چکیده
The Compute Express Link (CXL), a trademark of the CXL Consortium, protocol enables creating pools memory and accelerators, allowing disaggregation, composable virtual machines that make more efficient use memory. New software will even useful.

Efficient Memory Disaggregation with Infiniswap
Memory-intensive applications suffer large performance loss when their working sets do not fully fit in memory. Yet, they cannot leverage otherwise unused remote memory when paging out to disks even in the presence of large imbalance in memory utilizations across a cluster. Existing proposals for memory disaggregation call for new architectures, new hardware designs, and/or new programming mode...
متن کاملTaming Weak Memory Models
Speculative techniques in microarchitectures relax various dependencies in programs, which contributes to the complexity of (weak) memory models. We show using WMM, a new weak memory model, that the model becomes simpler if it includes load-value speculation and thus, does not enforce any dependency! However, in the absence of good value-prediction techniques, a programmer may end up paying a p...
متن کاملDecentralized Memory Disaggregation Over Low-Latency Networks
Mosharaf Chowdhury is an Assistant Professor in the EECS Department at the University of Michigan. His research ranges from resource disaggregation in low-latency RDMA networks to geo-distributed analytics over the WAN, with a common theme of enabling applicationinfrastructure symbiosis across different layers of corresponding software and hardware stacks. [email protected] Memory disaggregati...
متن کاملTowards Resource Disaggregation - Memory Scavenging for Scientific Workloads
Compute clusters, consisting of many, uniformly built nodes, are used to run a large spectrum of different workloads, like tightly coupled (MPI) jobs, MapReduce, or graph-processing data-analytics applications, each of which with their own resource requirements. Many studies consistently highlight two types of under-utilized cluster resources: memory (up to 50%) and network. In this work, we ta...
متن کاملDisaggregation of Long Memory Processes on C∞ Class
We prove that a large set of long memory (LM) processes (including classical LM processes and all processes whose spectral densities have a countable number of singularities controlled by exponential functions) are obtained by an aggregation procedure involving short memory (SM) processes whose spectral densities are infinitely differentiable (C∞). We show that the C∞ class of spectral densitie...
