PlayStation 3 Performance

[IronBits]

One PS3 averages ~228 Mnodes/sec - guessing ~20-22 T per day. :thumbs:

Kill-a-watt shows 114 watts being consumed under full load. :smoking:

Enjoy the :corn: while we sit back and watch the daily output and help yourself to the :fridge:

Oh, and before I forget my manners, here is the obligatory :hiya:in case I pass anyone. :)

[Bok]

What is that in Gnodes ?

i.e. what numbers can be expected in the stats (http://stats.free-dc.org/new/teamstats.php?proj=ogr25&team=Free-DC)

??

By looking up Magnav0x's recent scores, being close to what a single PS3 unit outputs, then,
looking at your pproxy stats, Free-DC OGR Stats and Official Stats we can come up with the following assumptions.
~230,000,000 nodes a sec equals ~20,000+ G per day or ~20+ T per day ...

Anyone else have a better translation from nodes/sec for G and T per day projected output?

You are correct. You will get 19,872 Gnodes per day. Bok, that's the number you'll get on your stats.

19,872Gnodes=0.230*3600*24

wow......... that is just a mind blower it is. :looney:

Bok in ppstats, I see this formula :
For past days: Mnodes/sec = nodes / (60*60*24) / 1,000,000
For today: Mnodes/sec = nodes / (seconds today / (60*60*24)) / 1,000,000

114 Watts are very impressive for about 228 MNodes/s, impressiv!!
For that output I'd need about 3 to 4 dualcore boxen, which need more Watts...
How many cpu cores are working in such a box?
Is it hard to setup a PS3 with linux?

[the-mk]

so you can "multiboot" into both systems? YDL and PS3 "standard gaming mode"?
If yes, I think I need to get such a box the next few days :D pre-christmas gift :D

[IronBits]

Yes, you can choose which OS is default. I have YDL as mine.
Or you can hold some key in and tell it which OS you want to boot, like Apple's Boot Camp where you can choose which OSx or XP/Vista you want to boot up.
If you are in PS3 mode, you can run Folding@Home as it has a native client for the PS3, play games or watch a Blueray DVD movie.
In linux mode, you can run dnet, ps3grid http://www.ps3grid.net or http://www.ps3grid.net/PS3GRID/PS3client/boinc_client_ps3grid.tgz boinc client :)

[IronBits]

21.09T or 223.32 Mnodes/sec or 21,087 Gnodes
per day

[paleseptember]

Those are some impressive numbers :thumbs: Especially at ~140Watts. Makes my power-guzzling quadcore look pale in comparison!

[the-mk]

might be the last question before I buy one: how about noise in full cpu load like d.net ogr?

[IronBits]

While running YDL and dnet, you can't hear anything from 3'.
If it's on the floor, and you are standing over it, I doubt you will hear anything.
At 2', I'm not sure if I'm hearing it or the fan on the TV or A/V equipment.
If I stick my ear right up on it, I know there is a fan slowly moving warm air out the back.
If you run Folding@Home in PS3 mode, I could hear the fan from 6' away and I believe it was running much hotter as it was doing a screen saver thing showing where all the other PS3s around the globe are located and making stupid wind noises. (thankfully you can mute the sound)
It silently runs YDL and dnet client - runs 7 rc5 blocks at one time.
You won't be disappointed - get the 40gb model with extended 2 year warranty because it will be running 24/7.
Also, just read the 40gb model runs cooler and quieter than the other models. :)
Go for it.! :hifi:

[IronBits]

might be the last question before I buy one: how about noise in full cpu load like d.net ogr? Did you get it ? :confused:

[the-mk]

No, I need time beside my work to drive to a store and buy it... maybe this week, or the next one, we'll see

[the-mk]

IronBits, can you add the most important info to a new thread and make it sticky? That would be nice!
Thanks!
BTW: today I bought one, I'm currently installing it...

[IronBits]

Excellent ! :rock:

Here is your sticky, if you find any other messages you want merged there, let me know.

After accomplishing the task of installing YDL on the PS3, I ran first tests of the client on it

to me it looks like core #2 is the best choice, but why does the client use #1 when starting it up?? What core do you use IB?

BTW: it is nice to have 7 cpu-cores doing work :D

:cheers:

[IronBits]

It's all on auto pilot, I haven't changed or done anything to the client configs or the YDL OS configs. plug and play.
Yes, 7 cores is what I see running as well.
To get to your PS3 node, use SSH from a PC. All you need to know is the PS3's IP addy, which you should be able to get from your DHCP Server(broadband router) ;)

Q6600@2.8 GHz averages ~169 Mnodes/sec, that's 14.6T per day.

[meep]

Urm too tempting, all in a tidy little package that I may use for games/films in the future...

1 ordered, linux install following IB's awesome guide could be tomorrow evening :)

:banana:

[em99010pepe]

Q6600@2.9 GHz averages ~178 Mnodes/sec, that's 15.4T per day.

[IronBits]

At what cost in electricity to run 24/7?
Go meep! :thumbs:
Thanks to BlisteringSheeps help, I finally got SIMAP to run on the other processor DNET doesn't use in the PS3. :D

For me it's free!!
