[petsc-users] Optimization time parallel version of structural solver

Dear PETSc team, I'm currently working on the parallelization of the assembling of a system, previously assembled in a serial way (manual), but solved using PETSc in parallel. The problem I have is that when comparing computational time with the previous implementation, it seem that the paral

[petsc-users] Way to remove zero entries from an assembled matrix

Hello PETSc team: I'm doing the parallelization of the assembling of a system, previously assembled in a serial way (manual), but solved using PETSc in parallel. Therefore I have the old assembled matrix to compare with the one assembled with PETSc. While doing the assembling of the matrix,
