Last years Thumper outage lasted about 12-14 days including catchup time.

It started on 1st May 2007 and ended around 12 May 2007.

That was an exceptional outage. The most recent one was ~ 42 hours i.e. less than 2 days.

BOINC is designed to cope with whole project outages. OK some of you want to run SETI only. That is your choice. I have SETI as my highest resourece share, but I also manage to run 8 other projects (including SETI Beta), it should be 9 but I just joined orbit@home and they don't currently have any WU's.

I run a 2.5 to 3 day cache across all projects which usually gives me about 2 - 5 SETI WU's in reserve. Recent SETI WU crunch times have varied between 2 to 6.5 hours. It works for me.

If you are running SETI only, I don't see any good reason to go beyond 5 days cache, 3 days should be enough to cover most normal outages.

Even if you got a whole bunch of -9 overflows, you would be very unlucky to get more than 10 in a row.

I think some people run the big caches because they see that option and just "go for the biggest". If the sofware allowed it they would probably cache 21 or 30 days worth of WU's!

Just my thoughts, btw this thread seems to have gone a bit off topic.

Lets just hope NEZ's timings coincide with a slitter problem, if his machines decide to request 200,000 thousand or so units at once then we could see a lot of issues., His RAC has tripled since I joined the project, so good knows what new machines he has managed to get working on Boinc. The guys are still having splitter problems now, if this spreads then we could see another outage.

[quote]I run a 10 day cache, as I have a pretty fast machine. It hurts no-one, as the results are returned pretty darn fast.

You may think you are processing them quickly, but all you are doing is processing WUs that have been already waiting for 10 days on your machine for their number to come up.

Since I have a pending file nearly three times as much as my machines can process in a day, I'd say I'm getting stuff done faster than the rest of the quorum, in most cases. The 10 day cache isn't holding anyone up.

You still return your WUs 10 days later than you got them, and your machine's speed is totally irrelevant.

See above.

I hate to sound rude, because this isn't meant to be rude.
I think you're wide of the mark.
However, I shall respect your right to have an opinion.

With seven day deadlines on VHAR units can you actually get a 10 day cache. I wouldn't have thought so.

The last time we looked at the spread of units across the AR spectrum, VHAR's made up 30% of all units, but only ~10% of crunching time. The percentage of VHAR's may have fallen since then but not by much.

With seven day deadlines on VHAR units can you actually get a 10 day cache. I wouldn't have thought so.

Any WUs with a short deadline run as "High Priority" in Boinc, so in effect jump the queue. In theory the cache would stay at 10 days as you are never going to get a run of hundreds of VHAR units.

But as soon as you are in EDF, you are inhibited from downloading more units.
And were you not here at the end of last Dec, until Matt changed the splitter sequence, we had nothing but VHAR's.

I missed that fun as I had a 2 year break from SETI after moving house and selling all my belongings. Only started crunching again in February this year.

Nothing buy VHAR's? How on Earth did the servers/network stand up to that hammering...or didn't they?!

The servers did quite well, you can see on the Yearly Cricket graphs that the average comms rates were at about the highest between ~20th Dec to ~5th Jan.

Matt's tech News post when he first notices the hig traffic volumes and lots of VHAR's is post 696817, Happy 2454466.5! (Jan 02 2008)

Now, does anyone see the logic of why *unnecessarily* large caches are not good?

Please forgive me when I am on holiday next week. I intend to disconnect from the Internet but leave the machine slowly crunching away. I shall need about 8 days of cache. If I was away for 2 weeks then I should want to have 14 days' worth. I suspect there may be a fair amount of that during the summer days and not just people trying to avoid S@H downtime.

Which bit of *unnecessarily* didn't you understand? You don't need my forgiveness!
That's a perfectly valid use of the cache.

No rudeness inferred! I'd die for your right to say I'm wide of the mark, but I also respectfully don't agree with you.
I am looking at the process from a system and resource allocation perspective, instead of limiting my horizons to the extent of my cache!

If everyone behaved this way at the dinner table the cook would be trying to make room for supplies all the time instead of actually doing the cooking, while those that want to take as many cookies as they can in case they're hungry later cause some to go without! ...or something like that.

Just good manners - take what you need when you need it, and keep enough for downtime, not more unless you only have intermittent net access.

Upppssss....!

Uploads don't work. (downloads are working fine, by the moment...).

Well, it seem that all already is working, Satan.

Can you make your uploads without problems?

On Scarecrow's Graphs the Results waiting for validation appears to have flatlined, everything else appears to be turning over nicely.

On Scarecrow's Graphs the Results waiting for validation appears to have flatlined, everything else appears to be turning over nicely.

According to the Data Table it hasn't truly flatlined, but it sure isn't moving very much.

Yeah, i was just looking at that one again as well as the In Progress. I can't remember ever seeing such steady numbers.

Looks like some of the server stats didn't survive the weekly outage. 14 hours since the last update for many of them.

Now it's a flatline.

t-minus 16 hours and.... just sort of laying there limp. :)
