Hello everyone, I have a question
In this simple example of KERNEL:
__kernel void blank(__global int4 *x) {
for(int i=0; i<25; i++) {
x *= 2;
}
}
I initialized a vector, and put in a buffer and send as parameter to KERNEL:
// Initialize data
for(i=0; i<100; i++) {
data = i;
}
If I am correct, the vector of 100 positions will be divided into 4 parts, within the variable '__global int4'. And how is the execution? will be created 4 work-items in the same workgroup and executed in a single processing unit. Or will be created four work-groups and each running on a different processing unit.
I did not understand how it will be executed in relation to work-item and work-group.
To send the KERNEL to run, I'm not using the "enqueueNDRangeKernel" function, just "queue.enqueueTask (kernel);"
Thank you
