[mpich-discuss] Error with MPI_Spawn

[Nitel Muhtaroglu]

Hello,

I am trying to integrate PETSc library to a serial program. 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?

Kind Regards,
