What was your general impression of 34-bit vs 33-bit? Will the extra bit allow slightly larger jobs to be run as I'd hoped?

[QUOTE=frmky;591636]2,2174M is in LA, so here's one more data point. Running on [B]eight[/B] NVLink-connected V100's,
It'll take a bit longer due to queue logistics, but hopefully it'll be done within the week.[/QUOTE]

How many relations did you collect? Was the unique ratio better than 2,2174L's? The matrices came out pretty similar in size, so a comparison of relations counts (raw and unique) gives a nice 33 vs 34 data point.

For 2,2174L we sieved from 20M - 6B, and collected 1.36B relations. This gave 734M uniques, so about 46% duplicates.

For 2,2174M we sieved from 20M - 4B, and collected 2.19B relations. This gave 1.29B uniques, so about 41% duplicates. However, we sieved a considerably narrower range of q, and it was overall much faster.

[offtopic] I changed the thread title. The old one made me [URL="https://en.wikipedia.org/wiki/Romanian_profanity"]nostalgic[/URL] every time someone posted in it... The new title is easier to search too, as the thread contains a lot of useful info... [/offtopic]
