For those of us who crunch Distributed Folding, the last week has been trying to say the least. This most recent protein change over also came with a new 'ticketing' system that pretty much brought everything to a grinding halt. It took several days to get things straightened out, but Howard (the project lead) now thinks they've got it whipped:<br><br><table width="90%" border="1" cellpadding="5" cellspacing="1" bordercolor="#63635A" bgcolor="#E7E7E2" align="center"><tr><td style="font-size: 12px; font-style: italic;">We have resolved the issue that was resulting in 910 errors for a large number of folders. You will have to complete the current run of 250 gens if you are presently receiving a 910 error but after this you will not receive them anymore. If you have nothing buffered, you can just delete filelist.txt to force it to start over at gen. 0 without wasting time on getting to gen 250.<br><br>It appears when we switched to FastCGI (to speed things up) it had a side effect of some peoples' tickets on rare occasion getting the same name (i.e. overwriting the ticket on the server). Thus your result would be lost, and the continuity of your folding movie would be destroyed.<br><br>Thus although it had a few hiccups, we believe the ticketing system is now fully functional and behaving as it was originally engineered. For those of you who have been patient and stuck around while we resolve this, we thank you for your confidence in our abilities For those of you who are gone, well you're not reading this anyways I guess.<br><br>From this point on then, other than as stated above, you should never receive a 910 error again. The only exception is if you upload duplicate data, but in this case you will stop getting 910 once the data you upload is not duplicate again. E.g. if you upload get 3, 4, 5 then delete your ticket before 5 is validated, you will upload 5 again, then 6,7, etc. In this case you will get a 910 error when you upload gen 5 the second time, because it indeed cannot find the previous generation (gen 4) which has already been replaced by gen 5 as the latest gen.<br><br>Hope everything is cleared up now. Elena and I are going to take a long vacation now and catch up on our sleep...</td></tr></table><br><br>Has is really been fixed? Only time will tell, but so far it's looking good from where I sit. My machines have all been uploading properly for the last 12 hours or so. I guess we'll just have to keep our fingers crossed and see. <img src=http://www.free-dc.org/images/news/icon7.gif><br><br>If you took a break from DF until things were worked out (like me), now might be a good time to jump back in. If you'd like to wait another couple of days to make sure everything has 'stabilized', then you might keep an eye on <a href="http://www.free-dc.org/forum/forumdisplay.php?s=&forumid=25" >our team's DF forum</a>. I'm sure any problems that arise will be covered in there...
