This module is designed to control and execute parallel processing jobs on an HPC cluster using PBS and QSUB. If
qsub=T it will generate a job file and use qsub to place that job in the queue using the appropriate parameter
farm=X gives a recognised program (below) or
hpcmode is not
fork then the qsub
job will call SLiMFarmer with the same commandline options, plus
seqbyseq=T, this will be
run in a special way. (See SeqBySeq mode.) Otherwise
slimsuite=T indicates that
farm=X is a SLiMSuite program,
for which the python call and
pypath will be added. If this program uses forking then it should parallelise over a
single multi-processor node. If
farm=X contains a
/ path separator, this will be added to
pypath, otherwise it
will be assumed that
farm is in
slimsuite=F then farm should be a program call to be queued in the PBS job file instead. In this case, the
jobini=FILE will be added to the end of the farm call. This enables commands with double quotes to be
included in the farm command, for example.
Currently recognised SLiMSuite programs for farming: SLiMFinder, QSLiMFinder, SLiMProb, SLiMCore.
Currently recognised SLiMSuite programs for rsh mode only qsub farming: GOPHER, SLiMSearch, UniFake.
NOTE: Any commandline options that need bracketing quotes will need to be placed into an ini file. This can either
be the ini file used by SLiMFarmer, or a
jobini=FILE that will only be used by the farmed programs. Note that
slimfarmer.ini will not be passed on to other SLiMSuite programs unless
ini=slimfarmer.ini is given
as a commandline argument.
runid=X setting is important for SLiMSuite job farming as this is what separates different parameter setting
combinations run on the same data and is also used for identifying which datasets have already been run. Running
several jobs on the same data using the same SLiMSuite program but with different parameter settings will therefore
cause problems. If runid is not set, it will default to the
hpcmode=X setting determines the method used for farming out jobs across the nodes.
hpcmode=rsh uses rsh to spawn
the additional processes out to other nodes, based on a script written for the IRIDIS HPC by Ivan Wolton.
hpcmode=fork will restrict analysis to a single node and use Python forking to distribute jobs. This can be used even
on a single multi-processor machine to fork out SLiMSuite jobs.
basefile=X will set the log, RunID, ResFile, ResDir
and Job: RunID and Job will have path stripped; ResFile will have .csv appended.
Initially, it will call other programs but, in time, it is envisaged that other programs will make use of SLiMFarmer
and have parallelisation built-in.
In SeqBySeq mode, the program assumes that
basefile=X are given and
farm=X states the Python program
to be run, which should be SLiMSuite program. (The SLiMSuite subdirectory will also need to be given unless
slimsuite=F, in which case the whole path to the program should be given.
pypath=PATH can set an alternative path.)
Seqin will then be worked through in turn and each sequence farmed out to the farm program. Outputs given by OutList
are then compiled, as is the Log, into the correct
basefile=X given. In the case of *.csv and *.tdt files, the header
row is copied for the first file and then excluded for all subsequent files. For all other files extensions, the
whole output is copied.
