Hi All, I have Petsc release version 3.9.2 configured with the following options:
Configure options --with-cc=mpiicc --with-cxx=mpiicpc --with-fc=mpiifort --download-fblaslapack=1 Now I want to use PCILU in my code and when I set the PC type to PCILU in the code, I get the following error: [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: See http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html for possible LU and Cholesky solvers [0]PETSC ERROR: Could not locate a solver package. Perhaps you must ./configure with --download-<package> [0]PETSC ERROR: See http://www.mcs.anl.gov/petsc/documentation/faq.html for trouble shooting.

I am wondering what is the best way to reconfigure Petsc to download and use the appropriate package to support PCILU? You advice is highly appreciated. -- *Najeeb Ahmad* *Research and Teaching Assistant* *PARallel and MultiCORE Computing Laboratory (ParCoreLab) * *Computer Science and Engineering* *Koç University, Istanbul, Turkey*
