Available Data Sets

The following list associates the subtypes of MORWiki.Benchmark to their MOR Wiki entries. If a certain benchmark has not been added, yet, please open an issue.

• SteelProfile: Oberwolfach Steel Profile and ALBERTA Rail 371
• FenicsRail: FEniCS Rail

Installation

import Pkg
Pkg.add("MORWiki")

Getting Started

A picture code snippet is worth a thousand words:

using MORWiki: assemble, SteelProfile
using UnPack

@unpack E, A, B, C = assemble(SteelProfile(1357))

Should you get a benchmark's variant wrong, the error message should guide you along:

julia> SteelProfile(1000)
ERROR: ArgumentError: Unsupported dimension 1000. Did you mean 1357?
[...]

For more granular control, the data sets are available via DataDeps.jl using their MOR Wiki benchmark IDs:

using MORWiki, DataDeps

datadep"steelProfile_n1357m7q6"

FAQ

• What triggers a download?

  A data set is downloaded when it is references via its datadep"" identifier. This happens only when calling assemble(...); creating SteelProfile(1357) or any other MORWiki.Benchmark does not download any data.

• Where are the data sets stored?

  This is handled purely by DataDeps.jl. As of version 0.7.13, data is by default stored at ~/.julia/scratchspaces/124859b0-ceae-595e-8997-d05f6a7a8dfe/datadeps/. Please refer to DataDeps.jl's end-user documentation for further information.

• How are the data sets being stored?

  Currently, only SteelProfile is stored as plain MatrixMarket .mtx files. All other data sets are stored as a single .zip archive containing several .mtx files.

Warning

The following releases have been data-breaking: none

Should you upgrade MORWiki.jl to (or skipping) one of the versions listed above, consult the CHANGELOG to see which data sets must be deleted and re-downloaded. Be assured that such changes will always be marked as a breaking release according to the Pkg.jl documentation. Of course, not every API-breaking release is also data-breaking.
