A new partitioning algorithm that provably load-balances arbitrary sparse tensor algebra expressions by generalizing parallel merging to multi-operand, multi-dimensional hierarchical structures, implemented in a compiler framework.
Proposes AROM to shift LtRAM management to the OS by making pages read-only to applications, using CoW faults for writes to simplify DIMM hardware.
CXL-ClusterSim is a full-system simulation framework combining gem5 and SST to model CXL disaggregated memory for pooling and sharing.
Proxics introduces lightweight virtual processors and low-latency communication channels as portable OS abstractions for programming near-data processing accelerators, demonstrated on real hardware for memory-intensive workloads.
Mambalaya delivers 4.9x prefill and 1.9x generation speedups on Mamba layers over prior accelerators by systematically fusing inter-Einsum operations.
CCCL delivers 1.34-1.94x faster cross-node GPU collectives via CXL memory pooling than 200 Gbps InfiniBand RDMA, with 1.11x LLM training speedup and 2.75x hardware cost reduction.
Equilibria delivers per-container fairness controls and observability for CXL memory tiering, improving production workload performance by up to 52% over Linux TPP while suppressing noisy-neighbor interference.
PRISM introduces a probabilistic performance modeling framework that quantifies guarantees on training time for large-scale distributed systems under runtime variability.
