Topic 198434

I decided to switch my 64 core server over from folding@home to einstein@home.

Have a couple pictures of rarity, my 64 core server.


I did have it run einstein@home before for a little while, maybe a week or two, and switched it back to folding@home. I think I will keep it on einstein@home for the foreseeable future.

I do have a question about video cards... einstein@home can use video cards, but only on some projects? I browsed the threads a little bit and could only tell that some people use video cards.

Thank you so much for doing that. Bruce will be tickled pink that you have chosen this course of action. If you read his recent good news you should note the little comment, "... please sign up your computers and disable their sleep mode!" which should give you an indication of the volume of exciting work to be crunched.

I'm sure I can speak for all the regulars around here by saying that your contribution will be most welcome. We hope you enjoy your stay and we all look forward to the discoveries that lie waiting in the data to be crunched.

The potential is there for all the science runs to eventually have GPU apps. The attraction of the GPU is the large increase in productivity - perhaps an order of magnitude or more.

At the moment there are well tested GPU apps for the Binary Radio Pulsar (BRP) searches. The particular searches are BRP4G (Arecibo) and BRP6 (Parkes). The data comes from the two radio telescopes mentioned. Some BRP4 data is reserved for mobile devices and Intel GPUs. There are often shortages of BRP4G for discrete GPUs. There's no shortage of BRP6.

The other searches, FGRP4 (ending soon) FGRPB1 (replacing FGRP4) and the very latest GW search O1AST (Observation run #1 All Sky Tuning) are CPU only searches for the moment. During the coming months it is likely that GPU apps will be developed progressively for both O1AST and FGRPB1.

With the discovery of gravitational waves in the engineering testing run that preceded the start of the official observation run #1, I would guess there will be intense interest in seeing if continuous GW (rather than those from a single cataclysmic event) can be seen in the O1AST run that is just getting underway here. E@H is well positioned to look for these.

These are truly exciting times. Once again, thank you for joining us.

Cheers,
Gary.

The computer pulls about 600

The computer pulls about 600 watts under full load, 700 if I soft-overclock it from the stock 2.1gighz to 2.4gighz. Compared to a modern video card the amount of stuff it can do is nothing though.

Maybe one day I'll put a newer generation processor... like the AMD Opteron 6376 or something

Based on the crunch times currently showing (~60ksecs) the theoretical daily production is ~92 FGRP4 tasks or 92X693=~64K RAC (Recent Average Credit).

By way of comparison hostID 430276 (one of mine) draws about 170W from the wall and produces ~7 FGRPB1 (CPU) and ~19 BRP6 (GPU) tasks per day. It currently has an actual RAC of ~90K which is close to theoretical. It's a G3258 Pentium dual core and the GPU is a single AMD HD7850 running 4 concurrent GPU tasks. I quite like the concept of a budget CPU to drive a somewhat more powerful (but still power efficient) GPU. That machine was built a couple of years ago when there was a different app which penalised multi-GPU setups. Now the 'penalty' has been resolved so that multi-GPU setups are more attractive than they were.

Cheers,
Gary.

Nice rig. Welcome to the herd, I mean project, fellow team member. :)
Although looking at your account date, maybe welcome back is better.

Heh, yeah... Oh, I was just stalking doing some team statistics earlier today and did you just change your nickname? I was just asking about you in the IRC channel we have and...

Looks like you could use a case... If that were on my wall, I would've bumped into it and pulled things out by now.

Oh, be still my beating heart. Fortunately the price includes free post-divorce counselling .... :-)

Cheers, Mike.

But that's for the whole shebang!!!

Only a processor upgrade was mentioned. Just need 4 of these!! :-).

I think I'll stick with my Pentium dual cores and lowly i3s :-).

Cheers,

It seems like these days that

It seems like these days that most of the larger distributed computing projects are able to use GPUs a lot better than even just a year or three ago. Typically whenever I consider new processors or another badass build, it kind of falls short when GPUs are considered.

It still might get an upgrade though from ebay pullout processors :D

Right now the computer is hanging up in my machine shop, because industrial electricity is about half the price of residential electricity.

I also have some pc's with lots of cpu cores, none with 64 in them though, and use them on projects that do not have gpu apps as I feel they need some love too. I have 3 pc's with 16 cpu cores each, thru hyperthreading, they each have 2 quad core Opteron cpu's in them.
