Hi,
is it possible to have MPI code that uses MPI I/O functions works under windows?
Which version (package) of MPI can we try for that?
definitely possible. MS-MPI implements the MPI-IO routines as does Intel MPI. I don't have any experience with parallel I/O on Windows, but I think you're going to find file system client support a bigger challenge than MPI-IO support.
:) We are definitely binded to MPI I/O functions to read/write even in sequential mode... We are then happy to look for a zero lines of code solution to support windows for our software... Otherwise, we would have to implement all of MPI_Get_address(x,y) MPI_File_write_at(a,b,c,d,e,f) MPI_File_read_at_all(a,b,c,d,e,f) MPI_File_write_all_begin(a,b,c,d) MPI_File_write_all_end(a,b,c) MPI_File_write(a,b,c,d,e) MPI_File_read_all_begin(a,b,c,d) MPI_File_read_all_end(a,b,c) MPI_FILE_delete MPI_Info_set MPI_Info_free MPI_Info_create to work in sequential, which is feasible too...
I don't know what the consistency semantics of SMB/CFS are: when are writes from one client visible to another?
Can't tell... when I used windows for the last time I was so younger! :) Thanks for the answer! Eric _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
