HPC CPU

Compared with existing CPU-type instances, HPC CPU instances are configured with a vRDMA network, which significantly enhances network performance and improves speedup for large-scale clusters. This instance type is applicable for industrial simulation, EDA simulation, and other HPC scenarios.

For information about instance types, estimated instance fees, instance type changes, and instance naming rules, please refer to Instance types and specifications.

HPC CPU ebmhpcg3ad

tip

This instance is currently in Beta in the China (Beijing) and China (Shanghai) regions. If you need a trial, please contact your account manager to apply.

You can create an instance of this type by using any of the following images:

Rocky Linux 8.4 with ofed 24.10

Rocky Linux 8.8 with ofed 24.10

Features

Type	Performance
Computing	The 4th-generation AMD processor with a processor base frequency of 2.6 GHz and an all-core turbo frequency of 3.7 GHz. The processor-to-memory ratio is 1:8. A bare metal type, supporting 192 physical cores and 1536 GiB of memory. Hyper-threading can be enabled.
Storage	You can use ESSD volumes or TSSD volumes. A maximum of 16 volumes (including 1 system volume) can be mounted. High-performance (high IOPS, high throughput, low latency) local SSDs are configured.
Network	Maximum network bandwidth: 164 Gbit/s. Maximum PPS: 4,000,000. 164 Gbit/s vRDMA network bandwidth between nodes is provided. The vRDMA feature is currently in Beta. If you need a trial, please contact your account manager to apply.

Applicable scenarios

Applicable for industrial simulation, EDA simulation, geological exploration, weather forecasting, molecular dynamics simulation, and other HPC scenarios.

Instance types and metrics

tip

The maximum throughput (PPS) varies significantly in different business scenarios. Therefore, we recommend that you conduct a business stress test to learn the instance performance. After that, you can select an appropriate instance type.
