WebJun 18, 2024 · Existing work addresses this redundancy with coarse-grained lineage tracing and reuse for ML pipelines, composed of high-level primitives. This approach allows reusing existing ML systems, but views entire algorithms as black boxes, and thus, fails to eliminate fine-grained redundancy and handle internal non-determinism. WebWe have two paradigms for parallel programming. Coarse grained (grid, cluster) model and Fine grained model (multi core processors like GPU, CELL/BE etc). While Java has a proven track for grid computing model, I find its performance to be unsatisfactory in multicore programming (like JCUDA for GPGPU). And there are very few and
