I have not much experiences with Einstein.

Until before yesterday I had unchecked the thread title question.
Since yesterday I have it checked.

I have (inter alia) an Intel Celeron J1900 CPU with iGPU ('Intel HD Graphics' (without a number ;-) ) and NV GT730.

With the:
Binary Radio Pulsar Search (Arecibo) v1.34 (opencl-intel_gpu-new)
windows_x86_64
- app the WUs lasts around 1 hour (on the Intel HD Graphics).

Then with the:
Binary Radio Pulsar Search (Arecibo) v1.34 (opencl-intel_gpu-Beta)
windows_x86_64
- app the WUs lasts 1 hour and 30 minutes (on the Intel HD Graphics).

Now with the:
Binary Radio Pulsar Search (Arecibo) v1.34 (opencl-intel_gpu-new)
windows_x86_64
- app the WUs lasts 1 hour and 30 minutes also (on the Intel HD Graphics)?

In past with the 'new' app the GPU Load was continuously over ~ 95 %.
After with the 'beta' and with the 'new' the GPU Load is just jumping between ~ 60 - 80 %.

Is this because something is broken now, or this is just because of the currently available WUs?

All Binary Radio Pulsar Search (Arecibo) tasks for computer 12298250:
http://einsteinathome.org/host/12298250/tasks&offset=0&show_names=0&state=0&appid=19

(In both cases the apps use ~ 400 MB system RAM.
BOINC say the Intel HD Graphics have 1304 MB.
In BIOS I set 'use max possible', in Windows 8.1's Task-Manager it say 554 MB reserved for hardware.
So in real the GPU have just ~ 512 MB 'VRAM'?
So 2 WUs/GPU aren't possible, because not ~ 800 MB available?)

If I looked correct, my PC could get the following apps:
http://einstein.phys.uwm.edu/apps.php

Binary Radio Pulsar Search (Arecibo) - BRP4
i-1.34 (opencl-intel_gpu)
i-1.34 (opencl-intel_gpu-new)
i-b-1.34 (opencl-intel_gpu-Beta)

Binary Radio Pulsar Search (Parkes PMPS XT)
c-1.52 (BRP6-cuda32-nv301)
c-b-1.57 (BRP6-Beta-cuda55)
i-b-1.52 (BRP6-Beta-opencl-intel_gpu)

Binary Radio Pulsar Search (Arecibo, GPU)
c-1.39 (BRP4G-cuda32-nv301)
c-b-1.52 (BRP4G-Beta-cuda32-nv301)
i-b-1.52 (BRP4G-Beta-opencl-intel_gpu)

[i = Intel, c = CUDA (NV), b = beta]

If the thread title is checked, my PC get just the follwing (beta) apps?

Binary Radio Pulsar Search (Arecibo) - BRP4
i-b-1.34 (opencl-intel_gpu-Beta)

Binary Radio Pulsar Search (Parkes PMPS XT)
c-b-1.57 (BRP6-Beta-cuda55)
i-b-1.52 (BRP6-Beta-opencl-intel_gpu)

Binary Radio Pulsar Search (Arecibo, GPU)
c-b-1.52 (BRP4G-Beta-cuda32-nv301)
i-b-1.52 (BRP4G-Beta-opencl-intel_gpu)

(BTW. AFAIK, Einstein have the Beta-Project Albert, there the apps will be tested before they are released here? So the Beta apps at Einstein aren't buggy and should run smoothly?)

Thanks.
