I have come across the term ‘grid node’ many times but so far I have not had the opportunity to ask someone what it is all about. Could you kindly explain what a grid node is in High Performance Computing? How does a grid node work and how do I streamline operations to perform efficiently at the nodes?

Have you used IBM’s world community grid facility before? How did you find it? How did it benefit you in any way? In which ways did using this community profit you? Would you recommend this facility to people who use supercomputers? What are the requirements for membership of this community?

I want somebody with firsthand experience of using Windows Groove file sharing system. How did you find this particular system?

Please I need a quick tutorial on how to use Dropbox facility online. I would like to know if you have used Dropbox before and how useful you found it. What particular areas or tasks would you recommend someone use Dropbox? What main issues have you found with Dropbox? Are there any glaring security issues that may have to be considered by the prospective user?
