How do CUDA blocks/warps/threads map onto CUDA cores?
I have been using CUDA for a few weeks, but I have some doubts about the allocation of blocks/warps/thread.
I am studying the architecture from a didactic point of view (university project), so reaching peak performance is not my concern.

Why does sun.misc.Unsafe exist, and how can it be used in the real world?
...e-and-swap
The sun.misc.Unsafe functionality of the host VM can be used to allocate uninitialized objects and then interpret the constructor invocation as any other method call.
One can track the data from the native address.It is possible to retrieve an
object’s memory address using the java.lang...

What is “overhead”?
...
Re data structure memory overhead: With most memory allocators, it's even worse than that. Each value returned by malloc has a built-in overhead of 8 bytes due to the allocator (assuming classic 32-bit machine) consisting of the size of the block plus guard values. And that's ...
How to convert wstring into string?
... The above code gives (as copied) gives me a *** glibc detected *** test: malloc(): smallbin double linked list corrupted: 0x000000000180ea30 *** on linux 64-bit (gcc 4.7.3). Anybody else experiencing this?

What does the explicit keyword mean?
...se, you have a class String:
class String {
public:
String(int n); // allocate n bytes to the String object
String(const char *p); // initializes object with char *p

Now, if you try:
String mystring = 'x';
The character 'x' will be implicitly converted to int and then the String(int...

How can I efficiently select a Standard Library container in C++11?
...expensive in terms of performance (each newly inserted item costs a memory allocation), but it is consistent. It also offers the occasionally indispensable ability to shuffle items around for virtually no performance cost, as well as to trade items with other std::list containers of the same type at...
How do I pass a unique_ptr argument to a constructor or a function?
...d for the question as to why it is exception-safe (if during the recursive allocation process memory runs out and some call of new throws std::bad_alloc, then at that time a pointer to the partly constructed list is held anonymously in a temporary of type list created for the initialiser list, and i...
Does using final for variables in Java improve garbage collection?
...to a "young generation" and an "old generation". All objects are initially allocated in the young generation (sometimes referred to as "the nursery"). Since most objects are short-lived, the GC is more aggressive about freeing recent garbage from the young generation. If an object survives a collect...
