I'd like to use OpenCL on the CPU of a large supercomputer with AMD Opteron running a Red Hat OS that meets the installation requirements.  I do not have admin access to the machine.  Also, support for a system-wide install has been lacking motivation.

So, is it possible to install the APP SDK at a user level?

Why is sudo access needed?     For registration of the ICD? 

Is there a workaround for CPU-only OpenCL?

Thanks.

You need administrative previlages to install APP SDK...

Sudo Access does the following

1. Registers the ICD

2. Globally sets the environmental variables.

3. Installs the Linux APP SDK developer and sample files.

4. Installs the Linux APP SDK CPU runtime files.

you can set OPENCL_VENDOR_PATH enviroment variable to override default /etc/OpenCL/vendors path where it search ICD files. then you just need extract AMD SDK manualy and set LD_LIBRARY_PATH to amd_app/lib/x86_64/
