Passing arguments through __local memory in OpenCL -


i confused the __local memory in opencl here. read spec saying data flow has host __global, , __local. see kernel function this:

__kernel void foo(__local float * a)

i wondering how data transferred directly __local memory in way?

thanks.

it not possible fill local buffer on host side. therefore have follow flow host -> __global -> __local.

local buffer can either created on host side , passed kernel parameter or on gpu side inside kernel. creating local buffer on host side gives advantage decide size before kernel run can important if local buffer size needs different each time kernel run.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
