使用 GPU 工作负载

要在您的 Amazon 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 。在 Amazon ECS 上使用 GPU和Amazon ECS 优化型 AMI在Amazon Elastic Container Service 开发指南.

在托管计算环境中，如果计算环境指定p2、p3、p4、g3、g3s、g4，或者g5然后，实例类型或实例系列Amazon Batch使用亚马逊 ECS GPU 优化的 AMI。

在非托管计算环境中，建议使用经 Amazon ECS GPU 优化的 AMI。您可以使用Amazon Command Line Interface要么Amazon Systems ManagerParameter StoreGetParameter、GetParameters, 和GetParametersByPath操作来检索元数据，从而获得建议的经 Amazon ECS GPU 优化型 AMI。

以下示例演示 GetParameter 的用法。

Amazon 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。

Amazon 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",
            "LastModifiedDate": 1555434128.712,

            "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')

            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'])

/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_id = ami-083c800fe4211192f
/aws/service/ecs/optimized-ami/amazon-linux-2/gpu/recommended/image_name = amzn2-ami-ecs-gpu-hvm-2.0.20190402-x86_64-ebs

以下示例演示 GetParametersByPath 的用法。

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