open TELEMAC-MASCARET The mathematically superior suite of solvers

Ah yes, so this is for this stupid reason that we have put PARAL, though there must be somewhere a flag in the system enabling the multiple access to the same file. On Windows the default is that the multiple access is forbidden. Anyway I do not think it is your problem.

Hi Guys,
There is a SHARED specifier to the FORTRAN open statement...
Here is the info from the Inter compiler manual.

Hope this helps... Martin

OPEN: SHARED Specifier
The SHARED specifier indicates that the file is connected for shared access by more than one program executing simultaneously. It takes the following form:

SHARED

On Linux* and Mac OS* X systems, shared access is the default for the Fortran I/O system. On Windows* systems, it is the default if SHARED or compiler option fpscomp general is specified.
