-2045256448 offset is of the type MPI_OFFSET_KIND which seems insuficient to hold the correct size for the offset. So... am I condemned to write my own MPI data type so I can write the files? ideas... ? best regards, Ricardo Reis 'Non Serviam' PhD/MSc Mechanical Engineering | Lic

make a copy yourself and allow the original buffer to be freed. Thanks. So in an asynchronous write, the old buffer would only be available after the I/O ended. So maybe I really need to think to set some process aside just for I/O... Ricardo Reis 'Non Serviam' PhD candidate @ Lasef Computat

sh it. Yes, I know. But this should function if the Barrier would be working has supposed. I've seen it working previously and I'm seing it working in other MPI implementations (mvapich) So, what's the catch? Grande abraço a um conhecedor de Pessoa e habitante do país de Walt Whitman, Ricardo Reis
