Dequeue instruction in a system architecture for improved message passing and process synchronizationA system and method for removing a queue entry containing message data from a queue shared by communicating, sequential processes includes dequeue (DEQ) and dequeue or wait (DEQW) instructions. The ...
MPI can also be addressed whenever process synchronization is discussed, with the networking delay being accounted for, and the ramifications that this has on the performance of synchronization operations. Finally, a very appropriate time to discuss MPI is in a course of data structures and ...
This improvement allows us to remove statically a significant number of infeasible synchronization edges that would otherwise have to be analyzed later by the tester. In this paper, the test model is presented using the Message-Passing Interface standard; however, our new model has been designed ...
Two inter-process communication models, shared-variable and message-passing are, used on both the shared- and the distributed-memory architectures. We consider the process waiting mode the main distinction between the two IPC models. If a process waits for one event, it works in the non-selecti...
A wait-free protocol for message passing on non-coherent buffers was introduced with the RCKMPI library, in order to support MPI on the SCC. In this work, the message passing performance of the protocol is modeled. Additionally, a port for symmetric multi-processors is introduced and used ...

我们分析了trace数据,并且识别出MPI进程间的idle出阿波。我们发现两个系统self-synchronization的证据。 4.1 idle period的传播 我们研究了在256个进程上100次计算循环的短期执行过程,idle period少,很哪可视化。 idle trace揭示了初始阶段硬件拓扑依赖关系,我们可以从图中清晰看出每个process的硬件关系,我们用线区分不同...
Even with the use of Compare and swap based algorithms that doesn't require synchronization, it is possible that a lot of processor cycles will be spent sending cache coherence messages to each of the processors. A system built of Message passing semantics is inherently more scalable. Since ...

then when it does get around to receiving S2’s and S3’s replies, it could end up with two separate threads processing those replies. To relieve the application developer from the synchronization that would be required between these two threads, Service Broker has a built-in locking protocol....
