When some more tapes get loaded for the splitters to chew on.

AP splits a lot faster than MB does, so this often happens and you have to wait for the MB backlog to catch up.

how long do these "outages" last?

This 1 could probably last a week considering all the tapes that they loaded last week.

Cheers.

Agree it will be longer this time- there's a lot of files to catch up. Guess the staff will look at situation on Friday afternoon and decide whether new files are needed to make it through the weekend.

Is there insufficient data or is the outage the result of administration? Not sure I understand why there is an outage.

It's not an outage.

MB's and AP's are all split from the same files, but you don't get anywhere near as many AP's off a file as you do MB's, though they do need to be a bit more careful with how many new files they load at any 1 time.

But the main thing is that you cannot rely on AP's alone to keep your rig/s full of SETI work.

Cheers.

Not an outage, so I don't know why you are using that term. The same tapes are split into both AP and MB workunits. AP units are larger so there are less of them on any tape. AP is popular right now as many people know they deliver more credit per cpu-second, so they will be snapped up faster.

All of this means that there will always be times when there are no AP units available, and you can choose to process MB or do another project or wait.

APs just split faster than MBs do, and there's only so much storage space on the servers at any given time. You have 50GB files to split from, and then all of the data that comes from that when it gets split, so you end up basically tripling the consumed disk space during the splitting process.

Once both AP and MB have split through a tape, it is unloaded and deleted.

Aside from the high demand for AP lately, you also have to look at what the MB status is. At the time last night/this morning when this thread started, MB was at the "high water" mark so splitting had just about completely stopped. Now that "ready to send" has fallen below a minimum value, splitting has picked back up again.

So it isn't really predictable to say how long it will be until some new tapes get loaded, because the rate at which MB splits fluctuates quite a bit depending on demand from us crunchers. Once the caches of AP run out and rigs start getting more MBs, the demand for those will go up and it will keep the MB splitters going at full steam to try to keep up. Do that for a few days or upwards of a week and the tape list will get pretty short, and then we start all over again.

The circle of life.
