Notes on downloading and installing WinMPICH on NTs: 1. download WinMPICH from the Missicippi State web site into a final destination directory (e.g. c:\winmpich) 2. read winmpich.wrt using WordPad or winmpich.txt using text editor for installation and help nots 3. currently, a copy of the distribution is saved under \\rios\faculty\software\winmpich 4. the current version works under MSVC++ 4.0. One can try to compile for 5.0. It should work without much change. Notes on using WinMPICH on NTs 1. when compiling: in VC++ 4.0, choose Build|Setting, check the "link" tab, add winmpich.lib to the Object/Library modules choose Tools|Options, check the "Directories" tab, select "include files" and specify the MPI include directory, e.g c:\winmpich\include, then select "library files" and sepcify the MPI library directory, e.g c:\winmpich\library 2. Then you should be able to compile the program. 3. When executing, go to the DOS prompt, go do the project directory, and type mpirun -np # foo.exe where # is the number of processors involved, and foo.exe is the executable file name 4. In the same directory, a .cfg file has to be there. The .cfg file should have the same name as the executable, e.g. test.cfg. The .cfg file contains the name of the computers and the executable files.
