[OMPI users] libnuma with openmpi
Hi Team, I am trying to test an application with libnuma on openmpi 1.8.1. The code compiles, but at runtime am getting libnuma warning and it dies with segmentation fault. libnuma: Warning: cpu argument 8 is out of range -- mpirun noticed that process rank 1 with PID 62744 on node test-1 exited on signal 11 (Segmentation fault). -- System information: RHEL 6.6 GCC 4.4.7 open-mpi 1.8.1 This code works perfectly on MVAPICH2. How can I enable libnuma on openmpi? Any help is greatly appreciated. Regards, Chaitra
Re: [OMPI users] libnuma with openmpi
Can you provide a bit more detail? Is the seg fault in your code or in Open MPI? Note that Open MPI uses hwloc (which likely uses libnuma) internally, too. > On May 11, 2015, at 2:17 AM, Chaitra Kumar wrote: > > Hi Team, > > I am trying to test an application with libnuma on openmpi 1.8.1.

[OMPI users] failure of 1.8.5 on FreeBSD
I've configured and built openmpi-1.8.5 on FreeBSD-11 with % ./configure --prefix /usr/local/openmpi-1.8.5 --disable-shared \ --enable-static --enable-mpirun-prefix-by-default This, of course, disables shared libraries and enables static libs. Now, when I go to build my program, I see % make -DMPI /usr/local/openmpi-1.8.5/bin/mpif90 -O2 -pipe -static -I/home/kargl/modules \ -o sasmp sasmp.f90 -L/home/kargl/lib -L. -L/usr/local/lib -L. -loa -ltgt \ -L/home/kargl/lib -L. -L/usr/local/lib -lm90 -llapack -lblas /usr/lib/libexecinfo.a(symtab.o): In function `symtab_create': /usr/src/lib/libexecinfo/../../contrib/libexecinfo/symtab.c:(.text+0x7f): \ undefined reference to `elf_version' /usr/src/lib/libexecinfo/../../contrib/libexecinfo/symtab.c:(.text+0x95): undefined reference to `elf_begin' The undefined symbols live in /usr/lib/libelf.a. In grepping through the Makefiles, I find LIBS = -lexecinfo -lm -lutil OPAL_WRAPPER_EXTRA_LIBS = -lm -L/usr/local/lib -lpciaccess -lexecinfo -lutil OMPI_WRAPPER_EXTRA_LIBS = -lm -L/usr/local/lib -lpciaccess -lexecinfo -lutil ORTE_WRAPPER_EXTRA_LIBS = -lm -L/usr/local/lib -lpciaccess -lexecinfo -lutil Where do I modify the the configure infrastructure to add -lelf to these variables? -- Steve
[OMPI users] OpenMPI on Windows without Cygwin
Is it possible to build OpenMPI for Windows not running Cygwin? I know it uses /dev/shm, so there would have to be something equivalent to that not in Cygwin. TIA. -- Walt Brainerd
