| Abstract | RDMA reduces network latency by eliminating unnecessary copies from network interface card to application buffers, but how to reduce memory registration cost is a challenge. Previous studies use pin-down cache and batched deregistration to address this issue, but only simple LRU is used as a replacement algorithm to manage the cache space. In this paper, we propose an effective cache scheme: Memory Registration Region Cache (MRRC), to minimize the cost of memory registration and deregistration in the critical data path of RDMA operations. MRRC manages memory in terms of memory region, and replaces old memory regions according to both their sizes and recency. We compare the performance of MRRC with traditional RDMA memory registration operations. The results show that MRRC can dramatically reduce the total cost of memory registrations and deregistrations. |
