SUMMARY:Chronicles of Astra: Challenges and Lessons from the First Petasca
 le Arm Supercomputer
DESCRIPTION:Paper\n\nChronicles of Astra: Challenges and Lessons from the 
 First Petascale Arm Supercomputer\n\nPedretti, Younge, Hammond, Laros III,
  Curry...\n\nArm processors have been explored in HPC for several years, h
 owever there has not yet been a demonstration of viability for supporting 
 large-scale production workloads. In this paper, we offer a retrospective 
 on the process of bringing up Astra, the first petascale supercomputer bas
 ed on 64-bit Arm processors, and validating its ability to run production 
 HPC applications. Through this process several immature technology gaps we
 re addressed, including software stack enablement, Linux bugs at scale, th
 ermal management issues, power management capabilities and advanced contai
 ner support. From this experience, several lessons learned that contribute
 d to the successful deployment of Astra are formulated. These insights can
  be helpful to accelerate deploying and maturing other first-seen HPC tech
 nologies. With Astra now supporting many users running a diverse set of pr
 oduction applications at multi-thousand node scales, we believe this const
 itutes strong supporting evidence that Arm is a viable technology for even
  the largest-scale supercomputer deployments.\n\nTag: Architectures, Quant
