3One program's load sample: GPU share from its node load records, task latencies from its trace, busy time, throughput, its CPU executor's cost.
4
5One slot's load sampler (load.rs Prog).
6
7Each sample (about once a second) reads the program's node load records (NL_*: the GPU share its nodes obtained), node records (busy time, tasks), the trace records written since the last sample (task latencies) and P_DONE, and for a CPU executor (wasm, native) its CPU time and RSS (mesh-cpuuse), and writes the program's PLOAD record: the last second and a window of LOAD_WINDOW samples. Another image in the slot (PT_PTX_HASH, PT_LOADS) starts a fresh baseline.
