InteGrade 2002 - 2011 Object-oriented grid middleware Opportunistic My final work for undergraduation Grid Computing Resource Management - Node Control Center, 2009 Limit CPU usage on the client-side Web interface (C++) InteGrade Node Control Center Multi-core CPU affinity Brazil Brazil 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, ... So Paulo - Liberdade 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 Related Works - MTC Falkon (2007) Less features 487 vs 11 tasks/sec in Condor (2004) MATRIX (2013) Fully distributed Work-stealing leads to better efficiency (18-82% to vs 92-97%) CloudKon (CCGrid 2014) Based on cloud services (IaaS and SaaS) The only one to support 256 VMs (up to 1024) Blames too many open TCP connections Related Works - MTC Proposal Less functionalities Distributed selfish load balancing by Adolphs & Berenbrink No global information Less open connections -approximate NE convergence in O(ln (m/n)) Mathematically guaranteed to be fast Scalable Can deal with different speeds, weights Data-awareness Progress Measuring Hadoop v1 and v2 latency HiBench suite Nuvem USP Cloud up to 64 VMs Experiments automatization with Python VM Management Hadoop Management Monitoring Log parsing Graphs Deadline: qualifying exam in August The End Thank you!
