# Build options for Open64 Compiler on Linux x86-64 |
| 7 |
# first version tested on Fedore Core 4 x86-64 Opteron (Linux batsi) |
| 8 |
# updated and tested on acesgrid (Fedora Core 15), using: |
| 9 |
# module load open64 (Version 4.2.4) |
| 10 |
# Also tested with MPI on acesgrid, using: |
| 11 |
# module load open64 (Version 4.2.4) |
| 12 |
# and with mpich1: |
| 13 |
# module load mvapich |
| 14 |
# or with mpich2: |
| 15 |
# module load mvapich2 |
| 16 |
# or with openmpi: <== not yet tested |
| 17 |
# module load openmpi |
| 18 |
|
| 19 |
#------- |
| 20 |
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS |
| 21 |
# and generally, needs to increase the thread stack-size: |
| 22 |
# - sh,bash: |
| 23 |
# > export OMP_NUM_THREADS=2 |
| 24 |
# > export OMP_SLAVE_STACK_SIZE=400m |
| 25 |
# - csh,tcsh: |
| 26 |
# > setenv OMP_NUM_THREADS 2 |
| 27 |
# > setenv OMP_SLAVE_STACK_SIZE 400m |
