You use pointers. Specifically, you use a pointer to an address, and using a standard c library function calls, you ask the operating system to expand the heap to allow you to store what you need to. Now, it might refuse, which you will need to handle. The next question becomes – how do you … Read more
In C arguments are passed by values. For example if you have an integer varaible in main and the following function then if you call the function in main like this then the parameter gets the value of variable x in main. However the parameter itself occupies a different extent in memory than the argument. So any … Read more
As a general rule (i.e. in vanilla kernels), fork/clone failures with ENOMEM occur specifically because of either an honest to God out-of-memory condition (dup_mm, dup_task_struct, alloc_pid, mpol_dup, mm_init etc. croak), or because security_vm_enough_memory_mm failed you while enforcing the overcommit policy. Start by checking the vmsize of the process that failed to fork, at the time of the fork attempt, and then compare to the amount of free memory (physical and swap) as it … Read more
The view function is meant to reshape the tensor. Say you have a tensor a is a tensor that has 16 elements from 1 to 16(included). If you want to reshape this tensor to make it a 4 x 4 tensor then you can use Now a will be a 4 x 4 tensor. Note that after the reshape the total number of … Read more
%reset seems to clear defined variables.
This happens when the pointer passed to free() is not valid or has been modified somehow. I don’t really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It’s not always easy to spot what the problem is for a novice in their own code … Read more
%reset seems to clear defined variables.
According to Python Official Documentation, you can explicitly invoke the Garbage Collector to release unreferenced memory with gc.collect(). Example: You should do that after marking what you want to discard using del:
I am programming in C++ and I am always wondering what exactly is stack memory vs heap memory. All I know is when I call new, I would get memory from heap. If if create local variables, I would get memory from stack. After some research on internet, the most common answer is stack memory … Read more
