  30. XC Software Stack Overview HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  31. Cluster system management Objective • XC Installation • Provide an automated installation with minimal user interaction • Provide a default installation for the user • Provide for easy and repeatable installations • XC Configuration • Provide initial cluster configuration and subsequent run-time updates of all nodes • Provide for maximum automation, and minimal user-intervention • Provide for easily and readily repeatable configurations • XC Monitoring • Monitoring of both system performance metrics like CPU and memory utilization, as well as environmental data such as fan, temperature, and power-supply status • Parallelized service checks • scalable logging facility HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  32. SystemFiles HeadNode SystemImagerGolden Client XCDistribution XCDB AdminNetwork Kickstart SystemImagerPropagation SystemFiles HeadNode XC Installation • Distribution • Distribution delivered on one DVD • Default Kickstart file included on DVD • Discovery • Initial cluster discovery • All required configuration data gathered up front, via simple UI • Configuration data written to system database, for subsequent retrieval by various utilities • Head node configuration • User-chosen roles, plus typically setup as initial DHCP server, DB server • Node replication environment (systemimager) configured • “golden client” • Image server HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  33. XC Configuration • Nodeconfiguration • All other nodes are image installed in a two phase process • Phase-1: node is generically imaged • Phase-2: per-node personality is applied using configuration data from either from a cached DB copy sent with each image. • At the end of this process, all nodes have been rebooted, and configured with their respective personality • Local copy of Linux on each node allows for very scalable fast booting. • Large machine should boot in less than half an hour • Actual node booting • Starting of services – slurm, nagios, syslog-ng • Mounting of SFS file systems HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  35. XC Monitoring - Nagios • An open source host, service and network monitoring program • The monitoring daemon runs intermittent checks on hosts and services specified for XC using external "plugins" which return status information to Nagios. • When problems are encountered, the daemon can send notifications out to administrative • Current status information, historical logs, and reports can all be accessed via a web browser HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  36. SystemFiles Nagios HeadNode XCDB Syslog-ng Supermon Nagios AdminNetwork XC Monitoring HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  41. XC Resource Management • SLURM and LSF • Scalability • Handling of STDIO, signals, etc… • LSF is a scheduler which manages the user workload. • SLURM allocates the cluster resources for use by LSF. HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  42. What is SLURM ? • Simple Linux Utility for Resource Management • Arbitrates requests by managing queue of pending work • Allocates access to computer nodes within a cluster • Launches parallel jobs and manages them (I/O, signals, limits, etc.) • NOT a comprehensive cluster administration or monitoring package • NOT a sophisticated scheduling system • An external entity can manage the SLURM queues via plugin HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  43. Why SLURM ? • Simple • Scheduling complexity external to SLURM (LSF, PBS) • Open source: GPL • Fault-tolerant • For SLURM daemons and its jobs • Secure • Restricted user access to compute nodes • System administrator friendly • Simple configuration file • Scalable to thousands of nodes HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  46. What is the “Top 500”? • International register of worlds fastest supercomputers • Located at http://www.top500.org • Updated twice per year (June & November) • Position based on Linpack results (Rmax not Rpeak) • #1 is currently 136.8 Tflops (65536 IBM P4 processors!) • #500 is currently 1.166 Tflops • HP first entry number 12 (LANL at 13.88Tflops) • 26.2% of entries are HP. HP is no 2 for entries. • HP & IBM total 78% of list • Very important to some customers ! HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  47. What is a Flop? • Floating Point OPerations per second • industry standard for measuring a servers raw floating point mathematical power • Flops=(speed in hz) x (# of CPU) x (floating point operations per cycle) • Xeon & Opteron (2 ops per cycle) Itanium (4 ops per cycle) • For example a dual 3.2Ghz processor DL360 equates to 3.2Ghz x 2cpu x 2 operations = 12.8Gflops Rpeak • A Gigaflop is 1000,000,000 flops • A Teraflop is 1000 Gflops • Rating of cluster = node Rpeak x number of nodes • The formula gives theoretical (Rpeak) performance only HP XC Cluster = A simple, scalable, and flexible Linux cluster solution

  48. What is linpack? • The Linpack Benchmark is a measure of a computer’s floating-point rate of execution • It is determined by running a computer program that solves a dense system of linear equations • The benchmark result gives us the Rmax of the cluster • Rpeak (theoretical) divided by Rmax (actual) gives us the cluster efficiency • Results are effected by many things including: • Processor architecture • Server architecture • Available memory • Interconnect speed & latency • Compiler efficiency • Maths library efficiency • Etc … HP XC Cluster = A simple, scalable, and flexible Linux cluster solution
