NAME

Paws::Batch::ResourceRequirement

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::Batch::ResourceRequirement object:

  $service_obj->Method(Att1 => { Type => $value, ..., Value => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::Batch::ResourceRequirement object:

  $result = $service_obj->Method(...);
  $result->Att1->Type

DESCRIPTION

The type and amount of a resource to assign to a container. The supported resources include "GPU", "MEMORY", and "VCPU".

ATTRIBUTES

REQUIRED Type => Str

The type of resource to assign to a container. The supported resources include "GPU", "MEMORY", and "VCPU".

REQUIRED Value => Str

The quantity of the specified resource to reserve for the container. The values vary based on the "type" specified.

type="GPU"

The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

GPUs are not available for jobs running on Fargate resources.

type="MEMORY"

The memory hard limit (in MiB) present to the container. This parameter is supported for jobs running on EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to "Memory" in the Create a container (https://docs.docker.com/engine/api/v1.23/#create-a-container) section of the Docker Remote API (https://docs.docker.com/engine/api/v1.23/) and the "--memory" option to docker run (https://docs.docker.com/engine/reference/run/). You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to "Memory" in the Create a container (https://docs.docker.com/engine/api/v1.23/#create-a-container) section of the Docker Remote API (https://docs.docker.com/engine/api/v1.23/) and the "--memory" option to docker run (https://docs.docker.com/engine/reference/run/).

If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management (https://docs.aws.amazon.com/batch/latest/userguide/memory-management.html) in the AWS Batch User Guide.

For jobs running on Fargate resources, then "value" is the hard limit (in MiB), and must match one of the supported values and the "VCPU" values must be one of the values supported for that memory value.

value = 512: "VCPU" = 0.25
value = 1024: "VCPU" = 0.25 or 0.5
value = 2048: "VCPU" = 0.25, 0.5, or 1
value = 3072: "VCPU" = 0.5, or 1
value = 4096: "VCPU" = 0.5, 1, or 2
value = 5120, 6144, or 7168: "VCPU" = 1 or 2
value = 8192: "VCPU" = 1, 2, or 4
value = 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384: "VCPU" = 2 or 4
value = 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720: "VCPU" = 4

type="VCPU": The number of vCPUs reserved for the container. This parameter maps to "CpuShares" in the Create a container (https://docs.docker.com/engine/api/v1.23/#create-a-container) section of the Docker Remote API (https://docs.docker.com/engine/api/v1.23/) and the "--cpu-shares" option to docker run (https://docs.docker.com/engine/reference/run/). Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.
For jobs running on Fargate resources, then "value" must match one of the supported values and the "MEMORY" values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

value = 0.25: "MEMORY" = 512, 1024, or 2048
value = 0.5: "MEMORY" = 1024, 2048, 3072, or 4096
value = 1: "MEMORY" = 2048, 3072, 4096, 5120, 6144, 7168, or 8192
value = 2: "MEMORY" = 4096, 5120, 6144, 7168, 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384
value = 4: "MEMORY" = 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, 16384, 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720
