Hi I'm running the same R script (throuth linux shell) of several cpu's. This R program uses random numbers and the result should be different every time. But if put jobs (through Torque) for several cpu's I get the same result. As a resealt my program saves numbers in file with randomly generated names. works like a charm on one cpu, but I get the same result from different cpu's. So my question is, how can I resolve this? How to set pseudo random number seed so that different cpu's would produce different results? Thank you...
