Am I doing something wrong? I have received credit in the past, so I know I can do it. ID: 1452 · Rating: 0 · rate: / Reply Quote

I don't think it's you, Ross; I'm seeing the same errors on two different systems. The one with more memory is happily working on 16e tasks, but 14e produces "Computation error" immediately for both. And looking at the statistics at http://escatter11.fullerton.edu/nfs/crunching.php, it appears that no work units at all have been successfully processed for GC_2_802, so that's probably the culprit.

I have two other computers (Ubuntu 12.04, Mint 17) and they seem to be doing OK. I have Windows 7 Professional 32 bit (fully updated) with 4 GB RAM.

Last modified: 13 Dec 2014, 20:06:34 UTC c0 should be +1 /sigh/ Also if it is to be restarted anyway, a better poly would be with c6: 401, c0: 2 and double Y0, double skew ID: 1459 · Rating: 0 · rate: / Reply Quote

Second, I'm not even sure what Batalov meant or how to do it. OTOH, the more recent tasks I've been getting haven't been the ones which have the immediate failure, so maybe I should just keep calm and NFS on? I have noticed that I aborted some 13 tasks early this morning, as one of my machines had not yet started them but they were beyond the deadline. Still, that machine seems to be doing quite well with the new tasks it's been given. So I guess I'll keep calm. (grin) Ross ID: 1460 · Rating: 0 · rate: / Reply Quote

Right now I don't have access to the database to be willing to make the changes, abort current wus and start new batch. Just keep calm, Greg the admin is very busy and I already contacted Lionel who has access to 14e database. Carlos ID: 1461 · Rating: 0 · rate: / Reply Quote
