[Simh] Platform for VAX MP Experimentation (amongst other uses)

[Sergey Oboguev]

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".

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.
