Example: Convert Multi-Queue Statements into One
The old method of setting multiple queue statements into a single submit description to create variance between submitted jobs is deprecated. However, the ability to easily submit multiple jobs with variance is still possible with a single queue statement. The following examples will show how one can convert the older syntax to the improved single queue statement.
Note
The following example submit files are not designed to be useable but rather a demonstration of how the old syntax can be converted.
A Job Per File
The following example shows a submit file using multiple queue statements to
submit jobs with differing input files which can easily be done with a single
queue statement. This example assumes the working directory contains the files
example1.in
and example2.in
.
executable = /bin/cat
arguments = $(filename)
transfer_input_files = $(filename)
#==========Replace=========
# Old Syntax
filename = example1.in
queue
filename = example2.in
queue
#==========================
# Converted Syntax
# Submit one job per file matching *.in
queue filename matching files *.in
Jobs with multiple variables
The following two examples show how multiple variables can be given variance in a single queue statement.
executable = quadratic.sh
arguments = "$(A) $(B) $(C)"
#==========Replace=========
# Old Syntax
A = 3
B = 1
C = 10
queue
A = 2
B = 8
C = 4
queue
#==========================
# Converted Syntax
# Submit one job for each row of data
queue A,B,C from (
3, 1, 10
2, 8, 4
)
Variable Cadence
In the following example, the capacity
variable uses each assigned value for
two jobs with a varying type
variable.
executable = science.py
arguments = "$(capacity) $(type)"
#==========Replace=========
# Old Syntax
capacity = 100
type = "soft"
queue
type = "hard"
queue
capacity = 42
type = "soft"
queue
type = "hard"
queue
#==========================
# Converted Syntax
type = $CHOICE(STEP,"soft","hard")
queue 2 capacity from (
100
42
)
