Package: boinc-client
Version: 7.4.23+dfsg-1exp3
Severity: normal

Dear Maintainer,

current version fails to detect Intel GPU as an OpenCL device.

I have several OpenCL icd files installed:
dpkg -S OpenCL/vendors
pocl-opencl-icd: /etc/OpenCL/vendors/pocl.icd
pocl-opencl-icd, beignet: /etc/OpenCL/vendors
beignet: /etc/OpenCL/vendors/intel.icd
beignet: /etc/OpenCL/vendors/intel-beignet.icd

and clinfo detects 3 platforms:
clinfo -h
pocl warning: encountered incomplete implementation in clGetDeviceInfo.c:225
pocl warning: encountered incomplete implementation in clGetDeviceInfo.c:271
Number of platforms:                             3
with one being:
  Platform Name:                                 Intel Gen OCL Driver
Number of devices:                               1
  Device Type:                                   CL_DEVICE_TYPE_GPU

But boinc reports:
13-Nov-2014 22:44:07 [---] No usable GPUs found

Thanks for the help

-- Package-specific info:
-- Contents of /etc/default/boinc-client:
# This file is /etc/default/boinc-client, it is a configuration file for the
# /etc/init.d/boinc-client init script.

# Set this to 1 to enable and to 0 to disable the init script.

# Set this to 1 to enable advanced scheduling of the BOINC core client and
# all its sub-processes (reduces the impact of BOINC on the system's
# performance).

# The BOINC core client will be started with the permissions of this user.

# This is the data directory of the BOINC core client.

# This is the location of the BOINC core client, that the init script uses.
# If you do not want to use the client program provided by the boinc-client
# package, you can specify here an alternative client program.

# Here you can specify additional options to pass to the BOINC core client.
# Type 'boinc --help' or 'man boinc' for a full summary of allowed options.

# Scheduling options

# Set SCHEDULE="0" if prefering to run with upstream default priority
# settings.

# Nice levels. When systems are truly busy, e.g. because of too many active
# scientific applications started by the boinc client, there is a chance for
# the boinc client not to be granted sufficient opportunity to check for
# scientific applications to be alive and make the (wrong) decision to
# terminate the scientific app. This is particularly an issue with many
# apps started in parallel on modern multi-core systems and extra overheads
# for the download and uploads of files with the project servers. Another
# concern is the latency for scientific applications to communicate with the
# graphics card, which should be low. All such values should be set and
# controled from within the BOINC client. The Debian init script also sets
# extra constrains via chrt on real time performance and via ionice on 
# I/O performance, which is beyond the regular BOINC client. It then was
# too easy to use that code to also constrain minimal nice levels. We still
# think about how to best distinguish GPU applications from regular apps.
#BOINC_NICE_APP_GPU=5        # not yet used
