Working with eexec Working with eexec About eexec The eexec program runs on the execution host at job start-up and completion time and when checkpointing is initiated. It is run as the user after the job environment variables have been set. The environment variable LS_EXEC_T is set to START, END, and CHKPNT, respectively, to indicate when eexec is invoked. If you need to run eexec as a different user, such as root, you must properly define LSF_EEXEC_USER in the file /etc/lsf.sudoers. See the Platform LSF Reference for information about the lsf.sudoers file. eexec is expected to finish running because the parent job process waits for eexec to finish running before proceeding. The environment variable LS_JOBPID stores the process ID of the process that invoked eexec. If eexec is intended to monitor the execution of the job, eexec must fork a child and then have the parent eexec process exit. The eexec child should periodically test that the job process is still alive using the LS_JOBPID variable. Using esub and eexec to pass data to execution environments Limitation If esub needs to pass some data to eexec, it can write the data to its standard output for eexec to read from its standard input (stdin). LSF effectively acts as the pipe between esub and eexec (e.g., esub | eexec). Standard output (stdout) from any esub is automatically sent to eexec. Since eexec cannot handle more than one standard output stream, only one esub can use standard output to generate data as standard input to eexec. For example, the esub for AFS (esub.afs) sends its authentication tokens as standard output to eexec. If you use AFS, no other esub can use standard output. 388 Administering Platform LSF
C H A P T E R 31 Configuring Job Controls After a job is started, it can be killed, suspended, or resumed by the system, an LSF user, or LSF administrator. LSF job control actions cause the status of a job to change. This chapter describes how to configure job control actions to override or augment the default job control actions.
