On the sandbox page, you will find links to several "scripted, hands on exercises" (under the heading "Optimize server performance and programmer productivity with IBM compilers"). They're a little hard to find in all the clutter, so here's a list of them, with a brief description of each:
performance with new XL C/C++ and Fortran compilers: Why you want
to install the latest version of the compiler - it's even faster (if
auto-vectorization: Some Power architectures have vector (SIMD)
hardware built in - make the best use of it by learning what option
settings are best
uninitialized floating point and integer variables: A common error
for beginner and professional alike is to forget to initialise
variables. Let the compiler help you find these mistakes!
of IBM XL Fortran, IBM XL C/C++, and Java: How the Fortran compiler
can make friends with C/C++ and Java, allowing you to use the
scientific and mathematical power of Fortran while interfacing with C
and taking advantage of the powerful GUI available from Java (or linking
it to a web server). This is my favourite of the four, but it's my
work, so I'm biased.
