Yes, I know. I've tried them all.
But for the injection run there is no checkbox yet.

I see that now, sorry.

*sigh*

Always the same. Takes mostly weeks/months until new apps are "free" for everyone. Wonder how long it will take this time... :-\

Continuous Gravitational Wave

Continuous Gravitational Wave search O2 All-Sky

Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU 1.02 (GW-opencl-nvidia) (beta test)

Nvidia GTX 960, crunching 1x ... a task completed in 7 h 25 min

Earlier today Bernd posted a notice reading "We completed our GPU port of the GW app such that it can now also process the current O2AS tasks efficiently. There is now a GPU version of the O2AS20-500 app available for Beta testing."

I tried enabling both

       Beta Testing|Run test applications
and Applications: Continuous Gravitational Wave search O2 All-Sky

on the location-specific Einstein project preferences for one of my hosts.  It promptly downloaded a task, and I suspended all other work so that it started up immediately.

That task did not run what I would term "efficiently".

In particular, while it used nearly a full CPU, the GPU usage was very low (intermittent but averaging far under 10%).

I kept some watch using task properties and did see that it began saving checkpoints after a couple of minutes.  After an initial period of "fake progress," it settled down to a pattern which suggested it would take a number of hours to complete.

This seemed very like the most recent flavor of Einstein GW work I ran a number of weeks ago, not like an "efficient" performance-enhanced variant.  I confess that I aborted it after about 2/3 of an hour of running time with reported progress well under 10%.

Just possibly the task I got was not of the newest flavor.

The task name was: h1_0510.25_O2C02Cl1In0__O2AS20-500_510.40Hz_616_0

Application name was: Continuous Gravitational Wave search O2 All-Sky v1.02 (GW-opencl-ati) windows_x86_64

The host runs under Windows 10, using an AMD RX 570 graphics GPU, with a very modern, but not especially fast Intel CPU (i5-9400F) with several spare real cores.

Perhaps the real, new, beta-test one is different from this one.  Does anyone know?

The previous chat here was about the Injection app vs O2 app mentioned in the other thread. Neither seem to work.

Bernd seems a bit perplexed by this particular turn of events.Surprised

Cheers,

What the point of having GPU

What's the point of having GPU applications if that only uses 10% of the GPU ? My GPUs don't even switch to boost clocks, I feel like I'm wasting resources ...

Version 1.03 is clearly

Version 1.03 is clearly better than the previous ones.

Version 1.04 is significantly

Version 1.04 is significantly faster than 1.03 yesterday.
