Arlindo,<br><br>Thanks for the advice! I've seriously been thinking of just getting a Mac Mini. It's more than I'd like to spend, but I'd be getting a system that would have a long useful lifetime. (Also, the $599 base model comes with an core i5 processor, as opposed to the dated (Q2/2010) Atom D525 which is in most of the systems I have been looking at.) <br>
<br>Also, thanks for the info on RAM and using an SSD! I really like the speed and noise benefits of an SSD.<br><br>-Joe<br><br><div class="gmail_quote">On Thu, Oct 20, 2011 at 9:37 PM, Arlindo da Silva <span dir="ltr"><<a href="mailto:dasilva@alum.mit.edu">dasilva@alum.mit.edu</a>></span> wrote:<br>

Hello fellow users and GrADS developers!<br><br>I'm researching to purchase a new machine to run GrADS. I'm buying a new machine because I don't keep my computers on 24x7 and I would like a more reliable method of creating real-time plots than my cheap shared web hosting. (By using my own machine I will also be able to use GrADS-DODS, since my web hosting blocks port 9090.)<br>
<br>My plan is to purchase a "nettop" computer such as <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16883220072" target="_blank">this</a> or <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16883103297" target="_blank">this</a>; I'm looking for a bottom-of-the-line, energy efficient machine to run 24/7. I will be installing some variant of Linux on it.<br>

My question is: As far as GrADS and speed goes, what would be the best components to invest in? I'm no computer scientist, so I'm not sure if, for instance, purchasing an SSD hard drive would increase the speed more than extra RAM. (At the start, GrADS will be the only software running - maybe multiple instances at the same time, though.) I also found this message from Jennifer that stated that GrADS only runs on one processor; is this still true?<br>
<br></blockquote><div><br></div></div><div>Most of those smaller machines have a limit on the amount of memory it can take, so check the specs very carefully. The listed 2GB will get dated really soon. You can run multiple instances of grads with no problem (each one runs in 1 processor). However, they both must fit in memory and with 2GB you will be pushing it; make sure you can have at least 4GB; 8GB would be better. If you have a way of testing this now, check how much memory is taken by your typical grads process (on linux, use "top" to monitor memory consumption). Remember, running multiple instances only makes sense if you have multiple cores. </div>
<div><br></div><div>Having a SSD disk (lower capacity ones such as 64 GB are getting affordable) would greatly improve I/O (both for gridded data as well as for reading map database during plotting). Since your application is I/O bound, this could greatly improve performance. </div>
<div> </div><div>So the answer is both: buy enough memory to fit multiple instances of grads, a small SSD disk to hold the OS and gridded datasets.</div><div><br></div><div> Arlindo</div><div><br></div></div><font color="#888888">-- <br>
