[OMPI users] MCA crs: none (MCA v2.0, API v2.0, Component v1.6.3)
Hi all, I got this message when I issued this command: root@node1:/home/abolap# ompi_info | grep crs MCA crs: none (MCA v2.0, API v2.0, Component v1.6.3) The installation looks okay and I have reinstalled but still got the same issue. When I searched for the solution I found out that this is a bug which Josh has filed (https://svn.open-mpi.org/trac/ompi/ticket/2097) but I cannot see the solution or workaround. This is the initial post - http://www.digipedia.pl/usenet/thread/11269/6087/#post6031 Please assist. Regards, Ifeanyi

[OMPI users] checkpointing of NPB
Dear, Please help. I configured the open mpi and it can checkpoint HPL. However, whenever I want to checkpoint NAS parallel benchmark it kills the application without informative message. Please how do I configure the openmpi 1.6 to checkpoint NPB? I really need a help, I have been on this issue for the past few days without solution Regards, Ifeanyi
[OMPI users] checkpointing
Hi Please help. I have installed openmpi-1.6, I have also tested the installation with different mpi applications and my application executed successfully. Whenever I ran NPB-3.3 LU without checkpointing, NPB-3.3 completes successfully. however whenever I checkpointing the application, it aborts without checkpointing with the following error "mpirun noticed that process rank 1 with PID 1048 on node node1 exited on signal 10 (User defined signal 1). -- 2 total processes killed (some possibly by mpirun during cleanup)" However, when I ran HPL and checkpoint - checkpointing was successfully completed as well as the application. I have tried to resolved this without success. Please I need assistance - I am new user of open mpi. Regards, Ifeanyi
Re: [OMPI users] checkpointing/restart of hpl
Thanks Constantinos. I have gone through the site you sent to me, however whenever I want to enable FT, it will not be enabled. this is what I got. /openmpi-1.6# ./configure --enable-ft-thread --with-ft=cr --with-blcr=/usr/src/blcr-0.8.2 #FT Checkpoint support: no (checkpoint thread: no) "FT Checkpoint support: no (checkpoint thread: no)" Please is there a special way to enable the FT? I also want test with real application that runs for about 30 mins but I cannot easily lay my hands on any. Please help. Thanks in advance.
