Specifications

Last Updated: May 21, 2021

This topic describes the recommended specifications and scenarios of E-HPC.

E-HPC supports all specifications of ECS instances. To maximize the performance of E-HPC clusters, we recommend that you select one of the following specifications based on your scenarios. For more information about the specifications of ECS instances, see Instance families and Best practices for instance type selection.

ECS bare metal instances and Super Computing Cluster (SCC) instances

The following instances have no performance loss in virtualization and can be isolated by VPCs. You can have direct access to hardware resources. SCC instances provide a low-latency network that is based on Remote Direct Memory Access (RDMA). The network meets the parallel computing requirements of E-HPC clusters.
