 n University\nIC Faculty candidate\n\nAbstract:\nFunction-as-a-Service "se
 rverless" platforms like Amazon Lambda have quickly emerged as a popular e
 nvironment for developers since their arrival in 2014. FaaS offers develop
 ers automatic scaling of their applications with user demand and the promi
 se to only pay for the resources their application uses\, down to the mill
 isecond range. Despite its desirability and positive features\, FaaS has i
 ts dirty secrets. In this talk\, I will reveal how the paradigm disregards
  decades of architectural wisdom and rewards misbehaviour from the FaaS pr
 ovider. These issues require a rethink of the hardware and software stack 
 to make today's markets more efficient and to enable the applications of t
 omorrow that will make FaaS shine in the post-Moore era.\nTo prototype the
 se changes\, we need to build full-stack prototype systems ready to run co
 mplex virtualised or containerised applications like FaaS\, as high-level 
 simulation alone abstracts away the complex system interactions. I will in
 troduce OpenPiton\, our open-source manycore research platform used to eva
 luate architecture research ideas for the cloud and beyond. OpenPiton enab
 les the exact kind of full-stack system-on-chip prototyping we need in a p
 ush-button way\, making it ideal for evaluating serverless applications an
 d future research ideas. By embracing open-source hardware\, the platform 
 reduces the barrier to entry for new users across Computer Science and Ele
 ctrical Engineering and creates a nexus where research ideas can come toge
 ther to build a single coherent system.\nOne example of such a system I wi
 ll introduce is our "Bring Your Own Core" (BYOC) platform for enabling het
 erogeneous-ISA systems research. BYOC enabled the development of both the 
 first open-source\, general-purpose\, heterogeneous-ISA processor and the 
 first open-source\, SMP Linux-booting RISC-V manycore. By providing our no
 vel interface for the connection of processor cores\, one can bring a core
  of their choice and turn it into a heterogeneous manycore system with min
 imal effort. With this we have built multiple heterogeneous-ISA prototypes
  and connected ten cores of ISAs including RISC-V\, X86\, and SPARC. BYOC 
 brings the potential to break down the ISA barrier\, treating it as "just 
 another interface" in the broader system stack\, and to enable a new class
  of application-optimised heterogeneous systems to live alongside emerging
  application-specific accelerators.\n\nBio:\nJonathan Balkind is a PhD Can
 didate in Computer Science at Princeton University. His research interests
  lie at the intersection of Computer Architecture\, Programming Languages\
 , and Operating Systems. He is the Lead Architect of OpenPiton and its het
 erogeneous-ISA descendent\, BYOC\, which are productive research platforms
  with thousands of downloads from over 70 countries worldwide. In developi
 ng Piton (a 25-core OpenPiton ASIC)\, Jonathan's verification effort helpe
 d ensure a functional\, Linux-booting chip\, a notable accomplishment for 
 a small academic team's first chip. Jonathan was also a developer of FaaSP
 rofiler\, a tool for profiling Function-as-a-Service "serverless" applicat
 ions. His research on FaaS unveiled a series of architectural problems wit
 h today's FaaS workloads which will only be effectively addressed through 
 hardware-software co-design. Jonathan was a Class of 2018 Siebel Scholar a
 nd recipient of the Gordon Y.S. Wu Fellowship in Engineering. He received 
 his Master's in Science in Computing Science with Honours of the First Cla
 ss from the University of Glasgow in June 2013. He has completed internshi
 ps at Samsung Electronics (Suwon\, South Korea)\, Arm Ltd (Cambridge\, UK)
 \, and Microsoft Research (Cambridge\, UK).\n\nMore information
