The actual problem was the usage of the variable ‘counter’ by second thread when the first thread was using or about to use it. In other words we can say that lack of synchronization between the threads while using the shared resource ‘counter’ caused the problems or in one word we c...
For get/set of an int, anything that can be wrapped in astd::atomic<>, a mutex is not required. Just make it astd::atomic<int> http://en.cppreference.com/w/cpp/atomic/atomic For more complex resources, one could use a mutex to serialize access. The typical usage should be one mut...

Hello to everyone i am developing an application with two processor, one is using pure C code and the other one has an uCLinux running in it. I want them to share the same onchip memory so they can comunicate with each other, i've done with no mutex and it works fine as long ...
Let’s see the member function which is available in Mutex see below; lock:We can use this member function to lock the object which we want to use. This object would be our shared resource which we do not want to be accessed by the mutex threads to prevent data consistency. ...

One could solve this issue by surrounding the counter += 1 line with mutex locking/unlocking functions or semaphore actions, but in this case, we just declare counter as the type of atomic_int. This integer object now is said to have atomic property, implying that any access to it will ...
Read the arguments to VirtualAlloc() in the question again: the two allocations use two different ranges of pages. I'm having a similar problem, where code that walks the virtual space calling VirtualAlloc() with specific base addresses fails to find *any* allocatable space within a 1 GB ...

I installed the package with conda. Should I change “import torch” to “import pytorch” in the information you provided? import torch print(torch.cuda.get_device_name(0)) # Should print the name of your GPU print(torch.cuda.is_available()) # Should return True if PyTorch can use the...
