I just downloaded the new Intel Fortran compiler.
I installed it on a RH 9 box and i tested it with the code reported at the end of this post.
Previously, ifc 7.1 did not have any problem on the same box with "unformatted" writes and reads. "binary" format, on the other hand, gave a strange problem.
I had no write/read problem with files less than the disk cache but it crashed at the first read from a (I suppose) correctly written file larger than the disk cache. I suppose it's something related to actual disk access. I never cared about it and I used unformatted files, which worked well.
Now, with ifort I always get a "maximum file size exceeded" with both uformatted and binary i/o when the size of the file being written exceeds 2GB. The message is in Italian (my native language), so I suppose it is cast by a localized library, not by ifc library routines.
Can anyone test my code and check if it works with Intel Fortran 8, with both "unformatted" and "binary" I/O?
Thanks,
Arturo di Gioia
