    Cannot run samples in AMDAPP sdk with A10 5800K - Linux - SOLVED

    kbentley57

      I'm trying to learn the OpenCL language with C++, and I'm having a little trouble getting started.  I've purchased a machine to start developing natively on, with an A10 5800K as the APU.  I've downloaded the latest AMDAPP sdk,  and have installed the drivers in Ubuntu's repos. (more on my software later down).  I first had issues compiling the samples, but I sorted that out with another post, adding #include <unist.h> in the samples/opencl/SDKUtil/include/SDKCommon.hpp file.  I'm now able to compile the samples, and I can run clinfo, as well as HelloCL.  The output are below:

      It appears that everything is installed correctly.  However, when I try to run any other sample, I get an error; here is some output of two of the compiled examples:

      I'm guessing I'm running out of memory, or at least that is what the error code would lead me to believe.  I'm sure that I have enough free memory in the system to run these programs, so there must be something else software related causing the error.

          I think I may have found the solution to my problem.  In the BIOS, the amount of shared video memory was set to auto, and I had assumed it could be allocated on demand.  I'm still not sure if this is the case.  I changed the amount of shared memory to 512 MB, the max setting, and I was able to run all of the sample programs successfully.  That leads me to another question though; how much system ram can an APU allocate to the GPU?  I was under the assumption it could let it have all the RAM it wanted, but perhaps my motherboard is limiting me to 512 MB?

           

          EDIT:  It turns out that I was running an early BIOS.  There was an updated BIOS released by AsRock just a few days ago that sets the correct limit to 2 GB.  Everything seems to be running fine now.  Marking as solved.
