Graph split event tracker #159795

haowu14 · 2025-08-04T20:52:17Z

Summary:
A tool to track events in graph split, specifically on how nodes being end up in acc or cpu subgraphs.

Usage: use env var to specify a mode and necessary arguments.

FX_NET_ACC_SPLITTER_TRACKER_MODE: Tracker mode.

Different modes of the event tracker:
"0": Tracker not enabled (by default)
"1": Tracker enabled but no dumps. Information available by setting breakpoints and visually inspect in pdb.
"2": Tracker enabled and dumps all events to DUMP_PREFIX_all.txt
"3": In addition to events dump, track nodes specified by ENV_FX_NET_ACC_SPLITTER_TRACKER_TRACKED_NODES recusrively and dump to DUMP_PREFIX_nodex.txt
"4:: In addition to events dump, track all nodes with more than 1 event recusrively and dump to DUMP_PREFIX_nodex.txt

FX_NET_ACC_SPLITTER_TRACKER_DUMP_PATH: overriding dump path. Leave empty for ~.
FX_NET_ACC_SPLITTER_TRACKER_TRACKED_NODES: Nodes to track for mode "3".

Test Plan: New unit test

Instead of doing it by an envvar, can we just dump it by default to tlparse using trace_structured?

I think I can make a default dump of all events flat via trace_structured, while preserving the local dump for a quick debug process.
Later we can followup to visualize in fancier ways via tlparse.

Even when you have a wordy debug mode it can be helpful to use dtrace to put it in a structured log as you can conveniently get the logs out of a MAST job in that case
