[intrepid-notify] ALCF Weekly Updates - April 19

[ALCF User Services]

*** Access T&D Blue Gene/Q Rack at Leap to Petascale Workshop May 22-25***
Mark your calendars and plan to attend Leap to Petascale: Making the Move to Mira. This workshop is geared especially for current INCITE and discretionary projects that have already scaled to multiple racks of Intrepid. With the arrival of Mira, the ALCF's 10-petaflops Blue Gene/Q, this year's workshop will focus on issues of scaling to the next-gen system. The workshop is also timed to coincide with efforts of teams preparing to submit 2013 INCITE proposals. A significant portion of workshop time will be devoted to hands-on tuning of applications with one-on-one assistance from our performance engineers and computational scientists. Special system reservations will provide the opportunity for full-scale runs and participants will have access to our test and development rack of Blue Gene/Q. Visit https://www.alcf.anl.gov/workshops/l2p-workshop to register. 

*** "Preparing for INCITE" Webinar April 24. Register Now! *** 
The open call for 2013 INCITE awards is April 11-June 27, 2012. To be eligible for an INCITE award, your project must demonstrate a high-impact science goal, plus computational readiness and the need for leadership-class supercomputing resources. Visit https://www.alcf.anl.gov/incite2013 to find out more about the INCITE Program and to register for this informational webinar.

*** Maximize Code Performance Using MPI Environment Variables ***
Learn how to maximize the performance of your code using MPI-related environment variables. Over the next few weeks, we will describe some of the most useful options for tuning MPI point-to-point and collective protocols, both to maximize communication speed and minimize memory usage. This week, we consider DCMF_EAGER and provide an example where using a non-default value reduces wall time by more than an order-of-magnitude. Visit http://www.alcf.anl.gov/resource-guides/tuning-mpi-bgp to read more.

*** Updated IBM XL Compilers Now Available ***
The April 2012 updates of the IBM Blue Gene/P compilers are now available (XL C/C++ version 09.00.0000.0014 and XL Fortran 11.01.0000.0014). To select the new version, use the softenv key @ibm-compilers-apr2012. See http://www.alcf.anl.gov/faq-page/how-do-i-select-xl-compiler-versions for detailed instructions. Please compile your application code with the update and report any problems. This version will become the default on Surveyor beginning April 30, and on Intrepid and Challenger beginning May 21.

*** SC12 Extends Deadlines for Technical Program Submissions ***
The SC12 technical program committee has extended by one week the deadlines for submitting technical papers, entries for the ACM Gordon Bell Prize, proposals for tutorials, panels and workshops, and abstracts for the SCinet Research Sandbox. The deadline for abstracts for technical papers and ACM Gordon Bell Prize has been extended to Friday, April 27. Full submissions for technical papers and ACM Gordon Bell Prize are now due Friday, May 4. The deadline for abstracts for the SCinet Research Sandbox has also been extended to Friday, May 4, with full proposals due June 1. All submissions are being accepted now at https://submissions.supercomputing.org/. Visit http://sc12.supercomputing.org/content/important-dates for a complete list of SC12 program deadlines.
