In case of trouble


Up: Contents Next: Problems compiling or linking Fortran programs Previous: Other MPI Documentation

This section describes some commonly encountered problems and their solutions. It also describes machine-dependent considerations. Send any problem that you can not solve by checking this section to mpi-bugs@mcs.anl.gov. Please include:

* The version of mpich (e.g., 1.0.11)

* The output of running your program with the -mpiversion argument (e.g., mpirun -np 1 a.out -mpiversion)

* The output of 
uname -a
for your system. If you are on an SGI system, also 
hinv
* If the problem is with a script like configure or mpirun, run the script with the -echo argument (e.g., mpirun -echo -np 4 a.out ).

* If you are using a network of workstations, also send the output of bin/tstmachines or util/tstmachines.

Each section is organized in question and answer format, with questions that relate to more than one environment (workstation, operating system, etc.) first, followed by questions that are specific to a particular environment. Problems with workstation clusters are collected together as well.
