Hyperthreading usable in Xpress Pro HD???

[Oakmozart]

Hyperthreading is not officially supported for Xpress Pro HD (or any other Avid NLE software that I know of). It WILL run on computers that have hyperthreading enabled, but HT makes the Avid system unstable/unreliable…ESPECIALLY if you have DNA hardware hooked up to it.

Hopefully this will be resolved in near-future releases of Avid software.

Actually, if you have a single CPU setup, Avid recommends using HT. It a slight affect on render times.
For dual Xeon systems, it should be disabled.

Where does it say that? I’ve never heard it said from anyone at Avid. Even the ACSR’s have told me to immediately disable it…even on a single-chip P4 w/hyperthreading. I’d appreciate a link to investigate this further.

This often discussed in the Avid Xpress Pro forum.

[check the links inside the threads also].

FYI – Brian Williams is one of the Avid engineers.

I can confirm HT does benefit single CPU P4 systems. A very long cross dissolve would take me 22 seconds to render without HT and about 18.5 with it on.

Oh yes, I’m very familiar with Mr. Williams…from what I’ve seen, he’s a great guy.

Thanks for the links. Interesting that I missed it on Avid’s forums. I’ll investigate further.

Thanks.
