Cannot co-exist with OpenCL driver

[syifan]

The HSA kfd driver works on radeon driver but opencl driver works on fglrx driver. This two drivers cannot co-exist on one machine. Can I still run OpenCL program on an machine where HSA is installed?

Not with fglrx.
But you can use CLOC - the offline cl compiler - to convert your OpenCL code to HSAIL and then run it over the HSA runtime.

Hello Oded,

What is the recommended way to run HSAIL code on the HSA runtime.

Currently, I am trying to run HSAIL code on the HSA runtime provided with
HSA-Runtime-AMD.
Note the vector_copy sample appears to be running successfully on my
machine.

(Should we be using the runtime in HSA-Runtime-Reference-Source?)

I seeking to run the HSAIL for another application in the same manner as
the vector_copy sample.
One problem I see is a mismatch in HSAIL version between what the CLOC
compiler is generating, and what the HSAIL looks like for the vector_copy
sample. This is invoking CLOC using the HSAIL compiler in HSAIL-HLC-Stable.

Should we be using with CLOC an HSAIL compiler built from
HSAIL-HLC-Development?
I am trying that, but the llvm-link step is failing.

Thanks,
Rick

Hi Rick

The CLOC master branch is not up to date. Please find CLOC-0.9 branch. It can compile OpenCL program with HSA host without problem. However, I cannot compare HSA with OpenCL on the same machine, since the driver does not compatible with each other.

Hi Rick,

Also, you can use either the runtime from the reference source or from the binary release. Again, CLOC-0.9 is the up to date branch.

Hello Oded, Yifan, Adrian,

Yifun: Thanks. I used CLOC-0.9, which generates code acceptable to the
runtime (1.0f)

Adrian: I am glad to know that the compiled runtime can be used in place of
the distributed binary. I haven't tried it yet, but plan to.
Also, thanks for your tips on another thread re: setup of the runtime and
kernel driver. I am running all tests that I have found without issue.

I should have replied earlier. Positive feedback is important!

Thanks,
Rick
