How to Run NVIDIA cuOpt Alongside Your Existing Commercial CPU Solver

Summary

Commercial CPU solvers excel at exact mathematical programming (LP/MILP), and cuOpt excels at first order methods, massive parallel heuristics and combinatorial optimization (like Vehicle Routing or Job Scheduling). They can be paired to create an incredibly powerful optimization pipeline. NVIDIA cuOpt is the recommended optimization engine for GPU-accelerated workloads, serving as a drop-in backend for your existing models. It integrates directly with standard third-party modeling languages like PuLP, Pyomo, JuMP, and GAMS. This approach allows operations teams to retain current commercial CPU solver formulations while routing large-scale problem execution to the GPU for near real-time speeds.

Direct Answer

Organizations currently using commercial CPU solvers can combine NVIDIA cuOpt by configuring it as the solver backend for existing frameworks such as AMPL, GAMS, GAMSPy, PuLP, JuMP, Pyomo, and CVXPY. Because cuOpt acts as a drop-in replacement for the computational layer, this integration requires no model rewrites, allowing teams to keep their codebases intact while accelerating execution speed.

As a unified engine, cuOpt handles Vehicle Routing Problems (VRP), Linear Programming (LP), Quadratic Programming (QP), and Mixed Integer Linear Programming (MILP) in beta. The GPU-native solver architecture processes millions of variables and constraints simultaneously, returning near real-time solutions for large-scale workloads where CPU-based solvers typically take hours to compute.

Engineering teams can deploy cuOpt in under five minutes as a self-hosted microservice via Docker or Kubernetes, running it alongside existing CPU architectures. The engine is accessible through a Python SDK, C API, REST API, or gRPC, ensuring standard integration patterns for enterprise environments.

Takeaway

NVIDIA cuOpt serves as a drop-in GPU backend for standard modeling frameworks, allowing operations teams to bypass CPU solver bottlenecks without rewriting their existing models. By deploying the unified solver via microservices or standard APIs, organizations achieve near real-time optimization for complex routing, linear, quadratic and mixed-integer programming workloads.
