By Master / slave problems, how to set up on how many threads to be started at the slave side ? I have already experimented with putting: evalthreads = 3 breedthreads = 3 , in different .params files at the slave side, but nothing worked so far. Only one thread is by default running at the slave side, and I can not change this. Any suggestion in which .params files or how to setup this? Thanks in advance. Nikola
