The performance improvements due to parallel computing hardware (think Metal GPUs and their successors) will be so insane in 16 years that your current laptop won't stand a chance at doing anything what will be considered standard then.
- lmm 6y agoIncreasing parallelism is irrelevant for most workloads due to Amdahl's law.
- auggierose 6y agoThat's bullshit. All of the programs I have written recently had an incredible speedup after porting relevant parts of the program from single-threaded to GPU. Right now we are hitting the threshold of incompetent programmers and tools long before any other.
- Filligree 6y agoAmdahl's law is only relevant if you can't change your algorithms. If you can, then most of the time it's a non-issue. The human brain runs off umptillion neurons each running at 100-1000 Hz (depending on measure). Not GHz, MHz or even kHz. Hz. Obviously it's an extreme case, but if general intelligence can be achieved without fast serial computing then there should be lots of things we can do with a few dozen cores all running at GHz rates.
