[FLASH-USERS] Compile Flash on NERSC Cori

[Lu, Yingchao]

Hi Hao,

The petsc module on Cori includes an HYPRE library. However, we have found that HYPRE in petsc has memory cleaning problems. So, I would suggest building and installing HYPRE on your own. After installation you need to include the following lines in Makefile.h:
LIB_HYPRE = -L${HYPREHOME}/lib -lHYPRE
FFLAGS_HYPRE = -I${HYPREHOME}/include
CFLAGS_HYPRE = -I${HYPREHOME}/include
where ${HYPREHOME} is the environment variable pointing to where HYPRE is installed.

The HYPRE installation guide and source code can be found on GitHub: https://github.com/hypre-space/hypre. Setting these environment variables before running configure script may be useful for building HYPRE on Cori:
export FC=ftn
export CC=cc
export CXX=CC
_COMPFLAGS="-O3"
export FFLAGS="${_COMPFLAGS}"
export F77FLAGS="${_COMPFLAGS}"
export LDFLAGS="${_OPENMP}"
export CXXFLAGS="${_COMPFLAGS}"
export CFLAGS="${_COMPFLAGS}"

Best,
Yingchao

Subject: [FLASH-USERS] Compile Flash on NERSC Cori
Hello all,

Has anyone compiled Flash on NERSC Cori?
Flash4.6.2 only contains sites up to edition.nersc.gov, and Cori is not in the list. The Edison system uses Cray XC30 which is different from Cori (Cray XC40). It seems the link to HYPRE is missing in that makefile.h when I tried compiling on Cori. I got the following error.

Is there a way that allows me to compile it on Cori by modifying the makefile.h? The makefile.h is attached. Thanks for help!

Best,
Hao
