I'll take GW_7_291 & GW_7_292 next.

Matrix successfully built @td=116. LA in progress:

[CODE]linear algebra completed 1546945 of 15717685 dimensions (9.8%, ETA 108h50m)

Due to an ever increasing powerbill, I've decided to shut down a 3770k and take a small break from post-processing. This also gives me some time to do rewiring of my Ethernet and clean up the cable mess. I expect to be back in a couple of weeks.

[QUOTE=RichD;401370]I'll take GW_7_291 & GW_7_292 next.[/QUOTE]

Both have their matrices built and should complete with LA at the end of next week.

Can somebody explain the following information on the 14e status page for GW_10_244 and GW_10_247? Little of it makes sense to me.

[code]
# Name Project Type Bits Q range Pushed Unsent Pending Received Relations Est. Pending Rels
8 GW_10_244 GCW SNFS(246) 31 20-100 M 100 % 0 21 4086 94611657 21163743
9 GW_10_247 GCW SNFS(249) 31 20-200 M 100 % 2 1387 995 24365779 251077720
[/code]

Specifically,

10,244:
- With 21 work units pending, how can there possibly be anywhere close to 21M pending relations?
- Why was the special-q range chosen with such a low upper limit? Is there any expectation that 120M or so relations will be enough?

10,247:
- What happened to all the work units? There were 11250 created, and many seem to have disappeared.
- Received has been stuck on 995 for days, though I know that many have been uploaded in that time.
- The pending relations estimate is completely out of whack with the number of pending work units (as with 10,244).

Does some server just need a good kick?

It wouldn't be the first time the status update script took a little nap and needed a little love.
Normally I wouldn't thrust the estimated pending relations, but the gathered raw relations is fairly accurate (if the script works).
However it is not unusual to first push 100M special Q to see how many relations are collected. Based on that the range can be extended to achieve the desired amount.

Okay, well AFAICT none of the currently sieving numbers has had its relation count updated since April 27th. And that's not just the status page; the directories for each number in the nfs_data directory haven't been updated since then either. It looks like *something* needs a little love.
