NaCl PPDs up by 20%?

Postby ProDigit » Tue Feb 05, 2019 11:17 pm

I've been running NaCl for the past month, and know how much PPDs I usually get per computer.
Now it appears like I am seeing a 20% increase over the max results I usually get, on all 3 computers.
Is this just a different WU more optimized for NaCl, or is there something going on with the PPD rating?

Project 14211 seems to be giving a lot more PPD. Maybe it is smaller than the other projects for Nacl?

Project 14211 is a newly released project. As such it is somewhat different from the previous NaCl projects and points may need adjusting at some point after they get enough returns to see if the points value is consistent. Due to the nature of the NaCl client and assigning WU's, it is a bit more difficult to benchmark a project before releasing.

The benchmarks are going up and down, so it's definitely a specific WU.
Average PPDs of my PC are 10k, and they jump up to 13k PPD.
On my other PC it's 12,4k PPD and they occasionally jump to 16k PPD.
Last PC runs mostly around 6k PPD, and I've seen it hit 9k PPD.

So I'd say that's around 30% high estimate for that one WU.

Reading high on 9021 and 9022 as well.

Hopefully they're worth more than the (now reduced) 42 points of a 'normal' NACL WU, as these usually process in about 14 minutes, whereas I've just had my first P14211 WU and it estimates completion in about 55 minutes...

You didn't tell us how many CPU threads were being used or on what CPU. Those specific numbers would not apply for someone else with a different number of CPU threads being used. (This also depends on the slider setting as well as the hardware.)

Mine actually went down in time.
They used to do 0.1% per second (~15-20 min per WU), now they're doing slightly more (~1.5%/sec) (~10min/WU).

Any statement about benchmarking iis meaningless unless you describe your hardware. A core2.duo @ 1.06 GHz will not process WUs as fast as a 32-thread Ryzen @ 4.0 GHz.

Then, too, a WU that runs on your machine in 15 minutes should earn 1.5 as many points as a WU that runs for 10 minutes on the same machine. The whole idea of benchmarking is to maintain a constant PPD, and that can either be adjusted by altering the points or the duration of the WU.

Project 9021 seems to be consistently running at 2x PPD compared to the other Nacl projects. Normally Nacl runs at about 5,000 PPD on my laptop. 9021 runs at over 11,000 PPD.

Project 14211 seems to be a mirror of 9021 in the case of the increased points.

Project 9020 is also a mirror of 14211 and 9021 in increase points.

Are you going by the displayed PPD, or calculating one after determining how many NaCl WU's have completed during a time period and the number of actual points credited? The WU's from projects 9019 to 9022 give 42 points, the recently released 14211 gives 21.

The PPD display in the NaCl app for Chrome appears to be giving inaccurate estimates, that is to be checked on.

It was just based on the display, and the estimated PPD, and how quickly the work units were finishing. Your explanation accounts for the difference then. Thanks for looking into it and providing a response.

Nacl is unstable, restart every day.
So what is wrong?

Yeah, estimated PPD on the NaCl runs a little high (as high as 2,5x on some WUs).
We're receiving like 24 points per WU, but NaCl website believes we're getting 48 points.

On 9021 and 9022 I get about a 20% overage.

Return to NaCl client (Chrome);
