In the last topic I read it was asked more that once to zip the files and I did it.. By the way, this is the first error: Assertion failed in file helper_fns.c at line 361: ((((char *) sendbuf + sendtype_true_lb))) != NULL internal ABORT - process 2 Starting from the second execution I get: ===================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = EXIT CODE: 139 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES ===================================================================================== HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb.c:928): assert (!closed) failed HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status main (./pm/pmiserv/pmip.c:226): demux engine error waiting for event HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb.c:928): assert (!closed) failed HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status main (./pm/pmiserv/pmip.c:226): demux engine error waiting for event HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb.c:928): assert (!closed) failed HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status main (./pm/pmiserv/pmip.c:226): demux engine error waiting for event HYDT_bscu_wait_for_completion (./tools/bootstrap/utils/bscu_wait.c:70): one of the processes terminated badly; aborting HYDT_bsci_wait_for_completion (./tools/bootstrap/src/bsci_wait.c:23): launcher returned error waiting for completion HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pmci.c:191): launcher returned error waiting for completion main (./ui/mpich/mpiexec.c:405): process manager error waiting for completion Regards, Danilo -----Original Message----- From: Wesley Bland <[email protected]> To: discuss <[email protected]> Sent: Fri, Jun 28, 2013 3:22 pm Subject: Re: [mpich-discuss] mpi assertion error Can you just copy paste your error into the email? Most of us will probably not be all that excited about opening up strange tarballs attached to an email. Also, we get these emails on our phones and tablets where unzipping source code isn't as much of an option.

This app was firstly executed on a cluster on which it was installed 2007 mpi version (don't remember the package name) and then adapted for a different cluster with mpi 1.4.1 (had to change the scatter/gather because in the previous version I could use the same buffer for both sendbuff and recvbuff). By the way, when executing with 2 processes it works fine. When trying with 4/8/16/32 and so on it gives firstly an assertion error as shown in the file attached, and starting from the second time you try to run it on more than 2 procs it gives error code 139. The error I'm talking about appears just when you run it with "realDim=16384" (it means that you have 16384 rows and 16384x2 columns since it is designed for real/imaginary numbers). I know the code is working since it was all ok on the previous cluster (even with 4-8-16-32 procs) and I can't find out which is the problem now.. Can you help? As said attached you can find my application as well as the errors appearing and mpi info..
