In order to reduce the overhead of barrier synchronization, we have proposed an algorithm which eliminates barrier synchronizations and evaluated its validity experimentally in our previous study. As a result, we have found that the algorithm is more effective to the load-imbalanced program than load-balanced program. However, the degree of the load balance(More)
This paper gives a detailed implementation of a message passing library called MMP. MMP is a user-level l i-brary that has been designed and implemented o n our Maestro PC (Personal Computer) cluster. By accessing a network interface from a user process directly and performing DMA by a dedicated processor on the network interface , MMP can realize a low(More)
