In total, the particle system runs almost twice as fast as initially! Read more to see what pieces of code were changed.

For the TL;DR crowd: In one of the Tasks [1] of a European Space Agency project that I am working on, I ported IDL code to C++/CUDA - achieving a 35x speedup. The code is on GitHub, and in this blog post I reproduce the main points of the deliverable I wrote, explaining the optimizations I used to get the performance levels we needed (cache-related optimizations, SSE, OpenMP, CUDA, etc).

See how well you know (or can anticipate) gcc's optimizer. For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization. Will gcc apply that optimization? Put another way, will the code on the left be as fast as the code on the right, when compiled with an optimizing gcc?

In the previous blog-post I promised to tell you why it is difficult to demonstrate 64-bit errors by simple examples. We spoke about operator[] and I told that in simple cases even incorrect code might work. Here is such an example:

When loading JavaScript from a third party, do it asynchronously.
