Choose Supported EC2 Instance Machine Types

On the Create Cluster page, under Machine Configuration, select a Worker Machine Type from the list. You can also edit the instance type on existing clusters. Amazon EC2 provides instance types with various combinations of CPU, GPU, memory, network performance, and storage. Choose an instance that suits your application.


For deep learning, choose an instance with GPUs such as the P2, P3, or G3 instances. The different machine types provide a range of performance at different prices. For example, P2s have K80 GPUs and P3s have V100 GPUs, both with high performance for general computation including deep learning. G3s have M60 GPUs with high single-precision performance well suited for deep learning, image processing and computer vision.

Cloud Center supports the following instance types:

For more details on newly added compute optimized instances and regional availability, see the Amazon Web Services web site: Amazon EC2 Instance Types. Note that Amazon Web Services describes instances in terms of vCPUs, where v means virtual core (or logical core). Usually, each physical core has two virtual cores. For example, a c4.8xlarge has 18 physical CPU cores, which corresponds to 36 vCPUs.


  • Cloud Center only supports Linux On-demand instances.

  • c4.8xlarge is the suggested default instance.

  • Not all instances are available in all regions.

  • Cloud Center currently supports the following regions:

    • US East (N.Virginia)

    • EU West (Ireland)

    • AP Northeast (Tokyo)

  • Cloud Center supports reserved instances in addition to On-demand. Cloud Center does not support dedicated or spot instances.

  • Cloud Center supports at most one worker per physical core. Although Amazon Web Services machines can have many virtual cores, Cloud Center restricts use to at most one worker per physical core for optimal performance. Each physical core has two virtual cores with a shared Floating Point Unit. Most MATLAB computations use this unit because they are double-precision floating point. Restricting to one worker per physical core ensures that each worker has exclusive access to a Floating Point Unit and optimizes performance.

To use reserved instances with Cloud Center, you need to purchase reserved instances with the following Cloud Center supported attributes:

  • Instance type: one of the machine types supported by Cloud Center, listed in the table in this section: Choose Supported EC2 Instance Machine Types.

  • Platform description: Linux.

  • Tenancy: default.

  • Region: one of regions supported by Cloud Center (US East (N.Virginia), EU West (Ireland), AP Northeast (Tokyo)).

  • Availability Zone: Availability Zone within the selected region, must match the Availability Zone of the subnet selected.

AWS Resource Limits

The maximum number of instances that you can start in Cloud Center depends on your AWS On-demand instance limits. On-demand instance limits determine the maximum number of virtual central processing units (vCPUs) that you can use. In most cases, a physical core corresponds to 2 vCPUs. For example, a c4.8xlarge instance has 18 physical CPU cores, which corresponds to 36 vCPUs. To determine how many vCPUs you need, use the vCPU limits calculator, which you can find in your AWS EC2 console by selecting Limits>Calculate vCPU limit. For more information on On-demand instance limits, see On-Demand Instances.

For more information on AWS EC2 limits for any type of resource, see Amazon EC2 Service Quotas.
