Today’s distributed data processing frameworks (DDFs) have large memory and network transfer overheads because these frameworks require that each node (server or VM) copy objects into local memory before processing. Emerging shared disaggregated memory (SDM) clusters enable an alternate approach...

CXL allows multiple hosts to share memory. However, the hardware is expected to provide cache coherence only for a small region of CXL memory and it is difficult for hosts to share data in the non-coherent region. Recent work proposes using the small coherent region (SCR) to track coherence metad...
