parallel computing

hi all, Could someone tell me whether it is possible to run parallel codes on a Core 2 Duo PC, using MPICH on Campaq visual fortran? does it make use of the 2 core processors? thanks in advance!

If you can get a Compaq Visual Fortran program to link to some version of mpich then certainly you can run it on Core 2 Duo and it will make use of both cores.

hi, many thanks!

You can also use gfortran (Linux, Windows, Mac) or Intel Fortran compiler (this is free only for Linux if I remember correctly).

Dear sir:
could you please tell me how to compile a mpich with fortran in windows system.
thank you very much

I am do not set the faces boundary of wall,but the wall was appeared in the fluent.how to remove the wall in the fluent?
thank you ,your friends fei.

First install mpich on your Windows machine, then read the documentation.

In general it is easier to do CFD on a Linux machine, because you have a lot of free tools (compilers, mesh generators ...).

Hi Guys,

I've worked with mpich for some time and now I think that openMP is better suited for SMP. It is easier to implement and to use. MPICH is better for DMP and harder to implement.

ya, openmp's easier and better for shared memory. however, i doubt compaq VF can use openmp. I believe intel's ifort can. correct me if i'm wrong.

gfortran can use OpenMP on Linux/Windows/FreeBSD.

you can use Cilk language.

hi, just wanna share, I did parallel computing on 2 CPUs with 4 Cores in each of them. As I remember, what you need is download the suitable mpich version, install it, target it on your computer path, set your fortran library and link, put parallel command on input data (if needed) and execute it on the command prompt. correct me if its wrong.
