I believe that on the Balance system, the SLIC interface was used to select the processor currently running the lowest priority process. What is done on the newer machines? In addition, if you happen to know how other multiprocessors systems besides the Symmetry (for example Alliants) select the processor to handle an interrupt, I would appreciate hearing about that too. Any references would also be appreciated. thanks, --george Internet: bier@cs.wisc.edu UUCP: ...!{harvard,seismo,topaz,akgua,allegra,usbvax}!uwvax!bier
