[petsc-users] PETSC ERROR: Caught signal number 15 Terminate

[Aron Ahmadia]

"But I encounter a new problem, the situation is:****

1, the matrix is big, and can be partitioned to several blocks;****

2, started several threads to handle each block of matrix;****

3, integrated all block matrices together."****

You should be using PETSc+MPI to handle this distribution for you.
 Threading will not get around any memory limits for a single process that
your system may have.
