cf. Makefile for the code
make clone to download the workspace
make sequential to run workflow in sequence
make start-server & to start the METS server (in the background)
make parallel to run workflow in parallel page-wise (with timeouts and error fallback)
make parallel-chunks to run workflow in parallel job-wise (without error handling)
ocrd workspace list-page --help for the partitioning/chunking options
make rm-sequential and make rm-parallel to remove the workspaces
Variables:
PROCESSOR - which processor to run. Defaults to ocrd-vandalizeNUMBER_OF_THREADS - how many jobs to run in parallelECHO - set to echo to dry-runOn a machine w/ 8 cores.
