I've been looking quite a lot for this but couldn't find anything that worked.
I have an Intel Core I5-4430 based system with no extra graphics adapter (so it's using the on-board, integrated Intel Graphics HD that is part of the CPU), running Ubuntu 13.10.
When running BOINC World Community Grid it says "No usable GPUs". When running a bitcoin mining program it says "No OpenCL devices".
I searched the web, found two possible solutions - one was to use the Intel OpenCL driver for Xeon platforms, the other was to use the AMD driver. Tried both. I failed installing the Intel driver as there were too many prerequisites that I just didn't manage to install, and the AMD installation was quite fast to its size (it's 200MB, and took far less than a minute to install), but it didn't solve the problem.
Perhaps I'm looking in the wrong direction here, I'm not sure, but is there anyway I can utilize the advance features of my CPU for those distributed computation programs?
Update
I tried installing the Intel driver again (and failed again), and this is the output of install.sh:
~/Downloads/intel_sdk_for_ocl_applications_xe_2013_r2_runtime_3.1.1.11385_x64$ ./install-cpu.sh
In case of failure please consult README file
rpm: RPM should not be used directly install RPM packages, use Alien instead!

I really don't understand why there are so many missing dependencies. I checked and actually have at least most of them (/bin/sh, for example. really?)
Also it seems there are many duplicates.
Regarding the second line, the one that talks about using Alien, well I did use alien to convert this package, including scripts, then tried installing using Ubuntu's package manager, but it also failed on missing dependencies.
Any ideas? What am I doing wrong?
Update 2
Following hbdgaf's link I followed the selected answer instructions and these are my outputs:
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
$ ./capsbasic

*** Detailed information for each device ***
So apparently I need a different driver, but where do I find it? Seems the official drivers by Intel are not built for Linux.
