....the programmer and provide a programming model based on shared data rather than message passing. Li laid the foundation for this work by building a system that simulates physical shared memory on top of distributed memory hardware [30] Many other, more advanced DSMs have subsequently been built [6, 7, 11, 14,17, 23,26, 28, 36,37, 40,43, 44, 45]. The DSM system studied in this paper is Orca. Orca s programming model was designed and implemented prior to most other DSM systems [5] and differs from other DSM models by being object based and language based. Orca encapsulates shared data in objects, and allows the programmer to define ....

....than TreadMarks for Barnes Hut and TSP and the same performance for Water. 29 5. RELATED WORK We discuss three areas of related work: distributed shared memory, parallel languages, and sharing patterns. Distributed Shared Memory Many other distributed shared memory systems have been built [6, 7, 11,17, 26,28, 36, 37,40, 43,44, 45]. In the paper, we mainly discussed page based (e.g. TreadMarks) and object based (e.g. CRL) DSM. Another interesting class of DSM systems is fine grained DSM, which tries to reduce false sharing by using a unit of sharing that is smaller than a physical page. Examples are Blizzard S [45] and ....

....[35] supports automatic update release consistency [22] which is a hardware assist to shared memory that automatically flushes writes to a home process. Remote processes then retrieve an entire pages of valid data from the home process on an access violation, as is done in Munin. The CASHMERe [36] prototype consists of 32 processors constructed from eight 4 processor DEC 2100 4 233 multiprocessors interconnected through a Memory Channel network. The Memory Channel provides a mechanism for implementing fine grained sharing in the CASHMERe architecture. SoftFLASH [37] provides an aggressive ....

....(cache line) Along the other dimension, Beehive provides a set of explicit communication mechanisms that allow the producer of data to push it to prospective consumers thus avoiding the read stall overhead at the receiving end. While there have been several other efforts in building DSM systems [3, 11, 12, 16, 21], to the best of our knowledge, all such efforts support the standard spatial notions of synchronization and consistency. The primary contributions of this paper are: ffl temporal mechanisms for consistency and synchronization to enhance the shared memory programming paradigm for time based ....

....algorithm based on reachability analysis is run less frequently to garbage collect items with unknown reference counts. 7 Related Work The STM abstraction may be viewed as a form of structured shared memory. In this sense it is related to recent distributed shared memory systems (such as Cashmere [13], Shasta [19] and Treadmarks [11] DSM systems typically offer the same API as any hardware SMP system and therefore are too low level to simplify programming of the complex synchronization and communication requirements found in interactive multimedia applications (as mentioned earlier, STM is ....
