OH,
So it's a server problem?

*panic off*


Rule #1: Only panic if it's a hardware problem.

Rule #2: It's always a hardware problem.

But I work in the remote administration of network printers.
That's software controlling hardware.......

According to the server status page the two download servers are back up:
download server 1 bane Running
download server 2 vader Running
Nothing coming through yet but then am I surprised? I guess it shows that Matt is up early as promised, poor guy, and getting on with a seemingly endless task!

Well I have one machine out of work now. Its a P4 @ 3Ghz (usually does orbit and seti). I will have to give it a bit of extra cache :-)

One of my quaddies has decided einstein is the way to go and the other two quaddies have a bit of seti stuff left before they also become dedicated einstein crunchers. Ah what fun we have.

I must have got lucky as all my Quads managed to snatch work in the brief time the servers have been back up. I do have a 10 day cache though, so little danger of running out of work (I would have hoped!).

Considering the outages We're having and have had in the past, I have a 2.5 day cache, At one time someone said that was excessive, I'm glad I ignored that and left It there now. The poor server, dying before Its time, have to put It to sleep today so It'll be out of Its misery and then We should be able to rest easier. :D

I did wonder if 10days was excessive, but as the machines are dedicated crunchers and I only crunch for SETI they can keep plodding on while things are broken. My Internet connection has been down for several days in the past, so again I'll be able to ride out that if it happens again.

Well my 2.5 day cache (I did bump it to 3 but I dont think it grabbed any as that was the start of the downtime) had left both PC's with less than 3hrs work when they started grabbin WU's a few minutes ago - yay!

It's relative. If you crunch only one project, then something around 3 days is probably good. I think using the "extra days" setting to control the cache works best.

If you crunch more than one project (at different sites, SETI and SETI beta don't count as different), then you can run with a really short cache, and let the long-term debt handle it.

If your cache size is longer than the shortest deadline on a project, that can be an issue.

10 days is just silly and forces everyone dependent on them to wait for credit, and the server cannot expire them to make room for more work while they are still in circulation, so my advice to everyone:

Please set your caches to the MINIMUM you actually NEED.

2 days should be enough for everyone to cope even with this unusual and extended outage.

Mine is set for 3 days and a few months ago I ran out.

Yeah, maybe i'am in trouble, cause several WU's, deadlined @ 17!; 18; 19 & 20
april, how do i get those 17 april WU's to upload now?

Can this be done manually, they are not in the 'SEND' part off BOINC manager.
They are 'ready to report' ?!

While I am still waiting for credit from over a Month ago I don't see that 10 days ago is a particularly big problem for anyone. The cache still turns around very quickly compared to say someone that has a slower machine on only a part of the day whilst they are working etc. 2 Days is not enough in this instance as 2 of my Optiplex (3Ghz) machines (which did have a 2 day cache) have run out of work already - as it happens I had made a decision yesterday to retire them when they ran out of work, so it has just happened sooner than I anticipated.

Besides, whether you get the credit NOW or in 2 weeks time, your RAC will still work out the same as an average over x amount of time.

My PCs are set at 2.5 days of cache each and that is where I'm comfortable at since I don't do anything outside of Seti anymore.

I had it set to 15 days, so go on have a moan at me, yet I've almost cleared it n 12.

2 days is fine if you want to run other projects, at the present moment I do not wish to do so. It makes no difference I am still getting pending credits from the last 15 day set of tasks I cached. I have reduced this to 8 days. But it is not getting any lower than that.

I don't see a problem running a large cache if people want to, if it was such a terrible thing, the settings would not allow it. Personally I run 1 - 2 days, depending on the host, a couple of mine ran out of work in the last day, no big deal, I just turned them off to save some cash.

Look. You can all do what you like, but I'm saying there is no need to be so anally retentive over workunits. I ran out too, but did abc for a few hours and now have new seti WUs, it's no big deal!

If everyone had 10 day caches, there would be (10 x WU per day x number of users) workunits in circulation and they would need to be stored on disk and kept track of in the database, so those with large caches are actually contributing to the problems you are so desperately trying to avoid!

If everyone had 0-2 day caches, then the Tuesday downtime would be shorter and the servers and storage space wouldn't be so stressed, and everyone can have shorter pending lists and go home earlier... There are about 3 million WUs in circulation, each taking up about a third of a megabyte - go figure!

It just makes sense to act responsibly to help smooth things along, that's all.

As for ridiculously long deadlines - there needs to be a method of cancelling orphaned WUs if someone bites of more than they can chew and throws up...

You seemed to miss many peoples point...We are on the Seti board because a lot of us feel loyal to Seti and do not run other projects...When Seti goes away unless some new project comes along I am as passionate about I will probably just turn things off again like I did when Boinc took over. Maybe finding ABC's is important to you but not worth my electric bill....

Yep I totally agree. If S@H disappears thats it for me, I wont crunch any of the other prijects as none really catch my interest and are not worth the power bill to me. I have a 4 day cache and that should get me through all but the most severe WU drought.

If people cant wait 4 days for me to crunch, then bad luck for them. About 70% of my WU's seem to go into pending for a day or so anyway, so in real terms a few people will have to wait the extra day for me to crunch, but most wont even be slightly affected at all.
