"Dropped by adjacent node" ....

In your eyes the bridge program between two nodes, communicating via psilo, would be preferred to one reliable PtP link between the same two nodes? No. Direct links are almost always preferrable. But you scenario would be equally well solved using 3,4,5 as costs. Using 10,20,30 makes several hops over ptp links be preferred over the (one or) two hops on the bridge. I'd say that the one or two hops on the bridge is better than two ptp links, and might be as good as one hop on a ptp link as well. Johnny

RT-11 DECnet?

How much work would a limited phase 4 endnode implementation be? Limited : FAL only, no hone, cterm etc. Verzonden vanaf mijn BlackBerry 10-smartphone.

Parallel computing using DECnet

by jeep＠scshome.net

The DEC calling standards and the design of DECnet do not limit us to using only one language. Each system could use what ever is available on that system (and what the user knows how to program in) and use DECnet objects to pass information back and forth. A simple protocol (if you will) could be spec'd out and implemented for any of the languages. A common language could be used for the "glue". MACRO-11 might be fun - it could easily manage the differences between BASIC and FORTRAN (and others) calling sequences (ie R5). -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Dave McGuire Sent: Thursday, May 01, 2014 23:59 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Parallel computing using DECnet On 05/01/2014 11:41 PM, Jovan Trujillo wrote: Oh man ha ha so we are going to do amazing things with 64kb.

Alright fractals sound like a good first project for something like this. ...we do have 64kb available right? :) There are very few PDP-11s that won't kick the living snot out of a Commodore 64, FYI. But using FORTRAN, we could potentially use overlays and such. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

QBUS sound [Was: Re: [HECnet] Parallel computing using DECnet]

by jeep＠scshome.net

My Pro-380 has built-in color (and graphics). Sound would be possible using the TMS-11 - I have one of those as well... -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Dave McGuire Sent: Friday, May 02, 2014 02:10 To: hecnet at Update.UU.SE Subject: Re: QBUS sound [Was: Re: [HECnet] Parallel computing using DECnet] On 05/02/2014 02:05 AM, Pontus Pihlgren wrote: There are very few PDP-11s that won't kick the living snot out of a Commodore 64, FYI. I've yet to see a PDP-11 with builtin color graphics _and_ sound. Me neither. The 64 probably outsold all models of 11 taken together. That's certainly possible, but one cannot argue that their target markets were even remotely related. Or even aware of each other's existence, for tha tmatter. so it depends on your application and measurement I suppose. We were talking about distributed math apps. I'm told there were, probably third party, sound cards for qbus. Has anyone of you seen one or know more? I haven't. I have a really neat Qbus card with a TMS9918 sprite-based video chip on it, though! -Dave -- Dave McGuire, AK4HZ New Kensington, PA
