Jacques-Henri Jourdan	3d63a106b6	Memprof: optimize random sampling (#9466) ... Instead of using the stdlib logf function for computing logarithms, we use a faster polynomial-based approximation. We use the xoshiro PRNG instead of the Mersenne Twister. xoshiro is simpler and faster. We generate samples by batches so that compilers can vectorize the generation loops using SIMD instructions when possible.	2020-05-25 09:51:15 +02:00
