Not all, depends on the project and application/task. It's up to the project owner and their requirements.

Should I stop creating new pending requests then at some point, because they might not all get validated in the next days? I'm up to over 90 tasks pending validation.

I have over 200 tasks pending. I’d keep on rocking, someone probably has the pending tasks in a bunker.

Yep, just keep going and let the pending climb. Some of us have thousands pending at this point. Some people will drop large bunkers of completed tasks and clear out some pending, but others won't clear out until after the event.

Oh, are all computations done twice in order to validate them? Thanks for telling me 🙂

All of Einstein@Home tasks have wingmen. IE two of the same task sent to two different users hosts.

 

Last I looked I was approaching 30k pending tasks.

The special app on Linux is wicked fast. I can finish a single task in 90 seconds. But now lots of them don't get validated anymore. Are there too many completed tasks coming in?

depends on the nature of that you mean by "don't get validated anymore"

are these errors? (not necessarily normal, what are the specific errors if so)
are these invalids? (normal if you have a 40-series)
are these tasks stuck in pending? (normal during a competition with everyone bunkering)

 

are you using a 40-series GPU? these cards have high invalids. I think it's a driver bug with the 40-series, but that's just a hunch based on what I've seen. havent been able to correlate it with core/mem clocks, OS version, OS type, driver version, app version, or anything else. only 40-series or not 40-series when running gamma ray.

 

an aside,

Petri is a wizard with Nvidia GPU optimization. we have quite a few special apps 😉 when SETI was still running, our special app was like 5x faster than the project provided application. The Gamma ray app was his first OpenCL app attempt. He usually makes CUDA apps. and the early/beta iterations of gamma ray optimization were done without any source code and just man-in-the-middle intercepting the code and changing it on the fly LOL (some code in the binaries are in plain text). But he only makes stuff for Linux. back in the SETI days, several people tried to port his app to Windows but it never worked. something about specific driver features or functions that were in the code that didnt work in windows. don't remember the specifics.

 

there's probably more in the tank for gamma ray optimization. but it's close to being maxed out. it uses every bit of the GPU (full core utilization, full mem bus utilization if you have enough cores/GPU throughput, decently high VRAM use). we could probably squueze a few more % out of it by porting it to CUDA, but that would probably be an intensive code rewrite. Petri doesnt want to put more work into this app because Gamma Ray tasks will ultimately end. likely in less than a year unless the project drums up more work for it. but they have already said it's days were numbered. We actually thought it was going to run out like 6 months ago, but the project added some more. I'm not optimistic that that will happen again though.

Not 40 series related but does ECC help at all with preventing the invalids? I've gotten a few come up as invalid that ran on my A40, but I guess it's more down to why specifically each one is invalid and I'd guess ECC doesn't really have anything to do with it.

I'm not sure. but an A40 is Ampere based and wont have the same invalids issue. seems specific to Ada. Enabling ECC is very likely to slow the task down a lot though, since they are so reliant on memory speed and bandwidth.

 

~4-5% invalids is normal. 40-series cards are seeing 10-20%.

 

invalids can happen for a lot of reasons. some apps just don't validate well with each other when they use very different math libraries. it's pretty normal that like-apps will validate with each other better than with other apps. but as long as they are relatively low, it's not a problem for the project. invalids get resent to a new user until one of them validates. it only sucks for the user who got the invalid and no points

Thanks, had a look at most of my invalids and they were different app versions or based on run time the optimized one.

 

I'd like to try out the optimized version but I had to assign the GPU back to app service that uses it, just does video transcoding of very long lecture recordings. Bit of a waste of an A40 really.

You mean you guys aren't using your Ti 83 Plus calculators to do these tasks faster?

Too fancy, still using punch cards and post mail to send them off to get run and returned. Real pain if one of the cards isn't punched correctly.

@SkillzTA Oh I gave up on running E@H on CPU btw. Multiple different CPU models and they were all going to take over a day to complete per task. I tried and failed.

IIRC, you should only run gamma ray CPU tasks also. the gravitational wave tasks can need like 3+GB per task.

 

but really, CPU isnt worth it on Einstein, unless that's all you have. no use contributing CPU power to a project with both GPU and CPU tasks on the same subproject. just put your GPUs there, then use the CPUs for a CPU-only project. It's a much better use of the resources.

How do you think Einstein@home is sending me my tasks? My internet is too slow.

Thanks, I'll try and remember if I ever have to try it again.
