kaldi parallelism

This post focus on

run.pl

of local parallelism.

run.pl <options> <log-file> <command>

<options>

: a job range specifier (e.g.

JOB=1:4

), the identifier name needn’t be

JOB

, and is uppercase conventionally.

<log-file>

: file name for array jobs must contain identifier of the array (e.g.

foo.JOB.log

)

<command>

: basically, can be anything. You need to escape pipe symbol

|

as

\|

, and other things like

;

and

>

.

examples:

run.pl foo.log echo "hello, kaldi"

run.pl JOB=1:4 foo.JOB.log echo "hello, job: JOB"

run.pl test.log echo "foo" \| sed `s/f/F`

run.pl

will replace the

JOB

in the command line with a number within the range.
