{{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:''' [[EM.Tempo]]'s GPU solver is a CUDA-based engine which is capable of extreme performance (speedup of up to 40x).
===Thread Factor===
The thread factor determines how many threads are effectively used in the computation. It is only relevant for CPU-based solvers. While a thread factor of two or three usually yields the best performance, it is suggested that the user experiment to find the best thread factor for his/her system.
