by Jim Pruyne 29 Oct '05

29 Oct '05

Minutes from October 26 '05 Telecon Attendees --------- Jim Pruyne Toshi Nakata Heiko Ludwig Asit Dan Discussion ---------- - Let's move the meeting time one hour earlier because of daylight savings time in the US and EU. We'll do that starting next week. - The URL for the public comments has been sent out. - Toshi to group the large comment list from Stephen Pickles into the grammar ones vs. the ones that require discussion. - Managing the responses could be handled a little more formally, so we should be more clear on exactly what to be posted in a reply on the public comment tracker. - There was some concern at GGF that people could not tell how we were making decisions. Heiko proposes that we make our process clear in an e-mail to the mailing list. Jim will do this.

A Highly available, Fault tolerant Co-scheduling System
by Jon MacLaren 24 Oct '05

24 Oct '05

For those of you not in Boston this week, I gave an overview of a Highly available, Fault tolerant Co-scheduling System, which I've built at LSU. We successfully used this system at the iGrid 2005 meeting to co-schedule 10 compute jobs and 2 Calient DiamondWave switches. The system uses the Paxos Commit protocol (Lamport, Gray) to overcome the problems associated with distributed 2-phase commit. The co- scheduler, when deployed as 5 processes, has a mean-time-to-failure of about 12 years. The software is available for download, but, as I said at the meeting, I'm still writing up the installation instructions. There is a mailing list about the work, though. And if you go to the web- site for this stuff, you can sign up, and receive updates. The link is: http://www.cct.lsu.edu/personal/maclaren/CoSched/ Cheers, Jon MacLaren.

Usage Scenarios Document
by Stephen M Pickles 04 Oct '05

04 Oct '05

The GRAAP Usage Scenarios document "Usage Scenarios for a Grid Resource Allocation Agreement Protocol" never actually been published. It occurs to me that now might be a good time to remedy this. Flushing out public comments on the use cases could be useful while the working group is considering its next steps. It would also make it possibly to cite the document properly. Would anyone object if I took steps to get this document into the GGF Editor pipeline as an informational document? Does anyone think it needs another revision first?
