I have been informed that dft allow parallelization, so that it is interesting
to go on.
Hi Jo: I have also been indicated - by people who probably do not know debian
but are masters of Dalton - to compile mpich, whereby all libraries are
compiled at 64bit on my system. Do the above packages do the job, with no
need to compile mpich? Having examined the packages I expect Yes.
That depends. MPICH is fairly generic, and at compile-time, you need to
specify which parallelization model to use - for example, a work, we use
MPICH-GM, which is for use on Myrinet high-speed proprietary
interconnects. If you want to use shared memory (i.e. MPI on a local
machine, not over a network), then the prepackaged *mpich-shmem*
packages are fine. If you want to use gigabit ethernet over TCP/IP on a
cluster, you want the vanilla mpich packages, or *mpich-mpd* packages if
your cluster provides an mpich execution daemon.
I would *never* compile something if it can be avoided - why repeat work
someone else has already done? The advice you received about 64-bitness
is false, as almost all packages on AMD64 debian are already 64-bit
(rare exceptions are 32-bit compatibility libraries, and things like GRUB)
