    Nowadays, multi-core chips are becoming the norm for the computer market. When one considers MPI collective communications with several processor cores on a node, one also has to consider the impact of such new architecture on widely used MPI implementations, in order to realize the communication efficiently and achieve high performance computing. This paper provides a succinct comparative analysis between dynamic and static MPI implementations on multi-core computers. MPI Alltoall collective operation is used as an example to handle the communication process involved in a load unbalanced case, and then among different communicators. The experiments performed on clusters equipped with high performance interconnects, such as Infiniband and Gigabit Ethernet, revealed that the dynamic version is more likely to be adapted with the general and random behaviors of the system for this new trend of computer architectures.
