Server Trouble

Hello Tom,
Still the same problems trying to get work!

I get the feeling that the server thinks there are 17M jobs ready to send out, so it doesn't make more jobs. However, I cancelled all of those jobs in order to try to clear the validation backlog. I'm not sure where the jobs are stuck, but I will turn things off and reset their transition times, and see if that clears them.

Hello Tom,
Validation Pending increasing quickly now @10000

Workunits waiting for validation 233606
For the system at the moment. This has been growing since yesterday, and it should be looked into as to why this is happening.

Pretty sure the validator crashed.

Just had WU’s validated, it may be a bit slow but I think it’s working.

On the server status page everything is running .

Can't be running properly no work being given.

Oh please be patient, the server is powered by hamsters.

I believe Tom was working on something and called it a night last night to look into it more today, something to do with trying to flush stuck tasks or something. https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4863&postid=72565#72565 I haven't had work units for about a day now, maybe just under a day. My computer had been working on the Separation tasks though. But either way, hopefully we'll get more work units today at some point or a status update.

It looks like the backlog has mostly cleared up and there is a pool of ~15k separation WUs that are ready to be sent out. Are people still struggling to get work?

Thanks Tom. Yes, for me at least they don't seem to be downloading with BOINC, just deferred a few times when requesting an update for the project in the UI.

Yes, I only do Separation and I find it difficult to get work without pinging the scheduler every 5 minutes to get a few here and there with an update.

---

Similarly for me, though I haven't gotten any work units in the past day or so, but before then would often have to request an update to get a batch of them.

...

Edit: Just got some now after an update request. Thanks.

Edit 2: And it's run dry for me again. Well, a handful today so far at least.

@Tom asked:

.... Are people still struggling to get work?

YES - after a 24 hour break, I started my rigs - and not getting any Separation work.

What is the feeder sleep setting?

I cannot get any tasks

Regarding your five Radeon R9 280X cards, how do you like them? Sounds like you are pretty well pleased.

Love them. One of them I play games on.

What is the per card power draw under MW@Home?

Less than the 250W TDP, I think about 180W.

And how many WUs can you do per card in an hour?

If I run enough at once on the card to make the % usage sit in the high 90s (this depends on processor speed), they do one per 38 seconds per card.

I have 2 PCIe 16 slots available, and am thinking of replacing a quadro P1000(6 WU per hour) with one of these,

280X are way faster than that, that's 45Gflops on double precision (what MW uses), the 280X is 1024, 23 times faster! Only 3 times faster for single precision (every other project).

and populating the second slot also.

You can run huge numbers of cards off 1 slot. Get some risers designed for bitcoin, thus: https://www.ebay.co.uk/itm/363533746057 - that one is a single, but you can get ones with 4 sockets in one. And you can daisychain them - I tested a 4-way with a 4-way plugged into it, so 16 cards off one slot. And the slot can be 1x.

Another option is to go new, with Radeon 6600 XTs. But the way you went sounds like more bang for the buck.

Work out the electricity cost also.

My power supply is 750W, so hopefully wont need to upgrade that.

Is it a good 750W, or a Chinese 750W? Cheap supplies (eg. CIT) don't like going over 50% power. Good supplies (eg. Corsair) will do the rated power. I run most of mine of a 1kW 12V LED lighting power supply. A lot cheaper than PC power supplies.

CPU is a Ryzen 9 3900x.

Snap! (Almost) - I have a Ryzen 9 3900XT. Wonderful CPU, except AMD's virtualisation implementation sux - if you run anything with Virtualbox (eg. LHC, Rosetta, Cosmology), then the interface gets sluggish, but if it's just for Boinc and you're not trying to interact with it, then it's fine. Otherwise, limit the number of VB tasks.

ps. we have a cockatiel like your 2 new ones. He'll be 20 this year, and active as all get out. His name is Cheeks, and he's an alcoholic. Will post a picture when i figure out how!

Alcoholic!? I've never tried giving mine alcohol, I do homebrew at 23% alcohol (don't tell the taxman) and consume 5 times the recommended daily allowance, which is apparently perfectly fine. 4 times the RDA is apparently the same as being T-Total - less than that and you're actually healthier. My 16 parrots are all chocaholics though, it's apparently bad for them, but they manage to steal some sometimes.

power supply is a Seasonic Focus GM-750W 80+ Gold. It's an "A tier' unit. should be good for the extra load.

I think I'll be fine with the electricity costs.

regarding the risers, probably wont do that in this case, but have been toying with the idea of a mining rig type setup, but just for MW@H. That would probably kick some serious butt, but will need to wait and see if the project stabilizes regarding the recent spate of down times. I have only been here since November 2021, but have seen several major down times. Eventually it will get sorted out to the good,

Curious, what's the reason for Separation only?

I generally only do gpu tasks for projects that offer both. My cpus are working on Universe, TN-Grid and yoyo.
Gpus are much more efficient than cpus.
My gpus do Milkyway, Einstein and GPUGrid.
