The lapis library provides a framework and runtime for simulating the scheduling and usage of opportunistic and static resources.

Currently the library provides a simple command line interface that allows three modes of operation:

• static provisioning of resources,
• dynamic provisioning of resources, and
• hybrid provisioning of resources.

In the most simple case you can apply a given workload, e.g. downloaded from the parallel workload archive to a static resource configuration:

python3 simulate.py --log-file - static --job-file <path-to-workload> swf --pool-file <path-to-pool-definition> htcondor

The output of simulation is given to stdout. You have further options you can explore via

python3 simulate.py --help

and more specifically for the different operation modes with

python3 simulate.py static --help
