Java JIT compiler optimizations - is JIT consistent in respect to volatile variables value caching?

问题 I'm trying to better understand how does the JIT compiler work for java in respect to volatile variable value caching. Consider the example presented in this question: Infinite loop problem with while loop and threading: boolean loaded = false; // not volatile!!! private boolean loadAsset() { new Thread(new Runnable() { @Override public void run() { // Do something loaded = true; } }).start(); while (!loaded) { System.out.println("Not Loaded"); } System.out.println("Loaded"); return false; }

Bounds checking is not supported for CUDA

问题 I am trying to use Numba and access the GPU in order to accelerate the code, but I get the following error: in jit raise NotImplementedError("bounds checking is not supported for CUDA") NotImplementedError: bounds checking is not supported for CUDA I saw that another question was raised, but not completely specified nor answered here. I implemented the 2-for loops when I saw that the vectorized code ( y = corr*x + np.sqrt(1.-corr**2)*z ) did not work (same error). I also tried to play around

问题 I have a simple function to rank poker hands (the hands are strings). I call it with rA,rB = rank(a),rank(b) and here is my implementation. Works well without @jit(nopython=True), but with it, it fails: File "C:/Users/avi_na/Desktop/poker.py", line 190, in <module> rA,rB = rank(a),rank(b) File "C:\Continuum\anaconda3\lib\site-packages\numba\dispatcher.py", line 344, in _compile_for_args reraise(type(e), e, None) File "C:\Continuum\anaconda3\lib\site-packages\numba\six.py", line 658, in

Can you dynamically compile and link/load C code into a C program?

问题 I read about eval in C, and it makes sense that if you write a C string parser/evaluator, you can just map it to specific functions in your main C program. But it doesn't actually place it into executable memory from what I understand, like a JIT compiler seems to do. I don't fully understand JIT compilers (I never made one) but I get the gist. So what I'm wondering is if you can create sort of a JIT compiler in C without doing too much work of parsing C strings and converting to ASTs and
