Work Dictionary

The work dictionary contains metadata that is used by the manager to send a packet of work to a worker. The dictionary uses integer keys i and values that determine the data given to worker i. Populated in the allocation function. Work[i] has the following form:

Work[i]: [dict]:

    Required keys:
    "H_fields" [list]: The field names of the history H to be sent to worker i
    "persis_info" [dict]: Any persistent info to be sent to worker i
    "tag" [int]: "EVAL_SIM_TAG"/"EVAL_GEN_TAG" if worker i is to call sim/gen_func
    "libE_info" [dict]: Info sent to/from worker to help manager update the H array

    libE_info contains the following:
    "H_rows" [list of ints]: History rows to send to worker i
    "rset_team" [list of ints]: The resource sets to be assigned (if dynamic scheduling is used)
    "persistent" [bool]: True if worker i will enter persistent mode (Default: False)

The work dictionary is typically set using the gen_work or sim_work helper functions in the allocation function. H_fields, for example, is usually packed from either sim_specs["in"], gen_specs["in"] or the equivalent “persis_in” variants.
