Default PS3

Will Prime95 ever run on PS3?

Looking at Folding@Home stats: http://fah-web.stanford.edu/cgi-bin/...?qtype=osstats 28672 active PS3 which is 12.6% of the 226889 active CPUs deliver 702 TFlops or 73% of the total 957 TFlops.


Looking at PS3 specs from wikipedia: http://en.wikipedia.org/wiki/Ps3

Quote:
PlayStation 3's Cell CPU achieves 204 GFLOPS single precision float and 15 GFLOPS double precision.
So that would be 15 GFLOPS for Prime95. But 702 TFlops / 28672 active PS3 = 24.4 GFlops, but perhaps Folding doesn't use double precision.

What's stopping it from being run on Linux on the PS3 right now? Do none of the GIMPS clients work with the Cell processor?

Also, assuming only 15 GFLOPS can be gained from it, it has the same power as a Intel Core 2 Duo E6600 2.4 GHz does. Nothing spectacular, but still definitely worth getting a GIMPS client to run on it. That CPU at Newegg is $313.00, a new PS3 is $599.99 (both USD), so it wouldn't be cost-effective to buy a PS3 as a cruncher, but if you're looking at buying a gaming console anyway, the PS3 would probably be the one to get.

There is no Prime95 optimized and compiled for the PowerPC architecture. Cell's main processor is basicly a PowerPC chip used in old Macs. You can try running GLUCAS on it. Its runs on just about any platform, but isn't optimized (so, it probably isn't worth it).

It seems to be working well (with an optimized core) for another project.

"...we have measured the PlayStation 3 processing RC5-72 work units at close to 170 Mkeys/sec, easily making this the fastest hardware platform our client has been ported to. This is more than 22 times faster than a computer with a Pentium 4 processor running at the same clock speed as the PS3's Cell processor." -decio .plan

A PS3 completes the following work in dnet per day

RC5 - ..3,365 blocks consuming just 133 watts.
OGR - 22,000 gnodes consuming just 134 watts.

Average, as each day is slightly different than the next.

Watts measure power, not energy.
Did you mean 3,365 blocks consuming (133W *24H / 1000=) 3.192 KW/h?

Obviously I was stating what a kill-a-watt, or similar device, was reading. ;)
That's much better than a PC at say 7.2KW/h to 9.6KW/h and it would take many many many more PCs to achieve an equal amount of work.

Sorry to nitpick but you are talking about KWh and not KW/h. Power per unit time does not make sense.

Ok, now that we've managed to detract from the initial message...
The PS3 running dnet will cost you about what a 100 watt light bulb would cost you if left on 24/7/365.

Consider the use of one 100 W light bulb (0.1 kW) used for 10 hours per day.
This will consume 1 kilowatt-hour per day (0.1 kW × 10 h).
If a power company charges $0.10/kW·h, then this light bulb will cost $0.10 a day and $0.70 a week to operate (0.1 kW × 10 h × $0.10/kW·h × 7 d/week.)

I'm not sure if my idea is good or not, I'm just throwing this out there.

If someone managed to compile a Linux PS3 LLR, sieve, ecm, p-1, etc., could that possibly encourage people to get involved in porting apps? I had a programming class when I was 15 and not much after that, so I'm not real savvy on optimization stuff. Would the code need to be reworked entirely for the various things, or could it be processed in distinct chunks; a lot of work, but able to be tackled in chunks?

The reason I ask this is I've got a TON of free time pretty much all of the time. Other than my job at KFC and some holiday stuff going on with my family, I pretty much can do what I want. Within the past month or so(I'm on a new medication that makes me more capable, not a lazy bum who's been intentionally living on handouts) I've attempted to set some goals for myself. I still have a rather severe social anxiety disorder, plus a movement disorder that exacerbates things, but for anything that can be accomplished with diligence and an Internet connection, I either want to do it or help support people who want to do it.

If someone thinks compiling a Linux PS3 version that simply works, but not necessarily well, for anything that people think could ultimately perform well on the PS3, would kickstart the porting that a lot of people want, I want to be the guinea pig. But I need to know I can accomplish the task, either through committed people, or simply reading the right forums and bugging people with questions.(Not intentionally bugging people, but I know I annoy some people, online and off.)

So what do you guys think? Should I be racing around the Internet, trying to find a PS3 deal aimed at super-late shoppers, or maybe wait for a New Year's type sale? Or should I just forget the whole thing?
