ck-set-cpu-performance. command not found error when running ck crowdtune

[guillon]

After installing ck crowdtuning with: $ git clone http://github.com/ctuning/ck $ PATH=$PWD/ckbin:$PATH $ ck pull repo:ck-crowdtuning

When running: $ ck crowdtune program --gcc

The exepriments goes to completion, but apparently some tools are missing and in particular frequency settings end up to be skipped apparently.

ck does not find apparently these programs:

• ck-print-gpu-freq
• ck-set-gpu-performance
• ck-set-cpu-performance

I get these messages in the output: ... GPU name: NVIDIA Corporation G98 [Quadro NVS 295](rev a1) GPU vendor: NVIDIA Trying to read GPU frequency: ck-print-gpu-freq >/tmp/tmp-ck-Qlb8TQ sh: ck-print-gpu-freq: command not found

Hi Christophe, Thanks for reporting. Yes, I confirm that we need to improve it:

• turn off CPU/GPU freq setting by default
• improve platform detection and select specific scripts to do CPU/GPU freq scaling So, I keep this ticket open...
