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.

Because "Preemption scheduling" is actually for the jobs in different queues. LSF today has no such feature or concept of in-queue preemption. the new feature maybe work like this: define a INQUEUE_PREEMPT=[[userA,80%] [userB,20%]] ... For example...

Allow Mass Changes of Both License Services and Clusters

In Cacti at page Console > Management > Devices, you have a dropdown option to "Change Settings". From here, you can select multiple devices, and then change select settings. It would be nice to be able to make these same changes for RTM obj...

cores limitations using affinity

In our cluster, we are very often impacted by jobs under reserving cpus (using -n option of bsub). for ex, we have a user group using a GUI for days. When the user close the GUI, it fires thousands of tar/bzip2 -9 to compress log files, making exe...

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 t...

Add Tooltips for Various LSF Attributes

Today, on many Cacti pages, table headers include tooltips that explain the dimensions that are displayed in the table. It would be nice to have that for the 13 standard load indexes in LSF, and be able to pull the description from lsf.shared for ...

Have LSF track the number of status changes and requeues for a job over time

Basically, right now, there is no way to look at LSF's jobInfo record to know how many times a job has been requeued via either a pre-exec/jobstarter failure, or from a manual requeue. Additionally, there is no way to determine how many times a jo...

Threshold for over allocation in License Scheduler

Based on the license availability and the demand from certain project(s), LSF License scheduler can allocate more license to a project, then its define share of licenses. If limits are defined, it leads to under utilization and wastage of licenses...

Simplify the Removal of a specific select string or rusage from a running or pending job

It would be nice if we simply had the ability to bmod away a reservation without having to reconstruct the entirety of the bsub -R "blah" syntax. I would much prefer to do something like: bmod --remove-reservation mylicense [options] jobid ... V...

Enable override of -u flag to docker in LSF

The docker LSF integration would be more useful if the user inside the container was not forced to be LSB_SUB_USER. It's not clear where this -u flag is being added to the docker command by LSF. The construction of this flag does not appear to be ...

Increase MAX_JOBID in PE environment - 4194303 too low

When using PE in LSF the maximum job ID is 4194303.We have already cycled through the range in 12 months and we'll likely do it twice this year.Having jobs with duplicate IDs causes a lot of problems with things like job accounting.
