[[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.
{{note|Accuracy-critical computations, such as Farfield calculation, are still performed in double-precision.}}
{{note|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.
*'''GPU Solver:'''
