Re: [Matlab-emacs-discuss] Matlab-Shell & Sun Grid Engine

[David C. <dav...@fr...>]

Hi Eric,

 

Many thanks for your swift reply !!

In fact I've just realised things are more complicated than that. Eventually
I did manage to submit matlab as a Sun Grid Engine job, but then, the
communication between emacs and matlab is broken because the two processes
do not necessarily run on the same machine.. So it looks like the only way
is to submit emacs as a job first, and start matlab normally from there (on
the same machine !).

 

On a slightly different note, I've been using EmacsLink for years, but only
now am I starting to look at matlab-emacs. Undoubtedly there are a few
things I need to learn and to get used to, but one thing that I miss
terribly is the ability to "see" where my breakpoints are in the source
code, pretty much in the same way as mlint warnings are reported (with
linemark.el).

 

Is this feature not supported ? Or is something broken in my configuration ?

 

Cheers,

David.

Hi,

 

  The variable 'matlab-shell-command' needs to be a string that represents a
single executable.  In your case, you want it to just be "qrsh".   You would
then set 'matlab-shell-command-switches' to be '("-b" "y" "-q" "single" "-V"
.) with all your switches spelled out.  It seems outlook is messing with my
'quote' marks, so you will need to type it in and not copy what I typed
here.

 

Good Luck

Eric

Hi everyone,

 

I'm having a simple problem configuring matlab-shell-command.

The thing is I actually never run matlab locally on the machine I am logged
on, but matlab is submitted as a job to a large pool of linux machines with
the Sun Grid Engine.

 

In other words, I don't use the "matlab" command at the shell prompt, but
instead I use something like:

 

qrsh -b y -q single -V -cwd -noshell matlab

 

Now, everything works fine by default, if I set matlab-shell-command to
"matlab".

But if I set matlab-shell-command to "qrsh -b y -q single -V -cwd -noshell
matlab", a problem occurs in matlab.el (matlab-shell function), and more
specifically on this line :

 

(switch-to-buffer

      (apply 'make-comint matlab-shell-buffer-name matlab-shell-command

                           nil matlab-shell-command-switches))

 

which returns the error message

Searching for program: no such file or directory, qrsh -b y -q single -V
-cwd -noshell matlab

 

As a workaround, I have tried defining an alias in my .cshrc, something
like:

alias sge_matlab 'qrsh -b y -q single -V -cwd -noshell matlab'

 

and this works to manually start matlab from the shell. But again if I set
matlab-shell-command to "sge_matlab", then I get

apply: Searching for program: no such file or directory, sge_matlab

 

So what is the proper way to get everything to work in my case ?

 

Many thanks in advance !

Cheers,

David.
