Dear Yves,

actually I found out that these configure options  ...

../configure FC_LDFLAGS_OPT="-bmaxstack:250000000 -bmaxdata:2000000000 
-bloadmap:loadmap"

do the same job as the ones that I proposed before in terms of memory 
allocation, but should lead
to a faster executable, since the previous options (FCFLAGS= ...) were 
overwriting some optimization flags.
So, the new configure options (see above) should speed up the calculations 
quite a bit. (at least in my case)

Best regards,
Peter
