I thought it might be be interesting to someone. Apparently not.

I'm wondering if it generates decent code. I worked on a large multi-cpu system in a past life. These guys out bench marked my old room sized system

You have to provide context. Otherwise everyone is just ??? ;)

The context is I know you do multi-cores or you do Intel Video Synch. Some Nviida chips have 256 cores and have done a teraflop benchmark. I was wondering if that would be useful for transcoding.

The record I was referring to was ASCII Red doing a teraflop when I worked on it at Intel. I have no clue about the software, hence the no comment.

No, they're not useful, and even nVidia gave up on doing video encoding on the GPU cores.

Interesting, thanks. It is supposed to speed up filtering. I guess filtering video frames is a small percentage of the total CPU load.

I also worked on vector processors that filtered seismic data to find oil. So I have had an interest in vector processing for a long time.
