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

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