Hi, I've noticed a huge difference in credits awarded between SETI and Einstein at home.

Running 1 GPU (rx 560) task at Einstein@home for about 24.5 minutes gives me 3465 credits. (141 credits/min) Running 1 GPU (rx 560) task at Seti@home for about 13.5 minutes gives me 53-57 credits. (4 credits/min)

Why such a big difference?

Because Seti uses "cred it new" and Einstein uses the older model of awarding credits. This is a very touchy subject with Seti trying to 'force' projects into using their concept of awarding credits at every project and the projects each having their own agenda and doing things their own way. Some projects use the data we crunch and then provide it to other places, some have gotten paid for our crunching data, others have shorter time horizons then other projects o will pay more credits to get the work done faster, etc, etc, etc. There are as many reasons to not follow Seti down this path as there are projects out there.

The key is to not compare credits between projects but to only use them to compare your output with other computers within a project.

Thanks for your reply.

Thanks for your reply. Basically that means that one "credit' isn't the same between one project and another, which it really should be. 

Here's what a "credit" is according to BOINC:

Computation credit

A BOINC project gives you credit for the computations your computers perform for it. BOINC's unit of credit, the Cobblestone (named after Jeff Cobb of SETI@home), is 1/200 day of CPU time on a reference computer that does 1,000 MFLOPS based on the Whetstone benchmark

Eventually, credit may reflect network transfer and disk storage as well as computation.

Credit has no monetary or other value; it's just a measure of how much work your computers have done.

Credit and FLOPS

The average FLOPS (floating point operations per second) achieved by a computer or group of computers can be estimated from its Recent Average Credit (RAC) as follows:

GigaFLOPs = RAC/200
TeraFLOPS = RAC/200,000

(Remember that a 1 GigaFLOP machine, running full time, produces 200 units of credit in 1 day).

The credit figures for a particular day may be distorted if a project is catching up or falling behind on validation (the process or granting credit). Thus to get accurate FLOPS estimates you should look at average RAC over a period of a week or so.

That's what I said Seti has their way of thinking and most other projects have their way of thinking. Doesn't mean either is wrong or right, just means there are multiple ways of achieving the same goal, getting pc's onto projects to crunch! The key to credits is that 10 Billion of them and $10 will get a cup of coffee at Starbucks, BUT without the $10 you are NOT getting anything!!

But many of us who crunch Seti are working towards getting a toaster.

After crunching E@H for over a decade, I've gotten 3 space heaters.  :D
