I'll be interested to see how the categoriser handles "bioinformatics" :)</p> <br class="clear" /> Thu, 05 Jun 2008 23:07:34 -0400 Neil comment 4464 at http://www.nodalpoint.org http://www.nodalpoint.org/2008/05/10/eureka_science_news_intelligent_science_news_aggregator#comment-4461 <blockquote><p>I'm a microarray analyst, so I used the same techniques I use to cluster genes, but this time to cluster news! </p></blockquote> <p>So cool!! :)<br /> Congratulations. What kind of approach have you used to cluster those news?</p> <br class="clear" /> Thu, 05 Jun 2008 04:57:29 -0400 dalloliogm comment 4461 at http://www.nodalpoint.org http://www.nodalpoint.org/2006/03/30/outsourcing_computation_clusters#comment-2968 <blockquote><p> As anybody who's built or administrated a computational cluster can attest, there are some serious advantages towards outsourcing compute center needs </p></blockquote> <p>I'm still recovering from building and administrating a compute cluster. It was so bad, I had to leave the state.</p> <p>I guess for very large clusters (10s or 100s of nodes), there are definite advantages to outsourcing in terms of power and cooling costs. I don't necessarily agree that this leads to more enterprise-type software and less scripting. What cluster administrators need to realise is that a cluster for biological applications is quite different to a cluster for more traditional HPC research such as physics or engineering, where people tend to write their own parallelised code for MPI or whatever. Biological apps by their nature involve glue scripts to generate data analysis pipelines. We also require local database storage with automated incremental updates and efficient distribution to nodes.</p> <p>What it boils down to is: make friends with the admins on an outsourced cluster and explain your needs or work in an environment where others share your "can do" attitude, so as you get it done. Many academic environments are a nightmare when it comes to this kind of endeavour, not because it's hard but because they lack IT staff with sufficient understanding and because of stifling beaurocracy, restrictions, rules and regulations surrounding simple tasks such as buying and installing an air conditioner.</p> <br class="clear" /> Thu, 30 Mar 2006 08:09:21 -0500 Neil comment 2968 at http://www.nodalpoint.org
