Benefits of running on ICHEC • Scale up on tightly coupled infrastructure – RDMA – High Bandwidth Parallel filesystem

• Ansys Fluent 15.0 introduced GPGPU support – New Algebraic Multigrid (AMG) linear system solver optimised for GPGPU – speed ups in Fluent depend on the portion of the time spent in the linear solver – 1 GPU socket licensed as 1 CPU core

Evolution of Cloud Solutions • License management – More flexible licensing badly needed • Assumption of local network no longer reality • Dynamic token/feature requirements

• Portability – Require ability to create similar software environment on arbitrary hardware resources on demand – Orchestration tools to create virtual private clusters – Application Containers (Docker, etc) – Persistent storage – Remote visualization

• Next gen of ICHEC HPC systems will seek to address these issues
