LinuxCon and CloudOpen North America, 2013: 

Intel MIC X100 is a PCIe form factor add-in coprocessor card based on the Intel Many Integrated Core (MIC) architecture that runs a Linux OS. We provide an overview of the SW stack for this device and details on the Linux driver. The driver provides a IPC and RDMA API for HPC applications/libraries and reuses the virtio drivers for networking, storage and console services. We would very much like to see a common OS subsystem to handle such computing devices and our attempt is a first step in that direction. As such we have tried to reuse common Linux idioms in the APIs and the driver for a class of devices that is rather uncommon, though the presentation would be of specific interest to driver developers working in the areas of PCIe, HPC fabrics,   Compute Coprocessors etc. We hope this presentation revives the discussion of infrastructure support for PCIe endpoints that run Linux.
