Augment the Kraken! Increasing the scientific capability and capacity of the NSF's most powerful supercomputer

1041709名获奖者此次授予Kraken 12个机柜计算节点，以及额外的144Tf和18 TB内存，使其达到1,174 Tf和147 TB。这将通过添加1,152个节点将其节点数从8,256增加到9,408。随着1,152个节点的增加，Kraken将有相当大的空间来同时运行其他作业和8,192个节点作业。实际上，可以同时运行8,192个作业和1,024个节点作业。考虑到？双式联运？分配用户作业，大多数作业大小在8,192及以上，或在1,024及以下，这将极大地提高机器对用户的响应速度。Kraken的升级将允许用户扩展他们的代码，将它们扩展到最大的NSF超级计算机，拥有超过11万个内核，实现在这次升级之前无法运行的新型号。已经有许多用户将他们的应用程序扩展到当前Kraken的全部大小，其中一些用户已经准备使用更大的系统。此外，这将有助于对已经选择在Track 1 Blue Waters系统上运行的应用程序进行扩展，并使它们为这台超大型计算机做好准备。

1041709 AndrewsThis award 12 cabinets of compute nodes, with an additional 144 TF and 18 TB of memory, to Kraken, taking it to 1,174 TF and 147 TB. This will increase its node count from 8,256 to 9,408 by adding 1,152 nodes. With the addition of 1,152 nodes, Kraken will have significant room left to run other jobs simultaneously with 8,192 node jobs. Indeed, it will be possible to run a 8,192 job and a 1,024 node job at the same time. Given the ?bi-modal? distribution of the user jobs, with most job sizes at either 8,192 and above, or at 1,024 and below, this will greatly improve the responsiveness of the machine for users. The Kraken upgrade will allow users to extend their codes by scaling them up to the largest NSF supercomputer, with over 110,000 cores, implementing new models that could not have been run before this upgrade. There already a number of users scaling their applications to the full size of the current Kraken, and some of them are already prepared to use a larger system. Additionally, this will help facilitate scaling for applications already chosen to run on the Track 1 Blue Waters system, and prepare them for that very large machine.
