HISTORY
ColdFusion (2021 release): Introduced the following parameters:
- parallel
- maxThreadCount
syntax
arrayMin(array [, parallel] [, maxThreadCount]) |
Parameters
|
|
Description |
|
array |
Name of an array |
|
parallel |
True if you want to enable parallel programming. |
|
maxThreadCount |
The number of threads the function can execute. The number of threads must be between 1-50. If the value exceeds 50, there is an exception. |
Example
<cfscript>
myArray=[23,76,1,-43,9,112]
minVal=ArrayMin(myArray)
WriteOutput(minVal)// Returns -43
</cfscript>
Using parallelization
<cfscript>
for(i=1;i<=1001;i++){
arr[i] = i*2;
if(i == 554)
arr[i]= -2147483648
}
//writedump(arr)
//writeoutput(arr.min())
t_start=GetTickCount()
writeoutput(arraymin(arr,true,5))
t_end=GetTickCount()
writeoutput("<br>Time taken with 5 threads:" & t_end-t_start)
t_start=GetTickCount()
writeoutput(arr.min(true,10))
t_end=GetTickCount()
writeoutput("<br>Time taken with 10 threads:" & t_end-t_start)
t_start=GetTickCount()
writeoutput(arraymin(array=arr,parallel=true,maxthreadcount=20))
t_end=GetTickCount()
writeoutput("<br>Time taken with 20 threads:" & t_end-t_start)
t_start=GetTickCount()
writeoutput(arr.min())
t_end=GetTickCount()
writeoutput("<br>Time taken with no parallel:" & t_end-t_start)
</cfscript>
