创建GPU实例
更新时间：2025-02-26
本文介绍如何创建并使用BCI GPU实例。
BCI GPU规格说明
BCI提供以下型号 GPU Pod 规格，不同的 GPU 卡型号和大小会对应不同的 CPU、内存选项，请在创建工作负载时根据您的实际需求选择最合适规格，并进行资源分配。
| BCI 规格名称 | CPU | 内存 | GPU类型 | 显存 | GPU卡数 |
| bci.gna2.c8m36.1a10 | 8 | 36 | Nvidia A10 PCIE | 24*1 | 1 |
| bci.gna2.c18m74.1a10 | 18 | 74 | Nvidia A10 PCIE | 24*1 | 1 |
| bci.gna2.c30m118.2a10 | 30 | 118 | Nvidia A10 PCIE | 24*2 | 2 |
| bci.gna2.c62m240.4a10 | 62 | 240 | Nvidia A10 PCIE | 24*4 | 4 |
创建实例
配置说明如下
- 指定GPU型号，需要在 Annotation 指定 GPU型号，请注意， Annotation需要配置在Pod Spec中，而不是Deployment Spec中。
