Difference between JVM and HotSpot?
...ed from the imaginary instruction set to the actual instruction set of the CPU of the host machine. This can be done on-the-fly by an interpreter. Or the bytecode can be fully compiled and cached, to run faster than through the interpreter, in a process known as Just-In-Time (JIT) compiling.

NVIDIA vs AMD: GPGPU performance
... same value ($) cards.
In both cases, speeds were ~10x-30x comparing to a CPU.
I didn't test CUDA, but I doubt it could solve my random memory fetch problems magically. Nowadays, CUDA and OpenCL are more or less the same, and I see more future on OpenCL than on CUDA. The main reason is that Intel ...
Why are only a few video games written in Java? [closed]
... best with:
The biggest problem is that Java is really slow. On a pure cpu / memory / display / communications level, most modern cell phones should be considerably better gaming platforms than a Game Boy Advanced. With Java, on most phones you are left with about the CPU power of an original 4....

How do I measure time elapsed in Java? [duplicate]
...re; basically some implementations of nanoTime on some versions of OS/Java/CPU will use hardware CPU time stamp counter (TSC) . However this TSC may not be the same between cores/processors. If your thread is rescheduled to a different core partway through, you will end up with a start timestamp fro...

asynchronous vs non-blocking
...ng (you can say that most of time this loop does something nonsense but in CPU's eyes, X is running, which means that X is non-blocking) whereas X and Y are synchronous because X can't continue to do any other things(X can't jump out of the loop) until it gets the book from Y.
Normally in this case,...
