April “Code for Q” Workshop – have you registered yet?

The April ESP “Code for Q” workshop will be held April 30 – May 2, 2012.

If you plan to attend, please register using instructions emailed to you (if you lost or didn’t receive instructions, email [email protected] or [email protected] and we’ll send them to you). Registration deadlines:

April 16 – Non US citizens (who are not ANL employees)
April 23 – US citizens and ANL employees

This workshop will start at 1:00 pm on Monday 30 April, with a full afternoon of formal presentations about Blue Gene/Q hardware and software, and our Very Early Access System 1-rack Blue Gene/Q machine you’ll have access to. Tuesday and Wednesday May 1-2 will be all-day hands-on sessions, with mini-presentations by some tools and libraries teams about their efforts on BG/Q and how to use their software on VEAS if available. Developers from these tools and libraries teams will be available to help you use their software, and ALCF staff will be on hand to help you get your code ported and running on VEAS.

One-Rack BG/Q System – VEAS

Developers from the Early Science projects (and Tools & Libraries project) are eligible for accounts on the ALCF’s new one-rack BG/Q system, in its current form as the Very Early Access System (VEAS). If you would like to get access, please email [email protected] or follow the new instructions for requesting the VEAS resource.. The VEAS is currently living on the test & development rack named cetus.

(The system software and compilers on the VEAS are pre-production. There have been, are, and will continue to be glitches, unplanned downtimes, and software updates. In exchange for early access, you must agree to be tolerant of this environment.)

March “Code for Q” Workshop Held

The ESP March 2012 Workshop, “Code for Q,” was held at the ALCF. We had 57 attendees, with representatives from 13 of the 16 ESP projects and several teams under the Tools and Libraries project. After an afternoon of formal presentations on Monday March 19th, we had two days of mostly hands-on work. By the end of the workshop, several ESP scientific applications and several tools/libraries packages were running on our one-rack BG/Q system, the VEAS (Very Early Access System).

March “Code for Q” Workshop – have you registered yet?

If you plan to attend the March ESP workshop, please register using instructions emailed to you (if you lost or didn’t receive instructions email [email protected] or [email protected] and we’ll send them to you). Registration deadlines:

  • March 5 – Non US citizens (who are not ANL employees)
  • March 12 – US citizens and ANL employees

If you are a non-US citizen and not an Argonne employee, the registration deadline has passed. You should consider coming to the 2nd workshop, whose dates are now set as April 30 – May 2.

Upcoming Workshops – March Dates Moved to 19-21

As discussed in a recent email to ESP investigators, the ALCF is planning a couple of workshops for the Early Science Program. The first was tentatively scheduled for March 5-7, but because of a conflict in our conference center is being rescheduled for March 19-21.

These are meant to be primarily technical, hands-on workshops for informal sharing of information and expertise; ALCF staff will help to get your code better target to Blue Gene/Q. By the time of the first workshop, we should all have access to the new test & development machine (a one-rack system that is currently being built at the ALCF). A practical goal of the workshops it getting your codes built and running on the T&D system. The 2nd workshop is planned for April–dates TBA.

Notes from SC11 – Blue Gene/Q details public

Last night, IBM made a big announcement about Blue Gene/Q on the exhibit floor at SC11 in Seattle. Today, they are presenting a couple of papers and otherwise publicizing BG/Q. This means the lifting of the nondisclosure requirement for details of BG/Q hardware, software, and performance. I will be giving a presentation at the Argonne booth at SC on Wednesday at 11:30, which will discuss preparing applications for Mira. This will include some early performance numbers from the various ESP projects, and performance numbers for codes used as part of our contract with IBM—many of which are used by ESP projects. I’ll put those slides online at the ESP website (http://esp.alcf.anl.gov) tonight or tomorrow morning.

Update on Workshop and Early Access System

Because of difficulties surrounding scheduling, nondisclosure information management, and participation by IBM, we have decided not to hold the next Early Science Program workshop this summer. Instead, we will look toward scheduling a workshop later this year, or in 2012.

Currently, we are finalizing plans for the early access system and we expect we will schedule a telecon with the Early Science teams this summer. Given the timing, it might be useful to target a workshop once the teams have some results.

Scheduling the next Early Science workshop

The ALCF would like to host a second workshop for the Early Science program participants. The format this time should be a more detailed presentation and exchange of information—a focused presentation or two on topics like hybrid MPI/OpenMP programming, and presentation of performance studies and project experiences to date (based on Blue Gene/P efforts and early Q hardware tests). I’m looking for feedback now about scheduling from project investigators and participants. Would early-to-mid June work with your schedules? Please feel free to post comments here, or email directly to [email protected] . This will likely be repeated soon in an email to the PIs and co-PIs.
