One easy way to speed this up is to use astatic const unsigned chararray as an ASCII lookup table, which maps a residue directly to its complement. This would replace the nest ofifstatements and probably give a nice little boost (and it appears it does, mak...
The function returns a scalar result from GPU to CPU The order of operations in the asynchronous functions is as in the figure below. The argument checking, calculation of process grid, and kernel launch take very little time. The asynchronous kernel running on the GPU does not block the CPU...
What does a member variable of class of boolean type will be intialised to by default in vc++? what does warning C4251 class needs to have dll interface to be used by clients of class mean? What exactly is the difference between TCHAR and wchar_t? What happened to io.h? What ...
The advantage of the call-back is that in the library API caller does not need to know about the callee function, it only knows the prototypes of the callee function. Let us see an example code where I am implementing the call-back function using the function pointer. ...
While C++ lags behind new languages for support at compile time, there is some ability to get some of the advantages. A simple case is to create a allow a runtime function that is simple enough to be run at compile time. This has the nice feature that if the function is not able to...
Function Naming Since NPP is a C API and therefore does not allow for function overloading for different data-types the NPP naming convention addresses the need to differentiate between different flavors of the same algorithm or primitive function but for various data types. This disambiguation...
int*sum=(int*)malloc(sizeof(int)); *sum=num1+num2; printf("%d\n",*sum); } printf("%d\n",*sum); return0; } In the C program above, themain()function uses a local scope to allocate an integer memory block to thesumpointer variable. Since we utilized thesumpointer to assign ...
The functions will likely use malloc and free behind the scenes but this does not necessarily have to remain this way. Finally, a number of operations on CPU set objects are defined: #define _GNU_SOURCE #include <sched.h> #define CPU_EQUAL(cpuset1, cpuset2) #define CPU_AND(destset,...
Allocator functions of the PyMem_Malloc() domain (PYMEM_DOMAIN_MEM) now use the pymalloc memory allocator instead of malloc() function of the C library. The pymalloc allocator is optimized for objects smaller or equal to 512 bytes with a short lifetime, and use malloc() for larger memory ...
While NGEN'ing your assemblies does not currently have a substantial impact (good or bad) on execution time, it can reduce total working set for shared assemblies that are loaded into many AppDomains and processes. (The OS can share one copy of the NGEN'd code across all clients; whereas ...
