Chunk 24.1

This chunk executed the systematic `partition_workers` sweep requested by the user to find the optimal setting for the Phase 8 dual-worker GPU interlock. The assistant methodically benchmarked pw values of 10, 12, 15, 18, and 20 by restarting the daemon for each configuration, waiting for SRS preload, and running the standard 5-proof batch benchmark with `c=5 j=3`. The results revealed a narrow performance band: pw=10 and pw=12 tied for the best throughput at **43.5s/proof**, pw=18 followed closely at **43.8s/proof**, while pw=15 (**44.8s/proof**) and pw=20 (**44.9s/proof**) showed slight regressions. This data confirms that pw=10–12 is the optimal range for this 96-core machine, with higher partition counts risking CPU contention that starves GPU preprocessing threads. The execution encountered several operational hiccups—command timeouts and a `sed` substitution that failed to persist—requiring the assistant to debug and recover by manually rewriting the config file and restarting the daemon in separate, robust steps. Despite these issues, all five sweep points were successfully completed and recorded, fulfilling the user's request and providing a clear empirical basis for the production `partition_workers` setting. The todo list was fully marked complete, and the daemon was shut down at the end of the sweep.
