OpenCL Magma build issues

Post by aramach4 » Mon Mar 24, 2014 10:14 am

Hello,

I was having trouble with clMAGMA compilation with CL_MAGMA_RT.cpp

I commented out a couple of offending lines which seemed to be error reporting lines:
printf("Error: clGetDeviceIDs at %d in file %s!\n", __LINE__, __FILE__);
printf ("Error: clCreateProgramWithSource at %d in %s\n", __LINE__, __FILE__);

The compilation seems to be clean now - no errors are reported. But make still has exit status 1. And I am able to find only libclmagma.a and not libclmagmablas.a.

I am using ACML 4.4 and clAmdBlas 1.10.321. I see that others in the forum (and the example make file) are referring to clAmdBlas 1.11 - but I can't seem to find where to get that from.

Could you give any pointers to help figure out the compilation problems?

Thank you,
Anand

I don't exactly understand, why did you commented those two lines out? Can you please post the output of make BEFORE you commented out those two lines, and how this changed AFTER commenting out those two lines.

Mark, thanks for the quick response.

Here is the error I got with the original source:-

When I comment out lines 782 and 1041, I do not get these errors, but I still do not have libclmagmablas.a in lib, but only libclmagma.a. I will take back my statement about the exit status of make.

Attaching the make.inc file and both error logs (one without the error messages) to be identified by name.

Thanks,
Anand

The errors still occur, they simply aren't reported to you, which is the purpose of those two print statements.
It appears that for some reason, when compiling, it doesn't find any OpenCL GPU devices.
Can you give some details about your system -- OS, CPU, GPU, AMD APP version -- using clinfo if available. It gives output like below. In particular, you should have a Device Type CL_DEVICE_TYPE_GPU.

I only see CL_DEVICE_TYPE_CPU in your clinfo (that's your Intel Core i5), not CL_DEVICE_TYPE_GPU. Do you have a GPU installed? What kind? For some reason, OpenCL is not seeing it. That needs to be fixed before compiling & installing clMAGMA. There are usually two OpenCL devices in clinfo -- the CPU and the GPU.

Got it. Guess I misread it the last time I posted this.

Thanks much for the responses, I will try to figure these out first.

Best Regards,
