ORNL Workshops Focus on Cray XT, Lustre

March 6 -- Computational scientists will gather at Oak Ridge National Laboratory (ORNL) in April to hone their skills with the Cray XT supercomputer and the Lustre file system.

ORNL's Jaguar supercomputer is among the world's most powerful XT systems, and the April 14-16 XT Workshop will give computational scientists a unique opportunity to meet with XT experts. The workshop is sponsored jointly by ORNL's National Center for Computational Sciences (NCCS) and the National Institute for Computational Sciences, home to the National Science Foundation's newest supercomputer dedicated to transformational science.

At the workshop, researchers will join in hands-on sessions and extensive discussions with staff from the two centers and experts from Cray and chipmaker AMD. Discussions will focus on getting the most out of AMD quad-core processors and the XT architecture, with specific topics including the use of mixed MIP/OpenMP and measurement of application performance on the system.

In addition, the NCCS and Sun Microsystems will host an all-day workshop April 16 on the state-of-the-art Lustre file system.

The workshop will be presented by Oleg Drokin and Wang Di, file system engineers with Sun who are seasoned Lustre developers. A morning session will discuss strategies for improving application I/O performance, including ongoing enhancements to I/O middleware libraries such as MPI-IO and HDF5. The afternoon will feature an open discussion on application I/O with Lustre. Users will get a chance at this session to discuss their applications with Lustre engineers and get advice on improving performance. They will also have an opportunity to discuss the I/O needs of future applications, including ways in which Lustre can better address user requirements.

Registration is being taken for both workshops. For more information, visit http://www.nccs.gov/user-support/training-education/workshops/nccs-users-meeting-and-xt-workshop/.
