Chunk 7.1

In this chunk, the assistant completed the targeted redeployment on hosts 93197 and 88910 by destroying the remaining old manual instance (32705217) and cleaning stale database entries. Two new instances were created using the fixed Docker image and the `--onstart-cmd` workaround: instance 32711932 (2x RTX 3090, BC Canada, 125GB RAM) and instance 32711934 (1x RTX 4090, Norway, 500GB RAM). Both started successfully, registered with the vast-manager, and began downloading Filecoin proof parameters. While the Norway instance progressed smoothly and successfully completed its warmup proof—validating the entire pipeline—the BC Canada instance was killed by the OOM killer during its first benchmark run. Investigation revealed that the 125GB RAM on the BC host was insufficient for the initial proof synthesis when using the default 10 partition workers, as the uncached PCE caused organic memory allocation to exceed available resources. In contrast, the Norway instance's 500GB RAM handled the load without issue. This failure shifted the focus from deployment logistics to hardware-aware pipeline configuration. The successful completion on the high-memory instance proved the core software stack was sound, but the BC OOM highlighted a critical scalability constraint. The proposed fix—reducing the number of partition workers specifically for the warmup proof (so the uncached synthesis doesn't exhaust memory) before scaling up for subsequent cached proofs—aims to adapt the benchmark to limited memory environments. The themes of this chunk center on the transition from platform-specific debugging to workload-specific resource tuning, hardening the system against the diverse hardware constraints encountered in the Vast marketplace.
