Quick report on my new AP OpenCL endeavor. For now I've completed 4 task. One is validated, the other three are Validation inconclusive. I don't actually know what that means, but - you know what they say about three being a trend - I decided to post here anyway. Do you think inconclusive validation might have something to do with the app being beta?

[edit]One CPU core continues to be fully occupied and as far as I can tell there is no blanking involved. Can someone tell me where on the Intel forums should I post about this and how do I define the problem? A link to a relevant thread would be welcome.

GPU-Z reports over 90% usage, so the GPU is doing something. Furthermore the task is at 25% after ~1hour, with an estimated remaining at 11hours. 25% per hour and 11 hours estimation amount to about 7 hours difference which I take it might be some artifact suggesting that the GPU is indeed working and producing stuff.

As for the blanking, I do not know how to do that :/

Do you think it is worth it spending a CPU core to GPU app or I should just load the CPU core with CPU app and forget about the Intel GPU? I'm having trouble comparing the two...

I just added this to my app_info.xml

And started receiving AP tasks.
Next, from event log:

5/22/2013 6:03:18 PM | SETI@home | Starting task ap_02jn10aa_B1_P0_00195_20130522_19949.wu_1 using astropulse_v6 version 604 (opencl_intel_100) in slot 1

Which I gathered to mean that I now crunch on the Intel GPU. This is confirmed by the Tasks tabsheet, which says "Running (0.04 CPUs + 1 intel_gpu GPU)".

The problem is that I have a process AP6_win_x86_SSE2_OpenCL_Intel_r1764.exe which uses a CPU core at 100%. So I'm guessing it works on the CPU, and not on the GPU.

Can someone help me with this? I want to use the GPU only.

Here is my full App_info.xml

I guess I took some shortcuts explaining. I know what the file is called, where it is placed and how it should properly be formatted. I just used shorthand assuming you'd figure out what my background is. A bit of a boneheaded decision on my part, sorry about that...

Anyway. I think everything is ok, formattingwise, with my app_info.xml. I guess I could have mucked up the content. Bellow is a link to the xml, just in case. In it there are only two app. The CUDA and IntelGPU openCL ones.

Let me use this thread for an inquiry. So, I'm trying to test the Intel GPU app from Raistmer.

This is the appinfo i gathered to be needed:

<app>
<name>astropulse_v6</name>
</app>

<file_name>ap_cmdline_win_x86_SSE2_OpenCL_Intel.txt</file_name>
<open_name>ap_cmdline.txt</open_name>
</file_ref>
</app_version>

The problem is that I have not seen a single work unit send for this app. What might be the problem?

The machine I'm trying to use this on is a Dell Inspiron 5720 laptop with two GPUs. The 630m calculates CUDA ok, but no OpenCL via Intel GPU(HD Graphics 4000). Could it be that they can not work at the same time? Or could it be that there are no work units? If not, can you point me to a direction where I could go to try and diagnose the problem?

What I'm looking for is the two GPUs working together.

To recap. Even though BOINC now detects Intel gpu's OpenCL the Seti@Home project still does not have an app that can use it. To use it I would have to tinker with a third party beta app (the one from Raistmer). Since I don't have the time and inclination I should probably just wait for BOINC to just download and start using the OpenCL app once Seti@Home project comes around to making it available.

Is that about right?

Hi,

I just found out that new version of BOINC has support for OpenCL on Intel GPU's. I installed the new version, got the OpenCL detected, but I do not see what I expected to see - namely a process for each CPU core + another process utilizing the GPU(via OpenCL) - as the CUDA BOINCs I have running.

Why is that?

I guess I'm missing something... Could it be that the CPU applications use OpenCL if available? That would mean that I should see a spike in the computers RAC, right?

OS is 64bit Windows 7, CPU is i5-3470, GPU is HD Graphics 2500 (1624MB).

Thanks!

P.S. I had some lunatics custom apps installed but I removed them. As far as I can tell BOInC is working with its own set of calculators.

Hi,

I have a number of Intel Ivy Bridge, OpenCL enabled, integrated graphics cards that sit idle. Is there a way to harness them? If not, has anyone heard of something being done on that front?

Thanks!

I cannot download the installer for the optimised apps. What is up with that? I would really like to update a couple of clients but do not have the time to do it manually.

I can't ask in their forums as the registration is disabled?

Here is a screenshot of the download screen.
