I guess it’s time once and for all to explain the reasons why I think OpenMP is the future of parallel programming, at least in the short term. I will start with the short version:
relatively high level of abstraction
performance
maturity
We have a dual-processor, dual-core Opteron system at work (that makes 4 cores in total ). I often use it for performance-measurements of my parallel codes. I expected performance variations in my benchmarks when only two threads are used. The explanation of course would be simple: the Opteron-system is actually a NUMA-system. Half [...]
To explain a little more about the intentions of this blog, I will try to make it clear in this article, why parallel programming is a great thing to do and why I love doing it.
When I first started with parallel programming while at the university, I mainly did it because it was a challenge. [...]
