Hello, I've wanted to run MPI on a couple of PS3 here. According to a colleague who set it up, I had to set several HugePages. As the PS3 RAM is limited I had to allocate 2 HugePages. I ran HPL at first with the following command (out of a tutorial): mpirun --mca btl_openib_want_fork_support 0 -np 1 numactl --physcpubind=0 ./xhpl : -np 1 numactl --physcpubind=1 ./xhpl
Now as I had very little memory I had to disable some services. I did so (Wifi Service, Bluetooth, printing, unneeded). After running the same command again, I got the an error message (see below). Can anyone help me here, I have no idea what the error message actually means, and I can't find anything useful about it. It's running on Yellow Dog Linux, using OpenMPI 1.2.8 Cheers, Andreas Hoelzlwimmer Error Message: [PS02:04815] *** Process received signal *** [PS02:04815] Signal: Bus error (7) [PS02:04815] Signal code: (2) [PS02:04815] Failing at address: 0x4000ca78008 [PS02:04816] *** Process received signal *** [PS02:04816] Signal: Bus error (7) [PS02:04816] Signal code: (2) [PS02:04816] Failing at address: 0x4000ca78008 [PS02:04816] [ 0] [0x1003e8] [PS02:04816] [ 1] ./xhpl(HPL_hpalloc-0x17cc8c) [0x1001103c] [PS02:04816] [ 2] ./xhpl(HPL_pdtest-0x17da40) [0x100101f8] [PS02:04816] [ 3] ./xhpl(main-0x182f2c) [0x1000acdc] [PS02:04816] [ 4] /lib64/libc.so.6 [0x80ca0e966c] [PS02:04816] [ 5] /lib64/libc.so.6(__libc_start_main-0x1473e0) [0x80ca0e98e8] [PS02:04816] *** End of error message *** [PS02:04815] [ 0] [0x1003e8] [PS02:04815] [ 1] ./xhpl(HPL_hpalloc-0x17cc8c) [0x1001103c] [PS02:04815] [ 2] ./xhpl(HPL_pdtest-0x17da40) [0x100101f8] [PS02:04815] [ 3] ./xhpl(main-0x182f2c) [0x1000acdc] [PS02:04815] [ 4] /lib64/libc.so.6 [0x80ca0e966c] [PS02:04815] [ 5] /lib64/libc.so.6(__libc_start_main-0x1473e0) [0x80ca0e98e8] [PS02:04815] *** End of error message *** mpirun noticed that job rank 0 with PID 4815 on node PS02 exited on signal 7 (Bus error). 1 additional process aborted (not shown)
