Object on GPFS

Hello to all. As you might have seen from Jez’s recent post to the mailing list, IBM are hoping to get more involved with the user group in the coming year and part of that will be blogs from developers. This is the first such blog and I’ll be looking at the recently updated red paper for deploying an object store on top of an existing GPFS cluster.

Firstly though a quick introduction. I am a developer in the IBM Manchester Lab and my current role is as an architect for RAS (Reliability, Availability and Servicability), with specific focus on the integration of protocols with GPFS that you should be seeing later this year. In Manchester we have a team of ~10 developers all working towards these future GPFS releases, including James Wormwell, an author on the updated red paper and team lead for the development of the install tool that was made available with the update. Hopefully you should get a chance to meet some of us over the year at the main user group meeting or the various “coffee shop” meetups that we’re hoping to have.

The first speaker of the day was Crispin Keable (CK), HPC Solutions Architect at IBM who presented the latest developments in GPFS 3.5 due to be released at the end of Q1 2012. Crispin’s presentation included:

Minutes from GPFS User Group Meeting 2 – Tuesday 5th April 2011

Hosted by University of Birmingham

 

Barry Evans (OCF) started off with a quick introduction welcoming everyone and outlining the agenda for the day.

Due to technical reasons, the morning agenda changed and the presentations started with a presentation on CEDAR and future projects from AWE and the experiences they have had using GPFS. A number of questions were raised by the audience about their experiences. Jim Roche suggested that the group feeds their requirements into a ‘wish list’ of items that IBM can then use as a formal mechanism to respond to. It was requested that clearance is obtained for the presentation slides and that they are made available retrospectively to group members.

Jez Tucker (Rushes) then presented on the systems used at Rushes and their experiences and challenges. Followed up with questions from the group.
