OpenCL in Android

I have worked on OpenCL in Android for two monthes.
there are several things, you need to care about.

after compile, if your program stops at clCreateProgramWithSource, then your Kernel code has problem to build. you need to fix it.
several things I realized are,
1. You need to initialize array in Kernel like
    int array[10]; // == illegal.
    int array[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; // == legal.
    but I would not use array in Kernel code. cause local memory issue.
2. There should not be unused arguments or value.
3. ..( I will write down more, when I remember lolz)

and also if your program dies at clRead,, something, which means during running kernel code,
then think about GPU or CPU hanging, OpenCL use almost most of processors, so when other program try to use GPU or CPU, Hanging will be happened, so
"YOUR KERNEL CODE SHOULD BE SIMPLE AS HELL"
I have tried some read_imagef func 2500 times ( It was for loops 10 * 10 * 5 * 5) it... of course die.
cause it will run 2500 times for each pixel.

well those are I have learned so far.. :)

function in .bashrc

There are bunch of thing you can do with bash.

This one is easiest and I use it more than a lot..

Which is Function in bash!


mygrep() { grep -RHni --exclude=.git --exclude=svn "$@" . 2> /dev/null; }

So this is basically using grep with your argument.

when you trying to find "hello" in your folder

you type "grep -RHn hello . 2> /dev/null" something like this.

with mygrep function

you can only type "mygrep hello" well that's it.

cause mygrep redirect to mygrep function in bash :)
