Fabanclient request arrival process question in cloudsuite 3.0

[Guangyan Hu]

Hi,

I'm a user of the cloudsuite 3.0 web serving benchmark. I'm trying to 
change the request arrival process to be negative exponential so I just 
uncommented the @NegativeExponential block in Web20Driver.java like this:

@NegativeExponential(cycleDeviation = 2,
                        cycleMean = 4000, // 4 seconds
                        cycleType = CycleType.THINKTIME)



/*@Uniform(cycleMax = 120000,
         cycleMin = 40000,
         cycleDeviation = 10,
         cycleType = CycleType.THINKTIME)*/


/*@FixedTime(cycleTime = 10000,
    cycleType = CycleType.THINKTIME, cycleDeviation = 1000)*/

However, I got a compilation error when I try to compile it:

" [javac] /web20_benchmark/src/workload/driver/Web20Driver.java:96: 
error: cannot find symbol
    [javac] @NegativeExponential(cycleDeviation = 2,
    [javac]  ^
    [javac]   symbol: class NegativeExponential
    [javac] 1 error
"


Is this the correct to way to change the request arrival distribution?



Thank you and best regards,
Guangyan
