Welcome aboard...
1) how will the security be treated?, what will be used for authentication/authorization?
See the HPCBP specification for details. But username & password over server side TLS is one option. Another is mutual TLS using X.509 certificates. Some groups are providing both endpoints... others just the one.
2) what sort of jobs will be submitted and by what kind of client(s)? Would be useful to be able to check out an example jsdl job request.
Provide the JSDL of a job that will run on your system so that others can test your endpoint using that JSDL. Arrange on a peer to peer basis to support other jobs as requested.
Is the HPCBasicProfileComplianceTester page already functional?
Yes.
3) What are the plans related to data stage in?
Not covered in the specification. Some prototyping work going on as part of a File Staging specification. See posting about a month ago. Also very draft specification on gridforge.
4) In general, what is the communication channel for the SC07 preparations, where can we post our questions? Is it the ogsa-hpcp-wg@ogf.org mailing list?
This mailing list. There will be a call next Thursday. Details to be circulated. Steven
