New submission (application) templates

Edit online

New default submission templates have been added for this release.

H2O

H2O is an open source machine learning platform. It supports a clustered mode which can be run across nodes in your LSF cluster. The LSF Application Center application template will help you deploy H2O across your LSF cluster and allow you to run R and python applications.

Requirements for H2O:
The H2O application template is included in the default installation of LSF Application Center 10.2 Fix Pack 9. It can be found under the Deep Learning directory in LSF Application Center. Mark the LSF hosts eligible to be H2O hosts with a boolean resource (for example, h2o) and have the h2o.jar available on those hosts in the same directory. Provide this information when publishing the application template. Submit the template to start the H2O cluster which starts up the H2O flow GUI that can be connected directly through LSF Application Center. Alternatively, users can connect and run their Python or R applications using:
  • R: The h2o R library is installed. In R shell:

    library(h2o), h2o.connect()

  • Python: The h2o python library is installed. In the Python shell:

    import h2o, and run h2o.connect()

Tensorflow

Using the new Tensorflow submission (application) template included in 10.2 Fix Pack 9, users can start Tensorflow jobs on available LSF servers, from LSF Application Center.

When an administrator attempts to publish a Tensorflow template, they are prompted to ensure LSF has been configured to run jobs in Docker containers (following instructions at https://www.ibm.com/support/knowledgecenter/en/SSWRJV_10.1.0/lsf_docker/lsf_docker_prepare.html).

The administrator is prompted at the same time to enter a directory for download of the tutorial (MINST_Training). The path must be accessible from LSF servers. For example: /share/mldl.

Jupyter Notebook

Using the new Jupyter submission (application) template included in 10.2 Fix Pack 9, users can start Jupyter Notebook on an available LSF server, and access the Jupyter Notebook from LSF Application Center, using a browser. Anaconda must be installed in a shared directory which can be accessed by users on any LSF server.

Notification for jobs submitted through IBM Spectrum LSF commands bsub or bmod

Edit online

The -notify option on bsub and bmod commands can deliver job status change notifications to all LSF Application Center channels (browser, desktop client, email, mobile).

New version of IBM Spectrum LSF mobile client

Edit online

A new version (1.0.5) of the IBM Spectrum LSF mobile client is available on the Apple App Store and the Google Play store. This version includes some bug fixes and is supported on LSF Application Center 10.2 Fix Pack 9.

LSF Application Center SDK disabled by default

Edit online

As of version 10.2 Fix Pack 9, the IBM Spectrum LSF Application Center SDK is disabled by default. To enable the SDK, define ENABLE_AC_SDK=Y in the pmc.conf configuration file.
