clAmdBlasTune errors

I tried running clAmdBlasTune, but got strange errors.

Platform: Linux (ubuntu 11.10) 64-bit

clAmdBlas version: 1.6.236

Errors are something along:

/tmp/OCLAlZ3aw.cl(89): warning: variable "ax" was declared but never referenced

              const uint ax = k / 0;

                         ^

3 errors detected in the compilation of "/tmp/OCLAlZ3aw.cl".

Internal error: clc compiler invocation failed.

========================================================

An internal kernel build error occurred!

Re: clAmdBlasTune errors

Hi Rahul~

Thank you for the clinfo dump, that helps to see your system configuration.  We have not had problems before with the Tune program on Linux, so I have no solution to offer you yet. 

Could you provide to me the command line you used to invoke clAmdBlasTune, and could you verify for me what driver and SDK you installed to get CAL 1.4.1664 / OpenCL 1.1 AMD-APP (851.4).

Re: clAmdBlasTune errors

Unfortunately I did not remember what version of driver I had installed earlier. So I just grabbed the latest catalyst (12.3) and tried again

Got the same errors as before. Note that the application does not terminate upon giving an error reported, instead I force terminate it after seeing the error.

New clinfo is attached below.

AMD APP version 2.6

Called clAmdBlasTune from the bin64 folder as follows : "./clAmdBlasTune" with no further parameters.

AMD_CLBLAS_STORAGE_PATH variable is set appropriately (to a folder in my home folder to which i have permission).

One other detail, in case it makes any difference: My monitor is connected to an integrated Radeon 4200, Radeon 5850 is for OpenCL duties

I incorrectly reported my Ubuntu version as 11.10, I am still on 11.04 (64-bit).

Re: clAmdBlasTune errors

I put a Cypress card into my desktop with Ubuntu 11.10 and driver 12.3, AMD SDK 2.6 installed. Unfortunately, I cannot reproduce your problem. You may recompile the whole clBLAS package.
