Description

Hello,
contrary to the documentation in https://github.com/LLNL/SAMRAI/blob/621f64890ac8504fd904b1cea52398e7b7743a7e/source/SAMRAI/appu/VisItDataWriter.h#L94, and https://github.com/LLNL/SAMRAI/blob/621f64890ac8504fd904b1cea52398e7b7743a7e/source/SAMRAI/appu/VisItDataWriter.h#L201, there is an assertion in https://github.com/LLNL/SAMRAI/blob/621f64890ac8504fd904b1cea52398e7b7743a7e/source/SAMRAI/appu/VisItDataWriter.C#L121
that prevents the use of multiple procs per file.

This is quite a problem in simulations with a lot of procs as it may exhaust INodes on the storage.
Is it intentional or just a typo?

Thanks
