They may seem more-like a fair comparison to you. binary-trees source secs mem gz busy cpu load Chapel 14.54 364,692 488 44.83 100% 79% 74% 56% Go 25.19 397,116 1007 86.01 88% 86% 84% 83% pidigits source secs mem gz busy cpu load Chapel 1.62 6,296 512 1.75 99% 6% 1% 2% Go 2.04 8,724 603 2.36 20% 32% 33% 31% fasta source secs mem gz busy cpu load Chapel 1.79 5,308 1391 6.46 99% 88% 87% 88% Go 2.11 4,228 1358 5.66 69% 65% 64% 70% reverse-complement source secs mem gz busy cpu load Chapel 3.52 1,916,472 755 8.53 98% 48% 49% 48% Go 3.73 826,488 611 4.10 88% 6% 2% 14% mandelbrot source secs mem gz busy cpu load Chapel 5.54 36,240 588 21.91 100% 99% 99% 99% Go 5.55 30,300 894 22.11 99% 99% 99% 100% spectral-norm source secs mem gz busy cpu load Chapel 4.16 5,456 310 16.29 99% 98% 97% 96% Go 4.12 2,704 548 15.93 96% 98% 97% 96% fannkuch-redux source secs mem gz busy cpu load Chapel 15.22 4,392 731 60.73 100% 100% 100% 100% Go 14.93 3,484 969 59.67 100% 100% 100% 100% n-body source secs mem gz busy cpu load Chapel 21.85 5,504 971 22.52 100% 1% 2% 0% Go 21.26 1,888 1310 22.28 3% 0% 100% 2% regex-redux source secs mem gz busy cpu load Chapel 7.97 453,364 493 11.36 99% 15% 13% 15% Go 7.21 326,552 810 10.19 22% 18% 87% 14% k-nucleotide source secs mem gz busy cpu load Chapel 18.77 177,116 989 70.61 100% 91% 91% 94% Go 12.67 150,584 1722 47.44 95% 90% 93% 96% Chapel chpl version 1.22.0 Copyright 2020 Hewlett Packard Enterprise Development LP Copyright (c) 2004-2019, Cray Inc.
