Hi, I have installed OpenStack Folsom on Ubuntu and I want to run HPCC benchmark on that. For this reason I have created an image with OpenMPI 1.6.4 and Atlas 3.10.1 and HPCC 1.4.2 I can run the test on single instance and from one instance on another. But the problem arise when I want to run the test simultaneously on two instances with: mpirun -np 2 --hostfile myhosts hpcc then I receive the following error:
[ubuntu-benchmark:03607] *** Process received signal *** [ubuntu-benchmark:03607] Signal: Segmentation fault (11) [ubuntu-benchmark:03607] Signal code: Address not mapped (1) [ubuntu-benchmark:03607] Failing at address: 0x26ea000 [ubuntu-benchmark:03607] [ 0] /lib/x86_64-linux-gnu/libc.so.6(+0x364a0) [0x2b92c5ba54a0] [ubuntu-benchmark:03607] [ 1] hpcc(HPCC_Power2NodesMPIRandomAccessCheck_LCG+0xa46) [0x4531a6] [ubuntu-benchmark:03607] [ 2] hpcc(HPCC_MPIRandomAccess_LCG+0x87a) [0x427b3a] [ubuntu-benchmark:03607] [ 3] hpcc(main+0xd1b) [0x409e1b] [ubuntu-benchmark:03607] [ 4] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x2b92c5b9076d] [ubuntu-benchmark:03607] [ 5] hpcc() [0x40a9fd] [ubuntu-benchmark:03607] *** End of error message *** [ubuntu-benchmark][[17032,1],0][btl_tcp_frag.c:215:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv: readv failed: Connection reset by peer (104) -------------------------------------------------------------------------- mpirun noticed that process rank 1 with PID 3607 on node ubuntu-benchmark02 exited on signal 11 (Segmentation fault). -------------------------------------------------------------------------- I have tested different scenarios (for example installing openmpi or mpich2 via apt-get) but every time I still receive the same error. Now I think one possible problem source could be from OpenStack itself. I don't know maybe memory allocation strategy (in worse case can openstack fake the allocated memory?) or something like that (I have tested both KVM and QEMU). Any idea would be helpful for me. Thanks for your consideration. Regards, Reza
