Mine the Harvest

A couple weeks back I posted about Firestats. I really have been amazed by this little gem. I love seeing all the countries people come from, what blog and wiki articles they read, what the most popular pages are, etc. It is like geek candy.

I was surprised at the amount of traffic I am getting and the Google rankings some of my wiki pages have – they are surprisingly good.

So, I decided to add some additional features to my blog and wiki.

You will now see an AddThis widget at the end of each post. This has a menu popup  allowing you to perform a number of social bookmarking functions – you can Digg a post, or add it to a number of social sites.

I have also made it so any blog post that gets Dugg will have a Digg Badge show at the top of the post.

If you want to do the same, I wrote a wiki article that might help  you. I am hoping to see some of these pretty soon:

I am still working out the kinks on using the AddThis widget in MediaWiki, I have the plugin showing up correctly, but can’t seem to get a pop up style button to work, and need to see if the one I have is really working, etc. I would love to get this working fully on my wiki. I don’t see wiki articles Dugg very much, and think this could be pretty cool.

If you read a post or article you like, I would love it if you would use the widget at the end to link it to your favoriate social bookmarking site, Digg or otherwise. And comments are of course always welcome. I see lots of pople reading articles but not many comments, so I would like to do more to encourage this.

Thanks, and as I learn more I will share what I discover here on on my wiki.

I’ve been using a stats plugin for Worpress and it has done a good enough job, but I recently found myself looking for a stats reporting plugin for my Wiki as well. I have added a lot of articles over the last year and was curious to see exactly how many hits it gets.

Googling around quickly led me to Firestats. What a wonderful product. It allows you to centrally managed stats from several applications such as MediaWiki, WordPress, Joomla, Drupal, etc. and manage multiple instances of these very easily. See their page on multiple sites for more information. Additionally you can use this on any generic PHP page, which is a great feature.

The stand alone installer worked extremely well. After Firestats is installed you can follow the directions on how to add a database and then use the plugins for a variety of applications. Follow the instructions for these plugins very carefully and before you know it you will have stats pages for all your separate sites you wish to monitor.

The Firestats interface is quite nice, with graphical representations for visitors browser types, OSes, country flags for their origin IP, etc. The interface is quite nice.

Here are a few screen shots, but it really is far more impressive that these show. This one shows the hits page, with icons for the visitors browers, OS and country along with the Goolge or other referring link. Very geeky undoubtedly.

This one shows the categories of browsers and versions. There are also categories for OS versions and countries too:

If you are looking for stats software for you site, I would highly recommend this. It seems quite versitle. I am going to look into and see if there are extended graphing and reporting capabilities, but all the data is just stored in a MySQL database, so you can easily do with it as you will.

My company, Sago Networks, is launching a new section to our website – Sago Labs. I’ll be contributing to this via my blog and posting interesting bits on what behind the scenes projects I am involved with to let others know some of the interesting things we have cooking in the kitchen and sharing this with the community.

Here you will find information on ongoing research projects and results, new technologies we are exploring, and general Geekness in the Superlative. Also, you may get a comment or two on Sago culture, people and events – as it is a rather colorful place to work and there is always something interesting or funny afoot.

Watch the RSS feed for more to come!

Hot on the heels of the last post on the Intel C Compiler for Linux, a colleague pointed out this MySQL developer post which talks about compiling MYSQL with different options and compilers to obtain performance improvements.

I Googled around, thinking that perhaps there may be some information from people who have specifically tried to compile the  MySQL daemon with the Intel Compiler (ICC). Indeed I found quite a bit. Here is an extremely interesting presentation giving MySQLd benchmarks from compiling with ICC. Although this is based on earlier versions of ICC and MySQL, it is quite likely similar performance benefits could be seen with current versions.

Further looking about I discovered that MySQL binaries compiled using ICC for a variety of platforms are available for download directly from the MySQL Developer site. Just look in the downloads section and you will see the ICC versions available.

This makes it extremely simple to expiriment with these versions and benchmark them to see if they may be useful in a production environment.

Atom Inside

Recently I learned that Intel makes its professional C compiler for Linux available for free. I discovered this fact at this blog, the writer of which extolled the virtues of the Intel C Compiler (ICC) and how the binaries it creates can run faster than those compiled with the GNU C compiler (GCC) – up to 35% faster. The author gave some test results of benchmarks created using Crafty, a chess engine.

Well – all this seemed pretty interesting to me! Using Crafty seemed a great idea, chess engines being so computationally intensive. Crafty also has an apparently undocumented benchmark function, so this is perfect.

Of course I am familiar that different compilers, compiling options and optimizations can effect the performance of the resulting binary, but I have never personally compared these results. And the potential for such significant gains was too tempting to pass up. Plus I could experiment with the Atom specific optimization flag. A veritable candy store of geekness.

I decided to duplicate that authors test, using the Intel and GNU compilers to compile Crafty and generate some benchmarks. My results were quite comparable to his, in fact the ICCC benchmarks were a bit better.

Here you can see the comparison between the GCC and ICC versions, and well as a third option showing an ICC version compiled with the -xL optimization flag for the Intel Atom.

In Crafty there was a slight improvement compiling with the -xL flag specifically for the Atom architecture. However, there is a significant difference between the ICC and GCC versions as you can see:

Compiler Comparison

The substantial improvements available through compiling using the Intel C compiler clearly show it should be used when possible, particularly on computationally intensive applications.

Installing ICC is quite straightforward. Ensure you have GCC and G++ (called GCC-C++ in some distro packages) as these are required. Then just run the install script.

The specific Makefile options I used to compile each of the above three versions can be found on this Wiki article I wrote on Crafty – I did have to experiment with these a bit to get the ICC version to compile correctly. I also have a page on the Intel Compiler specifically here.

Have fun test driving this for yourself and please comment your tests and findings, I would love to hear about them.
