Garrick's comments are correct. However, in his note, he described a
number of changes made for his local site to support local needs. Some
of these were unrelated to increasing support for job count. Some were
to improve support for a large number of nodes, others were for support
of a large number of classes.
In the latest releases of Maui, only the MMAX_JOB #define must be
modified to increase max job support. In earlier releases which have
the integrated 'MCom' library, both MMAX_JOB and MAX_MJOB must be set.
The Maui docs have been updated to reflect this.
