Chapel versus Julia 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. fasta source secs mem gz busy cpu load Chapel 1.79 5,308 1391 6.46 99% 88% 87% 88% Julia 2.93 363,468 1182 8.91 74% 79% 78% 73% binary-trees source secs mem gz busy cpu load Chapel 14.54 364,692 488 44.83 100% 79% 74% 56% Julia 20.21 601,980 372 66.53 90% 78% 82% 79% pidigits source secs mem gz busy cpu load Chapel 1.62 6,296 512 1.75 99% 6% 1% 2% Julia 2.06 169,012 506 2.55 99% 6% 13% 6% reverse-complement source secs mem gz busy cpu load Chapel 3.52 1,916,472 755 8.53 98% 48% 49% 48% Julia 3.03 671,492 522 3.54 5% 8% 6% 98% fannkuch-redux source secs mem gz busy cpu load Chapel 15.22 4,392 731 60.73 100% 100% 100% 100% Julia 10.62 190,312 886 39.95 93% 92% 99% 93% spectral-norm source secs mem gz busy cpu load Chapel 4.16 5,456 310 16.29 99% 98% 97% 96% Julia 2.79 179,764 521 9.07 75% 75% 76% 99% mandelbrot source secs mem gz busy cpu load Chapel 5.54 36,240 588 21.91 100% 99% 99% 99% Julia 2.64 224,160 619 9.34 86% 98% 85% 85% n-body source secs mem gz busy cpu load Chapel 21.85 5,504 971 22.52 100% 1% 2% 0% Julia 9.57 240,732 1112 10.20 2% 70% 32% 3% k-nucleotide source secs mem gz busy cpu load Chapel 18.77 177,116 989 70.61 100% 91% 91% 94% Julia 7.55 344,020 945 17.36 61% 41% 50% 78% regex-redux source secs mem gz busy cpu load Chapel 7.97 453,364 493 11.36 99% 15% 13% 15% Julia 3.04 439,520 766 5.17 4% 62% 5% 98% Chapel chpl version 1.22.0 Copyright 2020 Hewlett Packard Enterprise Development LP Copyright (c) 2004-2019, Cray Inc.
