Prompt Title: Python Datacenter Simulator

Sure, here's an example implementation of a datacenter simulator in Python: ```python from queue import PriorityQueue class Server: def __init__(self, server_id): self.server_id = server_id self.busy_until = 0 def is_busy(self, current_time): return self.busy_until > current_time class Cluster: def __init__(self, num_servers): self.servers = [Server(i) for i in range(num_servers)] self.event_queue = PriorityQueue() self.deferred_queue = PriorityQueue() self.non_deferred_queue = PriorityQueue() def add_event(self, event, time): self.event_queue.put((time, event)) def schedule_deferred_job(self, job, priority, time): self.deferred_queue.put((time, priority, job)) def schedule_non_deferred_job(self, job, priority, time): self.non_deferred_queue.put((priority, time, job)) def run(self, end_time): current_time = 0 while not self.event_queue.empty() and current_time < end_time: time, event = self.event_queue.get() current_time = time if isinstance(event, Job): self.schedule_job(event, time) elif isinstance(event, DeferredJob): self.schedule_deferred_job(event.job, event.priority, time + event.defer_time) elif isinstance(event, NonDeferredJob): self.schedule_non_deferred_job(event.job, event.priority, time) for server in self.servers: server.busy_until = 0 def schedule_job(self, job, time): server = min(self.servers, key=lambda s: s.busy_until) if server.is_busy(time): self.add_event(job, server.busy_until) else: server.busy_until = time + job.duration def print_status(self): for server in self.servers: print(f"Server {server.server_id} is busy until {server.busy_until}") class Job: def __init__(self, duration): self.duration = duration class DeferredJob: def __init__(self, job, priority, defer_time): self.job = job self.priority = priority self.defer_time = defer_time class NonDeferredJob: def __init__(self, job, priority): self.job = job self.priority = priority ``` To use this code, you can create a `Cluster` object with a certain number of servers, add events to its event queue, and then call the `run` method to start the simulation. Here's an example usage: ```python cluster = Cluster(4) # Add some jobs to the event queue for i in range(10): job = Job(duration=5) cluster.add_event(job, time=i) # Schedule a deferred job to run after 20 time units deferred_job = DeferredJob(job=Job(duration=10), priority=1, defer_time=20) cluster.add_event(deferred_job, time=0) # Schedule a non-deferred job with high priority non_deferred_job = NonDeferredJob(job=Job(duration=3), priority=10) cluster.add_event(non_deferred_job, time=5) # Run the simulation for 30 time units cluster.run(end_time=30) # Print the status of the servers cluster.print_status() ``` This is just a basic implementation, and you can modify it according to your specific needs.
