                         Performance Computing

E-mory
Li-fe
P-hysical
S-ciences cluster.
Information Technology

    What does High Performance Computing
                (HPC) mean?

 Computing used for scientific research
 A.k.a, “Supercomputing”
 Highly calculation-intensive tasks (e.g.,
  weather forecasting, molecular modeling,
  string matching)
Information Technology


             What is an HPC cluster?

 A (large?) collection of computers,
  connected via high speed network or fabric
 Sometimes acts/viewed as one computer
 Sometimes share common storage
 Sometimes run identical instances of the
  same operating system
 Definition of cluster is fluid
Information Technology


        What is an HPC cluster, again?

 Uses multiple CPUs to distribute
  computational load, aggregate I/O.
 Computation runs in parallel.
 Not necessarily designed for fail-over, High
  Availability (HA) or load-balancing
 Different from a Grid
 Work managed via a “job scheduler”
Information Technology


          Our new cluster (overview):

 256 dual-core, dual-socket AMD Opteron-
  based compute nodes - 1024 cores total
 8 GB RAM/node, 2 GB RAM/core
 250 GB local storage per node
 ~ 8 TB global storage (parallel file system)
 Gigabit Ethernet, with separate
  management network
 11 additional servers
Information Technology


                  Cluster diagram
Information Technology


                   Cluster Picture
Information Technology


         Our cluster: Compute Nodes

 256 Sun x2200s
 AMD Opteron 2218 processors
 CentOS 4 Linux (whitebox Red Hat)
 8 GB DDR2 RAM, except “Fat” Nodes with
  32 GB RAM, local 250 GB SATA drive
 Single gigabit data connection to switch
 Global filesystem (IBRIX) mounted
Information Technology


             Our cluster: Networking

 Separate Data and Management networks
 Data Network: Foundry BI-RX 16
 Management network: 9 Foundry
  stackables
 MRV console switches
 Why ethernet? Open, supported, easy,
  cheap.
Information Technology


      Our cluster: Cluster-wide Storage

 Global, parallel file system: IBRIX
 Sun StorEdge 6140, five trays of 16
  15Krpm FC drives, connected via 4 GB fibre
  connections.
 Five Sun x4100 file-system servers: one
  IBRIX Fusion Mgr, four Segment servers
  w/four bonded ethernet connections.
Information Technology


              The IBRIX file system

 Looks like an ext3 file system, because it is
  (not NFS 4) - Segmenting ext3.
 Scales (horizontally) to thousands of
  servers, hundreds of petabytes
 Efficient with both small and large I/O
 Partial online operation, dynamic load
  balancing
 Will run on any hardware (Linux only)
Information Technology


       The Scheduler: Sun Grid Engine
 Users submit work to cluster via SGE
  („qsub‟ command)and ssh
 SGE can manage up to 200,000 job
  submissions
 Distributed Resource Management (DRM)
 Policy-based resource allocation algorithms
  (queues)
Information Technology


                Cluster-based Work

 Cluster designed as “beowulf-style”, for
  high-throughput “serial/batch” processing.
 “Embarrassingly Parallel” jobs best
 MPI-based parallel processing possible, but
  difficult due to multiple-core architecture
Information Technology


                     Applications

   MATLAB
   Geant4
   Genesis (Neuroscience)
   Soon: iNquiry (BioInformatics)
   Gcc compilers (soon: PGI compilers)
   More…
Information Technology


                    Performance
 Estimated ~3 Teraflops at 80% efficiency
  (theoretical)
 Achieved 2 GB/sec writes over the network
 10 minutes of cluster operation = ~7 days
  on a fast desktop
 8.5 hours -> entire year of 24-hour days
Information Technology


                    Project Status
 Cluster went “live” July 1st
 We are converting over billing
  arrangements: Annual -> $/CPU hour
 Software installation, hardware
  replacement, developing processes
 Much testing…
