Beginning Saturday, October 8th, the NCAR Colocation Data Center will be shut down to facilitate standard cooling plant maintenance. Operations begin @ 06:00 on October 8th and are scheduled to end @ 18:00 on October 8th. Program system administration teams have been provided details on the work taking place. If you have questions regarding impacts to your program, check with your system administration team. If you require additional information send your questions to: cislhelp@ucar.edu.

CISL Service Outage Information:

  • NETS MLDC 10G Ethernet switches will lose connectivity while NETS reconfigures ml-mr-j1-es.  All other  Ethernet switches in the MLDC and in other areas of the Mesa Lab will remain up and connectivity will be available.  The work on ml-mr-j1-es affects ml-mr-j2-es, ml-mr-j3-es, ml-mr-c7-gs, ml-mr-c9-gs, and ml-mr-c5-gs. The planned window for this work is 6:30 a.m. to 8 a.m.
  • —DNS: Internal DNS servers at ML are expected to remain up except for dnsi1 (128.117.64.44). External DNS servers at ML will be temporarily unavailable between 6:30-9am and dnsx1 (192.43.244.39) will remain down for the duration of the power down. DNS master servers, the remaining slave servers, and DNS servers at NWSC will remain up. DNS interruptions and slowness should be minimal assuming devices are configured to also resolve DNS queries with other servers. Infoblox hosted DNS and DHCP will failover to the NWSC node.
  • The license servers for Mathematica and the PGI compilers will be down. However, Matlab on Yellowstone WILL NOT be affected because it uses a different license server for Matlab.
  • —UCAR web services: jira, drupal sites and wiki.ucar.edu will be down.
  • —ExtraView (CISL Help Desk ticketing system) will be down. - Please contact CASG at x4300 or 307-996-4300.
  • ML Active Directory Domain Controller: Windows CIT domain authentication should remain unaffected as two other domain controllers at different sites will be up.
  • Cisco Anyconnect VPN will remain up, but without redundancy.
  • colopower.ucar.edu - Will be unavailable from 06:30 - 08:00.
  • The CrashPlan backup service will be down during this time for both internal and external use

Services that will be offline between 6:30 and 9am:

  • UCAS Password Changes via web: Changing UCAS passwords will be unavailable via the web at https://kpasswd.ucar.edu/ but will remain available on Kerberized workstations. UCAS password authentication, Role Principal initiation, and Role Principal authentication will remain in service.
  • UCAS Token Authentication: The external radius server at ML will be down and therefore systems configured to the external radius server will not allow token authentication (yubikey and cryptocard) to work until service is restored after the networking work is completed in the morning. This should not affect most staff and university users.
  • The Mailman system, and mail to a few mailboxes inside UCAR, will be down, but will be returned to service after networking work is completed.
  • External DNS: ML External DNS service will be temporarily offline during this time window.

A Geostatistical Approach to Modeling Teleconnections
Josh Hewitt
Colorado State University

We present a geostatistical method for studying teleconnections at regional scales by extending hierarchical Bayesian spatial models to incorporate predictor variables that are spatially remote from response variables.  Our method uses remote large scale predictors, such as sea surface temperatures (SSTs), to predict local variables, like precipitation.  The method uses spatially varying coefficients so that teleconnection effects are localized, allowing the model to capture the varying impacts that large scale predictors have on different regions.  Hierarchical Bayesian frameworks also facilitate testing the significance of teleconnection effects and for quantifying forecast uncertainties.  We present encouraging preliminary results of using this method with seasonal sea surface temperatures to study regional teleconnections and to predict seasonal precipitation in Colorado and Oklahoma.  This is joint work with Jennifer A. Hoeting (CSU), James Done (NCAR), and Erin Towler (NCAR).

Optimizing Compilers for High-Performance Computing
Dr. Louis-Noël Pouchet
Assistant Professor, Colorado State University

Applications running on clusters of shared-memory computers are often implemented using OpenMP+MPI. Productivity can be vastly improved using task-based programming, a paradigm where the user expresses the data and control-flow relations between tasks, offering the runtime maximal freedom to place and schedule tasks. While productivity is increased, high-performance execution remains challenging: the implementation of parallel algorithms typically requires specific task placement and communication strategies to reduce inter-node communications and exploit data locality. Furthermore, pattern-specific and target-specific code optimizations are often needed to achieve high-performance execution of task bodies.

In this talk we present a new macro-dataflow programming environment for distributed-memory clusters, based on the Intel Concurrent Collections (CnC) runtime. Our language extensions let the user define virtual topologies, task mappings, task-centric data placement, task and communication scheduling, etc. We introduce a compiler to automatically generate Intel CnC C++ run-time, with key automatic optimizations including task coarsening and coalescing. We also present several pattern-specific optimization scenarios, including our latest results on optimizing stencil computations on regular grids.

Bio:

Dr. Louis-Noel Pouchet is an Assistant Professor at Colorado State University. He is working on pattern-specific languages and compilers for scientific computing, and has designed numerous approaches using optimizing compilation to effectively map applications to CPUs, FPGAs and SoCs.  His work spans a variety of domains, including compiler optimization, hardware synthesis, machine learning, programming languages, and distributed computing. His research is currently funded by the National Science Foundation, the Department of Energy, and Intel.  Previously he has been a Visiting Assistant Professor (2012-2014) at the University of California Los Angeles, where he was a member of the NSF Center for Domain-Specific Computing, working on both software and hardware customization. He is the author of the PolyOpt and PoCC compilers, and of the PolyBench/C benchmarking suite.

Heavy and persistent precipitation in a quasi­stationary convective system in SW England

 Alan Blyth

National Centre for Atmospheric Science, University of Leeds.

 

Observations were made with three aircraft, a ground­based X­band radar and several other ground­based instruments during the COnvective Precipitation Experiment (COPE) in the southwest peninsula of England during the summer of 2013.  Convergence lines form in the region as a result of colliding sea­breeze fronts.  Convective clouds often develop along the lines that occasionally results in flash flooding. The most infamous recent example occurred in Boscastle in August 2004. The flash floods and convergence lines have been studied using models and the UK Met Office (MO) network radars and rain gauges, but observations of the microphysics and dynamics of the systems were never made until COPE.

Modelling results and observations will be presented in this talk of a quasi­stationary convective system on 3 August 2013 that had some similarities to the Boscastle case. Heavy precipitation persisted for several hours in localised regions, although a flash flood did not occur. The measurements on this day were made with two aircraft (University of Wyoming King Air and UK BAe 146), a mobile radar, the MO network of radars and ground­based aerosol instruments.  The mobile radar is a dual­polarisation Doppler X­band radar. It made PPIs with a volume return time of about 5 minutes.  The WRF model run at 400­m resolution and a detailed microphysics model were used to help interpret the observations. The warm rain process, supercooled raindrops, graupel and multiple thermals appear to be key to the intensity and persistence of the precipitation
