CC* Compute: GPU Infrastructure to Explore New Algorithmic & AI Methods in Data-Driven Science and Engineering at Tufts University

塔夫茨大学的高级科学和工程研究正在使用越来越复杂的模型，算法，模拟和机器学习方法来处理大型数据集。数据集越大或模型越复杂，计算所需的时间就越长，这会减缓研究人员的进展并限制他们的创新能力。Tufts在其高性能计算集群中增加了六个图形处理单元（GPU）增强型计算节点，加速了算法并行化加速和机器学习深度学习领域的科学和工程研究。生物学、化学、计算机科学、数学、物理学和城市规划领域的研究人员利用GPU增强的基础设施来开发新的算法和模型，并加速科学发现。通过与国家科学基金会资助的T-TRIPODS合作，（数据科学原理的跨学科研究）项目和塔夫茨大学STEM多样性中心的基础设施，为代表性不足的学生提供了新的机会，以获得和扩展数据科学和高性能计算技能。六个GPU增强的计算节点每个都配置有双20核英特尔至强金牌6248 CPU，768 GB RAM和8个NVIDIA Tesla V100（32 GB）GPU与NVLink互连，以提高多GPU计算的扩展性。这些节点与100千兆网络相连，塔夫茨大学的研究人员可以通过开放科学网格（OSG）外部访问。 大核心数、大RAM、互连GPU架构为研究人员在复杂计算分析中混合使用传统和GPU增强方法提供了最大的灵活性。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响评审标准进行评估，被认为值得支持。

Advanced scientific and engineering research at Tufts University is employing increasingly complex models, algorithms, simulations and machine learning approaches to large datasets. The larger the dataset or the more complex the model, the longer it takes to compute, slowing down researchers' progress and limiting their ability to innovate. Tufts' addition of six Graphics Processing Unit (GPU) enhanced compute nodes to its high-performance computing cluster accelerates scientific and engineering research in the areas of Algorithm Parallelization & Acceleration and Machine Learning & Deep Learning. Researchers in biology, chemistry, computer science, mathematics, physics, and urban planning leverage the GPU enhanced infrastructure to develop new algorithms and models and accelerate scientific discoveries. Through collaboration with the NSF-funded T-TRIPODS (Transdisciplinary Research in Principles of Data Science) project and the Center for STEM diversity at Tufts, the infrastructure provides new opportunities for underrepresented students to acquire and extend data science and high-performance computing skills.The six GPU enhanced compute nodes are each configured with dual 20-core Intel Xeon Gold 6248 CPUs, 768GB of RAM and 8 NVIDIA Tesla V100 (32GB) GPUs interconnected with NVLink to improve scaling of multi-GPU computation. The nodes are linked with a 100 gigabit network and are accessible to researchers at Tufts and externally through the Open Science Grid (OSG). The large core count, large RAM, interlinked GPU architecture provides the greatest flexibility for researchers to mix traditional and GPU-enhanced approaches in complex computational analysis.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
