Open Standards Open standards for instruction sets, software systems and interconnects make it possible to obtain easily and inexpensively the key components making up a multiprocessor system. The chip set from Newbridge implements the Futurebus standard for the interconnection and relieves us from developing our own bus. This workstation serves as the console for the testbed and, additionally, executes its I O requests. I O bandwidth is 1.25 Mbytes per second, which is more than suf 9 ficient for a 10 MIPS machine.

Strong order is still a requirement of many commercial systems.
Besides the presence bits and the modify bit per block, we have added some transient state bits to support concurrent transactions on different directory entries. Catanzaro, B., Multiprocessor System Architectures . No context found. Multiprocessor System Architectures . Sun Microsystems, 1994.
