BLCR (Utility)

Introduction

BLCR is an application for checkpointing and restarting jobs. No instrumentation or modification of user source code or recompiling is required to use blcr on sharcnet. BLCR is particularly useful for jobs killed unexpectedly due to power outages or exceeding the 7day run limit. BLCR is installed on orca for use with serial or threaded jobs originating from dynamically linked binaries (statically built binaries are NOT supported).
