Most extensive VAX MP stress tests I did were on 8-VCPU configuration (i7),
however I also did some testing on 24-VCPU and 32-VCPU configurations. No
problems have been spotted.
If you want to run VAX MP on a 32-bit host system, you might wish to rebuild
VAX MP from source, as 32-bit binaries posted on the web site do not
incorporate some later fixes (I currently do not have 32-bit Linux build
environment around, so I updated only 64-bit binaries).
However be sure to read the note on OpenVMS VAX SMP licensing at the beginning
of "VAX MP User Guide".

Subject: [Simh] Platform for VAX MP Experimentation (amongst other uses)
Hi
I was interested in the collective thoughts of SIMH users with regard to
simulator performance - and in particular - about what would be a suitable
platform to experiment with the multiprocessor variant of SIMH.
I have various reasons to be interested in a server that has multiple cores -
from virtualisation of Windows and other operating systems to running multiple
emulators including VAX and Alpha emulators.
I am seriously considering buying an HP Proliant 585 Gen 6 server - the variant
I'm looking it has 32 GB of RAM and 4 x hex core AMD Opteron 2.4Ghz (8431) for
a total of 24 cores. There isn't a great deal of performance information out
there but I think buying one of these second hand for around GBP 250 is a
sensible compromise between number of CPUs and price.
Are there any other multi-cpu servers I could sensibly consider given budget
constraints? Is 32 GB a sensible amount of RAM or should I got for more?
Thanks for the help.
Mark.
