Reply to comment by Pocok5 in ELI5: Whats does compute credits in Google Colab actually do to the code running speed as opposed to normal free Colab by blry2468

Yes, except my for loops use the number of times it is looped and the loop step as variables, so it does not repeat the same operation over and over again cause it changes each time it loops by abit. So thats the issue.

If it's just that then it's no issue, in fact it is integral to how CUDA works (I'm assuming loop step is constant over one run of a loop). You get the index of the current thread and you can use it - for example the CUDA prime check example is "check the first N integers for primes" -> start N threads and do a prime check algorithm on the thread index. The only problem happens if your loop #n+1 uses data calculated during the #n loop.
