Core Capabilities
MARUT is designed from the ground up for modern GPU architectures, delivering significant performance gains over traditional CPU-based solvers. Its optimized parallel computing framework enables rapid turnaround times for large-scale, high-resolution simulations, making it well-suited for both research and industrial applications.
Multi-GPU MPI-Based Scaling: Building on its GPU-accelerated foundation, MARUT employs an MPI-based parallel framework to scale efficiently across multiple GPUs and compute nodes. This enables seamless workload distribution and high parallel efficiency, allowing the solver to tackle extremely large and complex simulations while maintaining strong scaling performance.
High-Order Discontinuous Galerkin Methods: At its core, MARUT employs high-order spectral Discontinuous Galerkin (DG) methods for spatial discretization. This approach provides: Superior accuracy for resolving complex flow structures, Reduced numerical dissipation, Efficient handling of wave propagation and discontinuities
