Greetings fellow knights!

I don't pay much attention to all this, but every now and then I poke my nose into the goings on. Had a few things I was wondering about and couldn't find the answers after a bit of searching.

What's up with a lot of the top producers running the Milkyway project almost exclusively? Does it give better credit than others? Are all BOINC projects more or less equal in credit per CPU hour?

How do people get 250,000 credits per day from one machine? Is there some way to have one box do all the reporting for others?

Is there much or any advantage to running the latest BOINC version? Mine is 6.10.36. BOINC page has 6.10.18 for DL at the moment, that seems odd to the uninformed like me.

In one word, Graphics Processing Unit Crunching. Some applications benefit greatly from the processing power of GPUs. MilkyWay is one of them. There are a few projects out there that have GPU apps:
MilkyWay - needs a double precision GPU
Collatz - accepts many different GPUs
DNETC - only has GPU apps
GPU Grid - only cuda (nvidia)
Seti - only cuda (don't know too much about that one)
Einstein - cuda, but also needs a cpu core to run alongside

Other projects have tried GPU apps and more may be coming in the future.

Credit comparison - http://boincstats.com/stats/project_cpcs.php

To get many credits on one machine - say you have a quad core or an i7 (8 core) with a couple of GPUs. If they are high-end doo-dads, you get mucho credits.

Boinc version - I am running 6.10.36 on one machine and 6.10.43(?) on another. It seems like they were moving right along and then for some reason they bumped back the recommended version back to 6.10.18. Must have been some bug they discovered. But mine have been running smooth, so I kept it. You need at least the 6.10.x version to do GPU shrubbing, but as far as performance, I think they are the same.

Hope that helps!

Ni!

.43 and .44 alpha had a glitch with video card projects not properly restricting what wus you got based on your gpu, so they went back to .18 .

Thanks for the info,

No GPU, so none of that for me. Obviously I'm not too serious about maxxing out my credits. I keep BOINC off while using the computer, not that I notice it slowing down, but the fan always kicks on faster when it's running which I'd rather do without.

I've been plodding along with this for nearly 10 years already and just recently went over 1 million. At least I will once it syncs up again since I changed my email addy and forgot a project until yesterday. Quite the tortoise, I know!
