Scaling Up Memory Disaggregated Applications with SMART

Abstract

Recent developments in RDMA networks are leading to the trend of memory disaggregation. However, the performance of each compute node is still limited by the network, especially when it needs to perform a large number of concurrent fine-grained remote accesses. According to our evaluations, existing IOPS-bound disaggregated applications do not scale well beyond 32 cores, and therefore do not take full advantage of today's many-core machines.
