Collective communications compose a significant portion of the communications in many high performance applications. The multi-destination message passing mechanism has been proposed recently for efficient implementation ofcollectiv e operations by using a fewer number of communication phases. However, this mechanism has been only employed for improving the performance of non-personalized collective operations such as multicast. In this paper, we investigate whether multi- destination message passing can also help personalized communications such as one-to-all scatter. We propose a new scheme, called Sequential Multidestination Tree-based (SMT) scheme, which takes advantage ofthe multidestination message passing mechanism and provide a better per- formance. For a range of system sizes and parameters, it is shown that the SMT scheme outperforms other known schemes for a wide range of message lengths.
