Re: Mind Boggling !!!!!!

Could he be playing with VMware, virtualizing one machine into 5 (or 35) more, each with a different identity (how?), so that at the end of the day, those five virtual machines report the exact same number of credits (produced by the physical machine), 5 times?

I hope I'm wrong ...

Re: Mind Boggling !!!!!!

Looks like Mr. P has loads of cash, but that still doesn't explain the identical numbers of credits, which I have never seen for any other user or machine. He also appears to be readily able to customize virtual machines (apparently entirely possible), and he is clearly very good at 'beating the odds' - whatever that may take. Such stuff is way out of my depth, tho, and I recognize when I should let more qualified folks speak on the matter.

Re: Mind Boggling !!!!!!

What if Mr Postnieks were invited over and asked to comment on the speculations at WCG forums where's he as yet is not volunteering his computational prowess? [Beating the odds you for instance do at projects that give a fixed credit per result and setting a limit of minimum results and exit on completion, then script that for a daily scheduling... these ways are documented in the various BOINC manuals]

Re: Mind Boggling !!!!!!

Excellent idea - who has a GPUGRID account?

I'm convinced something is amiss - he has different machines, with different specs, all producing the exact same number of credits. For example, he has an i7-3770K, (1 CPU, 8 cores), producing 405,450 credits yesterday, and he has an i7-3930K, (1 CPU, 12 cores) ALSO producing the exact same 405,450 credits. In addition, there are three E5-2620 machines (6 CPUs, 12 cores), producing the same number, 405,450.

You know that there would have to be SOME difference between those values.

Again - I'd much rather be wrong, but this is just too good to be true. In addition to producing 39,000,000+ credits per day for GPUGRID, he's ALSO producing 34,000,000+ credits per day for Distributed Rainbow Table Generator: http://www.gpugrid.net/show_user.php?userid=81276

It's just odd

Re: Mind Boggling !!!!!!

Hypernova said: I can only be astonished at the cost this represents and the running costs in terms of electrical consumption probably over 150 kilowatts.

Per his personal website(http://www.naymz.com/erikpostnieks981007 ),
Mr Postnieks address is listed as New York, NY, where electricity is $0.201 per kw .... ($0.201 x 150kw x 24hrs/day x 30 days) = $21,708 per month x 12 months is $260,508 per year ... that's some volunteering!

I'm concerned that there could be a way to 'fake' contributions to a distributed computing project. It would be very bad for the reputation of distributed computing in general, and very bad for the science work that is potentially being submitted 'in error' for a specific project.

Shuttin' up now.

In addition, there are three E5-2620 machines (6 CPUs, 12 cores), producing the same number, 405,450.

Well, the project is called GPUgrid for a reason.

Meaning, it doesn't matter if the computer has 1 cores or 12 cores, as long as it's got the same type of GPU.


As for getting same credit on multiple computers, a quick look reveals GPUGRID has multiple-sized tasks, where one group of tasks has the "8-12 hours on fastest card"-designation. Just from this description it should be fairly obvious a single GPU will finish either 2 or 3 tasks within any given 24-hour period. On top of this these tasks gives either 112625 or 135150 points.

So, 405450 just means 3 of the 135150-point tasks was finished, this is trivial to manage if dual-GPU.

So, with 100+ active computers, based on how few tasks per day any given computer can finish and how little variation in crediting between tasks where is for GPUGRID, I would actually be much more surprised if where wasn't any computers getting the same credit per day. smile

Re: Mind Boggling !!!!!!

I would rather be wrong, it's my comfort zone.

Mr. Postnieks electric bill must be massive - someone from one of the science goups should send him a case of champagne out of their grant money, for all the work he's doing for them.

Re: Mind Boggling !!!!!!

The 'interesting' Mr Postnieks is in Park City Utah, methinks .

" It appears he put most of these use around 01/17/2013 as that is when his numbers went up"

Mr Postnieks had a very busy day on 01/17/2013.

He appears to run an investment company with 'six ' employees and no clients.

And,access to a 2 petaflop supercomputer.
