Unix Batch command, and running jobs in queues.

Hello all, I have a quick question. I work in a computational science laboratory, and we recently got a few mac pros to do molecular optimizations on. However, on our normal supercomputers, there are queue systems, mainly PBS.

Anyway, the macs obviously don't have PBS, but I've read about the "batch" and "at" commands in unix.

What I want to do is create a batch file, with multiple commands in it (basically multiple job submit commands), and I want the first one to run immediately, and the second one to run as soon as the first one finishes.

I know that there are different queues used with this command. Accessed by the "-q x" where x is the queue you want. So technically I want to have two different queues cause I want two different jobs to run at the same time.

So I've made a batch file containing four lines that submit four different jobs, like so...

g09 model1.txt &
g09 model2.txt &
g09 model3.txt &
g09 model4.txt &
CTRL-d

However, when I submit it, I don't see anything running when I use the top command, like I do when I just submit the job without using batch. The command I used to submit the batch file was.

batch -q b -f batch1.txt

And I'm in the folder that "batch1.txt" is in. What am I doing wrong?

Thanks in advance...

qstart(8B)								PBS								qstart(8B)

NAME
qstart - start pbs batch job processing at a destination SYNOPSIS
qstart destination ... DESCRIPTION
The qstart command directs that a destination should process batch jobs. If the destination is an execution queue, the server will begin to schedule jobs that reside in the queue for execution. If the destination is a routing queue, the server will begin to route jobs from that queue. In order to execute qstart, the user must have PBS Operation or Manager privilege. OPERANDS
The qstart command accepts one or more destination operands. The operands are one of three forms: queue @server queue@server If queue is specified, the request is to start that queue at the default server. If the @server form is given, the request is to start all queues at that server. If a full destination identifier, queue@server, is given, the request is to start the named queue at the named server. STANDARD ERROR
The qstart command will write a diagnostic message to standard error for each error occurrence. EXIT STATUS
Upon successful processing of all the operands presented to the qstart command, the exit status will be a value of zero. If the qstart command fails to process any operand, the command exits with a value greater than zero. SEE ALSO
pbs_server(8B), qstop(8B), and qmgr(1B) Local qstart(8B)
