Contoh definisi tugas Neuron

Contoh alokasi perangkat terkelola

Contoh berikut menunjukkan definisi tugas yang meminta semua perangkat Neuron pada instance menggunakan resourceRequirements parameter. Pendekatan ini hanya tersedia pada Instans Terkelola.

{
    "family": "ecs-neuron",
    "requiresCompatibilities": ["MANAGED_INSTANCES"],
    "networkMode": "awsvpc",
    "cpu": "8192",
    "memory": "16384",
    "executionRoleArn": "${YOUR_EXECUTION_ROLE}",
    "containerDefinitions": [
        {
            "name": "neuron-inference",

            "essential": true,
            "command": [
                "--model", "${YOUR_HUGGING_FACE_MODEL_ID}",
                "--port", "8080",
                "--tensor-parallel-size", "2",
                "--allow-non-cached-model"
            ],
            "portMappings": [
                {
                    "containerPort": 8080,
                    "protocol": "tcp"
                }
            ],
            "resourceRequirements": [
                {
                    "type": "NeuronDevice",
                    "value": "ALL"
                }
            ]
        }
    ]
}

Dalam contoh ini, gambar kontainer menyertakan server inferensi VllM yang dioptimalkan untuk Neuron. AWS Titik masuk gambar mengunduh model dari HuggingFace, mengompilasinya untuk Neuron, dan memulai server OpenAI-compatible API pada port 8080. Ganti ${YOUR_HUGGING_FACE_MODEL_ID} dengan ID HuggingFace model Anda.

Contoh spesifikasi perangkat manual

Contoh berikut menunjukkan definisi tugas Linux untuk inf1.xlarge menggunakan tipe peluncuran EC2 dengan linuxParameters.devices untuk menentukan jalur perangkat Neuron.
