Amazon EC2 P4 Instances

High performance for ML training and HPC applications in the cloud

Amazon Elastic Compute Cloud (Amazon EC2) P4d instances deliver high performance for machine learning (ML) training and high performance computing (HPC) applications in the cloud. P4d instances are powered by NVIDIA A100 Tensor Core GPUs and deliver industry-leading high throughput and low-latency networking. These instances support 400 Gbps instance networking. P4d instances provide up to 60% lower cost to train ML models, including an average of 2.5x better performance for deep learning models compared to previous-generation P3 and P3dn instances.

P4d instances are deployed in hyperscale clusters called Amazon EC2 UltraClusters that comprise high performance compute, networking, and storage in the cloud. Each EC2 UltraCluster is one of the most powerful supercomputers in the world, helping you run your most complex multinode ML training and distributed HPC workloads. You can easily scale from a few to thousands of NVIDIA A100 GPUs in the EC2 UltraClusters based on your ML or HPC project needs.

Researchers, data scientists, and developers can use P4d instances to train ML models for use cases such as natural language processing, object detection and classification, and recommendation engines. They can also use it to run HPC applications like pharmaceutical discovery, seismic analysis, and financial modeling. Unlike on-premises systems, you can access virtually unlimited compute and storage capacity, scale your infrastructure based on business needs, and spin up a multinode ML training job or a tightly coupled distributed HPC application in minutes, without any setup or maintenance costs.

Reduce ML training time from days to minutes

With the latest-generation NVIDIA A100 Tensor Core GPUs, each P4d instance delivers on average 2.5x better DL performance compared to previous-generation P3 instances. EC2 UltraClusters of P4d instances help everyday developers, data scientists, and researchers run their most complex ML and HPC workloads by giving access to supercomputing-class performance without any upfront costs or long-term commitments. The reduced training time with P4d instances boosts productivity, helping developers focus on their core mission of building ML intelligence into business applications.

Run the most complex multinode ML training with high efficiency

Developers can seamlessly scale to up to thousands of GPUs with EC2 UltraClusters of P4d instances. High-throughput, low-latency networking with support for 400 Gbps instance networking, Elastic Fabric Adapter (EFA), and GPUDirect RDMA technology help rapidly train ML models using scale-out/distributed techniques. EFA uses the NVIDIA Collective Communications Library (NCCL) to scale to thousands of GPUs, and GPUDirect RDMA technology enables low-latency GPU-to-GPU communication between P4d instances.

Lower the infrastructure costs for ML training and HPC

P4d instances deliver up to 60% lower cost to train ML models compared to P3 instances. Additionally, P4d instances are available for purchase as Spot Instances. Spot Instances take advantage of unused EC2 instance capacity and can lower your EC2 costs significantly with up to a 90% discount from On-Demand prices. With the lower cost of ML training with P4d instances, budgets can be reallocated to build more ML intelligence into business applications.

Easily get started and scale with AWS services

AWS Deep Learning AMIs (DLAMIs) and Amazon Deep Learning Containers make it easier to deploy P4d DL environments in minutes as they contain the required DL framework libraries and tools. You can also more easily add your own libraries and tools to these images. P4d instances support popular ML frameworks, such as TensorFlow, PyTorch, and MXNet. Additionally, P4d instances are supported by major AWS services for ML, management, and orchestration, such as Amazon SageMaker, Amazon Elastic Kubernetes Service (Amazon EKS), Amazon Elastic Container Service (Amazon ECS), AWS Batch, and AWS ParallelCluster.


Powered by NVIDIA A100 Tensor Core GPUs

NVIDIA A100 Tensor Core GPUs deliver unprecedented acceleration at scale for ML and HPC. NVIDIA A100’s third-generation Tensor Cores accelerate every precision workload, speeding time to insight and time to market. Each A100 GPU offers over 2.5x the compute performance compared to the previous-generation V100 GPU and comes with 40 GB HBM2 (in P4d instances) or 80 GB HBM2e (in P4de instances) of high-performance GPU memory. Higher GPU memory particularly benefits those workloads training on large datasets of high-resolution data. NVIDIA A100 GPUs use NVSwitch GPU interconnect throughput so each GPU can communicate with every other GPU in the same instance at the same 600 GB/s bidirectional throughput and with single-hop latency.

High-performance networking

P4d instances provide 400 Gbps networking to help customers better scale out their distributed workloads such as multinode training more efficiently with high-throughput networking between P4d instances as well as between a P4d instance and storage services such as Amazon Simple Storage Service (Amazon S3) and FSx for Lustre. EFA is a custom network interface designed by AWS to help scale ML and HPC applications to thousands of GPUs. To further reduce latency, EFA is coupled with NVIDIA GPUDirect RDMA to enable low-latency GPU-to-GPU communication between servers with OS bypass.

High-throughput, low-latency storage

Access petabyte-scale high-throughput, low-latency storage with FSx for Lustre or virtually unlimited cost-effective storage with Amazon S3 at 400 Gbps speeds. For workloads that need fast access to large datasets, each P4d instance also includes 8 TB NVMe-based SSD storage with 16 GB/sec read throughput.

Built on the AWS Nitro System

The P4d instances are built on the AWS Nitro System, which is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software to deliver high performance, high availability, and high security while also reducing virtualization overhead.
