Submitting bug reports


Up: Problems Next: Problems configuring Previous: Problems

Any problem that you can't solve by checking this section should be sent to mpi-bugs@mcs.anl.gov. Please include:

* The version of MPICH (e.g., 1.1.0)

* 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. The program tstmachines is discussed in the Users Guide.

If you have more than one problem, please send them in separate messages; this simplifies our handling of problem reports.

The rest of this section contains some information on trouble-shooting MPICH. Some of these describe problems that are peculiar to some environments and give suggested work-arounds. 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.
