I have over 150 machines that have not got any tasks today and they are getting tasks from Einstein which has a resource of 0.

Any idea why polling less than 303 seconds does not return the normal error about the request being too recent?


Um.. How do you fit all 150 machines at home? Or did you hijack a corporate server farm? How do you finance the powerbill for those 150 machines?

With a moderate assumption of 150W/machine would mean 22,5kW. At a 0,1€/kWh this would cost you 2,25€/hour -> 2,25€*24 = 54€/day -> 365* 54€/day = 19710€/year to run.

With the power youre spending you could trade in your car for a new one every year.

IIRC he owns a server farm. Which he runs projects on when he doesn't have it leased out.

LOL
Yes these are servers at my work that I can use when we are not doing their "real work". I use them in between test cycles. They are HP c7000 Blade Chassis mounted 4 to a rack and the company was actually experimenting with special cooling systems for the equipment racks that the company was going to sell. There are 3 160KW cooling systems in our lab. The cooling system alone could handle several large homes. The company has since abandoned the cooling project.

I'm working on a project that's tooling up to use carbon-dioxide mixed-phase cooling in its system (particle detectors, not CPUs) but I'd love to commercialise it for processor cooling. Probably too expensive for home computing (a hefty compressor is needed to liquify the CO2) but maybe for server farms?

Greetings,

Dang near 5,000,000 WUs between MB and AstroPulse and my BOINC client event log says project has no new tasks?

What gives?

Keep on BOINCing...! :)

Same thing happening to me. I took a break from crunching over the holidays so my hoppers are empty. Now that we're back up again, I can't get any work? That is disappointing.

Just got 24 CPU tasks when I want GPU, when I looked all 24 are VLARS!!!

It appears that there are so many hosts with empty caches all trying to get tasks at the same time that the system is having troubles getting the tasks delivered. Tasks are coming out very slowly. I have gotten a few hundred between all my hosts today. We just need to remain patient while the servers get caught up.

Enjoy a mug of your favorite beverage and have a happy new year.

The cricket graph is well short of max,
somthing iz still broken.
the work cant get to the pipe to go slowly through it.
There shurly cant be that many VLARs not going to GPUs ??!!
I would realy like to get back to crunching VLARs on my ATI GPU but Eric an Co wont let me, [/whinge]

Yep.
If there are that many WUs ready to send, and everything was working as it should then the traffic should be maxed out. It's not, and most requests for work result in the No tasks available message.


EDIT- one of my systems just scored 38 WUs for the GPU. They're not shorties, so it should last for a few hours before they're all done.

I just got 44 GPU work units - unfortunately all shorties.

if there really are 5,000,000 + workunits ready to send ... it will be the great wu flood of 2013 .. head for higher cpu's

I've gotten 26 so far.

Back of the envelope calculations suggest at a rate of 25 units per second could be downloaded, limited due to the pipe's bandwidth. This guesstimate doesn't include any outgoing bandwidth used to for control and status requests.

Now since a significant number of us are using GPUs to help do the heavy lifting, a two day outage would have wiped out most if not all of our 100 unit queue so everybody wants 100 GPU units. That comes out to only filling 900 hosts per hour, best case. So how many active hosts out there crunching with one or more GPUs? 10,000? 20,000? So it's going to take a dozen hours or two to handle demand and that's doesn't include the fact that for the fastest among us could crunch 100 GPU units in under an hour and a good number of us in under a day. It'll take a bit.

And since I've started writing this, I got 41 more.

My GTX 560Ti does roughly 200 WUs per day- if they are all 22min crunching time. Some are longer, most are shorter.
On average it probably does closer to 300WU per day. When it can get them.

It seems that the feeder is having a bit of a problem feeding us.

Still just getting VLARS for the CPU. Never seen this many at once. Nothing for GPU.

Well so far I've gotten all of 67 MB units. 56 GPU, 11 CPU, none VLAR.

I'm now at 99 GPU and 46 CPU.

Like I said before, best super ideal guesstimate is that maybe 900 hosts can be fed 100 units per hour. At the current cricket levels I'll guess maybe 500 hosts per hour.

So how many hosts want GPU units? How many do an Oliver Twist and ask for another full reload in 3/6/12/24 hours?
