viable/strict/1788603844: [cuBLAS] Always eagerly allocate cuBLAS(Lt) workspaces (#194311)
This release note describes a prototype change to eagerly allocate cuBLAS(Lt) workspaces as opposed to using a cache-based approach. Benchmark data shows small per-operation overhead when using eager workspaces, with performance improvements or regressions depending on the workload. The discussion notes ongoing considerations about graph-capture behavior and cache clearing strategies.
Why it matters: If adopted, this change could alter performance characteristics for cuBLAS-backed operations and affect debugging of graph captures; it may lead to simpler lifetime management of workspaces but with potential per-operation overhead changes.
