Results

Note: If Chrome is your browser, I strongly recommend installing the Wide GitHub extension, which makes the result table easier to read.

Below is a table of this job's results, obtained by running the benchmarks found in JuliaCI/BaseBenchmarks.jl. The values listed in the ID column have the structure [parent_group, child_group, ..., key], and can be used to index into the BaseBenchmarks suite to retrieve the corresponding benchmarks.

The percentages accompanying time and memory values in the below table are noise tolerances. The "true" time/memory value for a given benchmark is expected to fall within this percentage of the reported value.

A ratio greater than 1.0 denotes a possible regression (marked with ❌), while a ratio less than 1.0 denotes a possible improvement (marked with ✅). 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
["linalg","arithmetic",("+","Tridiagonal","Tridiagonal",1024)] 0.78 (45%) 0.75 (1%) ✅
["linalg","arithmetic",("+","Tridiagonal","Tridiagonal",256)] 0.74 (45%) 0.75 (1%) ✅
["linalg","arithmetic",("-","Tridiagonal","Tridiagonal",1024)] 0.78 (45%) 0.75 (1%) ✅
["linalg","arithmetic",("-","Tridiagonal","Tridiagonal",256)] 0.72 (45%) 0.75 (1%) ✅
