Are there any tips on making LEAP run more efficiently on multi-processor / multi-core systems? We usually have a multi-processor workstation (say, a Dell T7910) that we use to run various modelling tools.

I noticed that LEAP doesn't run across all the processors/core, and is also slower when running jobs that might be similar in nature / size. Thank you!

When doing least cost optimizations using NEMO, this does take automatically advantage of multiple cores/threads although different solvers seem to be able to take more or less advantage of multi-threading. In general, the "industrial strength" commercial solvers such as CPLEX, GUROBI and XPRESS seem to be better at using multi-threading and this is reflected in their generally far better solution times. You don't need to do anything special to take advantage of these features although you might try tweaking the "number of processors" setting in the Settings: Optimization screen. In general, you can just leave this set to the default of "Let NEMO decide". We have sometimes seen errors being generated if too many processors are used. If you run into errors, just ramp down that setting.

This page also gives tips on optimizing the performance of NEMO including tweaking its use of multi-core CPUs.
