Topic 197528

There's a new app version 1.06 of the S6CasA search. For the first time (in years), we will run the Beta test on Einstein@Home (instead of Albert). To participate in this (and future) Bete test, please set "Run beta/test application versions?" in your Einstein@Home preferences to "yes".

This App version reserves the last 1% of progress for the last step that we thought to take only minutes (toplist parameter reconstruction), but on some computers apparently leads to tasks sticking at 100% for hours with no apparent progress.

As you may have noticed from the Applications page, there will also be an OpenCL (GPU) version for this application later, but that will be a separate announcement. In any case this will also require you to set "run Beta test app versions" in your preferences.

Gravitational Wave S6 Directed Search (CasA) v. 1.06 Beta Test

Hi Bernd.

The (ALTIVEC-Beta) version is listed on the Applications page as running "on Intel".

Well spotted! Fixed. Yep,

Well spotted! Fixed. Yep, also a Beta test for our Beta test...

I tried to get 1.06 Beta

I tried to get 1.06 Beta work, But the scheduler sent me the v1.05 (X64) app and work:

http://einsteinathome.org/host/10224316/tasks

The host is on the work venue, the work venue only has Use CPU, CasA, Run beta/test application versions, and Run CPU versions of applications for which GPU versions are available selected to 'yes'.

O.K, i have a v1.06 (X64-Beta) task now, took a couple of scheduler contacts to get it through, But i'm on a relatively poor WiFi connection through a public hotspot so that is probably the reason,

How much of an improvement do you guys think the GPU GW application is over the CPU app?

Are we talking 2-3 times faster, or an order of magnitude?

Depends on your card, a bit

Depends on your card, a bit on double precision performance and a lot on GPU memory bandwidth. I saw it doing an ordinary S6CasA task in about 1000s on an ATI 6970.

So about 3x faster on average

So about 3x faster on average compared to my i7 4771...

Not bad.

And I'm assuming these will run on iGPUs?

You run a S6CasA task in less than an hour (3600s)?

Yes. According to you it

Yes.

According to you it takes about 1000s to complete one GW unit on a 6970, and on my 4771, it takes 24000s to complete a unit *per thread*, meaning on average I compute one unit every 3000s (24000s/8 cores).
