Parameters
----------
wd : str, optional
Working directory where QCG-PilotJob manager should be started, by default it is
a current directory
resources : str, optional
The resources to use. If specified forces usage of Local mode of QCG-PilotJob Manager.
The format is compliant with the NODES format of QCG-PilotJob, i.e.:
[node_name:]cores_on_node[,node_name2:cores_on_node][,...].
Eg. to define 4 cores on an unnamed node use `resources="4"`,
to define 2 nodes: node_1 with 2 cores and node_2 with 3 cores, use `resources="node_1:2,node_2:3"`
reserve_core : bool, optional
If True reserves a core for QCG-PilotJob Manager instance,
by default QCG-PilotJob Manager shares a core with computing tasks
Parameters.
enable_rt_stats : bool, optional
If True, QCG-PilotJob Manager will collect its runtime statistics
wrapper_rt_stats : str, optional
The path to the QCG-PilotJob Manager tasks wrapper program used for collection of statistics
log_level : str, optional
