Hi, I am trying to solve a linear system of equations on a 4xIBM HS22 Blade setup (24GB+two 4 cores Intel Xeon). I am facing the following error during my computation, does anyone know what the problem is? ------------------------------------------------------------------------------------------------------------- INTERNAL ERROR: Invalid error class (71) encountered while returning from MPI_Recv. Please file a bug report. [proxy:0:[email protected]] HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb. c:928): assert (!closed) failed [proxy:0:[email protected]] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_ poll.c:77): callback returned error status [proxy:0:[email protected]] main (./pm/pmiserv/pmip.c:226): demux engine error waiting for event [proxy:0:[email protected]] HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb. c:928): assert (!closed) failed [proxy:0:[email protected]] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_ poll.c:77): callback returned error status [proxy:0:[email protected]] main (./pm/pmiserv/pmip.c:226): demux engine error waiting for event [mpiexec(a)ibm-bl01.ozun.int] HYDT_bscu_wait_for_completion (./tools/bootstrap/util s/bscu_wait.c:70): one of the processes terminated badly; aborting [mpiexec(a)ibm-bl01.ozun.int] HYDT_bsci_wait_for_completion (./tools/bootstrap/src/ bsci_wait.c:23): launcher returned error waiting for completion [mpiexec(a)ibm-bl01.ozun.int] HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pm ci.c:191): launcher returned error waiting for completion [mpiexec(a)ibm-bl01.ozun.int] main (./ui/mpich/mpiexec.c:405): process manager erro r waiting for completion ------------------------------------------------------------------------------------------------------------- Regards, -- Nitel

Hi, The short answer is yes, this is possible. I would suggest trying to run the included cpi example code in MPICH across both of your machines.

RPC - running parallel on two devices
by Hana Milani 02 Oct '13

Guys, I am a noob and I really don't know if it is right to ask this question here. If it is not, please accept my apology: There's a code written in fortran that I run it in parallel with mpich on the following devices: I have a laptopn Dell E6510. It has four real CPUs and 8GiB memory. I also have a PC it also has 4 CPUs and 8 GiB ram. On my laptop, I have fedora 19 and mpich. On the PC I have centos and mpich. I want to know if there is any possibility that I can use the facilities of these two computers simultaneously for running my program. I mean is it possible to use 8 CPUs and 16GiB ram of these two devices together in parallel at the same time? Thanks in advance for your help!
