[gate-users] Random seed initialization

[Capit Nicolas]

Hello,

I want to start a large amount of Gate jobs on a cluster and it is necessary to change the random seed for each job (otherwise I will obtain the same result for each of them).

I tried to use the command "/random/resetEngineFrom" but there is (in all case) a running error : 

 *** Break *** segmentation violation
Generating stack trace...
j97 = 1089915644, u[j97] = Abort 

Is this a bug or I don't use this command correctly?
Is there an other method to change the random seed?

Thank you for your help.
