No. This is a 64bit machine and if I write the file normaly (like just
using Fortran open/write/close) it works without problem (I just got a
3.5Gb file this way).
If try to use 2 processes it will also spit a 3.5 Gb file (because each
will be writing a chunk smaller than the 2.1 Gb "limit" ?)
I haven't tried to replicate the same program in C, I must admit
