A Quantitative Approach for Adopting Disaggregated Memory in HPC Systems
Jacob Wahlgren, Gabin Schieffer, Maya Gokhale +1
Memory disaggregation has recently been adopted in data centers to improve resource utilization, motivated by cost and sustainability. Recent studies on large-scale HPC facilities…
Evaluating Emerging CXL-enabled Memory Pooling for HPC Systems
Jacob Wahlgren, Maya Gokhale, Ivy B. Peng
Current HPC systems provide memory resources that are statically configured and tightly coupled with compute nodes. However, workloads on HPC systems are evolving. Diverse workload…
Benchmarking Test-Time Unsupervised Deep Neural Network Adaptation on Edge Devices
Kshitij Bhardwaj, James Diffenderfer, Bhavya Kailkhura +1
The prediction accuracy of the deep neural networks (DNNs) after deployment at the edge can suffer with time due to shifts in the distribution of the new data. To improve robustnes…
Combining Emulation and Simulation to Evaluate a Near Memory Key/Value Lookup Accelerator
Joshua Landgraf, Scott Lloyd, Maya Gokhale
Processing large numbers of key/value lookups is an integral part of modern server databases and other "Big Data" applications. Prior work has shown that hash table based key/value…
Semi-supervised on-device neural network adaptation for remote and portable laser-induced breakdown spectroscopy
Kshitij Bhardwaj, Maya Gokhale
Laser-induced breakdown spectroscopy (LIBS) is a popular, fast elemental analysis technique used to determine the chemical composition of target samples, such as in industrial anal…
Demystifying the Performance of HPC Scientific Applications on NVM-based Memory Systems
Ivy Peng, Kai Wu, Jie Ren +2
The emergence of high-density byte-addressable non-volatile memory (NVM) is promising to accelerate data- and compute-intensive applications. Current NVM technologies have lower pe…
UMap: Enabling Application-driven Optimizations for Page Management
Ivy B. Peng, Marty McFadden, Eric Green +5
Leadership supercomputers feature a diversity of storage, from node-local persistent memory and NVMe SSDs to network-interconnected flash memory and HDD. Memory mapping files on di…
System Evaluation of the Intel Optane Byte-addressable NVM
Ivy B. Peng, Maya B. Gokhale, Eric W. Green
Byte-addressable non-volatile memory (NVM) features high density, DRAM comparable performance, and persistence. These characteristics position NVM as a promising new tier in the me…
Interfacing Interpreted and Compiled Languages to Support Applications on a Massively Parallel Network of Workstations (MP-NOW)
Jeremy Kepner, Maya Gokhale, Ron Minnich +2
Astronomers are increasingly using Massively Parallel Network of Workstations (MP-NOW) to address their most challenging computing problems. Fully exploiting these systems is made…
