Can Einstein@Home pass the 1 Petaflop (1000 Teraflop) barrier?

The computing power of Einstein@Home has exceeded 950 Teraflops for the first time since the project was begun in 2005. Based on the rate that our computing power has been growing, I am hopeful that Einstein@Home will pass the 1 Petaflop barrier before the end of 2012. Einstein@Home volunteers: please keep your computers running over the holiday season, and please sign up any new ones that you might receive as a gift!

This may be hard since SETI is back in action and shares GPU-s :(

Mayby another power failure .... ;)

We are working hard, in our challenge...

December maximum power is trying to increase the power of einstein@home and also try to finish the S6LV1 before new year...

But is very difficult because good computers compute bigger GPU data than CPU...We are crunching because is hard to get...

Hello Bruce I am as excited

Hello Bruce
I am as excited as you that the project has accomplished so much. If I had the money, I would place more resources in operation to do more work. I can assure you though, that I intend to keep the resources I do have working 24/7, as they do all the time. I think we are going to make the goal by the end of the year.
Regards,
Mark W. Patton

We will try to do our best and repeat/pass that mark today!

If only i know how to make the 590/690´s use more than 50% of it´s real power... as is easy to do with his cousins 560/580/670/680... 5MM will be a easy task... SNIF!!!

But still planning how to do that in the drawing board!!! Any help is helcome! (Yes, I allready increase the BRP factor...)

Do you have any idea Bruce

Do you have any idea Bruce what we will compute after finishing S6LV1 ? Are there any other project ideas beside the BRP4 Arecibo pulsar search? And maybe you or anyone else can answer one more question: Is seti@home still doing serious scentific analysis on their data like einstein@home does?

Thanks for any answers, Merry Christmas and a happy new year!

Greetings from Munich, Germany.

The Einstein@Home project is currently testing an extension of S6LV1 to higher frequencies. Hopefully coming soon to a computer near you!

We'll continue with the BRP4 search indefinitely. First we need to catch up with the data backlog of about 13,000 beams (this will take a couple of months at the current rates) then we'll continue in the steady-state. PALFA is taking about 50 new beams of data per day, on the average, so this search will be running for some years, at least for as long as PALFA is collecting new data.

I don't have any inside knowledge of the SETI@Home project, but have always thought that the basic idea is outstanding. This is high-risk/high-value research, in the sense that the odds of success are not high, but the payoff is huge.

I personally am entirely sure that there is other life in our universe, but finding definite proof of this would be one of the most important discoveries ever for mankind. So personally I would be very happy to see SETI@home succeed in its goals.

Happy Holidays, and thank you for supporting Einstein@Home!

I just added a cheap GPU to one of my less-capable crunchers. However, I set up new prefs for it to do GPU work only, and then I set it to no new tasks until it finishes all the CPU work it has on board. There is only one Einstein unit left, but a bunch of Seti. It should finish that up in a week or so and then I'll unleash the GPU for both projects.

Fingers Crossed that we can

Fingers Crossed that we can Achieve That Goal. My 2 Computers are almost Running 24/7. I just put them in Hibernate or Sleep Mode for a few hours or overnight, each couple of days, just to give them a rest. I only Shut Down about once or twice a week. I'm not expecting any New Ones at Xmas, but hopefully will be getting my Old Computer Working Again, and if I do, I'll be Activating it as soon as I can. I currently Run 5 Projects on My Desktop: Seti@Home, Einstein@Home, Cosmology@Home, Rosetta@Home, Milkyway@Home. I also have Orbit@Home, but have not done any work as yet, due to its Inactivity. On my Notebook (Laptop), I only Run Seti@Home due to it only having 2GB RAM and if I Run too many things on it, everything either Slows Down or Crashes. Even without any Programs Open, The RAM Usage is between 60 and 90 Percent. I do quite a few Einstein Tasks on my Desktop, and My Laptop is always loaded with Seti@Home tasks (I have had 35 Seti Tasks on it at one time). I actually got involved in The (Other) BOING Projects through The S.E.T.I. Program.

Hi Bruce,

could you give us some information about the plans for publications you have for the already processed data? Will there be publications about the gamma-ray searches? And what about the S6 search? The computations ended almost a year ago or so and I am wondering, if there will be a similar paper as for the S5 search that was published a few month ago. And what about the pulsars found in Arecibo data? Will there be a publication?

Cheers,

Vegard

Seti@Home has been giving fits over the past month ...and I know as an Einstein cruncher who had his project set for "no new tasks" while crunching SETI has returned full time after 3 years off and crunching high numbers. I`m sure other Seti crunchers just got fed up with the condiciton of the project and left, thus returning to Einstein@hoime like I did./...good luck and I hope yo umake it.

After fossicking about I've

After fossicking about I've rustled up a couple of i7 machines with NVidia 560+ cards - they can do some fine E@H work when my kids aren't online gaming ( they have to sleep sometime ) - and I reckon I may find some more .... :-) :-)

[ BTW : if you have a Linux machine may I recommend using the 'per distribution' method of installing BOINC, it does an end-run around the silly business with the later Ubuntu's re. logging on as root ]

Cheers, Mike.

( edit ) As for heat ( summer DownUnda ) : I have found some great water cooling units that are sealed from Corsair ( H80i for ~ $140 AUD ) that drop the CPU cores down to ~ 25C. Big & quiet fans. Choice of brackets to mount to the various CPU form factors. Heat exchange right over the chip. No trouble whatsoever.

Mike, those fans are listed as 120mm 2700 rpm. A pair that size running that fast would not be welcome companions in my study. What rpm do you find yourself actually running? And how do you find the fan noise?

Ah well, the part of the unit that sits on the CPU has a large push button on it ( or later models have an on-screen widget via USB if you like ) to cycle/select different behaviours for the entire assembly. From 'gentle' to 'aggressive' response, determining the fan speeds and the coolant pump rate. So the 2700 rpm is the max for that. I set it to gentle and for me it occasionally revs up but not for long.

[ One can reduce the activity of the case fans on account of having the CPU cooler active, so there's a dB gain there too. ]

Cheers, Mike.

Why should Einstein@Home pass the 1 Petaflop (1000 Teraflop) barrier this time?
If I understand right the S6LV1 search progress is almost completed and in addition to this the sensitivity of interferometers has to be increased before creating new gravitation wave work units?

Note quite. The current run will be extended to cover higher spin frequencies, and after that is done we are planning to have a new search, using different methods but not waiting for the detector upgrades. See this thread for updates:

There's also BOINC's "debt" system which will have an effect: while SETI@Home was not able to distribute new work, many hosts participating in both S@H and E@H have received more work (and later credits) from E@H than they usually would according to the chosen resource share. BOINC tries to correct this in the long term by throttling the work fetch from E@H until the "debt" is repaid. Fair enough.

Congratulations on almost

Congratulations on almost reaching 1 Petaflop!

I wish I could do more to help the project. I have the hardware to run about 1200 BRP4 tasks and additional S6LV1 tasks per day but not the bandwidth/throughput to keep all my systems crunching full time. My hosts seem unable to download at a rate of more than 1.4 Mbps per host from the Einstein download servers. Since I have a limited window each day of unrestricted bandwidth, it has been difficult to keep the systems fed with work.

My hosts seem unable to download at a rate of more than 1.4 Mbps per host from the Einstein download servers. Since I have a limited window each day of unrestricted bandwidth, it has been difficult to keep the systems fed with work.

That made me wonder how compressible the data is, so I tried bzip2 compression on a couple of files:-

p2030.20120101.G177.93-02.24.N.b1s0g0.00000_543.bin4 2098320 bytes in=> 450585 out
h1_0403.95_S6GC1 8445248 bytes in => 7130498 bytes out

So based on this limited sample, it appears BRP4 files are pretty compressible (almost 5x) but SL6V1 less so (<1.2x). If it's possible to somehow arrange compressed downloads for you, you could get almost 5 times the work in the same bandwidth.

Is it possible to proxy e@h downloads? I think it downloads with wget or curl, so in principle it seems possible to insert a compress/decompress step.

edit: compressing about 20 BRP4 files gave an average compression of ~3.58x; files fell into 3 roughly similiar sized groups, with compression rations of 4.72x, 3.73x and 2.84x)

I think that would be fantastic if there was a way to compress the data down in BOINC either with Bzip2 or possibly LZMA2 (xz). The compression ratios that you are seeing with BRP4 files are excellent. The bandwidth is the main item that has kept me from bringing more resources to the project. The previous reduction from 32 MB to 16 MB per task made by the project team was very helpful. However, even at 16 MB per task, I am looking at almost 19 GB of data transfer per day to bring all my resources online full time.

From [trac]wiki:FileCompression[/trac]: The BOINC client can handle compressed downloads using both the mod_gzip and mod_default mechanisms provided by Apache. However, resumption of interrupted downloads doesn't work with either of these methods, so we don't recommend using them.

For application version files, you can specify a flag. This will cause the file to be transferred in compressed form to 7.0+ clients.

and

If you include the tag in an output file description, the file will be gzip-compressed after it has been generated.

The gzip_when_done is only supported in client version 5.8+.

I wonder if it would be possible to have the BRP4 application itself link to one of the different available compression libraries and have the application handle decompression of the data files before starting processing of the data.

Thank you for looking into

Thank you for looking into this. I did some compression experiments with the LIGO data (currently used in S6LV1), but not with the BRP data (at least not since ABP days).

This is what I'm planning to do: Link the application with zlib, so it can easily handle both gzipped and plain data, then add gzip as the last step of pre-processing. Shouldn't require much of a change.

We are already using the gzip feature of the BOINC Client for result files in BRP and GW work (), in fact this is why Einstein@Home requires a minimum Client version of 5.8. But I wouldn't rely on that feature for input/workunit files.

I did some testing last night and compressed a few of the .bin4 files with gzip. The files compressed from 2052K to 464-468K. This is a substantial reduction in file size.

I think that linking the application to zlib would be very helpful. Thank you.

RE: We'll continue with the

We'll continue with the BRP4 search indefinitely. First we need to catch up with the data backlog of about 13,000 beams (this will take a couple of months at the current rates) then we'll continue in the steady-state. PALFA is taking about 50 new beams of data per day, on the average, so this search will be running for some years, at least for as long as PALFA is collecting new data.

Since we are processing an average of 166beams/day, does that mean that we are going to have a shortage of BRP4 tasks to feed all the GPU´s?

I figure my home computing

I figure my home computing taps me for 50 cents per day maximum. I'll balance my cost by having a glass of water rather than a can of diet coke.

There are only 10 kind of people in the world, those that understand binary and those that don't!
