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.

东北部的下一代协作技术：UMassUnity机器（CONTINUUM）扩展了现有的计算资源，UMassAmherst的UNITY集群，拥有八台支持尖端IBM POWER、GPGPU和FPGA架构的新型服务器。该扩展使马萨诸塞大学阿默斯特分校和达特茅斯校区以及罗得岛大学在许多重要科学领域的关键计算工作成为可能，包括引力波科学，宏基因组学，地震探测，癌症建模等。根据科学要求，现有的Unity集群扩展了8个Power9节点，每个节点都有双2.7 GHz 16核处理器，256 GB内存，由双Nvidia Tesla V100 GPGPU和Xilinx Alveo U50 FPGA加速。除了最初提出的科学驱动程序外，新服务器还支持三个校区的更多协作研究团队。此外，CONTINUUM还可以为整个开放科学网格（OSG）社区提供科学开发，并可以使用20%的计算时间。新服务器还可以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还支持EPSCoR州（RI）和马萨诸塞州的大学校园的研究和教育，其中38%的学生是有色人种。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日会议，并与东北和CAREERS Cyberteams社区合作。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
