ClusterOps

ClusterOps is an enterprise-grade Python library developed and maintained by the Swarms Team to help you manage and execute agents on specific CPUs and GPUs across clusters. This tool enables advanced CPU and GPU selection, dynamic task allocation, and resource monitoring, making it ideal for high-performance distributed computing environments.

---

Features

• CPU Execution: Dynamically assign tasks to specific CPU cores.
• GPU Execution: Execute tasks on specific GPUs or dynamically select the best available GPU based on memory usage.
• Fault Tolerance: Built-in retry logic with exponential backoff for handling transient errors.
• Resource Monitoring: Real-time CPU and GPU resource monitoring (e.g., free memory on GPUs).
• Logging: Advanced logging configuration with customizable log levels (DEBUG, INFO, ERROR).
• Scalability: Supports multi-GPU task execution with Ray for distributed computation.

---

Installation

pip3 install -U clusterops

---

Quick Start

The following example demonstrates how to use ClusterOps to run tasks on specific CPUs and GPUs.

from clusterops import (
   list_available_cpus,
   execute_with_cpu_cores,
   list_available_gpus,
   execute_on_gpu,
   execute_on_multiple_gpus,
)

# Example function to run
def sample_task(n: int) -> int:
    return n * n


# List CPUs and execute on CPU 0
cpus = list_available_cpus()
execute_on_cpu(0, sample_task, 10)

# List CPUs and execute using 4 CPU cores
execute_with_cpu_cores(4, sample_task, 10)

# List GPUs and execute on GPU 0
gpus = list_available_gpus()
execute_on_gpu(0, sample_task, 10)

# Execute across multiple GPUs
execute_on_multiple_gpus([0, 1], sample_task, 10)

GPU Scheduler

The GPU Scheduler is a Ray Serve deployment that manages job execution with fault tolerance, job retries, and scaling. It uses the GPUJobExecutor to execute tasks on available GPUs.

See the GPU Scheduler for more details.

from clusterops import gpu_scheduler


async def sample_task(n: int) -> int:
    return n * n


print(gpu_scheduler(sample_task, priority=1, n=10))

Configuration

ClusterOps provides configuration through environment variables, making it adaptable for different environments (development, staging, production).

Environment Variables

• LOG_LEVEL: Configures logging verbosity. Options: DEBUG, INFO, ERROR. Default is INFO.
• RETRY_COUNT: Number of times to retry a task in case of failure. Default is 3.
• RETRY_DELAY: Initial delay in seconds before retrying. Default is 1 second.

Set these variables in your environment:

export LOG_LEVEL=DEBUG
export RETRY_COUNT=5
export RETRY_DELAY=2.0

print(f"Available CPUs: {cpus}")

---

select_best_gpu() -> Optional[int]

Description:
Selects the GPU with the most free memory.

Returns:

• Optional[int]: The GPU ID of the best available GPU, or None if no GPUs are available.

Example Usage:

best_gpu = select_best_gpu()
print(f"Best GPU ID: {best_gpu}")

---
