[Discuss-gnuradio] How to set up MP-Benchmark Test PowerPC Processors (using Altivec)

I want to set up several Benchmark Tests for PowerPC Processors using Altivec.
The MP-Scheduler Benchmark works for Core2 Duo and on PS3 (without Altivec) fine.

But how can i set up the Benchmark for PowerPC Processors (e.g. Cell BE) using the Altivec Extensions?
There are no options given to use Altivec, or is there a special benchmark-code?

Best regards
Matthias
