....are allocated in home statically. Therefore, the migration of data necessitates the support of home migration, which has not been implemented in any previous home based software DSM systems. As a matter of fact, we recently proposed a simple but efficient home migration scheme in the JIAJIA system[4]. With this migration scheme, all the data with single writer characteristic will migrate to the new home automatically, while the ease of locating data is kept. The data migration is implemented by a new function called jia config(HMIG, ON) Here, the first parameter indicates the home migration ....

....in the lock. This protocol maintains coherence through write notices kept on the lock and consequently eliminates the requirement of directory. Some optimization methods of the protocol include single writer detection[3] incarnation number technique[3] write vector technique[5] home migration[4], lazy home page write detection, and SMP optimization. These optimizations can reduce page faults, message amounts, and diffs dramatically and consequently improve performance significantly. 3 The Applications The applications include EM3D from Institute of Electronics, Chinese Academy of ....

....homeless protocols fetch diffs only while the home based protocols fetch the whole page. We have addressed the first problem of home based protocol in another paper and alleviated the impact of the problem through migrating home of pages adaptively according to the application sharing pattern[7]. This paper introduces our efforts to reduce the impact of the second problem in home based software DSMs. The study is done in a homebased software DSM system called JIAJIA[6] Our way of reducing message amount of JIAJIA is to divide each page into blocks and maintain a write vector table for ....

....of a single writer, the data can be migrated close to computation task so that all the future accesses will hit locally. This can be implemented in underlying cache coherence protocol automatically. Therefore, we recently proposed a simple but efficient home migration scheme in the JIAJIA system[2]. With this migration scheme, all the data with single writer characteristic will migrate to the new home automatically. The data migration is implemented by a new function called jia config(HMIG, ON) Here, the first parameter indicates the home migration scheme, and the second parameter controls ....

....of multiple computers are combined to form a larger shared space. In an previous attempt to reduce system overhead, JIAJIA implements a home migration scheme which migrate homes of singly written pages to the single writer processor so that most writes of many applications happen in the home[7]. To further reduce page faults overhead caused by detecting writes to home pages, this paper proposes an adaptive write detection scheme in home based software DSMs. It automatically recognizes single write to a shared page by its home host and assumes the page will continue to be written by the ....

.... 10] and that home based software does not require twin and diff to detect writes to home pages[8] Performance evaluation with SPLASH program suite and NAS Parallel Benchmarks shows that home migration can reduce diffs dramatically in home based software DSMs, hence improve performance[7]. On the other hand, home migration reduces the number of writes to non home pages and increases the number of writes to home pages. Hence emphasizes the importance of reducing home page write detection overheads. 4 Performance Evaluation and Analysis The evaluation is done in the Dawning 1000A ....
