LAM: Efficient Lossy Agent Memory Framework With A Retrieval-Score Error Bound

Agent memory grows as agents read inputs, reason, and call tools. Longer histories increase inference cost and eventually exceed the context window. LLM-based summarization reduces this history but adds latency and provides no explicit bound on information loss. We propose LAM, a Lossy Agent Memory system with three co...

ECAS: An Edge-Controlled Agentic System for Validation-Gated Scientific Application Execution

Scientific applications increasingly rely on high-performance computing (HPC), yet translating a scientist's high-level goal into a correct target-scale execution remains brittle and labor-intensive. Large language model (LLM) agents promise to automate this, but two obstacles remain: granting a cloud-hosted model dire...

FaCTz: Fast Critical-Point and Topology-Aware GPU Compression for Scientific Vector Fields

Error-bounded lossy compression is essential for storing and transferring the vector-field data produced by large-scale scientific simulations. Although it enforces a user-specified error bound to limit numerical distortion, it does not preserve the field's topology: small admissible perturbations can create or elimina...
