6  # Build options for Fedore Core 4 x86-64 Opteron  # Build options for Open64 Compiler on Linux x86-64
7  # tested on (Linux batsi.mit.edu 2.6.14-1.1656_FC4smp #1 SMP Thu Jan 5 22:26:33 EST 2006 x86_64 x86_64 x86_64 GNU/Linux) system 20071121  #  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)

11    #-------
12    # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
13    #    and generally, needs to increase the thread stack-size:
14    #   -  sh,bash:
15    #     > export OMP_NUM_THREADS=2
16    #     > export OMP_SLAVE_STACK_SIZE=400m
17    #   - csh,tcsh:
18    #     > setenv OMP_NUM_THREADS 2
19    #     > setenv OMP_SLAVE_STACK_SIZE 400m
