II-EN: Virgo 3 -- GPU Upgrade to the UTEP Distributed Computing Lab

这个项目的重点是升级现有的计算集群，处女2，具有图形处理单元（GPU）能力。升级后的处女座-3集群将增强德克萨斯大学埃尔帕索分校（UTEP）分布式计算实验室（DCL）的计算基础设施，并增加UTEP研究人员对HPC资源的访问。处女-3将被研究人员用来开发他们计算工作负载中存在的潜在并行性。处女-3的gpu将显著提高UTEP研究人员的研究效率，这将导致在心脏可视化和通信网络等领域有更快速的发现。由于固有的数据级并行性，使用gpu可以更有效地分析心脏和人体躯干的有限元模型。这种更有效的有限元分析将加速UTEP研究人员的工作，推动心电图领域的发展。gpu还可以用于为离散事件模拟提供经济有效的加速，以提高通信网络研究的生产率，其中40%的离散事件模拟计算时间用于更新未来事件列表。本研究将探索利用gpu来加速未来事件列表的操作。此外，处女座3号将可供其他研究人员使用，这样他们就可以在他们的研究活动中利用分布式计算的好处。最后，该项目将通过针对德克萨斯州埃尔帕索地区未被充分代表的少数民族大学预科学生的暑期电脑夏令营产生广泛的影响。

This project focuses on the upgrade of an existing computing cluster, Virgo-2, with Graphics Processing Unit (GPU) capability. The upgraded cluster, Virgo-3, will enhance the computational infrastructure of the Distributed Computing Laboratory (DCL) at the University of Texas at El Paso (UTEP), as well as increasing access to HPC resources by UTEP researchers. Virgo-3 will be utilized by researchers to exploit the potential parallelism that exists in their computational workloads. The GPUs in Virgo-3 will significantly increase the research productivity of UTEP researchers, which will lead to more rapid discoveries in areas such as cardio-visualization and communication networks. A finite element model of the heart, as well as the human torso, can be analyzed more efficiently using GPUs as a result of the inherent data-level parallelism. This more efficient finite element analysis will accelerate the work of UTEP researchers to advance the field of electrocardiography. GPUs can also be used to provide cost effective speedup for discrete event simulation to improve the productivity of communication networks research, where forty percent of computation time for discrete event simulation is consumed by updates to the future event list. This research will explore the utilization of GPUs to speedup future event list manipulation. Additionally, Virgo-3 will be available to other researchers, so that they can utilize the benefits of distributed computing in their research activities.Finally, this project will have broad-based impact through summer computer camps that are targeted to underrepresented minority pre-college students in the El Paso, Texas region.
