I wish Intel would make their compiler free, or work harder on integrating their optimizations into free compilers. They can't be making much money off it, and it just feels counterproductive to charge customers extra to get the best performance from their own hardware.
- chrisseaton 9y agoMaybe their optimisations reveal proprietary information about how their processors are implemented that they don't want to disclose?
- peatmoss 9y agoMaybe people would flip the RUN_SLOW_ON_AMD flag to false. :-)
- sanxiyn 9y agoAnecdotally, changes to ICC are evaluated (by management) on two metrics: improvement on Intel CPU, but also improvement on Intel CPU minus improvement on AMD CPU. The end result is similar to RUN_SLOW_ON_AMD flag. If you think this cheesy, consider this: you are a manager of Intel compiler team. Someone implemented an optimization that improves performance by 1% on Intel, but 10% on AMD. Do you think it is a good change? The change will be no-brainer on GCC, but consideration for ICC is necessarily different.
