SCC after dark: Clustering all night long

Students join the Teraflop club


SC10 Last week the fourth annual Student Cluster Competition was held at SC10 in New Orleans. Teams from eight universities brought their own self-designed and built clusters to the show, re-assembled them, and raced to complete a set of benchmarks and workloads in the quickest time. The Register's resident HPC analyst Dan Olds was our reporter at the scene.

One of the most interesting aspects of the Student Cluster Competition is the way it stresses the humans even more than the hardware. The students have 46 hours to run as many of the benchmarks as possible, so they man their equipment around the clock to maximize throughput.

My videos to accompany this article were taken early Wednesday morning, about 15 hours before their final results were due. This was the second and last night of the competition. Team moods were mostly quiet and subdued. The fatigue was showing on everyone, including me, as I asked the same questions over and over again. Despite my barely coherent interview technique, we learn more about the teams, their strategies, and the nature of the challenge.

In this first SCC video, I talk to hometown favorite LSU about how it feels to be one of three teams to break through the teraflop barrier - a first in SCC history.

We next visit the NNSU team from Russia - almost catching them on film watching a movie. They converted their booth into a mini Cineplex, complete with popcorn and semi-surround sound.

And why not? The systems were running smoothly, and the 42" LCD was just sitting there. The next team, Colorado, was all business, working away on the benchmarks. Same thing at Purdue; their quiet demeanor was even quieter than usual, at least on camera. Of course, this could have been because of the late hour.

The other teams, seen here in my second SCC video, were more expansive. Texas talked about joining the newly-established SCC Teraflop Club with their 1.07 LINPACK result and also discussed their strategy in approaching the task of cracking 4,000,000 passwords.

With FAMU, we talked with a very tired team member about their roller coaster journey at the show: how their hardware didn't show up as planned, and how they managed to finish the competition on borrowed equipment. With Stony Brook, we touched on light bedtime reading and the pros and cons of using DoD Military Grade caffeine during the competition.

Rounding out the night was a visit to the NTHU team, where I marveled at the durability of the school seal tattoo they had put on my hand a few days earlier. ®

  • A peek into Gigabyte's GPU Arm for AI, HPC shops
    High-performance platform choices are going beyond the ubiquitous x86 standard

    Arm-based servers continue to gain momentum with Gigabyte Technology introducing a system based on Ampere's Altra processors paired with Nvidia A100 GPUs, aimed at demanding workloads such as AI training and high-performance compute (HPC) applications.

    The G492-PD0 runs either an Ampere Altra or Altra Max processor, the latter delivering 128 64-bit cores that are compatible with the Armv8.2 architecture.

    It supports 16 DDR4 DIMM slots, which would be enough space for up to 4TB of memory if all slots were filled with 256GB memory modules. The chassis also has space for no fewer than eight Nvidia A100 GPUs, which would make for a costly but very powerful system for those workloads that benefit from GPU acceleration.

  • GitLab version 15 goes big on visibility and observability
    GitOps fans can take a spin on the free tier for pull-based deployment

    One-stop DevOps shop GitLab has announced version 15 of its platform, hot on the heels of pull-based GitOps turning up on the platform's free tier.

    Version 15.0 marks the arrival of GitLab's next major iteration and attention this time around has turned to visibility and observability – hardly surprising considering the acquisition of OpsTrace as 2021 drew to a close, as well as workflow automation, security and compliance.

    GitLab puts out monthly releases –  hitting 15.1 on June 22 –  and we spoke to the company's senior director of Product, Kenny Johnston, at the recent Kubecon EU event, about what will be added to version 15 as time goes by. During a chat with the company's senior director of Product, Kenny Johnston, at the recent Kubecon EU event, The Register was told that this was more where dollars were being invested into the product.

  • To multicloud, or not: Former PayPal head of engineering weighs in
    Not everyone needs it, but those who do need to consider 3 things, says Asim Razzaq

    The push is on to get every enterprise thinking they're missing out on the next big thing if they don't adopt a multicloud strategy.

    That shove in the multicloud direction appears to be working. More than 75 percent of businesses are now using multiple cloud providers, according to Gartner. That includes some big companies, like Boeing, which recently chose to spread its bets across AWS, Google Cloud and Azure as it continues to eliminate old legacy systems. 

    There are plenty of reasons to choose to go with multiple cloud providers, but Asim Razzaq, CEO and founder at cloud cost management company Yotascale, told The Register that choosing whether or not to invest in a multicloud architecture all comes down to three things: How many different compute needs a business has, budget, and the need for redundancy.
