Cluster computers have become the vehicle of choice to build high performance computing environments. To fully exploit the computing power of these environments , one must utilize high performance network and protocol technologies, since the communication patterns of parallel applications running on clusters require low latency and high throughput, not(More)
— Cluster computers have become the de facto mechanism to build high performance computing environments. To fully exploit the computing power of these environments, one must utilize high performance network and protocol technologies, since the communication patterns of parallel applications running on clusters require low latency and high throughput, not(More)
Zero-copy communication exchanges the messages among the buffers that are allocated and locked before the communication itself. This communication style fits into applications that the communication timings and the message sizes are known in its initialization phase. However, another application with non-deterministic messaging such as web or parallel(More)
The communication performance is an important factor of the performance in cluster computer, which must be considered for the challenge that tries to improve its overall performance to accomplish the desired one. This paper focuses on the communication method for reducing the communication data in cluster computer using a data compression mechanism based on(More)
A cluster has become a popular platform for high performance computing. Currently, many PC clusters are organized with cost-effective conventional wide-area network technologies to connect each processing elements. Here, it is difficult to extract potential performance of the cluster, since there is the disparity between the wide-area network technologies(More)
