We are developing a system in which we need high performance communication between two MicroVAXs, one running VMS and the other Unix. The ideal approach, because of minimum software development and overhead and maximum performance, would be some type of shared memory. An alternative approach would be to use parallel ports. The following questions all relate to this communication issue: - We have a pair of Ranyan shared memory cards, but have been unable to get them to function properly, and have gotten grossly inadequate support from Ranyan. Has anyone experience with the Ranyan product? Has anyone gotten them to work under VMS? Under Unix? - Does anyone know of any competitive shared-memory products? Sources? - We have DRV11-WA parallel interfaces, and there is a driver in VMS that is designed to work with it, but under VMS 4.3 it doesn't work because DEC modified the design of the DRV11-WA hardware and the software folks haven't caught up. Does the driver work under VMS 4.4 or 4.5? Anybody know when/if it will be fixed? - Anybody have Unix drivers for DRV11-WA, DRV11-J or even plain DRV11 boards? - Recommendations on high-performance parallel interface cards, preferably with on-board buffering? Sources? Drivers? - Other suggestions? Thanks for any assistance you can give. Bruce Bon Bon@JPL-VLSI.ARPA
