A Case Against CXL Memory Pooling
Philip Levis, Kun Lin, A.T. Tai
Abstract
Compute Express Link (CXL) is a replacement for PCIe. With much lower latency than PCIe and hardware support for cache coherence, programs can efficiently access remote memory over CXL. These capabilities have opened the possibility of CXL memory pools in datacenter and cloud networks, consisting of a large pool of memory that multiple machines share. Recent work argues memory pools could reduce memory needs and datacenter costs.
