Hello, is this thing on? We back on-line after a 2 year hiatus! Well, not because I did not want to post here, but I could not find the time to post the insightful content you expect from a free web site. Also, we don't use AI, never will for that matter. So someone actually has to type on a keyboard.

In any case, please go to the bash web page (we d work very hard on these things) and have a look at this years theme, complete with snarky content and foot notes.

The SC25 Bash is at the standard time after the opening Gala, 9pm on Monday Nov. 17. See the web page for directions and more information.

The Beowulf Bash began in the late nineties when a bunch of Beowulf cluster geeks gathered for beer and pretzels during Supercomputing. Over the years, the success of the Beowulf Bash brand continued to grow at a steady rate, and the event is now an established and recognizable part of the annual SC experience.

Which makes it the perfect time to rebrand as the Y Event.

Of course, many of you may ask: why Y? Well, it seems that other letters were taken.

And then there is the church thing?

In any case, if attending SC23, just show up Monday night November 13 after the Gala. Services through 9pm to Midnight. Location: 1160 Lincoln Street, Denver

The SC23 Beowulf Bash was wildly successful, or was it wild and successful? You can judge for yourself because we have video evidence.

Thank you, Kiwi, for the video.

It should be noted that even though the video shows a fun main venue, by tradition, the Beowulf Bash always has rooms and locations where attendees can engage in conversation.

All this HPC fun was made possible by the Beowulf Bash Angels and Demons team and our wonderful supporting vendors. (That is not Ted Danson on the left.) One key demon did not make it for the team picture, but he is easily identified in the video.

Note: this paper was prepared for a conference that we decided not to attend (Okay, it was not accepted). It is written in a more formal style than the normal ClusterMonkey articles and is sponsored by the The Beowulf Foundation

Abstract

Popular homogeneous clustered HPC systems (e.g., commodity x86 servers connected by a high-speed interconnect) have given way to heterogeneous clusters comprised of multi-core servers, high speed interconnects, accelerators (often GPU based), and custom storage arrays. Cluster designers are often faced with finding a balance between purpose-built (tailored to specific problem domains ) and general use systems. Traditional cluster-based approaches, however, all share a hard boundary between internal server buses (mainly PCIe) and the rest of the cluster. In heterogeneous environments, the server boundary often creates inefficient resource management, limits solution flexibility, and heavily influences the design of clustered HPC applications. This paper explores the malleability of the GigaIO™ FabreX™ PCIe memory fabric in relation to HPC cluster applications. A discussion of emerging concepts (e.g., a routable PCIe bus) and hands-on benchmarks using shared GPUs will be provided. In addition, results of a simple integration with SLURM resource scheduler will be discussed as way to make composable/malleable computing transparently available to end-users. Keywords.
