Hi All,
I found out something important about running PARIS on a multicore machine
this morning.
All devices that share an IRQ with PARIS also need to be locked to the highest
CPU using the intfilter driver.
I guess my new motherboard has more "stuff" on it, and one of my UAD cards
now shares an IRQ with PARIS. Paris was not detecting an interface on the
master card after I finished installing all my drivers. Locking the UAD
cards to the highest CPU fixed it right up.
Cheers!
Mike

So, does that mean that the native power the UAD-1 cards need won't load down
the Paris processor?

Hi Gantt,
Yes and no. If you manually assign the two drivers to different CPUs, the
interrupts wil be handled by the two different CPUs.
What I hadn't considered before staring on the Scherzo is that the driver
is often called by an application, and when an application calls a driver,
the driver will run on the CPU that the application is running on, regardless
of interupt affinity settings. That's why the PARIS app needs to be locked
to one CPU, too.
So, if the UAD driver is set to a different CPU than PARIS, calls that PARIS
makes to the UAD driver will run on the PARIS CPU, and replies made by the
UAD cards will run on the UAD CPU.
I hope this helps.

Then you're ready for SQL Server 2008 utilizing HyperV.
