Hi all,
I am quite new in the world of parallelization and I wonder if there is a

parallel computing is worthwhile you will be doing minutes of work on
each worker process and the startup time will not be signifcant.
thread considered and I use of computer with two 8 cores CPU and thus
showing a total of 32 threads in windows 7.
The first way to speed things up: use a decent OS: forking clusters is
much faster.
Currently, I use the default parameters (type = "PSOCK"), but is there any
fine tuning parameters that I can use to take advantage of this system ?
Thanks in advance for your help !
