Chapel versus Intel Fortran 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% Intel Fortran 3.35 8 1351 3.45 0% 0% 100% 3% reverse-complement source secs mem gz busy cpu load Chapel 3.52 1,916,472 755 8.53 98% 48% 49% 48% Intel Fortran 4.94 985,376 1019 5.28 95% 3% 3% 6% pidigits source secs mem gz busy cpu load Chapel 1.62 6,296 512 1.75 99% 6% 1% 2% Intel Fortran 1.74 4,012 981 1.79 0% 100% 0% 2% fannkuch-redux source secs mem gz busy cpu load Chapel 15.22 4,392 731 60.73 100% 100% 100% 100% Intel Fortran 12.58 11,036 1158 50.21 100% 100% 100% 100% mandelbrot source secs mem gz busy cpu load Chapel 5.54 36,240 588 21.91 100% 99% 99% 99% Intel Fortran 3.69 36,232 957 14.68 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% Intel Fortran 2.07 1,764 638 8.29 100% 100% 100% 100% n-body source secs mem gz busy cpu load Chapel 21.85 5,504 971 22.52 100% 1% 2% 0% Intel Fortran 8.29 8 1524 8.61 1% 0% 2% 100% binary-trees source secs mem gz busy cpu load Chapel 14.54 364,692 488 44.83 100% 79% 74% 56% Intel Fortran 5.48 114,064 1148 16.65 65% 79% 89% 71% regex-redux source secs mem gz busy cpu load Chapel 7.97 453,364 493 11.36 99% 15% 13% 15% Intel Fortran 1.73 175,952 2225 4.90 67% 62% 61% 94% k-nucleotide source secs mem gz busy cpu load Chapel 18.77 177,116 989 70.61 100% 91% 91% 94% Intel Fortran Make Error Chapel chpl version 1.22.0 Copyright 2020 Hewlett Packard Enterprise Development LP Copyright (c) 2004-2019, Cray Inc.
