Just a tiny comment on this: It might be easier for the LAPACK library to use SIMD extensions (SSE2, SSE3, AVX) if we use DTRTRS. So we need to benchmark with relevant matrix sizes to see which strategy is the better. One is better for SIMD, the other is better for cache. The best way to time this is to put performance timers inside the Cython code: - Windows: QueryPerformanceCounter - Mac OS X: mach_absolute_time - Linux: clock_gettime with CLOCK_REALTIME Sturla ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
