 | `compute` | string | Name of the compute target to execute the job on. This can be either a reference to an existing compute in the workspace (using the `azureml:<compute_name>` syntax) or `local` to designate local execution. **Note:** jobs in pipeline didn't support `local` as `compute` | | `local` |
 | `resources.instance_count` | integer | The number of nodes to use for the job. | | `1` |
 | `resources.instance_type` | string | The instance type to use for the job. Applicable for jobs running on Azure Arc-enabled Kubernetes compute (where the compute target specified in the `compute` field is of `type: kubernentes`). If omitted, this will default to the default instance type for the Kubernetes cluster. For more information, see [Create and select Kubernetes instance types](how-to-attach-kubernetes-anywhere.md). | | |
+| `resources.shm_size` | string | The size of the docker container's shared memory block. This should be in the format of `<number><unit>` where number as to be greater than 0 and the unit can be one of `b` (bytes), `k` (kilobytes), `m` (megabytes), or `g` (gigabytes). | | `2g` |
 | `limits.timeout` | integer | The maximum time in seconds the job is allowed to run. Once this limit is reached the system will cancel the job. | | |
 | `inputs` | object | Dictionary of inputs to the job. The key is a name for the input within the context of the job and the value is the input value. <br><br> Inputs can be referenced in the `command` using the `${{ inputs.<input_name> }}` expression. | | |
 | `inputs.<input_name>` | number, integer, boolean, string or object | One of a literal value (of type number, integer, boolean, or string) or an object containing a [job input data specification](#job-inputs). | | |
