Threads in IDL 7.0 [message #63120]

Hi,

I have have read the Chapter "Multithreading in IDL" in the IDL-Help. As
far as I can see some IDL functions use threads.

Basically I want to count elements of a big array that exceed a given
number.

count=0
for i = 0, 200000 do begin
if array[i] ge 10. then count++
endfor

On my dual-core computer top shows a CPU-load of about 50%. So I guess
IDL handles this problem single-threaded.

Is there a simple way to split the task. Something like

;Thread 1
count1=0
for i = 0, 100000 do begin
if array[i] ge 10. then count1++
endfor

;Thread 2
count2=0
for i = 100001, 200000 do begin
if array[i] ge 10. then count2++
endfor

count = count1 + count2

Regards

Bernhard
