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.
LSF / Extend "span[hosts=xx]" capability to several hosts to optimize cpu utilization in exclusive context
There is no way today to optimize CPU utilization over several hosts, i.e. to specify on how many servers the job should be dispatched, and let LSF use all available cpu on these hosts. This works fine with 1 single host, using cpu range and "span...
1. By design, if the loadSched condition is not satisfied, no jobs can be dispatched to the host. Even if we submit a job which will not use the lacking resource, the job can't be dispatched to the host, either. 2. We think this is a waste of the ...
Can bstop release slots in order that other jobs can start on the same host ?
Here is an example. I tried the following case. gnx5561 has been booked by advanced reservation: RSVID TYPE USER NCPUS RSV_HOSTS TIME_WINDOW res0 group res0 3/4 gnx5561:3/4 7/28/18/0-7/30/12/0 I have launched one job reserving 3 cpus (857274). It ...

Not under consideration
currently, the directory use for job graphs (specified in the "Console->Grid Settings->Paths->Grid Cache Dir" field) is never clean up. can you please add feature to purge this directory to avoid disk space saturation ?
Hello, 1st: not possible to update host resources using bconf although that it is documented in the man pages & bconf help. see ex1 "in use case example" 2nd: another way should be to have an extra sub command to add or remove a specific resou...
We want to ensure that jobs get the CPU time according to the amount of slots requested, especially on nodes shared by multiple jobs. This has always been an important goal in HPC environments. To achieve this we can use affinity, however CPU affi...
Currently there is a large list of -o options, which are hugely beneficial. We have a large bjobs -o <long list> -json report that is frequently run for metrics and query reduction (to provide an API to get cached data) but we have to update...
We are facing the need to limit access to certain data columns/fields in LSF Explorer for certain roles. In our environment a few different teams will make use of the reporting capabilities of LSF Explorer in different scopes. Nevertheless, LSF Ex...
