It depends on your sieving software:

If you are using sr1sieve, you can run different intervals [pmin-pmax] on the individual machines. All you have to do is to collect the factors found (using the "-f" switch).
For example:

Code:
./sr1sieve -i input.txt -o output.txt -f factors.txt -p 1000000 -P 2000000
After a while you transfer the factors files to your master machine and update the sieve file using srfile, which is part of srsieve:

Code:
./srfile -g --known-factors factors.txt sievefile.txt
(The "-g" switch is to force the NewPGen file format.)

There might also be a similar procedure for NewPGen, but I haven't tried yet...
