QT concurrency - data parallelism

Message 1 in thread

Hello,

i have a question because i am not sure if i have the right opinion:
is it right that the Qt Concurrency-framework does not support data 
parallelism?
with data parallelism i  mean a parallel-loop that does the same 
operation on different data.
like a parallelisation fo the following for example:
int array[100];
int i;

for(i = 0; i < 100 ; i++){
array[i] = 0; 
}

thanks.

greetings, peter

Have a look at the fine docs:
http://doc.trolltech.com/main-snapshot/threads.html#qtconcurrent

there is no "parallel for", but QtConcurrent::map is very similar.

Cheers,
Peter
