[GRASS-user] Running v.surf.tps

   I have an instance of v.surf.tps running on a host with an
8-core/16-thread CPU. The Gkrellm system monitor shows 0% compound CPU usage
and about 2G of memory being used, but the disk activity is very high. This
suggests a lot of disk reads and writes instead of using more memory (the
host has 32G total).

   Are these numbers due to multithreading using all threads, but each one
working off the disk rather than RAM?

   I would like to understand so I can speed analyses by maximizing the
hardware capabilities.
