• Maia system in production: 18 Jun 2013
  

  Maia, a 32-core, 128GB RAM system (2 x AMD Opteron 6380, 2.5GHz), was placed in service on June 18, 2013. All Lehigh University students, faculty and staff may request an account for work on Maia. For details on using Maia, please consult new documentation (available on-campus or via VPN) at the Research Computing wiki. In particular, please review the article for Polaris on the wiki; this is the system to which SSH connections are made to submit jobs for Maia.

   
  
• LEAF and Altair systems to be decommissioned July 1, 2013
  

  Both LEAF and Altair will be removed from service on July 1, 2013; these systems are functionally obsolete.

  Maia, a 32-core, 128GB RAM system (2 x AMD Opteron 6380, 2.5GHz), will be placed in service on June 18, 2013, replacing the current “no-cost” LEAF and Altair systems. All Lehigh University students, faculty and staff may request an account on Maia. All computing tasks on Maia (including interactive shell sessions) will be managed via a scheduling server named Polaris. No use of graphical user interface (GUI) programs will be supported on Maia. Some GUI-based programs provide for command-line use; these components will be supported on Maia.

  For full details, including details on migration to Maia and action items for current LEAF and Altair users, please see the announcement (PDF).

   
  
• COMSOL workshop June 13, 2013, 1-4PM, Grace Hall Rm 28.
  The first half of this workshop provides an overview of COMSOL Multiphysics: its capabilities, functionality, features, and graphical user interface. A live demonstration will offer a fundamental base for working with COMSOL. We will examine the Model Builder which provides great functionality to efficiently modify and adapt models. A simulation example will be shown, demonstrating both the speed and ease of the work flow.
   
  The second half of the workshop is a hands-on tutorial in COMSOL Multiphysics. It is directed at both new users and existing users who would like experience with the new interface. We will set up and solve a simple multiphysics problem designed to make participants quickly proficient in COMSOL Multiphysics - enabling the participants to use the included 2-week free trial on their own models. Attendees should bring their own laptop system to participate in the hands-on tutorial.

• 2013 Lehigh HPC Symposium: Apr 11-12, 2013
  Registration for the 2013 Lehigh University High Performance Computing Symposium is open at hpcsymposium.lehigh.edu. On the afternoon of April 11, there will be two presentations on the efficient use of Lehigh University HPC resources, and details on the National Science Foundation XSEDE supercomputing program resources available to Lehigh students, faculty and staff. On Friday, April 12, we will host a full slate of talks by visiting researchers in a broad range of disciplines.
  For details and to register, please visit hpcsymposium.lehigh.edu.
  
  
• Videoconference Course: Supercomputing in Plain English
  Tuesdays, 3 p.m. (EST) EWFM Library, room 625
  Jan 22, 2013 through Apr 30, 2013. No meeting Mar 19, 2013.
  
  Schedule, prerequisites and links to previous years' materials at the SiPE course website.
  
  Free course; register with Henry Neeman, Director of the University of Oklahoma's OSCER, indicating that you'll be attending videoconference from Lehigh University. Please send an additional email to hpc@lehigh.edu so that we have an accurate local head count for the videoconference room.
  

  SiPE is targeted at an audience of not just computer scientists but especially scientists and engineers, including a mixture of undergraduates, graduate students, faculty and staff.
  
  These workshops focus on fundamental issues of HPC as they relate to Computational and Data-enabled Science & Engineering, including:
  
  

  • the storage hierarchy
  • instruction-level parallelism
  • high performance compilers
  • shared memory parallelism (e.g., OpenMP)
  • distributed parallelism (e.g., MPI)
  • HPC application types and parallel paradigms
  • multicore optimization
  • high throughput computing
  • GPGPU computing
  • scientific and I/O libraries
  • scientific visualization

  
  The key philosophy of the SiPE workshops is that an HPC-based code should be maintainable, extensible and, most especially, portable across platforms, and should be sufficiently flexible that it can adapt to, and adopt, emerging HPC paradigms.
