Happy New Year, Gus! Yes, I'm using affinity. This is my openmpi-mca-params.conf file:
--- # Use RSH instead SSH pls_rsh_agent=rsh # Turning on processor affinity mpi_paffinity_alone=1 # Include using eth1. btl_tcp_if_include=eth1 # Exclude using lo and eth0. btl_tcp_if_exclude=lo,eth0 --- I rebuild openmpi-1.3.3 from tar and find something interesting. If i build with this options: CC=icc CXX=icpc F77=ifort FC=ifort ./configure --prefix=/opt/testing/default/openmpi-1.3.3/ --disable-ipv6 All work's fine!!! But if I use: CC=icc CFLAGS=" -O3" CXX=icpc CXXFLAGS=" -O3" F77=ifort FFLAGS=" -O3" FC=ifort FCFLAGS=" -O3" ./configure --prefix=/opt/testing/tuning/openmpi-1.3.3/ --enable-debug --enable-mpi-threads --disable-ipv6 Then I get errors. What you think? Now I'm starting to investigate, what options cause OpenMPI broken.
