Every Kernel Is a Join: Automatic Multi-GPU Parallelism for AI Computations in Einsummable
Zhimin Ding, Chen-Kuan Liao, Chima Adiole +7
Distributing an AI computation across the GPUs of a multi-GPU server is one of the central problems in systems-for-AI. We present Einsummable, a prototype system that accepts a PyT…

Cost-Aware Optimization for Agentic Query Execution
Lunyiu Nie, Yilin Xia, Yiren Liu +2
Classical query optimization searches over algebraically equivalent plans that differ only in cost. This assumption breaks once LLM-backed operators enter the picture: their placem…

Automated Tensor-Relational Decomposition for Large-Scale Sparse Tensor Computation
Yuxin Tang, Zhiyuan Xin, Zhimin Ding +4
A \emph{tensor-relational} computation is a relational computation where individual tuples carry vectors, matrices, or higher-dimensional arrays. An advantage of tensor-relational…
