Hi,
I ve read talks on this group about testing drivers on multiprocessors.
What is a cheap workstation class dualprocessor machine that can be used for
driver testing?
k
I use a dual Athlon system with 3 gig RAM and 500 gig HD space. I chose the
Tyan Thunder K7 MOBO, but I think they now make the K8. I got the MOBO
loaded so that I could test all sorts of configurations. I use VMWare on
this system and it flies. The MOBO also has dual ethernet ports, dual IDE
controllers and dual adaptec 160 SCSI controllers. I think I paid 500 USD
for the MOBO about three years ago. It was a worthy investment.

Any machine with HyperThreading will suite, if you’re limited in bugdet.

feel free to state this is part of an older thread, but what exactly are we
testing in a driver that requires multiprocessor support. can somebody
elaborate on this. and why does HT suffice for the same?

Well the reason you need a multiprocessor is that most multi-threading
issues cannot be seen on a uniprocessor system. Actually, the rule of thumb
is the more processors the better, since you are more likely to see the bugs
on say an 8-way than a 2-way.
Now since hyper-threading simultes two processors with one cpu, it provides
most of the capabilities of a dual processor system. Most in the sense that
some internal scheduling inside the cpu, means that is it is not as good as
a true MP, but close.
Personally, if I were buying a system these days I would look at a dual
x86-64 (i.e. Opteron or EMT64) since then you can test 32-bit and 64-bit
versions of your driver.

HT is multiprocessor software-wise.

For a start, lets say you have some code that accesses shared resources
(very common in drivers) How do you know it will work well on a MP
machine ?
