The computational resources deployed by the MoST team

The Turbulence Modeling and Simulation team deploys a number of computational resources specific to its activities in addition to those available at LEGI.

  • The high availability virtualization cluster
    Based on 3 DELL R530 (quorum), this high-availability virtualization cluster is running Proxmox-VE and provides all the critical services to support (nearly) H24, 7D/7 availability. This concerns the name resolution, authentication, cluster management ... but also the critical data storage which is distributed and replicated among the nodes (CEPH). It allows hot migrations of virtual machines (without service disruption) and provides resilience, without human intervention, to most technical failures.
  • The cluster for distributed parallel computing
    This 400 cores cluster is running the Rocks Cluster distribution and is build around a fast (40Gbits / s) and low latency infiniband QDR network to specifically meet the needs of distributed highly parallel simulations run by the team. It allows MoST to develop the simulation codes and to carry out part of the meso-resolution calculations, upstream of the large supercomputers of the national centers.
  • The nodes dedicated to 3D vizualization and large data processing
    • A graphic workstation (HP Z800), with two Nvidia Quadro FX 4800 GPUs, 2 xéons (X5660) and 24GB of RAM dedicated to 3D data visualization.
    • A DELL R730 server for intensive 3D visualizations, configured with two 10-core Haswell-EP Xéons (E5-2660 v3), 512GB of RAM, and an AMD Firepro W7000 GPU. It enables large data volumes to be viewed using remote session solutions.
    • A pre and post-processing server, with 4 Xéons gold 6148 (80 cores in total) and 1.5TB of RAM allows to process very large data resulting from simulations at very high resolutions on the GENCI supercomputers.
