Julia versus Chapel fastest performance Always look at the source code. If the fastest programs are hand-written vector instructions, does the host language matter? You might be more interested in the less optimised programs — more seconds, less gz source code. fannkuch-redux source secs mem gz cpu secs Julia #3 8.04 257,756 896 30.44 Julia #2 8.40 261,236 1077 31.34 Chapel #2 8.39 19,772 737 33.40 Julia 38.89 240,772 441 38.98 n-body source secs mem gz cpu secs Chapel #3 3.89 19,648 967 3.90 Julia #8 4.16 272,512 1129 4.25 Chapel #2 5.65 19,648 977 5.65 Julia #4 5.74 252,032 1168 5.83 Julia #3 6.53 254,592 1548 6.62 Julia #2 23.73 301,100 1084 23.86 spectral-norm source secs mem gz cpu secs Chapel #2 0.74 19,648 348 2.89 Julia #4 1.18 248,576 435 3.66 Julia #2 1.35 254,032 377 4.06 Chapel 1.47 19,776 322 5.79 mandelbrot source secs mem gz cpu secs Chapel #3 1.17 37,760 582 4.64 Julia #7 1.40 290,176 629 4.79 Julia #8 1.42 289,152 634 4.87 Julia #3 1.50 315,904 589 5.20 Julia #4 1.97 297,984 583 5.22 Julia #5 1.58 310,400 580 5.59 Julia #6 2.09 290,228 571 5.69 Chapel 6.66 37,632 447 26.42 Julia 26.45 271,104 379 26.53 pidigits source secs mem gz cpu secs Chapel #4 0.75 19,648 515 0.76 Chapel #2 0.75 19,776 423 0.76 Julia #3 1.00 240,640 512 1.13 Julia #2 1.11 247,808 686 1.24 regex-redux source secs mem gz cpu secs Julia #5 1.74 443,844 766 3.05 Julia #4 1.80 448,796 772 3.12 Julia #3 2.26 528,768 630 3.77 Julia 3.86 488,864 414 4.05 Chapel #3 3.74 552,796 503 4.68 Chapel #2 4.53 552,788 498 5.47 fasta source secs mem gz cpu secs Chapel #6 0.79 19,648 1108 0.80 Julia #8 1.10 245,760 1094 1.19 Julia #5 2.41 262,528 957 2.50 Julia #4 2.79 249,088 1053 2.88 Chapel #5 0.95 19,772 1391 3.47 Chapel #3 4.01 19,772 1219 4.02 Julia #7 1.80 439,584 1189 4.51 Julia #6 2.05 475,160 1213 4.78 Julia #3 11.04 247,412 901 11.13 k-nucleotide source secs mem gz cpu secs Julia #8 5.74 441,148 965 13.70 Chapel #4 4.96 192,256 1071 17.07 Chapel #3 5.86 192,256 1040 20.64 Julia #7 8.71 430,084 1379 23.62 Julia 132.23 1,967,872 703 131.10 reverse-complement source secs mem gz cpu secs Julia #8 1.58 1,039,672 531 1.70 Julia #9 1.83 1,038,224 456 1.95 Chapel #8 0.95 1,057,024 1260 2.74 Chapel #3 1.68 1,618,560 709 3.23 Chapel #5 1.79 1,884,928 554 3.30 Julia #2 35.46 1,718,176 464 35.82 binary-trees source secs mem gz cpu secs Chapel #3 8.69 367,360 494 29.22 Julia #2 18.15 644,864 430 35.92 Julia #3 14.34 693,600 640 40.22 Julia #5 Failed Julia #4 Failed Julia julia version 1.10.2 Chapel chpl version 2.0.0 built with LLVM version 17.0.2 Copyright 2020-2024 Hewlett Packard Enterprise Development LP Copyright 2004-2019 Cray Inc. all Julia programs & measurements all Chapel programs & measurements
