[mpich-discuss] Help Mpich2

[angelo pascualetti]

Good afternoon.
I am installing the WRF numerical model in a single computer with 2 cores
and 2 threads and I see that there are 3 ways to run: Serial, OpenMP and
Dmpar.
Mpich (Dmpar option) can be run on a single computer?.
In other words, if I run the program with mpich indicating the two nuclei is
faster than with openmp?
How many processes (-np) should tell mpich to be faster than openmp?
I'm running as follows:

export CC=icc
export FC=ifort
./configure --prefix=$HOME/Mpich2
make
make install
cd $HOME
touch .mpd.conf
chmod 600 .mpd.conf
gedit .mpdhost y escribir:
MPD_SECRETWORD=angelo1903
mpdboot -v -n 1 --ncpus=2
mpirun -np 2 ./run.exe


In advance thank you very much.
