# Judge result # Benchmark Report for */home/runner/work/DitherPunk.jl/DitherPunk.jl* ## Job Properties * Time of benchmarks: - Target: 23 Jun 2022 - 22:42 - Baseline: 23 Jun 2022 - 22:44 * Package commits: - Target: 8d4fb8 - Baseline: a04c48 * Julia commits: - Target: 742b9a - Baseline: 742b9a * Julia command flags: - Target: None - Baseline: None * Environment variables: - Target: None - Baseline: None ## Results A ratio greater than `1.0` denotes a possible regression (marked with :x:), while a ratio less than `1.0` denotes a possible improvement (marked with :white_check_mark:). Only significant results - results that indicate possible regressions or improvements - are shown below (thus, an empty table means that all benchmark results remained invariant between builds). | ID | time ratio | memory ratio | |--------------------------------------------------|------------------------------|---------------| | `["closest color", "binary inplace"]` | 1.19 (5%) :x: | 1.00 (1%) | | `["closest color", "binary new"]` | 1.36 (5%) :x: | 1.00 (1%) | | `["closest color", "per-channel new"]` | 0.86 (5%) :white_check_mark: | 1.00 (1%) | | `["error diffusion", "binary inplace"]` | 1.47 (5%) :x: | 1.00 (1%) | | `["error diffusion", "binary new"]` | 1.20 (5%) :x: | 1.00 (1%) | | `["error diffusion", "color inplace"]` | 1.12 (5%) :x: | 2.06 (1%) :x: | | `["error diffusion", "per-channel inplace"]` | 0.86 (5%) :white_check_mark: | 1.00 (1%) | | `["error diffusion", "per-channel new"]` | 0.89 (5%) :white_check_mark: | 1.00 (1%) | | `["ordered dithering", "binary inplace"]` | 0.87 (5%) :white_check_mark: | 1.00 (1%) | | `["ordered dithering", "color new"]` | 0.94 (5%) :white_check_mark: | 1.00 (1%) | | `["ordered dithering", "per-channel inplace"]` | 0.94 (5%) :white_check_mark: | 1.00 (1%) | | `["threshold dithering", "binary inplace"]` | 1.45 (5%) :x: | 1.00 (1%) | | `["threshold dithering", "binary new"]` | 1.32 (5%) :x: | 1.00 (1%) | | `["threshold dithering", "per-channel inplace"]` | 1.07 (5%) :x: | 1.00 (1%) | | `["threshold dithering", "per-channel new"]` | 0.95 (5%) :white_check_mark: | 1.00 (1%) | ## Benchmark Group List Here's a list of all the benchmark groups executed by this job: - `["closest color"]` - `["error diffusion"]` - `["ordered dithering"]` - `["threshold dithering"]` ## Julia versioninfo ### Target ``` Julia Version 1.7.3 Commit 742b9abb4d (2022-05-06 12:58 UTC) Platform Info: OS: Linux (x86_64-pc-linux-gnu) Ubuntu 20.04.4 LTS uname: Linux 5.13.0-1031-azure #37~20.04.1-Ubuntu SMP Mon Jun 13 22:51:01 UTC 2022 x86_64 x86_64 CPU: Intel(R) Xeon(R) Platinum 8171M CPU @ 2.60GHz: speed user nice sys idle irq #1 2095 MHz 3473 s 2 s 206 s 638 s 0 s #2 2095 MHz 1000 s 1 s 172 s 3154 s 0 s Memory: 6.783607482910156 GB (3546.6171875 MB free) Uptime: 438.4 sec Load Avg: 1.02 0.93 0.48 WORD_SIZE: 64 LIBM: libopenlibm LLVM: libLLVM-12.0.1 (ORCJIT, skylake-avx512) ``` ### Baseline ``` Julia Version 1.7.3 Commit 742b9abb4d (2022-05-06 12:58 UTC) Platform Info: OS: Linux (x86_64-pc-linux-gnu) Ubuntu 20.04.4 LTS uname: Linux 5.13.0-1031-azure #37~20.04.1-Ubuntu SMP Mon Jun 13 22:51:01 UTC 2022 x86_64 x86_64 CPU: Intel(R) Xeon(R) Platinum 8171M CPU @ 2.60GHz: speed user nice sys idle irq #1 2095 MHz 4672 s 2 s 222 s 685 s 0 s #2 2095 MHz 1052 s 1 s 178 s 4353 s 0 s Memory: 6.783607482910156 GB (3677.12109375 MB free) Uptime: 564.65 sec Load Avg: 1.07 0.98 0.56 WORD_SIZE: 64 LIBM: libopenlibm LLVM: libLLVM-12.0.1 (ORCJIT, skylake-avx512) ``` --- # Target result # Benchmark Report for */home/runner/work/DitherPunk.jl/DitherPunk.jl* ## Job Properties * Time of benchmark: 23 Jun 2022 - 22:42 * Package commit: 8d4fb8 * Julia commit: 742b9a * Julia command flags: None * Environment variables: None ## Results Below is a table of this job's results, obtained by running the benchmarks.

@johnnychen94 Looks like the performance increase came from bounds checks being skipped due to the @boundscheck annotation in the inner loop and the outer loop using @inbounds. :/
