Hi, Are you able to run any other MPI programs? Try running the example program, cpi.exe (C:\Program Files\MPICH2\examples\cpi.exe), to make sure that your MPICH2 installation works. Installing MPICH2 on Windows 7 typically requires you to uninstall any previous versions of MPICH2, launch an administrative command promt and run "msiexec /i mpich2-installer.msi" to install MPICH2.

I guess that they are already compiled... The .exe files are integrated into a software, and accessed from menus inside it. When I run one of the programs, the answer is actually "unable to query host". At the end, the process is not realised. It seems that this 'host' question is a problem to the software... Sincerely, Ben.

Hi, You can download MPICH2 binaries for Windows at http://www.mpich.org/downloads/ . You need to compile your MPI programs with MPICH2 to make it work. I would recommend recompiling your code after you install MPICH2 (If you have MPI program binaries pre-built with MPICH2 - instead of compiling them on your own - make sure that you install the same version of MPICH2 that was used to build the binaries). The wmpiregister program has a bug and you can ignore this error message ("...unable to query host"). Can you run your MPI program using mpiexec from a command prompt?

Regards, Jayesh

Hello,

I'm not very good at computing, but I would like to install Mpich2 on windows 7 - 64 bits. There is only one pc, with one user plus the admin, and a simple core processor.

I would like to know if it's mandatory to have compiling softwares with it to make it work, whereas it is asked in this case only to make run another software, and not for compiling (that would maybe save some disk space and simplify the installation) ?

My second issue is that I must be missing something about the server configuration. I have installed Mpich from the .msi file, then configured the wmpiregister program with the Domain/user informations.

There is this message displayed when trying to connect in the 'configurable settings' window : 'MPICH2 not installed or unable to query the host'.

What is the host actually ?

I know I am starting from very far, I am sorry for these very simple questions. Thanks if you can reply me, that would certainly save me some long hours of reading and testing ;)

sincerely,

Ben _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
