Sergii, kudos, I am really impressed by your usage of cygwin.
I am redirecting your question to the cygwin list as it is more likely to find there an answer to process limit on cygwin 64. Regards Marco -------- Original Message -------- Subject: [OMPI users] Fwd: openmpi linking problem Date: Wed, 25 Jun 2014 18:19:50 +0100 From: Sergii Veremieiev Reply-To: Open MPI Users Dear Sir/Madam, I'm trying to run a parallel finite element analysis 64-bit code on my desktop with Windows 7, Cygwin, Open MPI 1.7.5, 64Gb RAM and 6-core Intel Core i7-3930K CPU via "mpirun -np 6 executable" command. The code runs fine, but if I increase the number of elements to a critical one (roughly more than 100k) the built-in Mumps library returns an error message (please see below). Can you possibly advise me what can be a problem? I have checked in Task Manager the code is using about 3-6Gb per process or about 20Gb in total, that is much smaller than the amount of physical memory available on the system 55Gb. Is there possibly a memory limit in Windows available per process? Thank you. Best regards, Sergii mpirun has exited due to process rank 1 with PID 6028 on node exiting improperly. There are three reasons this could occur: 1. this process did not call "init" before exiting, but others in the job did. This can cause a job to hang indefinitely while it waits for all processes to call "init". By rule, if one process calls "init", then ALL processes must call "init" prior to termination. 2. this process called "init", but exited without calling "finalize". By rule, all processes that call "init" MUST call "finalize" prior to exiting or it will be considered an "abnormal termination" 3. this process called "MPI_Abort" or "orte_abort" and the mca parameter orte_create_session_dirs is set to false. In this case, the run-time cannot detect that the abort call was an abnormal termination. Hence, the only error message you will receive is this one. This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). You can avoid this message by specifying -quiet on the mpirun command line.
