I'm looking into buying a laptop which to run IDL under Linux. Does
anyone have a recommendation on the amount of memory I should get? I'm
thinking that at least 64 MB would be appropriate.
Cheers,
Liam.

In the Solaris case, the 7MB total size is right, but the size in
physical memory (resident stack size) is 2.8MB. What size is given
by the WinNT output? Perhaps it does not include the pages in the
swap file?

I'm not sure about the situation via Windows NT versus Solaris, but I have
noticed this sort of behavior on simple routines that were compiled on
different platforms. It may have more to do with the platform's compiler than
it does with IDL.
Just my $0.02 worth,

I don't want to start a platform war or anything, but I've noticed that IDL
on Windows NT doesn't use much memory when it starts up - around 3 MB for
5.0b. What on earth does IDL use all that memory for on Solaris?

That also depends on what routines etc. you precompile on startup.
However, on Linux it's approx. 5MB on startup.
And the size of 5.0b is definitely a vote against it, at least for me.

I thought this would be a good time to point out something that
really suprised me...IDL 4.0.1 on a Sun under Solaris 2.5 took
approximately 7MB of memory when started. IDL 5.0b takes 13MB!!
Inflation I guess.

I am running kernel 2.0.27 / idl5.0 beta with 32 megs, and the machine
swaps a little bit, especially if netscape is running, but it does
very good with 32 megs. 64 should do fine, but of course you should always
get the maximum you can :-)
