Re: [Help-gsl] random number sequence

[Sergey Mkrtchyan]

Steven, Frank huge thanks!

I did as Steven suggested and it worked smoothly, indeed I use script
to submit jobs to cluster and it was just a second to add the loop
parameter as an input for seed. I also played a bit with microseconds
which sounds like a good idea too :-)

I also tried not to use parameter given from the loop, but instead use
seed(rand()) function (anyways in 1000 runs, rand() won't show it's
badness I guess) but it didn't work. Now trying somehow to figure how
can I get random number in shell script to pass it to the program
argument instead of just parameter of the loop.

Thanks you very very much again!

Sergey
