#ifndef _SCHEDULER_OP_
#define _SCHEDULER_OP_
// SCHEDULER_OP encapsulates the policy and mechanism
// for communicating with scheduling servers.
// It is implemented as a finite-state machine.
// It is active in one of two modes:
// get_work: the client wants to get work, and possibly to
// return results as a side-effect
// return_results: the client wants to return results, and possibly
// to get work as a side-effect
//

// fetch and parse master URL if nrpc_failures is a multiple of this
