On WINDOWS platform, I am observing following error when executing "mpirun blacs_hello_example.exe" (example program to test BLACS taken from http://www.netlib.org/blacs/BLACS/Examples.html#HELLO)...
C:\blacs_examples> mpirun blacs_hello_example.exe calling blacs_pinfo()... forrtl: severe (157): Program Exception - access violation Image PC Routine Line Source libmpid.dll 6A8E2DC5 Unknown Unknown Unknown libmpid.dll 6A8E2C31 Unknown Unknown Unknown blacs_ex01.exe 00402357 Unknown Unknown Unknown libifcorert.dll 1002A1C1 Unknown Unknown Unknown [myhost1:15340] [[30379,0],0]-[[30379,1],0] mca_oob_tcp_msg_recv: readv failed:Unknown error (10054) -------------------------------------------------------------------------- mpirun.exe has exited due to process rank 0 with PID 528 on node vibgyor exiting improperly. There are two 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" This may have caused other processes in the application to be terminated by signals sent by mpirun.exe (as reported here). -------------------------------------------------------------------------- Environment: OS: Windows 7 64-bit Compilers: Visual Studio 2008 32bit and Intel ifort 32bit OpenMPI: OpenMPI-1.5.3 pre-built libraries and also with OpenMPI-1.5.2. locally built libraries BLACS: pre-built libraries taken from http://icl.cs.utk.edu/lapack-for-windows/scalapack/index.html#librairies Any idea on how to resolve this??? Thank you in advance. -Hiral
