hyperthreads on rx4640

Martha Mueller — Mon, 16 May 2011 19:17:44 GMT

I have an rx4640 running HP-UX 11.23. I wanted to know if this server could run hyperthreads if I upgrade the OS to HP-UX 11.31.

This server has two single core Itanium 2 processors, A9732A. I think they are the "Madison" version, not Monticeto. I have read that hyperthreads can run on Itanium 2 processors, but I have also read that they started with Itanium 2 Monticeto.

Does anyone have an answer?

Thanks

Hi,

Yes, you need Montecito for HT, Madison is single thread.

My server won't be able to use hyperthreads, the processor is too old.
