Eric, fixed credit per WU works for me as long as it gives "reasonable" points when compare to CPU in regards to amount of "GFLOPs" done though there could be algorithm efficiency differences in GPU vs CPU which I'm not sure. Faster GPU card will be able to churn out more WUs per hour and vice versa, so they collect more points.

I looked at some asteroid WUs, they sometimes do vary a lot but most of the time less, from what I've seen. Nevertheless, I think on average, the run time will settle to some mean value. At least you are not alone.

It was paying around 20 per run sec on my GTX 1080 which is better than many GPU apps but not crazy. Now it's only paying 0.08 per run sec, 1/250 of what it was which is crazy low. It's worse paying than Asteroids on a GPU. Einstein pays 5-7 per run sec.


Maybe I'll try CPU and see if the points are better than GPU payout. :(

edit: If there is no significant point (not number of WUs completion) gain over CPU app, it certainly defeats the purpose of creating GPU app in the first place. I know some of us crunchers are crazy about points rather than the number of WUs completion. Like Asteroid, maybe pay a fix credits for each WU completion which is what is important to NumberField project, rather than the point. In general, the points are to attract crunchers. My one cent.

Once people realize the RAC possibilities here, expect more members to flock here. Especially with the limited # of GPU projects.


Agree. This will attract more crunchers, some who may love the high RAC and also good for the project admin (project completed quicker), so win-win for both parties. Further, I think the project admin (Eric) did a fantastic job in last year pentathlon and Formula Bonic sprints.

Looking at BOINCstats, NumberFields currently has 390 active crunchers versus 1897 in Collatz. Imagine if the number of active users doubled or perhaps more if the apps can support both Linux and Windows plus older AMD/Nvidia GPU cards. I know there will be lots of work ahead but this is definitely a good start.

Thanks Eric. From looking at your GTX 1050 results, the credit looks super-awesome. I think you ran roughly do like 690K PPD. Keep that credit score high :)

Now, wait until you get GPU code running.


Funny you should mention that... I just got a prototype working on my GTX 1050. It's about 20 times faster than the CPU version. Probably still a few weeks out before it's production ready though.


Awesome! I assume that if the GPU is 20 times faster than CPU, then you will get your result quicker too, assuming the calculation method is the same with both CPU and GPU(?). Please keep us posted. It is exciting to know what's coming soon and I'm sure some crunchers here are ready to fire up their GPUs when the task are available.

Eric, thanks for the stat. Very useful and I'm sure most crunchers who participated in the sprint are glad that there were no hiccups during the 3/4 day event. Kudos!

Hi Eric,

Out of curiosity, would you be able to publish an estimate of the server load and completion of WU increase before and after the FB sprint event? There are some projects where the server and/or WU generation can't cope up during the FB sprint. Don't want to put any names to this but those who participated in FB sprint will know what I'm talking about. Thanks.
