motivation
Motivation
  • Proliferation of cores
    • CPUs
    • GPUs
    • Network cards
    • RAID controllers
overall vision
Overall Vision
  • Applications written in platform neutral code
  • OS leverages the available hardware cores, placing application on most appropriate device
  • Provide an environment for safe 3rd party applications on devices
  • Enable new and interesting applications

singularity
Singularity
  • Microkernel design
  • Kernel and applications written in managed code (variant of c#)
  • Type checking and static verification used to ensure process isolation
  • No explicit shared memory between processes
singularity inter process comms
Singularity Inter-Process Comms
  • A Singularity process has only 2 communication mechanisms
