Download data sets from MOR Wiki.

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, Chip, FlowMeter, and SteelProfile are stored as plain MatrixMarket .mtx files. FenicsRail is stored as a single .zip archive containing several .mtx files. PenzlFOM is assembled from scratch, i.e., stores no data at all. The remaining data sets are stored as MAT v5 files; which we plan to replace by MAT v7.3 files ... eventually.

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.
