Victor - Does this count the number of users who simply loaded the module? Or 
users who submitted a job using the petsc module (if that’s even tracked?).

The latter. It tracks what modules are loaded when a batch job starts. That’s 
not entirely the same as PETSc actually being used but I guess it’s a pretty 
close proxy.

We track a whole bunch of statistics on batch jobs. (Including hardware 
performance counters on processors, network, file system. One snapshot per 30 
minutes, so it doesn’t interfere too much.) I don’t think we track anything 
about interactive loading of modules.

Btw, almost 1000 unique users over the lifetime of the database, which goes 
back to petsc 3.4, whenever that was.
