Re: Is the WCG Community giving up on Open Pandemics?

What is RAC?


That's BOINC's Recent Average Credit score, a rolling average. I'm thinking in terms of BOINC credit rather than WCG points. I generally track progress on Free-DC, which uses BOINC credit for its stats.

https://en.wikipedia.org/wiki/BOINC_Credit_System

ETA: Per the help page , multiply BOINC credits by 7 to get WCG points.

smile Re: Is the WCG Community giving up on Open Pandemics?

OK! Good to know. TKS.
Time now to do my calculations

how this thread derailed from discussing Open Pandemics project to various hardware things related to Raspberry Pi
Yes. But it caught my interest on a subject to which I did not get all the answers I wanted. biggrin

Re: Is the WCG Community giving up on Open Pandemics?

OK so the RAC points correspond to what the other two users have said about points 5000-6000 points per day. This is what my old T400 does but it uses about 4-5 times the power to do the same job.

If I switch focus to points instead of watts and use another machine of mine as an example which puts out about 32,000 points per day (~4500 RACs) I would then need about 5 Pi 400 (using 900 RACs/day) to output that for about 35+ watts. That's over $675 CAD ($525 USD). For that amount I could swap out the motherboard of another machine (~19000 points) with one which will be a monster cruncher (Xeon/Ryzen)

So I'm sticking to my original idea and dropping Pi from my plans. If I had a Pi around I would use it to crunch.

Re: Is the WCG Community giving up on Open Pandemics?

Since this thread is de-railed. I'm following the pi vs the world.. I am not sure on the conversion but this is what I see with 4 pi4b's with kubernetes running 12 nodes of boinc.

Avg. Run Time Per Calendar Day (y:d:h:m:s) 0:009:20:22:17
Avg. Run Time Per Result (y:d:h:m:s) 0:000:09:12:51
Avg. Points Per Hour of Run Time 61.98
Avg. Points Per Calendar Day 14,649.40
Avg. Points Per Result 571.07
Avg. Results Per Calendar Day 25.65

Not sure how the lines up against a dedicated machine but I think it works good and is a good geek.

Re: Is the WCG Community giving up on Open Pandemics?

Yes it has de-railed. Should now be in hardware but....

We were comparing 1 Pi 400 to my very old Lenovo T400 (2008). Show us the stats for 1 device so the comparisons can be using the same data. Is that Average of all devices (4) or Average over a time period. Even with my stats like you show I am not certain.

The argument is that the Pi is way more efficient than my T400 in power usage(x5). My counter argument is how many Pi's does it take to match my i7 3770 (2012) in sheer points. Then how many Pi's compared to a Xeon/Ryzen (which I don't have but have my eye out for)?

Then do the maths for watts, $, and space.
