(v13) Multi-threading and Harlequin Parallel Pages (HPP)

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

Multi-threading allows the RIP to take advantage of hyper threading and multi-core CPU architectures as well as multiple processors and is designed to improve performance.

These options can be set as a PostScript language file in Sys\HqnOEM. The RIP tries to keep the number of threads set by this control busy, but may temporarily restrict or over-subscribe the number of threads for short periods.

The Harlequin MultiRIP supports the interpretation of one page of a job while the previous page of the same job is being composited and/or rendered in one or more separate threads (Harlequin Parallel Pages) sometimes called “pipelining” or “concurrent pages”. Harlequin Parallel Pages works in combination with multi-threaded compositing and multi-threaded rendering (MTR).

Harlequin Parallel Pages is applied to jobs submitted in all PDLs supported by the RIP.

The use of Harlequin Parallel Pages is protected using a layered option password tied to a specific dongle or permit file or with a Sentinel LDK product key.
