Project 16921 extremely low ppd

Postby mgetz » Tue Oct 06, 2020 12:39 pm

Normally I wouldn't bring this up, but this set of projects has been abnormally low PPD in comparison to literally every other project. The 169XX series drops down into the 1m PPD range when most other projects regardless of cause range from 2.5m-3m after the recent release of the CUDA core 22 build. Given that the points are supposed to be reflective of the scientific value this to me indicates those projects are low value. I don't mind donating my compute time and power, but I'd rather it be used efficiently particularly right now.

Can you please tell us what the GPU model is? Based on the log above, it seems to be a Nvidia GPU. Also, do you have any historic data to compare the Project's performance on OpenCL VS CUDA?

NVidia RTX2080 in the log; but I've seen this on a 2070 Super on Linux as well (both are TU104 cores). As for non CUDA/OpenCL comparison I do not, I believe this project started at approximately the same time they rolled out the core update. My concern is just how big a disparity it seems to be against other WUs. As the PPD is literally half that of all other observed projects.

The difference between PPD for OpenCL VS CUDA can be anywhere between 15% to 100% which is acceptable since any performance increase (if any) by CUDA is considered as a bonus. The benchmark is done on OpenCL to ensure fair points between different devices. There's a 10% variation within that baseline due to different GPUs and their architecture.

My GTX 1080 Ti on Windows (not dedicated) seems to be within the CUDA range:
Min. Time / Frame : 00:00:23 - 2,053,727.82 PPD
Avg. Time / Frame : 00:00:25 - 1,812,277.78 PPD

WU 16921 (60, 47, 77) seems to replicate the behavior.
Currently running it. So I'd understand that but this is literally less than 1/2 the PPD it's getting with other WUs. On an RTX2080... that makes no sense. I understand there is some points inflation due to COVID, but that wouldn't account for this. I'd expect that to drop down to the 2m PPD range at worst. Particularly since this WU is running in CUDA mode.

I guess what I'm saying here is that there is no way this correlates with the benchmark. Something is seriously wrong with how this WU is running in CUDA mode because it appears to be a net regression.

I see the same on an AMD Vega FE and on 2 different R VII: PPD less than 1/2 on what the cards are getting (on one r vii it's less than 1/3...) for other projects.

1080Ti and Titan Xp (under Linux) are showing "normal" PPD.

The problem appear for all 169XX Working units. It seems that some of theses projects are on the low side as number of atoms goes, and the GPU card are not fully used for these.

elsewhere, Bruce said:
On the other hand small proteins have very few calculations which can be done in parallel and all the serial portions still have to be performed. Your 2060 is great at processing large proteins and not so good working on small proteins.
(about 16904) Is it the case for all 169XX? I do not know.

To which point this apply for 16921, I do not know, but I don't think it's a coincidence that all units from theses projects take longer to do, and make the PPD production drop. It's been like this for a while now. And by the way, I have a RX5700XT. So I doubt that this is a CUDA only problem.

You can see the number of atoms in each project on the Project Summary page (linked from the top of the forum) https://apps.foldingathome.org/psummary ... 169xx projects vary in size.
1: 2x Xeon E5-2697v3@2.60GHz, 512GB DDR4 LRDIMM, SSD Raid, Win10 Ent, Quadro K420 1GB, FAH 7.6.21
2: Xeon E3-1505Mv5@2.80GHz, 32GB DDR4, NVME, Win10 Pro, Quadro M1000M 2GB, FAH 7.6.21
3: i7-960@3.20GHz, 12GB DDR3, SSD, Win10 Pro, GTX 750Ti 2GB, FAH 7.6.21

Project summary shows it as core 22, and so does the posted log

https://apps.foldingathome.org/psummary

Also I'd rather not discriminate, while I am favoring donating to COVID causes that doesn't mean I'm opposed to donating to other causes. What I do want to ensure is that things aren't regressing.

I haven't observed anything else for other 169xx projects, AFAIK this is 16921 only.

For reference, I have taken note of significant PPD drop with 16918, 16905, 16904, 16921 (theses are the one that I have noticed) On a non-CUDA card (AMD). In facts, most of the days my production dropped below 800 000 PPD, I had two of theses unit in one day. My card should be able to handle 1.2 Million PPD per day.

Please note the COVID-19 Projects can be run on FahCore_22 or FahCore_a7 or FahCore_a8.

You will need to look at the individual Projects (https://stats.foldingathome.org/project?p=11747) and in there, you can see the cause set to "covid-19" while others will have different causes or nothing at all which are all valid.

I can't speak for AMD but on my 2070 Super on CUDA 16918 (113, 34, 109) is running at 2.56mPPD which is within expected deviance based on observed average variance for CUDA cores on that setup. At least for CUDA cores it seems to be 16921 alone.

1) The problem with projects with low atom counts on a GPU which performs well when a project is capable of being highly parallelized has not changed. WUs tha make good use of a large number of shaders will always see reduced performance when the protein can't make efficient use of all of them. Proteins will always vary and the projects that happen to be assignable at a specific time may be less productive. (See 3 below.)

2) The purpose of the benchmarking project is to make optimum assignments of WUs to GPUs. That project has not yet been implemented yet. Data is still being gathered -- which includes making non-optimum assignments so they know what your GPU can actually produce. That's NOT regressing; it's data gathering

3) Even when the benchmarking project is fully implemented, there will be wide variations. If the only projects available happen to be non-optimum, the two choices are makeing a non-optimum assignment or tell you that there are no projects that fit your hardware. Would you rather have your GPU idle or earning points at a lower rate?

4) FAH is guilty of points inflation and it changes your expectations. I have no specific knowledge about your GPU, but maybe its average production should be lower than your expectations I'm sure you only want the highest numbers you've ever seen, even if they happened to be higher than they should be.

I was under the impression based on the FAQ that all projects were run on a standard benchmarking setup and points were determined from that. Is the point allocation method changing?
