Guess: omit the :2 and list dual-cpu machine twice:

1:linux4gb
1:linux4gb
1:linux3gb
1:linux3gb
1:linux2gb
1:linux2gb
1:linux1gb
1:linux1gb
granularity:1



 

Good guess!  The lines in your .machines-file correspond to jobs, not to machines.  So for each line, a job will be started, with the weight specified at the beginning of the line, and the number of processors specified at the end of the line (1 by default).

1:a:2  means : start a job with weight 1 on machine a using two processors of machine a

while

1:a:1
1:a:1

means : start a job using one processor of machine a, then start another job using one processor of machine a.

 

which is what you want.

 

Kevin.
