Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

License Scheduler ENABLE_DYNAMIC_RUSAGE + FAST_DISPATCH combination

We are troubled by the slow dispatch time of jobs, when the license scheduler is involved. Even after lengthy optimization, the dispatch time remains at 10-25 seconds, which is not good. (note that LMSTAT time and interval is just 3 seconds).

If the following could be done, perhaps we would be able to further increase performance:
1) ENABLE_DYNAMIC_RUSAGE and FAST_DISPATCH to be used simultaneously (currently not possible).
2) Make the interval of the "DEMAND" which is sent by mbatchd to bld configurable (currently set to 15 seconds, according to IBM feedback).
3) Further optimize job dispatch times when licenses are involved in a way that we haven't thought of.
