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...
