Status of accelerated computing in Clouds

Need modification/support at all levels


  • Chipset : HW virtualization support (otherwise some limitation)
  • OS level: correct kernel configuration for the accelerators
  • Hypervisor: configuration pass-through, vGPU
  • CMFs: VM start, scheduler
  • FedCloud facilities: accounting, information discovery
  • Application: VM images with correct drivers for specific chipsets


Accelerators

GPGPU (General-Purpose computing on Graphical Processing Units)

NVIDIA GPU/Tesla/GRID, AMD Radeon/FirePro, Intel HD Graphics,...

Virtualization using VGA pass-through, vGPU (GPU partitioning) - NVIDIA GRID accelerators

Intel Many Integrated Core Architecture

Xeon Phi Coprocessor
Virtualization using PCI pass-through

Specialized PCIe cards with accelerators

DSP (Digital Signal Processors)
FPGA (Field Programmable Gate Array)
Not commonly used in cloud environment

Hypervisors

QEMU/KVM

Supports only pass-through virtualization model
vGPU support is under development

Citrix XenServer 6, VMware ESXi 5.1

Support both pass-through and vGPU virtualization models

Limitations:

  • vGPU support require certified server HW
  • Live VM migration is not supported
  • VM snapshot with memory is not supported
