HP XC System Software Administration Guide Version 4.0

Note:
You must specify an absolute pathname for the log file; it must begin with the / character.
You can choose to isolate this data log on one node or in the /htpc_cluster directory so
that all nodes can access it. However, this log file must be accessible to the following:
• Nodes that run the slurmctld daemon
• LSF
• Any node from which you execute the sacct command
Note:
Ensure that the log file is located on a file system with adequate storage to avoid file
system full conditions.
This example uses the file /hptc_cluster/slurm/job/jobacct.log, which is the
default and recommended file.
Ensure that the configured job accounting log directory exists.
3. Determine the value for the Job Account Polling Frequency parameter.
For jobs that run for a very short time (that is, shorter than the polling frequency), the values
of psize and vsize may be sampled before the program has expanded to its normal
working size.
You can set this parameter to a value indicating the polling interval (in seconds). The majority
of the jobs run should have longer run times than this value.
The default value is 30.
Setting this value to 0 causes the sacct command always to report values of 0 for psize
and vsize.
4. Use the text editor of your choice to edit the /hptc_cluster/slurm/etc/slurm.conf
file as follows:
a. Locate the parameter JobAcctType:
JobAcctType=
b. Set the value of JobAcctType to enable job accounting as follows:
JobAcctType=jobacct/log
c. Locate the parameter JobAcctLogfile:
JobAcctLogfile=
d. Set the value of the JobAcctLogfile parameter to designate the log file you chose in
step Step 2:
JobAcctLogfile=/hptc_cluster/slurm/job/jobacct.log
Note:
Ensure that the leading hash character (#), which designates a comment line, is removed.
e. Set the value of the JobAcctFrequency parameter to designate the polling frequency;
this example uses a frequency of 10 seconds:
JobAcctFrequency=10
f. Verify that this portion of the slurm.conf file resembles the following (the changes
are shown in bold):
