Though they are not called out explicitly, each module is supported by a series of hands-on lab projects that cover the most frequently used functions of each library or tool.

BGM course outline


The second two days of the HPC workshop are designed for anyone writing, debugging
or optimizing parallel applications or for someone in the reseller channel who has
customers who will be doing so. It begins with a module on the effect
ive design of a
parallel application. We build on that by covering the Intel compilers and libraries that
are most frequently encountered in the HPC environment. The workshop next covers the
debugging of a parallel program using one of the most popular d
ebuggers
–

Totalview
from Etnus. Finally we cover the optimization of the parallel program using the Intel
Trace Collector and the Intel Trace Analyzer.
Though they are not called out explicitly,
each module is supported by a series of hands

frequently used functions of each library or tool.
