  Submit Scripts  
 Template Submit Scripts
    In order to submit a job, you need both a submit script and render script. Both can be created quickly from scratch using the stock templates. A template submit script can be created quickly via: 
    	      rush -tss > submit-script
    Here's a template submit script written in CSH:

      Csh Template Script 
      #!/bin/csh -f

#
#  S U B M I T
#

source $RUSH_DIR/etc/.submit
rush -submit << EOF
    title       SHOW/SHOT
    ram         250
    frames      1-100
    logdir      $cwd/logs     # "-" to disable
    command     $cwd/render-script
    autodump    done          # off, done, donefail
    cpus        vaio=1@100

    # Optional
    #donemail   you@foo.com   # "-" to disable
    #notes      This is a test
    #state      Pause
    #logflags   keepall
    #frames     1-10=Hold:Hello_world
    #criteria   ( linux | irix | osf1 )
EOF

exit $status

    Submit scripts don't have to be written as csh scripts. Any language that can pipe text into a command can be used to submit jobs. The following shows a template submit script written in Perl:

      Perl Template Submit 
      #!/usr/bin/perl

my $me   = `logname`; chomp($me);
my $pwd  = `pwd`;     chomp($pwd);

open(SUBMIT, "|rush -submit");
print SUBMIT <<"EOF";
    title      mytest
    ram        10
    frames     1-100
    logdir     $pwd/logs
    command    $pwd/render-script 
    donemail   $me
    autodump   off
    criteria   ( linux | irix )
    cpus       +any=10\@100
EOF
close(SUBMIT);

if ( $? >> 8 ) 
    { print STDERR "-- submit failed --\n"; exit(1); }

exit(0);




 Perl: Submit Script, Read Back Jobid

    Here's a perl script that submits a sleep job, and parses back the jobid into a variable, which the perl script can then use for other purposes.

      Perl Submit and Read Back Jobid 
      #!/usr/bin/perl

# Create rush submit file
my $tmp = "/tmp/.submit.$$";
unless ( open ( SUBMIT, ">$tmp" ) ) 
    { print "open(>$tmp): $!\n"; exit(1); }

print SUBMIT <<"EOF";
    title   SHOW/SHOT
    frames  1-10
    command sleep 30
    cpus    +any=1
EOF

unless ( close( SUBMIT ) )
    { print "close($tmp): $!\n"; exit(1); }

# Submit the job, parse out jobid
my $out = `rush -submit < $tmp`; unlink ( $tmp );
if ( $out =~ /RUSH_JOBID (\S+)/ ) { $ENV{RUSH_JOBID} = $1; }
else { print STDERR "$out\nSubmit failed.\n"; exit(1); }

print "RUSH_JOBID IS NOW $ENV{RUSH_JOBID}\n";
exit(0);




    Here's a simple C program that submits a sleep job.

      C Programming Example: Simple Submit 
      #include <stdio.h>
main()
{
    FILE *fp;
    if ( ( fp = fopen("my-submit", "w") ) == NULL )
        { perror("my-submit"); exit(1); }
    fprintf(fp, "title      TEST\n"
                "ram        1\n"
                "frames     1-10\n"
                "command    rush -sleep 300\n"
                "cpus       +any=10\n");
    fclose(fp);
    system("rush -submit < my-submit");
}




    Here's a more complex C program that acts as both a submit and render script, using recursion to invoke itself. It also uses pipes to prevent creating the temporary file used to submit the job in the previous example. Note that it's critical to invoke this program with an absolute path so the program can invoke itself correctly from other machines.

      C Programming Example: Submit and Render 
      #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>
