In my case, gcc with the default makefile. I don't use VC (or the OS it runs on) unless serious force is applied...

How was simh compiled? I used Visual C and the difference between running the compiler with optimization on or off made quite a difference for the generated code. And gcc might compile even faster codefiles.

Why is SIMH so slow though?
As far as I can understand, one MIPS is roughly one VUPS, correct?
So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?
Are the architectures that different (obviously they are) or what is it?

I've set up the bridge to start at boot on an OpenBSD machine and I am having some issues getting anything into a log file.
I start it like this:
/var/bridge/bridge -p 4711 -d /var/bridge/ > /var/bridge/bridge.log 2>&1 &
but bridge.log is always empty. At start, after sending SIGUSR1, etc.
Thoughts?

That's a pity, because I've always wanted to know whether the same trick would apply. The white box trick worked for me on the 3300 and a couple of 5305's. A 7305 owner in Germany made it work too. The DS20L is a different beast, right? Enough not too spend money on it. Hans

If the "fiddling" is similar to what is necessary to run VMS on the white box alphas then have a look at

The white box alphas were tergeted at the WNT market. Adding two srm parameters works wonders for VMS. It does not involve hardware mods and AFAIK the mods are completely reversible.

Sent from my cell phone which will undoubtedly upset some systems. Sorry, I'm 600 kms from home.
Yeah, I don't know. I've got a white box AS1200 (aka 5305) that I
twiddled to run VMS on and I know how that works. All I ever saw was a
vague reference on comp.os.vms once about the DS20L. I was never able
to acquire one so I didn't pursue the issue.

Dave did the Alpha family come in a 1U size?
Yes, the DS10L comes to mind. My HECnet node AXPEE:: is one of those.
They are EV6-based (nice and quick!) and are available clocked at
466MHz and 600MHz.
There are other 1U models, but that's the one I'm most familiar with.
If so could said system be considered to be a quiet one?
Eh, so-so.
From DEC, there was only the DS10L, in two processor speeds as Dave
mentioned, and the DS20L which was an 833MHz processor system in the 1U
size. The DS10L was supported for use with any of the DEC O/S while the
DS20L was only supported for Tru64 from DEC and Linux. VMS was not a
supported O/S, although it was purported to be possible to get it to
boot with some fiddling. Unfortunately, I was never privy to the
details of such.

Alpha Processors Inc (API) also produced a 1U system. Based on the
DS20L platform, they aimed for the HPC cluster market. Also purported
to be possible to boot VMS with some fiddling, but the usual O/S was
some form of Linux. http://youtu.be/RfowtlIk9Uc
All were fairly noisy for their size. Maybe not noticeable in a
computer center, but definitely in a home setting.

Brian, could you verify that you have the latest version? I did some work to try and get rid of warnings a while back, and even though I'm sure some issues might be because of 64 bit issues, I would have expected some of the warnings you reported to have been fixed already...

With Multinet you can run DECnet over TCP in the same

Yes, you are incorrect. There is nothing that requires an area here, and it just means you need to deal with a full blown DECnet stack, instead of a simpler endnode.
It might be worth understanding that there is nothing technical added by going to multiple areas. It is just a complication which allows you to have more nodes, but at the cost of more complex routing.
Even within one area, you can have a large number of hops between nodes. Makes no difference to DECnet. The rules for the topological layout is simple:
1. End-nodes needs to be adjacent to atleast one level 1 router.
2. All level 1 routers in an area must be able to talk with all other level 1 routers. And only level 1 routers route messages within an area, which means you cannot have an endnode in the chain.
The layout can be a star, a ring, a line, a combination, hybrid, or whatever. There are absolutely no topology that you can't have.
The type of links can also be anything. Ethernet, multidrop, point-to-point, or something weird. Makes no difference.
Ok, my bad, misunderstood the UDP Mutlinet tunnels :)
Drop that node and add DEB390 with the address 52.600 when you get the chance.

2. I'll run MULTINET on both the Debian S/390 and the host
And? Another area makes no difference for this. (I thought Multinet was a TCP/IP stack in VMS... :-) )
