[comp.sys.transputer] HELIOS measurements

vollmer@gmdka.UUCP (Juergen Vollmer) (02/15/90)

I'm looking for information about measurements of the helios operating 
system running on T800 / T414 concerning 
- communication speed over external links to neighbour and non-neighbour 
  Transputers (message length: 1/4/8/10/100/1000 .. bytes);
- concerning communication speed over internal channels;
- time for starting new tasks.

Are there comparable numbers for systems not using helios 
(other operating systems, no operating system on Transputer)?

Please email, I'll summarize.

Thank's
