c474f7219d Jean*0003 # Build options for gfortran compiler (GNU) on Linux AMD64 platform
0004 #
1e25bc2551 Jean*0005 # Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8
0006 # up to gcc-gfortran v10.2.1 as shipped with Fedora Core 33
c474f7219d Jean*0007 #
1e25bc2551 Jean*0008 # OpenMP : Tested with gcc-gfortran v4.3.2 with FC 10 (on dickens)
0009 # with gcc-gfortran v4.4.5 with FC 13 (on baudelaire)
0010 # with gcc-gfortran v7.5.0 with Ubuntu 18 LTS (on villon)
0011 # up to gcc-gfortran v10.2.1 with FC 33 (on batsi)
c474f7219d Jean*0012 #
1e25bc2551 Jean*0013 # MPI : Tested on engaging, using:
0014 # module load gcc (Version 4.8.4)
0015 # module add mvapich2/gcc/64/2.0b
c474f7219d Jean*0016 # and on baudelaire.csail.mit.edu (FC13), using:
0017 # export MPI_GCC_DIR=/srv/software/gcc/gcc-packages/gcc-4.4.5/mpich2/mpich2-1.3
0018 # export MPI_INC_DIR=$MPI_GCC_DIR/include
0019 # export PATH=$MPI_GCC_DIR/bin:$PATH
1e25bc2551 Jean*0020 # and with openmpi, on several platforms (e.g, with Ubuntu)
c474f7219d Jean*0021
7ce1a97e55 Jean*0022 #-------
78812250ef Jean*0023 # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
7ce1a97e55 Jean*0024 # and generally, needs to increase the thread stack-size:
0025 # - sh,bash:
0026 # > export OMP_NUM_THREADS=2
0027 # > export GOMP_STACKSIZE=400m
0028 # - csh,tcsh:
0029 # > setenv OMP_NUM_THREADS 2
0030 # > setenv GOMP_STACKSIZE 400m
