About the module
Sample performance improvement:
Speed-up evaluation
The first model includes 19 BiotSavart conductors, and the solving time is over 2 hours and dominated by the coil field calculation (over 85%). The breakdown of the solve process into the main three stages is presented in Figure 4. The overall speed-up achieved using 4 threads, when compared with the singlethread case is 3.21 times.
Multi-core parallel
The number of threads enabled also depends upon the number of multicore licenses available. The licenses enable 22n threads to be used, where n is the number of licenses reserved.
For example, if you have 3 stress licenses and 3 multi-core parallel licenses, then at any one time you could run:
• 3 stress analyses, each using 4 threads
• 3 stress analyses, 1 using 16 threads, 1 using 4 threads and 1 using 1 thread.
• 3 stress analysis, 1 using 64 threads and 2 using 1 thread.
The Multi-core parallel licenses are available in the same configuration as your solver licenses; ie locked or floating on a network.
Control of the feature is via the Opera Manager – simply choose the number of threads to be used for the next solution.
