1) Message boards : Number crunching : Credit reduced (Message 1451)

This project uses the standard BOINC Credit system which happens to be "Credit New". You will find most people in the community are highly against its usage and have renamed it things like "Credit Screw" and have referred to it as a random credit generator. Several have spent years trying to make it make sense. Best to just support the "science" for what it is and not get too wrapped up in the credits here.

I asked YoYo back in October 2016 about badges. His reply was

I don't want to add badges.
I want the pure Boinc server source only with the basic badges which are available in it.


I hope that helps you and anyone else coming here looking for the same request.

There is currently discussion on whether to add this project to the DC-Vault. The admins typically like to get project admins approval before doing so. We have not decided fully to add the project just yet, but would like to know whether the admins here support including this project or not.

The project currently requires at least 4 CPU's. I don't know how many CPU's your laptop has and how much 25% of it is.


Are you sure? I ask because I have some dual cores (non hyperthreaded) picking up work just fine.

Results during the last couple of days have shown point scoring bouncing around between 1 point every 5 seconds to 1 point every 21 seconds for my 48 core AMD system.

I can only do some limited testing over the next day or two, but here is my 48 core AMD setup running Windows Server 2008 R2 and only has 16GB Ram.

http://yafu.myfirewall.org/yafu/show_host_detail.php?hostid=9889

CPU time was: 101,392.30
Credit was: 1,626.15
So, that means it was getting 1 point every 62.35 seconds on the first completed work unit.

I don't know how creditnew is really working, but it might be a problem for credit new, that there are phases in a yafu run where only 1 core is used.


Yes, I am assuming it is CreditNew that is the problem. It is just good for people to know this issue before they get discouraged by comparing numbers later and seeing heavy hitting machines not get rewarded accordingly.

The rac is still converging over time. As you can see the rac is still going down over different days. Only the 2-core rac increased.
I don't know how long it will take until the rac is nearly stable.

Well, looking at the RAC as I have broken it down, it looks like the 16 core also went back up. Don't look at the RAC number I posted because that is from this site. You need to look at how many seconds it was taking to earn each point. The 4 and 8 were the only ones really lowering over time while the 2 and 16 jumped around. I don't see this being "stable" at all after over 2 weeks of processing work. Maybe you are more relaxed on the issue, but I prefer something a lot more consistent.

2 core: 54, 60, 60, 107, 160, 137, 143, 115, 95, 91, 89, 96, 91, 93
4 core: 10, 30, 32, 30, 29, 52, 58, 65, 43, 40, 39, 38, 45, 38, 39
8 core: 2, 17, 17, 16, 17, 31, 39, 38, 23, 24, 22, 23, 33, 29, 28
16 core: 3, 13, 16, 18, 117, 137, 151, 143, 38, 38, 36, 41, 71, 68

You would also think that the scoring would be closer. The 8 core should logically be closer to half the time needed to get the same points as a 4 core. But it isn't. It is still off quite a bit. As noted above, I could get a 40%+ increase in points by running two 4 core VM's instead of an 8 core.

Wait, you think that going from 4 cores to 8 cores scales good?

2 x 4 cores = 2 points in 39 seconds
1 x 8 cores = 1 point in 28 seconds

What I would expect is 2 x 4 cores to = 1 x 8 cores.
However what we are seeing is that 8 cores is scoring less points. Then the 16 core gets really stupid. The same logic could be applied to the 2 core.
2 x 2 cores should = 4 cores but it does not. And we aren't talking a minor difference. This adds up. Look at it this way.

At 39 seconds per point, the quad core earns 2215.38 points per day. At 38 seconds per point, the octacore only makes 3085.71. Now, if you were to take that octacore and chop it into 2 virtual machines, then your 3085.71 would magically transform into 4430.76 points. That is almost a 44% increase in points for the same cores on the same rig.

So, I ask again, how is this scaling " looking good". I will concede that other factors may be involved but as the numbers have shifted over the last few weeks, I think the facts point to a disparity.


Too late to edit, but the octacore at 28 seconds per point not 38 seconds per point was intended.

Last test units are in.

2 core: 1 point ~ every 93 seconds RAC: 712.19
4 core: 1 point ~ every 39 seconds RAC: 1,774.69
8 core: 1 point ~ every 28 seconds RAC: 2,713.55
16 core: 1 point ~ every 68-71 seconds RAC: 1,477.31

Well...I'm going to wind down my testing. 18 days of crunching and the numbers still have not leveled even close to consistent. I would not recommend anyone to run anything past a quad core at this time on these apps. This is just my opinion, but Credit New certainly does not do MT apps justice and should be reconsidered here.

Quad core looking to be the sweet spot at this point. I wont be running this test much longer as we have a team challenge elsewhere. I just thought these numbers would be helpful to the efforts.
