For your Info, this was part of the message I received with my Mac upgrade
notice for IDL 4.0.1:
> IDL 4.0.1 will also be available for downloading via the Internet in
> approximately 2 - 4 weeks. You can download IDL via anonymous FTP from
> boulder.colorado.edu. IDL downloading instructions are located in the
> pub/idl directory.

> P.S. PC users - want to try IDL for Linux? Send e-mail to "info@rsinc.com"
> and ask for the IDL for Linux demo kit. Our Unix CD-ROM includes the Linux
> version of IDL with special installation instructions.
I seem to remember some folks asking about the availablilty of IDL under Linux.

Could you tell us what version numbers of IDL you were using on each machine
and OS? Also, what are the memory demands of your program, and how frequently
does it produce graphical or disk output?

I agree, the Alpha should have been MUCH faster than it was. Beats me why it
wasn't.

I think I might be interested. I'll get in touch with you directly when I'm
ready to give it a try. Thanks for the post.

Hugh,
No, the code does not use large arrays, in fact I use sequential
calculations
inside double nested for loops. I originally developed this code on the Alpha
IDL for DOS, where large arrays will kill you altogether.
I have two requests for my code, one by someone like yourself, who is
concerned that the DEC-Alpha has been poorly configured. The other is a radar
guy who just wants my model! Our system manager for the DEC-Alpha is an
engineer wearing several hats, so I suspect the DEC machine could be tweeked.
As to your last comment, I'm not really concerned about starting an OS war
either, but I was very impressed with the leap in performance LINUX provided
for
my unfunded, but beloved research.
Thanks for the interest,
Mary Ruth Keller

No user restrictions, but it is a single node installation. No license
manager either. You use the genver program and call up RSI technical
support to get a number of the day. After this it will work for 180
days, and I guess you can call tech support again after this time is
up to get another 180 days. Supposedly this problem will be gone in 5.0.
Some caveats to IDL for Linux:
When I reboot my clock does not get set correctly, and unless I reset
the clock before running IDL, it balks when I try to start it. Also,
CALL_EXTERNAL does not work for the Linux version.
FWIW- I have been having good success the last few weeks running IDL
4.0.1 on my Linux box with RedHat4.0 and kernel 2.0.27.
Good luck.
Alan

I am not sure if this is relevant, but PVWave for Linux uses the license
manager without any problem. However, I am running the manager on a
SPARCstation and I don't know if it would work with the manager under Linux.
The other interesting fact is that floating licenses for Linux cost about half
those for SPARCstations. We use our two SPARC licenses for both the SPARCs and
Linux boxes, so perhaps we have paid over the odds (although we got the licenses
before the Linux version came out). I am told that if you buy Linux licenses
there is nothing to stop them from floating on the SPARCstation and that if we
wanted to buy any of these we would have to sign an undertaking that they
wouldn't be used on the SPARC. It all seems a bit daft to me. A SPARC license
does the same thing as a Linux license, so why charge twice as much?

Bzzt, wrong question, the correct one is:
A Linux license does the same thing as a SPARC license, so why
charge only half the price.
The answer to that, I hope, is clear. Please let us keep low-cost
licenses for "private" machines with decent operating systems!
If that means signing an agreement not to use the licenses on
"professional" machines, then so be it! If you want workstation
licenses, buy them, instead of jeopardizing the affordability of
IDL for private use.
I wonder, though, has anyone tried using the "office" floating
licenses at home, being hooked up through the net?

In retrospect I see that my post was badly worded, and quite easily
misunderstood as a "flame". I apologize for this. The "you" in the
above paragraph was meant to refer to the general public, not you
in particular, Richard.
My assumptions were that linux licenses are cheap because they are aimed
at the "private" market, while workstation licenses are aimed at the
"professional" market. Whether this is sensible given the current
developments is questionable, though. I just wanted to point out that
everyone should be careful not to abuse (and thereby risk loosing) the
cheap "private" licenses, even though they might be identical.

Stein Vidar Haugan

It may be that I have missed the point, or we may have a translation problem
here, but I don't understand any of the points which Stein is trying to make.
Let me try to be clear.
1) I don't think that I ever stated that I WANT workstation licenses. I have
all the SPARC licenses I could want. If I need more seats then I will buy
more PCs and more Linux licenses. In the medium term I would like to get rid
of the SPARCs entirely and save on their maintenance costs. Best of all,
would be for VNI to bring out a Linux for Alpha version. I would then be happy
to get an Alpha motherboard and run it on that.
2) I have no desire to jeopardize the affordability of anything. If my earlier
posting gave the impression that I wanted to see the Linux price increased to
match the SPARC price then I am sorry that it was not clear enough. Why should
I wish anyone (including myself) to pay more for their licenses? I do not
have shares in VNI.
3) Finally, let me make it clear that I agree that Linux is a "decent operating
system". I would rather use it than Solaris any day.
I hope that clarifies the situation.

Currently (4.0.1), no.
The upcoming 5.0 for Linux is rumoured to do so.
