Coldwater Vision Center was plagued by an aging phone system and an unreliable network. When the network went down, staff couldn’t access patient records or file insurance claims. Like many small businesses, Coldwater Vision’s network had grown organically with devices from various vendors added piecemeal over time. The solution? An end-to-end integrated Cisco solution, which improved productivity and staff morale.
The pace of IT and data is moving exponentially. With a rapidly growing networks across all industries, keeping track of all these connection points will give rise to a new business leader: The Chief Information Officer, or CIO.
Why will a CIO be such a crucial part of future business? Read More »
MPI implementations are large, complex beasts. By definition, they span many different layers ranging from the user-level implementation all the way down to sending 1s and 0s across a physical network medium.
However, not all MPI implementations actually “own” the code at every level. Consider: a TCP-based MPI implementation only “owns” the user-level middleware. It cannot see or change anything in the TCP stack (or below). Such an implementation is limited to optimizations at the user space level.
That being said, there certainly are many optimizations possible at the user level. In fact, user space is probably where the largest number of optimizations are typically possible. Indeed, nothing can save your MPI_BCAST performance if you’re using a lousy broadcast algorithm.
However, lower-layer optimizations are just as important, and can deliver many things that simply cannot be effected from user space.
Everybody is looking for ways to increase efficiency and trim expenses nowadays. Your company’s channel partner is no exception.
With that objective in mind, most partners have adopted a support model through which they remotely access computers and other devices on your network when those devices need service, or in some cases merely threatening to need service. Doing it this way eliminates the need for trained personnel to climb into a truck, sit at numerous red lights, spill their coffee, and then repeat the process in the opposite direction after fixing whatever part of your IT infrastructure was green-about-the-gills.
I’ve been working on a future-oriented economic growth program with the US Conference of Mayors and we have identified Chattanooga as a location to demonstrate some of these ideas because it has, by far, the largest and fastest deployment of fiber in any metro area in the US — enabling every home and other building to have a gigabit connection.
