5  #  tested on faulks, 20030818  #  build options used with the Intel compiler, version 8 and 9,
6    #  for the daily testing on ACES (which are initiated by cron jobs
7    #  on the "ao" head node).
8  #  #
9  #  Build options for the intel 8.0 fortran compiler  #  Needs the appropriate module commands,
10  #  the compiler is now called ifort (not ifc) and it appears to  #  and DON'T FORGET to set environment variable MPI_INC_DIR to the include
11  #  need -DWORDLENGTH=1 and not -DWORDLENGTH=4 (which is what ifc 6.0) used to have.  #  directory of the selected MPI implementation
12    #
13    #-- using default intel (v8.1) and default mpich/intel:
14    #    module add mpich/intel
15    #    module add netcdf/3.6.1/icc
16    #   e.g.(sh,bash):
17    #    export MPI_INC_DIR='/usr/local/pkg/mpich/mpich-intel/include/'
18    #   (and run using mpirun -machinefile my_list_of_nodes)
19    #  
20    #-- using intel v9.0 and mpich2-intel, in this order:
21    #    module add ifc/9.0.021 icc/9.0.021 intel/9.0
22    #    module add mpich2/1.0.3/intel
23    #    module add netcdf/3.6.1/icc
24    #    module add mpiexec             (<-- to run with mpiexec)
25    #   e.g.(sh,bash):
26    #    export MPI_INC_DIR='/usr/local/pkg/mpich2/mpich2-1.0.3/intel/include/'
27    #   (and run using mpiexec)
28    #
29    #-- Multi-Threading with OpenMP:
30    #  -several problems with earlier version of ifort (including some version 8)
31    #  -with version 9 and more recent one:
32    #   1) compile with genmake2 -omp option ;
33    #   2) needs to set environment variable OMP_NUM_THREADS, and generally,
34    #      needs also to increase the thread stack-size:
35    #     (sh, bash) > export OMP_NUM_THREADS=2  
36    #                > export KMP_STACKSIZE=400m
37    #     (csh,tcsh) > setenv OMP_NUM_THREADS 2
38    #                > setenv KMP_STACKSIZE 400m
39    #  NOTE: set KMP_STACKSIZE in .bashrc/.profile/.cshrc/.tcshrc is the easiest
40    #  way (I found) to set it for all proc; not an issue (?) for OMP_NUM_THREADS
41    
42    # Notes: the PBS -V option for exporting environment variables does not work
43    #        => need to set all env var on compute nodes
