Hi everyone,
Sorry if my question is very similar to one recently asked by Eric
Circlaeys, but I'd like
to go one step further...
I use IBM's XLC/XLF under MacOSX Server 10.3.5. and I need fortran
support,
so I recompiled the lam-mpi libs (7.1 version, with 7.1.1, I did not
tried), very simply:
./configure CC=xlc FC=xlf FFLAGS=-qextname --prefix=/usr/local/lam-7.1
--with-trillium --disable-tv-queue --with-memory-manager=none
Things work. Ok. But I would like to improve performances.
What would you suggest (apart adding CFLAGS=-O3) ?
What is the configure command issued for the package (.dmg) distributed
?
Does it use gcc or another C compiler ?
Thanks very much in advance,
--
Christian
