OGF Public Comments

Public comments are a very important part of the OGF document approval process.  Through public comments, documents are given scrutiny by people with a wide range of expertise and interests. Ideally, a OGF document will be self-contained, relying only on the other documents and standards it cites to be clear and useful.  Public comments of any type are welcomed, from small editorial comments to broader comments about the scope or merit of the proposed document.  The simple act of reading a document and providing a public comment that you read it and found it suitable for publication is very useful, and provides valuable feedback to the document authors.

This is a good primer that provides information for making comparisons. This helps one to understand the relationships and some of the the execution models.

I seeing more ReST based web services and wonder if there is any support for that for job submission? It may help with the execution and monitoring of activities from within a browser context.
Thanks.

You state in Section 3.2 that a shared file system between submission host and compute hosts is assumed. In theory, this is not demanded by DRMAA and also not by the DRM systems that have DRMAA support (SGE, Condor, GridWay, ...). You might be right from a practical perspective - all DRMAA users we know have a shared FS cluster model.

Section 3.2.2 might give the impression that the DRMAA library needs to be installed "on the submission host and across the cluster". It only needs to be installed on the submission host.

I like Section 3.2.4. It clearly states the idea of DRMAA. You might want to add a sentence about high-level API's (such as SAGA) that rely on DRMAA support in the scheduler for the implementation.
