IBM Data and AI Ideas Portal for Customers

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.

Extend SessionScheduler being able to manage small parallel application (size up to one node)

Today we have applications/software running in serial mode via session scheduler (runtime per task <<10min) with up to 10000 tasks. These applications/software will migrate to parallel usage soon and we want to keep the SessionScheduler functionality running the 10000 tasks on more than one core per task.

    As discussed offline, this use case can be satisfied directly without using session scheduler. A reservation can be dynamically scheduled/created, and the set of jobs run within it.

    Today, you will be doing something like:
    $bsub -q whatever -n 16 ssched taskfile

    So you could do something like:
    $bsub -q whatever myssched taskfile 16

    where myssched is:

    #usage: myssched taskfile nslots
    brsvsub -D 5 -u $this_user -o -n $2 -N $this_rsv
    while read ss_cmd; do
    bsub -U "$this_rsv" "$ss_cmd
    done < $1
