论文摘要
HPC作为服务（HPCAA）是通过云服务公开HPC资源的新方法。但是，继续努力将大规模耦合的应用程序与高度交通通信的高度耦合应用程序同步（如本地超级计算机中）同步，并远离由于网络潜伏期而令人满意。结果，在上述情况下，建议将HPCAA与一个或几个实例一起使用。在本文中，我们认为与RAM相比，与RAM相比，新的内存硬件，即非挥发性RAM（NVRAM），可以使此类计算扩展到具有边缘化惩罚的数量级。此外，我们建议将NVRAM引入HPCAA可以以多种形式对用户和供应商具有成本效益。
HPC as a service (HPCaaS) is a new way to expose HPC resources via cloud services. However, continued effort to port large-scale tightly coupled applications with high interprocessor communication to multiple (and many) nodes synchronously, as in on-premise supercomputers, is still far from satisfactory due to network latencies. As a consequence, in said cases, HPCaaS is recommended to be used with one or few instances. In this paper we take the claim that new piece of memory hardware, namely Non-Volatile RAM (NVRAM), can allow such computations to scale up to an order of magnitude with marginalized penalty in comparison to RAM. Moreover, we suggest that the introduction of NVRAM to HPCaaS can be cost-effective to the users and the suppliers in numerous forms.
