Advanced molecular dynamics simulations for GPUs 2.19 (cuda1121) is my first WU running fine.

The GPUGrid server let me crunching the WU for 5 days.
I need more days to close the crunch.
I'm at 75% after 3.5 days and the deadline is 2022-03-07 06:21 UTC.

I’m afraid to lose the time I donate to your projects.

Please give more time to finish the WU

I also have processed this kind of tasks on a GTX 750 Ti GPU.
If I want them to finish inside their 5 days deadline, I have to heavily overclock the GPU...
But exceeding the deadline doesn't necessarily mean that you won't receive any credits for your job: Deadline is in fact "extended" in a variable number of hours, or even days. In some way, it's like a bet.
It depends on the computer that catches your re-sent task after its deadline.
If the task reaches a high-end computer, the minimum deadline extension you might expect is about 7 hours for a RTX 3080 Ti, for example.
If the other computer sends a valid result for that task before you, your task won't receive any reward (Ops!).
But if your task is finished and reported first, you'll get your credits (Horey!)... and the second computer will lose any bonus (Oooops!! :-)

I’m looking forward and I hope to receive the automatic deadline extension.

Thank you for your suggestion about GPU overclocking. I’ll read the post but I’m not interested to do any overclock.

If I cannot finish the crunch by 5 days, I’ll do by 7 or 10 days ( 😊 ).

I hope the project administrators could give the volunteers enough flexibility.

Really interesting and wacky the final race lap. At my deadline, a new WU is assigned to another volunteer but I’m not out of the game 😊. I’ll can earn the whole loot if I’m the first to cross the finish line

Thanks for your time.

Invest in a faster GPU if you want to reliably contribute here. 750ti is very low power compared to more modern offerings and the project as a whole is trending towards more and more difficult tasks. It’s unreasonable to expect a project to support certain GPUs forever, at some point you just need to upgrade the hardware.

Soon the 750ti will be essentially unsupported anyway. The new acemd4 application will be requiring greater than 2GB (up to 3GB) GPU memory and your 750Ti won’t have enough to crunch any tasks.

If you want to keep using your 750Ti, it would be best to use it on a project that has much smaller tasks. Like milkyway, einstein (gamma ray only), or world community grid Open Pandemics Covid-19 (when they come back in a few months). But in my opinion, cards in the range of 750Ti or slower are not suitable for GPUGRID anymore.

As Ian suggested you will need to move to newer and more powerful hardware.

The project is moving to the cutting edge of machine learning/artificial intelligence with both cpu and gpu necessary to compute the tasks.

This is going to require fast cpus and gpus with LOTS of memory. Just the nature of machine learning I'm afraid.

I was getting 3-4 hour tasks for a few days and things were going great. Then I got one that was running for about 17 hours and was only about 20% done, which I aborted. Is there a way to only request smaller tasks?

Thanks,
Neal

Not at this time. Maybe later the admins will get back to previous method of segregating "long" and "short" tasks.

The current "short" ones are only test tasks and not typical of what the project normally sends for research data.

What is considered normal is 12-14 hour tasks on modern, high-end hardware. Middle to low end hardware will be pushing up against the 5 day deadline.

Thanks. My hardware is probably not up to this project in that case.

What kind of gpu card is good? I found a list in the forum, but it looks to be several years old. I would like one that's energy efficient and has a low overall power consumption.

anything from the Turing or Ampere generation will be the most energy efficient in terms of work done per watt.

GTX 16 series
RTX 20 series
RTX 30 series

low power consumption is relative. what is "low" to you? what's the max TDP you are comfortable with? do you have an available 8-pin PCIe/VGA power connection from your PSU if needed?

Thanks for your help.

Ideally it would be bus powered. My current card is 70 or 75 watts, and that is great.

Only bus powered limits you to cards not really suitable for this project.
I suggest you try using your gpu on other projects with not as much need for modern hardware.

Hypothetically, if you were going to get a GPU just to do GPUGRID, which one would you get?

As Ian mentioned any from this list of candidates and what you can afford.

GTX 16 series
RTX 20 series
RTX 30 series

I've been purchasing new RTX 30 series cards at MSRP lately. They are still expensive even at MSRP.

Maybe a used one from the RTX 20 series if you can find one for an decent price.

Thanks for your detailed answer.

I'm pretty new to gpu compute. My main card right now is a Quadro M2000 [1] that I picked up used for $100. I've decided to see what I can do with this before spending more money. I'm getting quite good results on Einstein@Home and the Binary Pulsar Search application. I've picked up ~790,000 points in about 5 days [2].

I'd rather be curing diseases than looking for pulsars, because I think curing diseases is more important. That may have to wait until World Community Grid comes back and I can try Open Pandemics.

My GTX 1060 is faster than my GTX 1650 This waa explained to me in a SETI@home message board becaus the GTX 1650, with 4 GB Video RAM, has a 128 bit bus while the GTX 1060, with 3 GB Video RAM, has a 195 bit bus.

The GTX 1660 Ti definitely looks good. The GTX 1660 Super looks even slightly better according to the specs. Is that right?

No. The GTX Super has less CUDA cores than the Ti. (Ti 1536) (Super 1408)

The GTX 1660 Super specs say that it has 14 Gbps of memory bandwidth and the Ti has 12 Gbps. Tullio's post makes it sound like memory speed may be a bottleneck.

If the CUDA core count was the same I would say that yes the Super would be faster because of the higher clocked memory.

But CUDA core count comes first in determining the speed of the applications here at GPUGrid.

Second would be the card bandwidth and as long as you run a card in X8 or faster is marginal difference.
