COllaborative Next-generation Technology In the Northeast: the UMassUnity Machine (CONTINUUM) extends an existing computational resource, UMass Amherst’s UNITY cluster, with eight novel servers that support cutting-edge IBM POWER, GPGPU and FPGA architectures. This extension enables key computational efforts at UMass Amherst and Dartmouth campuses, and the University of Rhode Island in numerous important science areas, including gravitational wave science, metagenomics, earthquake detection, modeling cancer and others. Based on the science requirements, the existing Unity cluster is extended with eight Power9 nodes, each with dual 2.7 GHz 16-core processors, 256 GB memory, accelerated by dual Nvidia Tesla V100 GPGPUs and a Xilinx Alveo U50 FPGA. Beyond the initial science drivers proposed, the new servers support many more collaborative research teams on the three campuses. Furthermore, CONTINUUM enables scientific development for the entire Open Science Grid (OSG) community, with access to 20% of the compute time.The new servers also serve as an important tool for training undergraduate and graduate students in the efficient use of cutting-edge HPC systems. In addition, CONTINUUM supports research and education in an EPSCoR state (RI) and a university campus in Massachusetts with 38% students of color. To promote collaborations with researchers in the wider region, CONTINUUM personnel participate in the regional HPC Day conference and collaborate with the Northeast and CAREERS Cyberteams communities.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.

东北地区的协作下一代技术：UMassUnity Machine (CONTINUUM) 通过八个支持尖端 IBM POWER、GPGPU 和 FPGA 架构的新型服务器扩展了现有的计算资源，即 UMass Amherst 的 UNITY 集群。麻省大学阿默斯特分校和达特茅斯校区以及罗德岛大学在许多重要的科学领域，包括引力波科学、宏基因组学、地震探测、癌症建模和根据科学要求，现有的 Unity 集群扩展了 8 个 Power9 节点，每个节点配备双 2.7 GHz 16 核处理器、256 GB 内存，并由双 Nvidia Tesla V100 GPGPU 和 Xilinx Alveo U50 FPGA 加速。科学驱动者提出，新服务器支持三个校区的更多协作研究团队此外，CONTINUUM 还支持整个开放科学网格 (OSG) 的科学开发。社区，可使用 20% 的计算时间。新服务器还可作为培训本科生和研究生有效使用尖端 HPC 系统的重要工具。此外，CONTINUUM 支持 EPSCoR 州的研究和教育。 (RI) 和马萨诸塞州的一所大学校园，其中 38% 是有色人种学生。为了促进与更广泛地区的研究人员的合作，CONTINUUM 人员参加了地区 HPC Day 会议，并与 Northeast 和 CAREERS Cyber​​teams 社区合作。该奖项通过使用基金会的智力价值和更广泛的影响审查标准进行评估，NSF 的法定使命被认为值得支持。
