DESCRIPTION:I will talk about the design and implementation of FaRM\, a ne
 w main memory distributed computing platform that exploits RDMA communicat
 ion to  improve both latency and throughput by an order of magnitude relat
 ive to state of the art main memory systems that use TCP/IP. FaRM exposes 
 the memory of machines in the cluster as a shared address space. Applicati
 ons can allocate\, read\, write\, and free objects in the address space. T
 hey can use distributed transactions to simplify dealing with complex corn
 er cases that do not significantly impact performance. FaRM provides good 
 common-case performance with lock-free reads over RDMA and with support fo
 r collocating objects and function shipping to enable the use of efficient
  single machine transactions. FaRM uses RDMA both to directly access data 
 in the shared address space and for fast messaging and is carefully tuned 
 for the best RDMA performance. We used FaRM to build a key-value store and
  a graph store similar to Facebook's. They both perform well\, for example
 \, a 20-machine cluster can perform 160 million key-value lookups per seco
 nd with a latency of 31micro-seconds.
