Systems may be configured with as many as 63 function cards, each including 1 88100, 2 or 3 88200 CMMUs, and 16 Mb of physical memory. Each function card also includes a full VMEbus interface for I/O. Systems with over 120 processors will be available in the near future. Since representatives of Encore and Harris have described their current and planned realtime systems in response to your question, I would like to mention that the TC2000 also has powerful realtime capabilities. The TC2000 may be configured to run TC2000 nX (compatible with UNIX 4.3bsd) on some CPUs and TC2000 pSOS+m (a real-time kernel using pSOS+m/88K) on others simultaneously. The system may be dynamically partitioned into clusters of CPUs in order to dedicate system resources to specific functions. nX processes and pSOS tasks on different CPUs in different clusters may communicate using both message-passing and shared-memory models. pSOS tasks may transparently access the nX file system. Persistent, named shared memory objects are supported on a system-wide basis. The user may program using TC2000 parallel FORTRAN, C, and Ada under both nX and pSOS. The TotalView graphical multiprocess/multiprocessor debugger provides a powerful debugging tool for use under nX and pSOS. The TC2000 also supports the X Window System and Sun's NFS. The TC2000 has been generally available for sale since July 1989. If you'd like more information, please send me a message or call us at ACI at (617) 873-6000.
