1.3.1 and 1.2.12 performance comparison #142

Open zhaohaifei opened 8 months ago

I want to know whether the overall performance of version 1.3.1 has improved or decreased compared to 1.2.12. We prepare to upgrade from 1.2.12 to 1.3.1.

Hello,

There should be no regressions between version increments. The 1.2.12 is an older version of VkFFT and since then there have been many algorithmic improvements, especially for primes >5. Also, the 1.3 versions had way more testing done on them so they should be more stable than early 1.2. And in case there are any regressions that you notice - I will be happy to fix them.

Best regards, Dmitrii
