Dear OpenMPI users and developers, i'm using OpenMPI 1.4.3.
My question is about MPI_FIle_Real_all routine and files larger than 4 GB. Is this routine able to manage this case? Using the routine with 6 GB file the routine fails, retrieving an allocation error. Investigating more in depth with Totalview, the problem appears in a line 188 of ompi/mca/io/romio/romio/adio/ad_nfs/ad_nfs_read.c: MPI_Type_size(fd->filetype, &filetype_size); here there is an explicit cast to int that can causes the problem. Someone can help me? Thanks in forward. -- Ing.
