Video: Accelerating OpenPOWER Using NVM Express SSDs and CAPI

openpowerIn this video from the GPU Technology Conference, Stephen Bates from CSTO, PMC-Sierra presents: Using NVM Express SSDs and CAPI to Accelerate Data-Center Applications in OpenPOWER Systems.

NVM Express is a standards based method of communication with PCIe attached Non-Volatile Memory. An NVM Express open-source driver has been an integrated part of the Linux kernel since March 2012 (version 3.3) and allows for very high performance. Currently there are NVM Express SSDs on the market that can achieve read speeds of over 3GB/s. We present results for a platform consisting of an NVM Express SSD, a CAPI accelerator card and a software stack running on a Power8 system. We show how the threading of the Power8 CPU can be used to move data from the SSD to the CAPI card at very high speeds and implement accelerator functions inside the CAPI card that can process the data at these speeds. We discuss several applications that can be serviced using this combination of NVMe SSD and CAPI.”
