Code Migration

Seamlessly port and refactor HPC codes across diverse hardware platforms.

CODE TRANSFORMATION

PLATFORM MIGRATION

IT Services Portfolio

Architecture-agnostic code transformation

Complete refactoring and modernization of legacy HPC codes (Fortran 77/90, C/C++, MPI/OpenMP) to modern, maintainable, and performance-portable standards (Fortran 2008/2018, C++17/20, SYCL/oneAPI, Kokkos, RAJA) without loss of scientific fidelity

CPU → GPU / accelerator migration

Full porting and optimization from CPU-only codebases to GPU (CUDA → HIP → SYCL), multi-GPU, and heterogeneous architectures, including kernel extraction, data layout redesign, memory hierarchy tuning, and asynchronous execution strategies

Vendor lock-in elimination & back-end portability

Migration to performance-portable programming models (SYCL, OpenMP target offload, Kokkos, Raja, stdpar) to achieve seamless runnability and comparable performance across NVIDIA, AMD, Intel, ARM, and emerging accelerators

MPI + threading hybrid modernization

Transformation of pure MPI codes into efficient hybrid MPI + OpenMP/OpenMP target / MPI + SYCL models, with topology-aware process/thread binding, overlap of communication & computation, and reduction of MPI overhead

Legacy-to-cloud / exascale readiness

Step-by-step migration from on-premise clusters to cloud HPC (AWS ParallelCluster, Azure CycleCloud, Google Cloud HPC Toolkit) or exascale-class systems, including containerization (Singularity/Apptainer/Podman), batch scheduler integration (Slurm, PBS), and cost-aware scaling strategies

End-to-end migration with performance assurance

Full lifecycle support: baseline profiling → transformation → validation on target platform → regression testing → performance benchmarking → handover with training & documentation, guaranteeing ≥90–95 % of original performance or better on the new platform
