Matrix Multiplication, Performance, and Scalability in OpenMP: Student Challenge

This year, a simple matrix multiplication problem was posed to the students and we set up an internal contest, to obtain the fastest serial code. Many versions were submitted, and we finally obtained 20x of improvement over the most naïve implementation. The students learned a lot about compiler optimizations, and above all, the effect of the caches in the performance of the code.

Using X on the Intel® Manycore Testing Lab

Using X services on the Intel(R) Manycore Testing Lab is unsupported, yet possible. This article demonstrates in general and in detail the four necessary steps to run X on the server:

1) Make a standard, character-based connection
2) Run the required software on the server
3) Run your secure PCX server software
4) Make the connection

Two secure PCX server solutions are discussed.
