Hello
I downloaded a precompiled version of 64-bit openmpi 1.6.2. I then include and link with the libraries and header files for my C++ application in Visual Studio 2010 64-bit. When I run my C++ code in Visual Studio 2010, I set up my MPI_Comm and MPI_Info without a problem. But when I call MPI_File_open, I get back an error code of 16 MPI_ERR_OTHER. Could you tell me why I cannot open an existing file with MPI? I do not run with mpirun, I am running the code with visual studio. It prints out that it created the process and gives it a rank. I just cannot open a file. Please help me. Julia
