One way to help to achieve that is to implement it and then write a paper for a technical conference such as IWOMP to demonstrate its advantages.<br><br>As to implementing, there are two aspects to this<br>1) having the compiler understand the new schedule type (and associated syntax in the schedule() clause).<br> This would require changing the compiler itself, not just the runtime.<br>2) having the runtime implement the new schedule when the compiler requests it.<br><br>For prototyping and writing a paper you may be able to bypass the first by using "schedule(runtime)", and then enhancing the runtime to understand your new schedule when it is expressed in the OMP_SCHEDULE envirable. By doing this you avoid the need to make any compiler changes.<br><br>HTH<br><br>-- Jim<br><br>Jim Cownie <james.h.cownie@intel.com><br>SSG/DPD/TCAR (Technical Computing, Analyzers, and Runtimes)<br>Tel: +44 117 9071438<br><br><br>-----Original Message-----<br>From: Openmp-dev [<a href="mailto:openmp-dev-bounces@lists.llvm.org" target="_blank" >mailto:openmp-dev-bounces@lists.llvm.org</a>] On Behalf Of Patrick Buder via Openmp-dev<br>Sent: Monday, May 22, 2017 8:19 AM<br>To: openmp-dev@lists.llvm.org<br>Subject: [Openmp-dev] Extending the openmp schedule clause<br><br>Hello<br><br>Sorry for the blank email earlier.
