MaxThreads (system param)

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

The /MaxThreads system parameter value determines how many threads the RIP will attempt to use. The RIP will try to keep the number of threads set by this parameter busy, but may temporarily restrict or over-subscribe the number of threads for short periods.

/MaxThreads is an integer. The allowable values are limited by the parameter passed via SwStart() (which comes from the -p parameter in the skintest example) and the maximum number of threads allowed by the current RIP license.

Previously, this could also be an array, but this should not be used. The first element was the max active threads, just set that as the value.

The values returned for /MaxThreads in currentsystemparams show the settings that were actually made after taking the limits set by the RIP skin and the current license for multi-threading limits into account. Note that this doesn't tell you how many threads are actually running at any one time.
