  • Scalable load-balancing for large-scale big data applications Motivations Increasing supercomputer power 2008 Blue Gene/P Intrepid system 40,960 nodes 163,840 processor cores 2011/12 Blue Gene/Q Sequoia system 98,304 nodes 1.6 million processor cores "Unlimited" resources in cloud computing Big Data
  • Scalable load-balancing for large-scale big data applications Questions Can centralized systems handle the load? What about decentralized systems? Are distributed systems required?
  • Scalable load-balancing for large-scale big data applications Many applications and solutions are available. We will start with MapReduce. Apache Hadoop implementation (2005) Open Source (Apache top-level project) Useful in a wide range of applications Global community of users and contributors Commercial support for companies Sponsors: Yahoo!, Google, HP, IBM, Facebook, ...

  • MapReduce Paradigm 2004 by Google
  • MapReduce Paradigm function map(String name, String document): // name: document name // document: document contents for each word w in document: emit (w, 1) function reduce(String word, Iterator partialCounts): // word: a word // partialCounts: a list of aggregated partial counts sum = 0 for each pc in partialCounts: sum += ParseInt(pc) emit (word, sum)
  • Hadoop v1
  • Hadoop v2 (YARN)
  • Hadoop v1 vs v2 Pros Job Tracker was split Resource Manager (RM) Application Master (AM) As many AMs as jobs 5k nodes in 2009 to 10k in 2012 Same price = 2x resources RM and AM are still centralized components
  • Research Study scalability in Hadoop v1, v2 Experiments Understand scalability gains in YARN Scalability limits Model centralized components overhead Predict scalability limits by simulation Conceive and simulate an alternative solution
