| What the source is | How many | How they were read |
|---|---|---|
| An original release, benchmark or study | 5 | Read in full at their own pages; the study as its PDF, first five pages, read on this machine, with its bibliographic record |
| A project or company describing itself | 6 | Read in full at their own pages |
| A package index or download-statistics service | 4 | The index through its own machine-readable feed; the statistics at their own pages |
| A report of what another party announced or found | 3 | Read in full: a news report of the funding round, a partner's post on the GPU engine, and the study's authors summarising it |
| A practitioner's rule of thumb | 1 | Read in full, and carried as his, with its date |
