Hi,<br> freefem++ is a free software for fluid dynamics which is built under C++. It has freefem++-mpi.exe (64 bit) as a utality to run its code for parallel processing by using MPI. I tried its examples and gets error as mentioned earlier. Howerver, it works well with MS-MPI (Microsoft MPI) while it hange with MPICH2 (64 bit).<br><br> <BR><div><div id="SkyDrivePlaceholder"></div>> Date: Tue, 25 Sep 2012 10:51:56 -0500<br>> From: jayesh@mcs.anl.gov<br>> To: marco.degregorio@iet.unipi.it<br>> CC: mpich-discuss@mcs.anl.gov<br>> Subject: Re: [mpich-discuss] MPI 64 bit for 64 bit code on windows7 64 bit<br>> <br>> Hi,<br>> If you can give us a simple test case that shows the problem it would be useful (The smallest fortran program, test.f, that compiles and shows the problem).<br>> <br>> (PS: A couple of lines of fortran code that shows the problem is what we need.)<br>> Regards,<br>> Jayesh<br>> <br>> ----- Original Message -----<br>> From: "Marco De Gregorio" <marco.degregorio@iet.unipi.it><br>> To: "Jayesh Krishna" <jayesh@mcs.anl.gov><br>> Cc: mpich-discuss@mcs.anl.gov<br>> Sent: Tuesday, September 25, 2012 7:01:35 AM<br>> Subject: Re: [mpich-discuss] MPI 64 bit for 64 bit code on windows7 64 bit<br>> <br>> <br>> Hi, <br>> <br>> I am sorry, but I don't understand.

I use Visual Studio 2008 and Intel Fortran 11. <br>> I have always used 32 bit MPI successfully. <br>> Now I need to switch my code to 64 bit. First of all I uninstalled 32 bit MPICH2 and I installed mpich2-1.4.1p1-win-x86-64. <br>> I have several problems. <br>> When I launch my program, the first value of some integer array ( block_lengths ) changes sign after some MPI_GET_ADDRESS and I have an error message.

The problem is with a mpi_send and mpi_receiver. <br>> <br>> address is defined as INTEGER(KIND = MPI_ADDRESS_KIND) :: address(SIZE) , but write(*,*) MPI_GET_ADDRESS returns 4. <br>> <br>> In the mpif.h I found: <br>> INTEGER MPI_ADDRESS_KIND, MPI_OFFSET_KIND <br>> PARAMETER (MPI_ADDRESS_KIND=8) <br>> PARAMETER (MPI_OFFSET_KIND=8) <br>> <br>> There is a mistake. <br>> <br>> Do you have any idea to help me?? <br>> <br>> With 32 bit MPICH2 and 32 bit code I don't have error. <br>> If I try mpiexec -n 1 code_64bit.exe , the 64 bit code works fine. <br>> <br>> Thank you, <br>> regards, <br>> <br>> <br>> -- <br>> <br>> <br>> Ing.
