GUMPIM: Unitary and Malleable Memory for Processing-in-Memory with Guaranteed PIM Pages

GUMPIM is proposed, a PIM system that allows interleaved CPU pages and non-interleaved PIM pages to coexist in a Unitary and Malleable memory space with Guaranteed PIM page allocation and enables zero-copy during PIM task offloading and maintains CPU memory bandwidth while ensuring low PIM offloading overhead.

CELLServe: An SLO-Aware and Cost Efficient LLMs Serving System for Serverless Computing Environments

CELLServe formalizes SLO-constrained joint resource provisioning as an optimization problem with a dedicated algorithm, and introduces an opportunistic instance merging strategy for decode phase functions to reclaim fragmented resources.

GUMPIM: Unitary and Malleable Memory for Processing-in-Memory with Guaranteed PIM Pages

DRAM-based Processing-in-Memory (PIM) addresses the “memory wall” by executing computations directly inside main memory. However, memory interleaving and virtual memory limit contiguous data size visible to PIM units, constraining PIM task granularity. Fine-grained PIM tasks incur significant offloading overhead that n...

gPooling: An Elastic GPU Resource Management Framework for On-Demand Virtualization in Shared Accelerator Clusters

With the rapid growth of artificial intelligence (AI) and high-performance computing (HPC), GPUs and other accelerators have become a shared computing substrate for a wide range of workloads. However, many shared accelerator clusters still rely on coarse device-level allocation, which often leads to low effective utili...
