# Capture one DynamoRIO trace per selected SimPoint, then raw2trace + minimize.
#
# Mirrors scarab-infra's cluster_then_trace flow (common/scripts/
# run_simpoint_trace.py) with SEG_SIZE as both the fingerprint segment size and
# the drraw2trace chunk size, and one warmup chunk. Each released archive keeps
# chunk.0000 (warmup) + chunk.0001 (the SimPoint region) == 2 * SEG_SIZE
# instructions.
