使用 GPU 工作负载 AMI

要在您的 AWS Batch 计算资源上运行 GPU 工作负载，必须使用具有 GPU 支持的 AMI。有关更多信息，请参阅 Amazon Elastic Container Service Developer Guide 中的在 Amazon ECS 上使用 GPU 和经过 Amazon ECS 优化的 AMI。

在托管计算环境中，如果计算环境指定任何 p2 或者 p3 实例类型或实例系列，则 AWS Batch 使用经过 Amazon ECS GPU 优化的 AMI。

在非托管计算环境中，建议使用经过 Amazon ECS GPU 优化的 AMI。可以使用 AWS Command Line Interface 或 AWS Systems Manager Parameter Store GetParameter、GetParameters 和 GetParametersByPath 操作来检索元数据，从而获得建议的经过 Amazon ECS GPU 优化的 AMI。

以下示例演示 GetParameter 的用法。

AWS CLIPython
AWS CLI
$ aws ssm get-parameter --name /aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended \
                        --region us-east-2 --output json

输出在 Value 参数中包含 AMI 信息。

{
    "Parameter": {
        "Name": "/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended",
        "LastModifiedDate": 1555434128.664,
        "Value": "{\"schema_version\":1,\"image_name\":\"amzn2-ami-ecs-gpu-hvm-2.0.20190402-x86_64-ebs\",\"image_id\":\"ami-083c800fe4211192f\",\"os\":\"Amazon Linux 2\",\"ecs_runtime_version\":\"Docker version 18.06.1-ce\",\"ecs_agent_version\":\"1.27.0\"}",
        "Version": 9,
        "Type": "String",
        "ARN": "arn:aws:ssm:us-east-2::parameter/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended"
    }
}
Python
from __future__ import print_function

import json
import boto3

ssm = boto3.client('ssm', 'us-east-2')

response = ssm.get_parameter(Name='/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended')
jsonVal = json.loads(response['Parameter']['Value'])
print("image_id   = " + jsonVal['image_id'])
print("image_name = " + jsonVal['image_name'])

输出仅包含 AMI ID 和 AMI 名称：

image_id   = ami-083c800fe4211192f
image_name = amzn2-ami-ecs-gpu-hvm-2.0.20190402-x86_64-ebs

以下示例演示 GetParameters 的用法。

AWS CLIPython
AWS CLI
$ aws ssm get-parameters --names  /aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_name \
                                  /aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_id \
                         --region us-east-2 --output json

输出包含每个参数的完整元数据：

{
    "InvalidParameters": [],
    "Parameters": [
        {
            "Name": "/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_id",
            "LastModifiedDate": 1555434128.749,
            "Value": "ami-083c800fe4211192f",
            "Version": 9,
            "Type": "String",
            "ARN": "arn:aws:ssm:us-east-2::parameter/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_id"
        },
        {
            "Name": "/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_name",

            "Type": "String",
            "ARN": "arn:aws:ssm:us-east-2::parameter/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_name"
        }
    ]
}
Python
from __future__ import print_function

import boto3

ssm = boto3.client('ssm', 'us-east-2')

response = ssm.get_parameters(
            Names=['/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_name',
                   '/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_id'])
for parameter in response['Parameters']:
    print(parameter['Name'] + " = " + parameter['Value'])

以下示例演示 GetParametersByPath 的用法。

AWS CLIPython
AWS CLI
$ aws ssm get-parameters-by-path --path /aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended \
                                 --region us-east-2 --output json
