Queueing Models of machines with partitions and/or ccNUMA?

[Mott Given]

Does anyone know of any software packages which can automatically read the HP-UX OS to automatically model applications in partitions and/or ccNUMA (cache coherent Non-Uniform Memory Architecture) servers in queueing models built for capacity planning?

Hi Mott,

I personally don't know of any software that can do this, but I've worked with someone who knows a great deal about ccNUMA and the queuing models associated with the HP-UX scheduler. This person spent a number of years working in the Capacity Planning Center in Cupertino, so he may know of some software that can do this.

My suggestion is that you contact HP Support and ask them to check with the Capacity Planning Centers to see if they have any software, or know of any software, that can do the type of thing you're looking for.

Regards,

Dave

Now with the option to have cell local memory and/or cell interleaved memory, it gets even more complicated. I would be very surprised if you found a tool that could do all that you ask automatically. HP-UX has tools for processor affinity, gang scheduling, etc. The mpsched and mpctl command might be something to investigate, as mpctl system call can return information on the number of processors or locality domains configured in the system. The book by Robert F. Sauers on "hp-ux 11i tuning and perfomance" might help. I presume you have looked at your application with Caliper.
