Devon Bautista

Devon-Bautista.jpeg

Devon Bautista is a returning post-baccalaureate researcher at USRC/vHPC-DES who first arrived in 2019. His current project focuses on open source firmware in HPC cluster nodes and decreasing provisioning latency by moving much of the provisioning process from the operating system into the firmware. He graduated from Arizona State University in 2019 with a BS in Computer Systems Engineering and is currently pursuing an MS in Computer Engineering, also at ASU. He also has broad research interests, but is partial to anything systems-related such as the interaction between software and hardware. In his free time he also messes around with computers, makes/plays/listens to music, water skis, and enjoys camping.

Ezra Brooker is a Computational Science PhD Candidate at Florida State University with the Department of Scientific Computing He previously attended Florida State University, earning a Bachelor's of Science in Physics and Astrophysics (2015). Ezra has also participated in previous LANL summer student programs outside of the USRC (2018,2019). His research interests include the detonability of white dwarf plasma in the Type Ia explosions, the core-collapse supernovae explosion engine, cosmic dust formation in the outflows of core-collapse supernovae, the influence of magnetic fields in astrophysical problems, and code development for scientific applications. His personal interests, to name a few, are reading, hiking, playing his bass guitar, and cooking. He is also a proud cat and dog owner. At the USRC, Ezra works on scaling up current dust formation models, developed over previous visits to LANL, porting the dust formation code to GPU use, and moving 1-D CCSNe hydro models into 2- and 3-D models to evolve the outflow for more physically realistic data for dust calculations..

Dakota Fulp is currently a MS student at Clemson University in the Holcombe Department of Computer Engineering. He completed his Bachelor’s degree in both Computer Science and Applied Physics in 2015 and 2013 respectively. In 2015, he worked remotely as a post-bachelor student researcher with NMC while working on a variety of different projects including development and improvements to the DECAF-FSEFI fault injection platform, enhancement of HPC log analysis through identifying message origin in source code, as well as improvements to the SaNSA platform. Dakota’s primary fields of research include lossy compression, fault tolerance, and data visualization. Specifically, his work focuses on understanding and improving the resiliency of lossy compressed data to soft errors as well as utilization of lossy compression for in-line data reduction.

Onkar Patil

Devon-Bautista.jpeg

Onkar is a PhD student at North Carolina State University in the Department of Computer Science since 2016. He completed his Master's thesis program in Computer Science from the same university in 2014. After that he worked full-time for NetApp Inc. as Product Support Engineer for two years. He has also worked at Hewlett Packard Labs, Palo Alto and Oak Ridge National Laboratories, Oak RIdge as an intern. Onkar's current research field is primarily based on Compilers and Heterogeneous Memory architectures. His current work is focused on using static code analysis for automating memory placements in complex memory systems. He has previously worked with power consumption control for HPC systems, Predictable collective communication for on-chip mesh networks and Transactional HPC: a framework for stencil application in memory centric architectures.

During his time at NMC, Onkar focuses on memory allocation and placement for DRAM-NVM memory systems.

Eli Snyder

Braeden-Slade.jpeg

(Richard) "Eli" Snyder graduated from Missouri University of Science and Technology with a Computer Engineering bachelor's of science in 2018. He began his Post-Bac that summer, working under Paul Peltz on the Next Generation Software Stack project. He began by writing and modifying Ansible playbooks to prepare for future migration from Warewulf to Ansible on production systems. He then moved on to attempting to create a central repository of RPMs using Open Build Service (OBS) as the core software, but was unable to successfully install it after several months of attempts. He is currently analyzing Slurm data and system logs to determine the reason for the multitude of memory errors that occurred on Trinitite during 2018. In the near future he will be returning to school to study Psychology in preparation for becoming a mental health therapist.
