When is water cooling not wet?

There is new white paper out entitled Energy Performance Evaluation of Aquila’s Aquarius Fixed Cold Plate Cooling System at NREL’s High Performance Computing Center. Before you assume this is YAWCC (Yet Another Water Cooled Cluster) you may want to consider that no water or liquids ever "touch" any processors. How then does it work? you may ask. Basically Aquila has a clever design that separates the water/processor interface with a highly efficient transfer medium. This design keeps the water contained in cooling circuit while the servers are free to be "dry servers" and require no internal plumbing. Bottom line: highly efficient water cooling with no plumbing or leaks. The Executive Summary (reprinted with permission) provides more details.

Julia Computing Awarded $910,000 Grant by Alfred P. Sloan Foundation, Including $160,000 for STEM Diversity (the following is based on a press release from Julia Computing)

Cambridge, MA – Julia Computing has been granted $910,000 by the Alfred P. Sloan Foundation to support open-source Julia development, including $160,000 to promote diversity in the Julia community.

The grant will support Julia training, adoption, usability, compilation, package development, tooling and documentation.

The diversity portion of the grant will fund a new full-time Director of Diversity Initiatives plus travel, scholarships, training sessions, workshops, hackathons and Webinars. Further information about the new Director of Diversity Initiatives position is below for interested applicants.

Julia Computing CEO Viral Shah says, “Diversity of backgrounds increases diversity of ideas. With this grant, the Sloan Foundation is setting a new standard of support for diversity which we hope will be emulated throughout STEM.”

We've all been to "those other" developer events: Sitting in a room watching a succession of never-ending slide presentations. Engagement with the audience, if any, is minimal. We leave with some tips and tools that we might be able to put into practice, but frankly, we attended because we were supposed to. The highlight was actually the opportunity to connect with industry contacts.

Key members of the OpenPOWER Foundation envisioned something completely different in their quest to create the perfect developer event, something that has never been done before: What if developers at a developer event actually spent their time developing?

from the read-this free-book-while eating-lunch department

The platform is offering a free (this week) pdf-book called The State of HPC Cloud. From their web page:

We are pleased to announce that the first book from Next Platform Press, titled “The State of HPC Cloud: 2016 Edition,” is complete. The printed book will be available on Amazon.com and other online bookstores in December, 2016. However, in the meantime, supercomputing cloud company, Nimbix, is backing an effort to offer a digital download edition for free for this entire week—from October 31, until November 6.

This resource is not a bunch of industry promotional papers slapped together to look like a book. The free pdf-book is 80 pages and has extensive references. Good stuff and worth reading. Get it before Nov 6.

From the Open MPI Team -- go team

The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 3.0.0.

v3.0.0 is the start of a new release series for Open MPI. Open MPI 3.0.0 enables MPI_THREAD_MULTIPLE by default, so a build option to Open MPI is no longer required to enable thread support. Additionally, the embedded PMIx runtime has been updated to 2.1.0 and the embedded hwloc has been updated to 1.11.7. There have been numerous other bug fix and performance improvements. Version 3.0.0 can be downloaded from the main Open MPI web site.
