Dear Jon,
Congratulations for your work!
I tried to benchmark my computers with Matlab 6.x (versions 6.0.0.88 R12 and
6.1.0.450 R12). Do I need a particular toolbox installed? The matlab command
(indicated for Matlab 6.x) was not recognized, but the bench command was:
>> matlab(5)
??? Undefined function or variable 'matlab'.
>> which matlab
matlab not found.
>> for I=1:5
T(I,:) = bench;
end
>>
I understand I need to close all other programs when benchmarking. Should I
disable the antivirus (Norton) program too?
With best wishes,

%%Dear Kent, Geraint, Volkmar, .......
%%
%%I was due to post the results of the benchmarking process just after to
%%Christmas, but got delayed due to a number of nice and not-so-nice
%%events. Basically we got hacked, and our entire SUN network needed to be
%%re-installed. Fortunately no data was lost, and we're back up and
%%running now.
%%
%%Anyway, following the recent activity on the mailbase, I've decided to
%%post the results at http://painweb.tripod.com (sorry about the banner
%%advertising, but our webserver is still down after the attack).
%%
%%This is always going to be a works in-progress sort of site, since I
%%hope people will continue to send me new stats as and when they get new
%%machines.
%%
%%I hope you find the information presented both interesting and useful
%%when it comes to making an informed choice about which platform to run
%%SPM on. I'm sure people will have questions and comments, and I will try
%%to answer these as quickly as possible.
%%
%%Yours,
%%
%%Jon.

%%
%%Dear SPMers,
%% I appear to be one of the lonely who still advocates buying Sun
%%workstations over other boxes. (I think I am going to talk to my rep
%%about
%%commissions ;-)
%%
%%While Suns are a little slower (note there is a new model out - Sun
%%Blade
%%2000) than PCs, I tend to weigh stability as important as speed - and we
%%just never have any problems with the Suns - they are up for months at a
%%time. Seeing as our normal procedure is to start an SPM batch process
%%and
%%go home, I don't really mind if the process take till 2:00am or till
%%5:00am
%%to finish, what I like is that it reliably finishes on the Suns.
%%
%%Also, we have DVD-RWs installed in our all Sun Blades and they are also
%%very
%%stable.
%%
%%New academic pricing lists the Sun Blade 1000 at ~$7k US. Note that
%%they
%%also sell a new 24inch LCD for about $2k US.
%%
%%Just to echo other list members sentiments, seems you already have lots
%%of
%%experience maintaining Suns, adding another (perhaps unfamiliar)
%%operating
%%system might be a recipe for sys admin headaches.
%%My two cents.
%%
%%Best regards,
%%Kent

%%Hi David,
%%
%%Dual Xeon (P-IV) workstations are also worth looking at; they're cheap
%%and
%%with SMT the new Xeons should have even more zip (though Matlab is
%%single
%%threaded, you can run more processes). My 1.8GHz*2 Linux/W2K non-SMT
%%system
%%comfortably outperforms comparable Sun Blade & Ultra 60 boxes. Even
%%bolting
%%on a DVD-RW for backup, lots of local storage and a big flatscreen
%%monitor,
%%it's not going to be much more than £4K for a typical configuration,
%%which
%%is a lot cheaper than Sun...
%%
%%Best,
%%
%%Geraint
