I've compiled the linpack benchmark using openMPI 1.8.5 libraries and include files on CentOS 6.4.
I've tested the binary on the one Intel node (some sort of 4-core Xeon) and it runs, but when I try to run it on any of the old Sunfire opteron compute nodes it appears to hang (although top indicates CPU and memory usage) and eventually terminates by itself. I'm also getting the following openMPI error messages/warnings: mpirun -np 16 --report-bindings --hostfile hostfile --prefix /hpc/apps/mpi/openmpi/1.8.5-dev --mca btl_tcp_if_include eth0 xhpl [cscld1-0-6:24370] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-3:24734] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-7:25152] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-4:18079] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-8:21443] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-2:19704] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-5:13481] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1-0-0:21884] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 [cscld1:24240] 7 more processes have sent help message help-opal-shmem-mmap.txt / target full Note these errors also occur when I try to run the linpack benchmark on a single node as well. Does anyone know what's going on here? Google came up w/nothing and I have no idea what a BTL coordinating structure is. -Bill L.
