There seems to be some minor problems with clAmdBlasTune

1- Something funny at help:

Used data types:
   --float
       Single float version of functions.
   --complex
       Double float version of functions.
   --double
       Single complex float version of functions.
   --double-complex
       Double complex float version of functions

2- --store-kernel is not functioning?

# clAmdBlasTune --store-kernel
Unknown argument --store-kerne

3- Fails: on AMD Radeon H 6320 Graphics (cliinfo output attached)

# clAmdBlasTune
GEMV is being tuned, progress: 0.07% clEnqueueNDRangeKernel() failed with -5(CL_OUT_OF_RESOURCES

Yes, we are able to reproduce this issue, but can't say much else right now.

For your DGEMM performance, you should be able to get around 600 Gflops for a matrix of size 2Kx2K on Tahiti.

I've heard several request for downloadable tuning databases, but it wasn't something we were planning on distributing. In concept, we would want each individual user to generate their own tuning files for their own computer, as each individual computer has their own configuration. For now, there are no plans to distribute tuning files, but i will make a note of it in our tracker for possible future consideration.
