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>
