What do you expect from crunching Einstein@Home?

It's so nice to have an efficient app. Not having one makes the work take longer and does not take the best advantage of the computing resources available, which can be frustrating.

Thank you!

Just keep in mind that with the increased performance comes more power draw and heat. But overall efficiency jumps A LOT since the speed increase greatly outweighs the power draw increase. 

Yes, the temperature rise on the 1070 was 5...6 °C with speedup of 33% (from 12:45 to 8:40 on first test).

On my RX 570 (Ubuntu

On my RX 570 (Ubuntu 20.04.2), I am still seeing "Einstein@Home 1.18 Gamma-ray pulsar binary search #1 on GPUs (FGRPopencl1K-ati)", rather than 1.28.

Is this a mistake?  It is running faster than before. 

EDIT: I am seeing times of 10 minutes.  It was around 13 minutes before.

The power is about 110 watts, a little more than before, but a good tradeoff as noted.

So far the new beta 1.28 GRP

So far the new beta 1.28 GRP application is released for Nvidia cards only.

They are doing something.  It

They are doing something.  It may just be a change to the data.  But the times have been getting shorter for a couple of weeks now, though I don't check it often enough to know the details.

they haven’t changed the AMD app at all. 
 

make sure you are not comparing GW run times to GR times. You’ve crunched both recently. 
 

I do see some GR tasks that ran at 800 seconds on Aug 18th, then most after that ran at 600 seconds. No major change in the tasks. Were you by any change running a different number of multiples? Like 3x vs 2x or 2x vs 1x.

You can compare the GR tasks yourself.  They are all 1X.

(I run the GW 2X).

The progression was consistent at 30 minutes a few weeks ago (no longer shown), then 13 minutes, and then 10 minutes.  There was not much variation within the groups.

By the way, they are supported by six cores of a Ryzen 3600, so they are relatively fast.

But the GR was just a test of the beta; I am out until cooler weather, and will run the GW then.  Thanks for looking into it, but there is not all that much data.  It is just puzzling to me what it is.  Who knows, maybe a library update?

Do you like to do crunching as a hobby?

Do you like to do the crunching because it's fun?

Do you crunch to see how many BOINC credits you get from Einstein@Home?

What is YOUR reason for doing the project Einstein@Home?

George,

In the abstract I support science.  But my immediate term pay off is the "computers are my competitive hobby" :)

I have been doing things with computers since the 1970's.  

I became a pretty serious electronic bulletin board sysop after the generic Ibm PC became both common and cheaper.

I also am a long-time science fiction reader.

So when the SETI@Home screen saver application came to my attention it was a no-brainer to start using it.

My RAC competitiveness pushed me up the cpu/gpu hill.

One of my major jumps in processing came when all the used/cheap multicore Server Intel cpus hit eBay.

I bought my first Intel server MB with 8 cpu cores and two cpus with hyperthreading. (a 32 thread box).

Later on while still at Seti@Home I experimented with Amd Am4 socket motherboards and managed to actually get something that booted and processed 9 GPUs (a Biostar mining MB). It wasn't reliable though. And stopped working.

Like Seti@Home I have reached the point where I wanted to be competitive "Now" so I sold a pair of RTX 2060 Supers that were not crunching very well on E@H home and started my Radeon journey.

In hindsight, I should have kept the Radeon VII, and bought as many used Rx 5700's as I could imagine at $325 a pop :)

I also jumped onto Rossetta at Home because of the Covid19 pandemic.

Once the vaccines started testing successfully and a Covid19 subproject started at World Community Grid most of my CPU threads have been there while dabbling in other projects.

So at the end of it all, I am a "Sysop".
