GPU-accelerated analytical query processing is often limited by both GPU device memory capacity and host-to-device data transfer time. Modern data compression techniques, such as cascaded lightweight compression, can mitigate these issues. However, existing designs all exhibit critical tradeoffs on compression ratios,...

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.

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...
