....Gamma database machine. For a complete description of Gamma see [DEWI86, GERB86] A performance analysis of Gamma can be found in [DEWI88] 2.1. Hardware Configuration Currently 2 , Gamma consists of 17 VAX 11 750 processors, each with two megabytes of memory. An 80 megabit second token ring [PROT85] connects the processors to each other and to another VAX 11 750 running Berkeley UNIX. This processor acts as the host machine for Gamma. 333 megabyte Fujitsu disk drives (8 ) provide database storage at eight of the processors. One diskless processor is reserved for query scheduling and global ....

....need to roll your own hardware. Recently, both Intel and Ncube have added mass storage to their hypercubebased multiprocessor products. 2.2. Gamma Version 1.0 The initial version of Gamma consisted of 17 VAX 11 750 processors, each with two megabytes of memory. An 80 megabit second token ring [PROT85] was used to connect the processors to each other and to another VAX running Unix. This processor acted as the host machine for Gamma. Attached to eight of the processors were 333 megabyte Fujitsu disk drives that were used for storing the database. The diskless processors were used along with the ....

....buffer is assumed. The effective DMA bandwidth at which these buffers can be filled or flushed to the main memory of a processor is assumed to be either 4 Mbits second or 20 Mbits second. The 4 Mbits second number is derived from measurements made on a VAX 11 750 with a Proteon ProNet interface [PROT83] attached to the Unibus. The 20 Mbits second is an estimate of the DMA rate if the device were attached to the internal bus of a VAX 11 750. The token ring is assumed to have a bandwidth of either 10 Mbits second or 80 Mbits second. The 10 Mbits second value is representative of currently ....
....Crystal Multicomputer project was funded as part of the National Science Foundation s Coordinate Experimental Research Program. Crystal is a network of bare VAX 11 750 processors (currently twenty, eventually forty) serving as nodes, connected by a 10 Mbit second token ring from Proteon Associates [PROT83]. This ring is currently being upgraded to an 80 Mbit second ring. Nine node machines have attached disks. File and database services are provided to Crystal users using WiSS. Crystal software provides a simple operating system (NOSE) with multiple, lightweight processes with shared memory and ....
