LSF_DATA_BSUB_CHKSUM

For jobs with a data requirement, this parameter enables the bsub and bmod commands to perform a full sanity check on the files and folders, and to generate the hash for each file and folder.

Syntax

LSF_DATA_BSUB_CHKSUM=Y | y | N | n

Description

For jobs with a data requirement, this parameter determines how LSF performs the following operations on the corresponding files or folders:

  • Sanity check to see if the files or folders exist
  • Check whether the submission user can access the files or folders
  • Discover the size and modification times of the files or folders
  • Generate a hash for each file or folder

If LSF_DATA_BSUB_CHKSUM is set to y or Y, the bsub and bmod commands perform all the operations on the files or folders.

If LSF_DATA_BSUB_CHKSUM is set to n or N, all the operations on the files or folders occur at the transfer job. This reduces the amount of time that the bsub or bmod commands take to submit or modify the job, which equalizes submission performance between jobs with and without data requirements.

You can force the bsub or bmod command to perform all operations on the files or folders by specifying the -datachk option with the bsub or bmod command. The -datachk option can be specified only with the -data command option.

Default

N. Full checking for the files or folders are performed at the transfer job and not by the bsub or bmod command.
