DESCRIPTION:By: Naama Ben-David - VMWare\nIC Faculty candidate\n\nAbstract
 \nDue to the end of Moore’s law\, hardware has been developing more rapi
 dly in recent years than it has at any point since the early days of compu
 ting. These hardware developments are trending toward multiprocessor setti
 ngs\, which have the potential to deliver the speedups that CPU frequency 
 scaling can no longer support. However\, without a principled way of reaso
 ning about these new settings\, systems built on top of them may not enjoy
  the benefits they promise\, and in fact\, such systems may even suffer du
 e to the increasing complexity of their underlying hardware.\n\nIn this ta
 lk\, I will discuss my work on building theoretical foundations for emergi
 ng multiprocessor technologies. I will focus on one line of work that conc
 erns a data center communication primitive called Remote Direct Memory Acc
 ess (RDMA). RDMA allows accessing the memory of a remote machine without i
 nvolving its CPU\, and has become widely adopted in recent years due to it
 s performance advantages. I’ll present the first theoretical model that 
 captures RDMA’s capabilities\, and use it to show that RDMA is more powe
 rful than previous communication technology. I’ll then present the desig
 n of a state machine replication system based on those theoretical insight
 s that improves previous state-of-the-art latency both in failure-free exe
 cutions (by over 2x) and in failure recovery (by over 10x).\n\nBio\nNaama 
 Ben-David is a postdoctoral researcher at VMware. She completed her PhD at
  Carnegie Mellon University\, where her dissertation received an honorable
  mention for the CMU SCS Dissertation Award. Her primary research interest
 s are in the intersection of theory and practice in distributed and concur
 rent computing. More specifically\, Naama strives to theoretically explain
  phenomena seen in modern machines\, and to use obtained insights to desig
 n and analyze practical algorithms for multiprocessor settings. Naama is t
 he recipient of an NSERC postgraduate scholarship and a Microsoft Research
  PhD Fellowship.\n\nMore information\n\n
