Operational deployment ties an Elastic Stack + Splunk pipeline to a DGX-1 multi‑GPU box and targets PaloAlto‑7080 session logs; processing a 729 GB test dump initially takes ~910–1600 minutes but is reduced overall about 10×. Key techniques: multi‑process invocation of Elasticsearch scroll API with 128 chunks, CUDA Thrust bitwise transform for direction discrimination replacing slow CPU bitmask loops, and pairwise MapReduce-style reduction on GPUs for histograms, shrinking histogram time from ~476 minutes to ~12 minutes and discrimination from ~704 to ~174.
