EM.Tempo Acceleration
From Emagtech Wiki
EM.Tempo presents three different options for acceleration. Some details about each of the options are discussed below:
- Single-Precision Solver: EM.Tempo's single-precision solver is a multi-threaded FDTD engine which also takes advantage of modern SIMD facilities (e.g. Intel AVX) found on most processors. It trades a slight reduction in overall accuracy for a relatively large boost in performance.
 |
Accuracy-critical computations, such as Farfield calculation, are still performed in double-precision. |
| |
If EM.Cube determines your system does not have the appropriate SIMD facilities to effectively run the single-precision solver, the double-precision solver will be run automatically. |
- Double-Precision Solver: EM.Tempo's double-precision engine is also multi-threaded, and is slightly more accurate in some cases. It does not take advantage of any available SIMD facilities, which makes it a very portable solver.
