where `N` is the number of parallel processes. On discover head nodes, this should only be as high as 2 due to limits on the head nodes. On a compute node, you can set `N` has high as you like, though 8-12 is about the limit of parallelism in our model's make system.
where `N` is the number of parallel processes. On discover head nodes, this should only be as high as 2 due to limits on the head nodes. On a compute node, you can set `N` from 6 to 10 which is about the limit of useful parallelism in our model's make system.

***NOTE***: Do *not* use `make -j install` with GEOSadas. The GEOSadas has a *lot* of parallelism at the beginning and the build system will gladly build as much as it can at the same time. However, the license server for the Intel compiler on discover will quickly lock up as each process accesses it, and will "break" the Intel compiler for all other users.
