][. .] [sunpc0:13197] MCW rank 1 bound to socket 0[core 1]: [.
