Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.omics.ai/products/workbench/engines/parameters/on-premises.md). # On-Premises When running on-premises, Workbench integrates [Cromwell](https://github.com/broadinstitute/cromwell) execution engine with [DNAstack's WES service](https://github.com/DNAstack/cromwell-wes-service). This combination enables workflow execution on your infrastructure, whether local servers or cloud providers. The WES service supports all standard Cromwell parameters, documented in the [Cromwell documentation](https://cromwell.readthedocs.io/en/stable/wf_options/Overview/#workflow-options-overview). Additionally, it standardizes the `DELETE_INTERMEDIATE_OUTPUT_FILES` parameter across all supported infrastructure types, allowing consistent intermediate file cleanup when running workflows through [Workbench](https://github.com/DNAstack/dnastack-product-docs/blob/main/docs/workbench/engines/parameters/broken-reference/README.md). ## Available Parameters ### `delete_intermediate_output_files`=`BOOLEAN` Specifies whether to delete intermediate output files. Default is false. If set to true, any File variables referenced in task output sections that are not found in the workflow output section will be considered an intermediate File. Additionally, log files will not be deleted. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.omics.ai/products/workbench/engines/parameters/on-premises.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
