Hi, I have two seperate issues but I believe they may be linked: 1. fpi.exe is hanging when run This is the example fortran available with the MPICH2 download. I compile the program through code::blocks with the GNU Fortran compiler with link library ~MPICH2\lib\fmpich2g and compiler search directory \MPICH2\include The program appears to compile fine with no errors/flags etc. When I run the program from the code::bloacks IDE it runs fine. But when in the command prompt (logged in as asministrator) the command mpiexec -n 4 fpi hangs. Note the same command for the c file (mpiexec -n 4 cpi) runs fine. 2. My Fortran program gives an error when run through mpiexec. Again, the program is compiled with the same settings as above. However, when using the command mpiexec -n 4 <myexefile> I receive the following error message job aborted: rank: node: exit code [: error message] 0: James-PC: 123 1: James-PC: -1073741819: process 1 exited with calling finalize 2: James-PC: -1073741819: process 2 exited with calling finalize 3: James-PC: 123 System Details: Windows 7 64 bit system but code::blocks and MPICH are 32 bit MPICH version is mpich2 1.4.1p1 Thanks in advance, James _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
