Hi all! Today, I observed a really funky behavior of my stock ``` $ mpiexec --version mpiexec (OpenRTE) 1.6.5
Report bugs to http://www.open-mpi.org/community/help/ ``` on Ubuntu 14.04. When running one of my test codes with ``` $ mpiexec -n 2 ioTest [...] ``` all is fine. If instead I use the full path of mpiexec, I get a different behavior ``` $ /usr/bin/mpiexec -n 2 ioTest [...] (exception thrown) ``` I was puzzled, so skimmed the manpage and found that the `--prefix` option might have something to do with it. I played around and got ``` $ /usr/bin/mpiexec --prefix . -n 2 ioTest [fuji:21003] *** Process received signal *** [fuji:21003] Signal: Segmentation fault (11) [fuji:21003] Signal code: Address not mapped (1) [fuji:21003] Failing at address: 0x1000000dd [fuji:21003] [ 0] /lib/x86_64-linux-gnu/libpthread.so.0(+0x10340) [0x7f12e4069340] [fuji:21003] [ 1] /lib/x86_64-linux-gnu/libc.so.6(_IO_vfprintf+0x1d13) [0x7f12e3cde8f3] [fuji:21003] [ 2] /lib/x86_64-linux-gnu/libc.so.6(__vasprintf_chk+0xb5) [0x7f12e3d9e035] [fuji:21003] [ 3] /usr/lib/libopen-rte.so.4(opal_show_help_vstring+0x343) [0x7f12e43043e3] [fuji:21003] [ 4] /usr/lib/libopen-rte.so.4(orte_show_help+0xaf) [0x7f12e42a5faf] [fuji:21003] [ 5] /usr/bin/mpiexec() [0x403ab3] [fuji:21003] [ 6] /usr/bin/mpiexec() [0x40347d] [fuji:21003] [ 7] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f12e3cb4ec5] [fuji:21003] [ 8] /usr/bin/mpiexec() [0x403399] [fuji:21003] *** End of error message *** Segmentation fault (core dumped) ``` That's tough! Should I try to reproduce this with a more recent version? Any idea what the reason for the different behavior of `mpiexec` and `/usr/bin/mpiexec` might be? Cheers, Nico
