[Simh] Use muliprocessor with SIMH

[Broer van Smeden]

Dear Micheal,
Please to hear that so many openVMS system are still running.
However I wonder why you are not running multiple applications together on
alpha servers. The migration (depending on which kind of applications) is in
many times simple and you will get a great performance and it is good to
rebuild your application and cleanup the mess for all years.
Probably you can run this with two AXP DS20E, which can be bought
refurbished. In this case only 2 systems needs to be maintained.
I used SIMH for the migration for replacement of some VAX marcro functions
to C variants. Also we checked the charon VAX emulator.

Kind regard
Broer

Hi, 

we migrated our complete VMS-VAX-hardware (microVAX 3100/95, 3100/98)
including our production-systems to SIMH from 02/2005 to 08/2005, in all 47
nodes....

SIMH works pretty good in daily business (all-in-one/ACMS/RdB-applications)
with uptimes up to 300 days...

Kind Regards,
