ABSTRACT:
An embodiment of the invention provides an apparatus and method for performing RDMA (Remote Direct Memory Access) network configuration. The apparatus and method measure a performance of each RDMA operation for different data message sizes and determine an RDMA operation to be applied for a particular packet size sent by an application, based on the measured performance. As an example, the RDMA operations are, e.g., RDMA send/receive, RDMA write, RDMA read, memory registration and memory un-registration, or memory bind and memory unbind. The measured performance can be, for example, the total time to perform an RDMA operation for different packet sizes.
