IBM Data and AI Ideas Portal for Customers


This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Update lsf.shared with up-to-date CPU models

The file `lsf.shared` provided with Spectrum LSF is outdated. The CPU models listed seem to be 10 years old and older and there don't seem to be any updates from IBM. I suggest that IBM regularly updates this file with up-to-date CPU models and meaningful CPUFACTOR values or provides a way to automatically construct up-to-date entries e.g. through a web based wizard

    The host type/models/factors are intended to be site customizable. A long time ago we did refresh this file with each update, but many sites complained that our updates broke changes they had made to the files and others debated the appropriate benchmark to use, and thus the appropriate value of cpufactors. The best practice guidance is to set the slowest machine in your environment to cpuf=1 and scale up from there. "lim -t" shows the architecture string and matches to the configured information.


    $ lim -t
