Hi Miguel,

Normally nproc is how many processors are to be used at any one time by

There was a problem in versions up to dev-767 where nproc was not divided
by the number of search models you supply, so each search model got nproc
processors devoted to it... That should be fixed, so if you are using a
more recent version than that and you get more processors in use than
requested, please let me know.

All the best,
Tom T
