You can call this operation to query available HPC clusters. The request parameters are used as filters. Specified parameters have logical AND relations. The request parameters are not dependent on each other.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer automatically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes DescribeHpcClusters

The operation that you want to perform. Set the value to DescribeHpcClusters.

RegionId String Yes cn-hangzhou

The region ID of the HPC cluster. You can call the DescribeRegions operation to query the most recent region list.

ClientToken String No 123e4567-e89b-12d3-a456-426655440000

The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The ClientToken value must contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.

HpcClusterIds String No ["hpc-xxxxxxxxx", "hpc-yyyyyyyyy", ... "hpc-zzzzzzzzz"]

The IDs of the HPC clusters.

You can specify a JSON array that consists of up to 100 HPC cluster IDs. Separate multiple HPC cluster IDs with commas (,).
