Hi, I was looking for some performance enhancements around the linear solver area and I was curious about this USE_HASH_TABLE option.
I wonder what scale of improvement I should expect and I got follow error during my first attempt. [0]PETSC ERROR: --------------------- Stack Frames ------------------------------------ [0]PETSC ERROR: Note: The EXACT line numbers in the stack are not available, [0]PETSC ERROR: INSTEAD the line number of the start of the function [0]PETSC ERROR: is given. [0]PETSC ERROR: [0] MatSetValuesBlocked_MPIBAIJ_HT line 470 /d/dev01/chungh/lib2/petsc-3.5.2/src/mat/impls/baij/mpi/mpibaij.c [0]PETSC ERROR: [0] MatSetValuesBlocked line 1636 /d/dev01/chungh/lib2/petsc-3.5.2/src/mat/interface/matrix.c [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- I wonder anything I didn't do right.. Thanks, Kan -- *Cheers*
