Go up one level in this thread

Hi,

please don´t think that the speedup is 3.52 only becase the nps are getting up
by a factor of 3.52. In parallel search many "unnecessary" nodes are searched.
The amount of unnecessary nodes is dependant of the quality of the parallel
algorithm.

The speedup can only be calculated by looking at the time a program takes to
reach a certain search depth in different position. To test only one position
will not tell you anything.

Greetings Volker
