....provide higher performance, and finer grain sharing of the DSM, for example of individual words or cache lines. 3 The Meshix DSM Server SARC s first venture into the area of DSM was to develop an external pager for Meshix; this is currently in use and supports System V Unix style shared memory [5]. The external pager is implemented as a user level server which has the advantage that the server can be changed without having to re compile the kernel. The scheme used places a user level DSM server process on every node. This server handles the DSM requests made by processes on its local node, ....

....upto 256 processors. Each processing node in TOPSY is based on an Motorola 68030 processor and the network is a toroidal circuit switched network with a bandwidth of 12 Mbyte sec channel. A Unix like operating system called Meshix also runs on TOPSY. Recently VSM has been implemented on TOPSY [86] using an external pager approach similar to Mach. This scheme allows distributed Unix processes to share paged virtual memory regions. Coherence is enforced via userlevel server processes and the mechanism is similar to Li s dynamic distributed coherence algorithm. The coherence model is strict ....
