Abstract
In recent years, parallel computing is one of the main ways to increase computer performance. High performance parallel computers apply to the fields of commerce, defense, and science, where high performance computing benefits numerical simulations, a major way to accelerate improvement of the current science.
Many people begin to research and develop distributed systems which perform parallel computing. To design a distributed system is complicated and difficult. Fault tolerance is an important indicator in many characteristics worthy to be particularly designed. Although every computer in a distributed system may fail, fault tolerance has the capability to deal with the failures in the system. Thus, how to make a system free from failures when in executing is an important study in fault tolerance.
The methods of rollback recovery are divided into checkpoint and message log. These two methods have different algorithms. Until now, no algorithm is admittedly the most efficient. Thus, we have to choose a different algorithm in different environments or circumstances to get the best efficiency.
This goal of this paper is to discuss the differences in fault tolerance methods in MPI-based distributed system. We implement a MPI-based fault tolerant middleware with non-blocking message logging protocol, measure its performances, and share practical experience with others.
