Hi Mohammad and all others,

Thanks for your clear answer, Mohammad. I just wonder what the probability is that two (or more) jobs will start a DPM event with the same seed. Twisted Evil

The "time(NULL)" instruction gives an output in precision of seconds, right? Hmmm, in that case it could actually be very likely. It might, therefore, be more safe to set it up it via gRandom, which one can more easily control from the "outside". Actually, is this the same for the box generator (as used for the other DC macros)?

Best wishes,

Johan

(ps, really nice work what has been done for this DC. Thanks to everyone involved, really impressive!!!!!)
