    • HPC  Cloud   Clouds  on  Supercomputers  for  HPC Informa(on  Technology  Research  Ins(tute,     Na(onal  Ins(tute  of  Advanced  Industrial  Science  and  Technology  (AIST),  Japan SC2013@Denver  AIST  Booth  #3309
    • HPC  Cloud:  a  promising  pla7orm  for  HPC High Performance Usability HPC Cloud Energy Efficiency Scalability 2
    • High Performance Impact  of  VMM-­‐bypass  I/O •  Performance  evalua@on  of  HPC  cloud   Execution time [seconds] –  (Para-­‐)virtualized  I/O  incurs  a  large  overhead.   –  PCI  passthrough  significantly  mi@gate  the  overhead.   KVM (IB) 300 BMM (IB) 250 BMM (10GbE) VM1 KVM (virtio) VM1 Guest OS 150 100 Guest OS Physical driver 200 Guest driver VMM 50 VMM Physical driver 0 BT CG EP FT LU The  overhead  of  I/O  virtualiza@on  on  the  NAS  Parallel   Benchmarks  3.3.1  class  C,  64  processes.

    • High Performance HPC  Cloud  OS Energy Efficiency •  Bare  metal-­‐comparable  I/O  performance   –  Integra@on  of  VMM-­‐bypass  I/O  into  the  Apache  CloudStack Provide a compute offering with a PCI passthrough device Admin UI API End User UI Host Cloud agent management server Resource allocator Cloud agent VM virtio_net NIC VM VMs for web servers PCI passthrough VM IB HCA Live migration Cloud VM agent Deploy a VM VMs for HPC IB HCA 4

    • HPC  Cloud  federaGon Usability •  “Build  once,  run  anywhere”   –  Automated  transla@on  of  VMs   allows  users  to  share  VM  images   easily  between  different  Cloud   OSs.   –  It  achieves  the  desired  scale  out  of   Cloud  infrastructure  by  federated   use  of  supercomputers.
