Try GNU parallel it's awesome, and exactly the thing you are looking for. It allows you to set number of processes running among many things. I use it a lot, and can't recommend it enough.

=head2 DIFFERENCES BETWEEN parasweep AND GNU Parallel
|
||||
|
||||
B<parasweep> is a Python module for facilitating parallel parameter
|
||||
sweeps.
|
||||
|
||||
A B<parasweep> job will normally take a text file as input. The text
|
||||
file contains arguments for the job. Some of these arguments will be
|
||||
fixed and some of them will be changed by B<parasweep>.
|
||||
|
||||
It does this by having a template file such as template.txt:
|
||||
|
||||
Xval: {x}
|
||||
Yval: {y}
|
||||
FixedValue: 9
|
||||
# x with 2 decimals
|
||||
DecimalX: {x:.2f}
|
||||
TenX: ${x*10}
|
||||
RandomVal: {r}
|
||||
|
||||
and from this template it generates the file to be used by the job by
|
||||
replacing the replacement strings.
|
||||
|
||||
Being a Python module B<parasweep> integrates tighter with Python than
|
||||
GNU B<parallel>. You get the parameters directly in a Python data
|
||||
structure. With GNU B<parallel> you can use the JSON or CSV output
|
||||
format to get something similar, but you would have to read the
|
||||
output.
|
||||
|
||||
B<parasweep> has a filtering method to ignore parameter combinations
|
||||
you do not need.
|
||||
|
||||
Instead of calling the jobs directly, B<parasweep> can use Python's
|
||||
Distributed Resource Management Application API to make jobs run with
|
||||
different cluster software.
|
||||
|
||||
|
||||
=head3 Future support in GNU Parallel
|
||||
|
||||
B<Future> versions of GNU B<parallel> may support templates
|
||||
with replacement strings. Such as:
|
||||
|
||||
Xval: {x}
|
||||
Yval: {y}
|
||||
FixedValue: 9
|
||||
# x with 2 decimals
|
||||
DecimalX: {=x $_=sprintf("%.2f",$_) =}
|
||||
TenX: {=x $_=$_*10 =}
|
||||
RandomVal: {= $_=rand() =}
|
||||
|
||||
that can be used like:
|
||||
|
||||
parallel --header : --tmpl my.tmpl {#}.t myprog {#}.t ::: x 1 2 3 ::: y 1 2 3
|
||||
|
||||
Filtering may also be supported as:
|
||||
|
||||
parallel --filter '{1} > {2}' echo ::: 1 2 3 ::: 1 2 3
|
||||
|
||||
which will basically do:
|
||||
|
||||
parallel echo '{= $arg[1] > $arg[2] and skip() =}' ::: 1 2 3 ::: 1 2 3
