What's the Best Type of Interconnection Network for Multiprocessor MIMD Machines? by Simon Loader
With a multiprocessor MIMD machine with several hundred processors it is important that memory access is fast and available. Each of the hundred processors will be accessing different memory location for data and instructions. Any slow access to either will impede upon performance of the machine... Access to memory of any other processors local memory is slow so for fine grained processing which require access to other data and a lot of synchronisation performance is poor. ... Another way to alleviate the problem of fine grained processors on a large MIMD system is to use Cache Coherent...
