Cheap Supercomputer

A supercomputer was built in a Japanese university it costed only USD $420.000, a very cheap price for this type of systems. It is based mainly in GPU which has more cores than traditional CPU and that allow users to run parallel applications.

This can also be done in a lower scale, so you can build your own parallel pc installing a high end graphic card and then learning how to program it. The framework of development depends on the type of graphic card, for Nvidia you can use cuda and for AMD(ATI) you can useá OpenCL(which can also be used in a Nvidia Card). If you keep looking at this topic, you’ll find that this isn’t easy but it worthwhile.

Now I give you a couple of videos, the first is about the Japanese supercomputer and the second shows a simulation using CPU, Cuda and OpenCL.

  2. Temporary Accomodation
    Vancouver is a touristic destination, so it has a lot of hotels and hostels. It is a good option to stay in temporal place at the beginning of your trip in order to select the best alternatives for a long term accomodation.
