clAmdBlasTune - 2nd card & options?

I have multiple AMD Radeons in the machine, one is cypress and other is tahiti. I started running clAmdBlasTune and it appears it is only tuning for first card. How can I tune for tahiti which is the 2nd card?

 

What is the purpose of --store-kernel option exactly? What does storing kernel help?

 

Does it tune based purely on the execution performance or the PCIe bus speed (8x vs 16x) would effect the results of tuning?

 

Does the .kdb file gets used by the library always automatically when AMD_CLBLAS_STORAGE_PATH is set?

 

Thanks,

Evren
