[mpich-discuss] Error with MPI_Spawn

[Jeff Hammond]

This is the wrong way to use PETSc and to parallelize a code with a
parallel library in general.

Write the PETSc user list and they will explain to you how to
parallelize your code properly with PETSc.

The idea is that the serial program creates a linear equation system and then calls PETSc solver by MPI_Spawn and then solves this system in parallel. But when I execute MPI_Spawn the following error message occurs and the solver is not called. I couldn't find a solution to this error. Does anyone have an idea about it?
