Thank you very much, Shaun! Ok, now I realise it's really stupid that I was trying so hard to get the result that I wanted :-) Well, it seems it's not a problem if I'm just reading with MPI_File_read and writing with MPI_File_write, but if I try to do some calculations with the data I read, it doesn't work... Do you maybe have some idea how one can deal with this ( I have an input file for my project - much larger code than the sample I gave last time - consisting of integers, doubles, characters and so on... Maybe it's a silly question, but can I convert my input file somehow into something so that it works? :-) Any ideas would help. Thanks again. Cheers, Jovana
