15 AFAIK theres a ENV-Variable or Makefile option (dunno what or where exactly this has to be specified) to
16 say "make" to be more parallelisized, for optimum of "n" CPUs, maybe there is an actual speed increase, if one sets
17 this value to the amount of computers in the cluster, but i dunno how to set this for for example kernel compilation or ebuilds.

19 does anyone have experience in this and can say me how to set this cpu number and if it is useful with openmosix?
