Summary: Please relate experience with NQS, DQS, DNQS, LSF

From: Norbert Juffa (
Date: Tue Jan 03 1995 - 14:43:21 CST

I am currently in search of network batch software for our network of Sun
workstation. As I am new to this kind of software, I have turned to the net
for information on the available packages.

Freely available are: NQS, Monsanto-NQS, DNQS, DQS and
                        Condor, PVM
Commercial systems are: LSF, IBM Load Leveller, CODINE, HP Task Broker, ...

After a first posting, the answers to which gave me an idea of what software
is available for network batch processing, I sent out additional postings to
ask for people's experience with some specific packages. This posting provides
a summary of the responses to these postings. I include my original news
postings here to provide the readers of this summary with a context.

Posting to comp.parallel, comp.unix.misc, comp.unix.large:

>Some days ago I asked on the net about software that supports splitting a

>and allow monitoring the work in progress.

> file dated Aug 29, 1994

Posting to comp.sys.sun.misc:

It seems that in my posting to comp.sys.sun.misc I inexplicably exceeded the
80-column format (has been corrected in the copy above). For that I apologize.

So far I have received seven email replies. I'd like to thank Francois P.
Thibaud <>, Jingwen Wang <>,
Matthias Linke <>, Glenn Malling
<>, Kenneth J. Bongort <>, Jim Pryune
<>, Scott Strecker <> for taking the time
to answer my questions. Their email replies are included below and have been
only edited to delete my original postings that were quoted in the replies.

Again, thanks to all respondents.

Hi !

I am currently writing a small paper on that subject (not yet ready;
I'll send it to you if you are interested at mid January or so). I
believe that none of the packages you mentionned will do what you
want, namely "automatically deal with network problems and machines
going down, allow the user to add and delete jobs from/to the submit
queue, allow scheduling of jobs to certain machines and allow
monitoring the work in progress".

In fact, to my knowledge, *NOTHING* exists that would do what you
want !!! I have been working on something to handle errors. PVM 3.3:

  title = "PVM 3 User's Guide and Reference Manual (PVM-3.3.4)",
  author = "Geist, Al and Beguelin, Adam and Dongarra, Jack and Jiang,

  address = "Oak Ridge, Tennessee 37831",
  year = "1994",
  month = "September",
  note = "ORNL/TM-12187 (at URL:

offers some partial solutions.

I would be most interested in the feedback you will get from the Net
as well as you experiences in this field !

Kind Regards !

HalliHallo !!

There is a paper comparing the main batch sytems like NQS, DQS ,CODINE...
You can find it at

Enjoy it!

    I am sure NQS does not quite do what you want. I would suggest you try LSF.
A lot of NQS users have replaced their NQS by LSF.

    LSF is from Platform Computing. Send email to for a free
evaluation copy.

    If you need information on different packages that does similar things as
LSF, read the following information :


    cd distrib/lsf/doc

    There are also many other files in this directory that describe LSF.

I believe that IBM has a version of Load Leveler for SUN. I could be
wrong but I think I remember seeing a product announcement for it.

Here's another answer in category two:

You might also be interested in checking out Condor which was developed
here at the University of Wisconsin. It is a batch system along the lines
of NQS/DQS, but has a few extra features. In particular, Condor can do
checkpointing and migration of your jobs which allows it to use spares
cycles from users desktops while they are away, and gives you some extra
reliability in case of failure. You can get Condor free via ftp from
