Beowolf Clusters: Cheap supercomputers for poorer pockets
The demand for faster calculations can’t be met by only relying on the speed increase resulting from advances in computer technology as high end super computers are that much costly. One of the solutions to this problem for ‘not-so-deep-pockets’ is the distribution of the numerical tasks to a set of machines. So how to provide supercomputer capabilities cheaply? The answer is Beowolf Clusters. This process is called parallelization because the computers complete their tasks in parallel instead of the traditional step‐by‐step (serial) execution. As computer codes have been updated to use this new paradigm, the demand for parallel computers has grown. In general, such computers need to have: Continue reading “Beowolf Clusters: Cheap supercomputers for poorer pockets”

How to price internet services
The Internet is a world-wide network of computer networks that use a common communications protocol, TCP/IP (Transmission Control Protocol/Internet Protocol). TCP/IP provides a common language for inter operation between networks that use a variety of local protocols. To support such a system, two costs are involved. One is to maintain the routing table, to specify the path that information packets need to travel, to reach from the source to the destination. Keeping these tables organized and up-to-date is not a trivial task. Second issue facing the internet usage is the speed of service that is to be provided, and at what price should such a service be charged. Continue reading “How to price internet services”
