Chapel versus Python 3 fastest programs Always look at the source code. These are only the fastest programs. Look at the other programs. They may seem more-like a fair comparison to you. mandelbrot source secs mem gz busy cpu load Chapel 5.54 36,240 588 21.91 100% 99% 99% 99% Python 3 263.87 48,268 688 1,054.07 100% 100% 100% 100% spectral-norm source secs mem gz busy cpu load Chapel 4.16 5,456 310 16.29 99% 98% 97% 96% Python 3 170.10 49,484 417 670.83 99% 98% 98% 99% n-body source secs mem gz busy cpu load Chapel 21.85 5,504 971 22.52 100% 1% 2% 0% Python 3 891.12 8,416 1196 924.03 1% 53% 47% 2% fasta source secs mem gz busy cpu load Chapel 1.79 5,308 1391 6.46 99% 88% 87% 88% Python 3 63.63 841,056 1947 127.80 58% 61% 44% 37% fannkuch-redux source secs mem gz busy cpu load Chapel 15.22 4,392 731 60.73 100% 100% 100% 100% Python 3 494.58 47,432 950 1,956.79 98% 99% 98% 100% binary-trees source secs mem gz busy cpu load Chapel 14.54 364,692 488 44.83 100% 79% 74% 56% Python 3 80.82 448,104 589 288.23 91% 88% 91% 86% reverse-complement source secs mem gz busy cpu load Chapel 3.52 1,916,472 755 8.53 98% 48% 49% 48% Python 3 16.41 1,772,696 434 17.57 1% 78% 28% 0% k-nucleotide source secs mem gz busy cpu load Chapel 18.77 177,116 989 70.61 100% 91% 91% 94% Python 3 72.58 183,484 1967 276.33 95% 95% 94% 97% pidigits source secs mem gz busy cpu load Chapel 1.62 6,296 512 1.75 99% 6% 1% 2% Python 3 2.39 12,200 567 2.55 64% 37% 5% 1% regex-redux source secs mem gz busy cpu load Chapel 7.97 453,364 493 11.36 99% 15% 13% 15% Python 3 2.67 111,864 1403 4.86 87% 30% 29% 35% Chapel chpl version 1.22.0 Copyright 2020 Hewlett Packard Enterprise Development LP Copyright (c) 2004-2019, Cray Inc.
