Dear Petsc: I'm trying on Petsc iterative solver(KSPCG & PCJACOBI), but it's strange that the two functions "MatCopy" and "MatSetValue" consume most of runtime, and the functions were not called frequently, just several times.
My libpetsc.a is built as follows: 1, /config/configure.py --with-mpi=0 --with-debugging=0 -with-log=0 -with-info=0 2, make all; It's very appreciated to get your reply. Thanks a lot, Debao ________________________________ -- The information contained in this communication and any attachments is confidential and may be privileged, and is for the sole use of the intended recipient(s).
