[Ncep.list.wwatch3.discussion-group] WW3 : comp.tmpl and link.tmpl based on cmplr.env

[Mickael Accensi]

Hi all,


Here is a quick mail to explain how the new template is working for 
comp/link on WW3


There is a new comp and link file that should be the only one remaining 
for the public release :

*comp.tmpl* and *link.tmpl*


using this compiler environment will create the .out and.err in tmp 
directory to easily find the errors and warnings.


_How to use it with w3_setup:_

*common compiler available : mpt, intel, gnu, pgi

*additional debug sufix    : _debug

*additional cluster prefix : zeus_ and datarmor_


_examples : _

w3_setup .. -c *mpt *

w3_setup .. -c *intel*

w3_setup .. -c *pgi*

w3_setup .. -c *gnu*

# add suffix to enable *debugging options* (available for 
mpt/intel/gnu/pgi compilers)

w3_setup .. -c mpt*_debug*

# add prefix to enable *cluster specific options* (done for datarmor and 
zeus)

w3_setup .. -c *datarmor_*mpt_debug


As it's a transitional way of do, it is highly recommended
to all the partners to try it and if needed add their own
cluster specific options.

To do it, just compile and run ww3 using the comp option mpt, intel, pgi 
or gnu depending on your usual compiler.

if it's not working or if results are different, you will need to edit 
*cmplr.env* in model/bin directory

_-> you can overwrite the compiler to use (example done for pgi on zeus)_

   # zeus compiler
   if [ ! -z "$(echo $cmplr | grep zeus)" ] ; then
     comp_seq='ftn'
     comp_mpi='ftn'
   fi


_-> you can append or replace comp/link options (example done for pgi on 
zeus and datarmor)_

   # system-dependant options
   if [ ! -z "$(echo $cmplr | grep zeus)" ] ; then
     optc="$optc -fastsse"
     optl="$optl -fastsse"
   elif [ ! -z "$(echo $cmplr | grep datarmor)" ] ; then
     optc="$(echo $optc | sed 's/O3/O2/')"
     optl="$optl"
   else
     optc="$optc"
     optl="$optl"
   fi

To keep both ways to use the comp/link with  ".tmpl" and 
".user-defined", you must also update w3_setup with your cluster name :

# 3.c Setup comp & link files

_-> add a line with your cluster name for comp and link sections 
(example done for all compilers for zeus and datarmor)_

        [ "$cmplr" == "datarmor_intel" ] || [ "$cmplr" == 
"datarmor_intel_debug" ]   || \



I'll be happy to help if you face troubles to do it.

Mickael
