[petsc-users] Building apps on Cori

[^PNNL GridPACK Account]

Hi,

We’ve got some users of our GridPACK package that are trying to build on the Cori machine at NERSC. GridPACK uses CMake for its build system and relies on Jed Brown’s FindPETSc.cmake module, along with the FindPackageMultipass.cmake module to identify PETSc. The tests for PETSc are currently failing with

-- Checking PETSc ...
-- petsc_lib_dir /global/u1/s/smittal/petsc/arch-linux2-c-debug/lib
-- Recognized PETSc install with single library for all packages

-- Configuring incomplete, errors occurred!

We have code in the CMakeLists.txt file to identify a Cray build and set the MPI_LIBRARY variable to “” instead of NOTFOUND but that may be failing. The PETSC_LIBRARY_SINGLE error is new and one that I haven’t seen in past attempts to build at NERSC. My recollection was that the FindMPI module was not geared towards identifying the MPI compiler wrappers on Crays and that had a tendency to mess everything else up.

Have you seen these kinds of problems recently and if so, has anyone come up with a solution?
