[more info] Split LSF_TMPDIR into 2 different parameters: job's TMPDIR and LSF daemons' working directory

Have 2 different parameters to specify:
1) Job's temporary directory TMPDIR
2) LSF daemons' working directory where they core dump in case of fail, or sbatchd creates the .XXX.fanout and the .XXX.sbd directories.

At the moment, both aspects are affected by the same parameter LSF_TMPDIR.

    Hi Jeff,

    I think that new feature included in LSF 9.1.3 fits our needs. Thanks for improving this wonderful product.

    Can you close the RFE for me?

    Best regards,
    Juan Palomino

    Hi Juan,

    Currently, LSF 9.1.3 already has a feature that I believe meets the use case that you described.

    You can utilize the LSB_JOB_TMPDIR parameter to designate a directory under which jobs can create job-specific temporary directories. At the same time, you can define LSF_TMPDIR as the LSF daemon's working directory where core dumps will be placed and where sbatchd creates the .XXX.fanout and .XXX.sbd directories.

    For example I can set:
    LSB_JOB_TMPDIR=/scratch
    LSF_TMPDIR=/tmp (this is actually the default setting)

    Then as I run jobs with LSF, my directories may look something like this:
    [jeff]$ ls -la /scratch
    total 12
    drwxrwxrwx 3 jeff dev 4096 Oct 15 15:43 .
    drwxrwxrwx 10 root root 4096 Oct 15 11:20 ..
    drwx------ 2 jeff dev 4096 Oct 15 15:13 820.tmpdir

    [jeff]$ ls -la /tmp
    total 2424
    drwxrwxrwx 4 jeff dev 4096 Oct 15 15:43 .
    drwxrwxrwx 10 root root 4096 Oct 15 11:20 ..
    -rw-r--r-- 1 jeff dev 52 Oct 15 15:13 .1555530476.820.hostAffFilePath
    -rw-r--r-- 1 jeff dev 44 Oct 15 15:13 .1555538476.820.hostFilePath
    -rw------- 1 root root 15040512 Oct 15 15:43 core.22750
    -rw-r--r-- 1 root root 15 Oct 15 15:44 .sbd.jeffcluster.820.rusage
    -rw------- 1 root dev 16 Oct 15 15:41 .tmp.shm
    drwx------ 2 root root 4096 Oct 15 15:43 .jeffcluster.fanout
    drwx------ 2 root root 4096 Oct 15 15:43 .jeffcluster.sbd

    You can see that in LSB_JOB_TMPDIR (/scratch), there is a job-specific temporary directory named 820.tmpdir. Then, in LSF_TMPDIR (/tmp), there are the .XXX.fanout and .XXX.sbd directories.

    These two parameters can be set in lsf.conf to fully control the job-specific temporary directories and the directory for LSF daemons. When using these two parameters, make sure the permissions are correctly set for designated directories. Also, after changing these parameters in lsf.conf, run "badmin hrestart all" to make the new settings take effect.

    I have found that the LSB_JOB_TMPDIR parameter is not included in the LSF admin/reference guide. I am working on including them into the guide.

    For reference, you may look at the document below for information on LSB_JOB_TMPDIR. This is a guide for LSF running on GPFS which is not the file system that you're using, but the information may still be helpful as a future reference.
