I tested the functions on two dual core machines. I had great gain when paralellizing processing between the processors of dual core machine or between the two machines using a single processor in each. However, I had no significant gain when trying to using both processors on both machines. Is that because the gain of using more processors is being reduced by increased load of data recording when you add more processors/machines? Also, there are times when I get an error in which one of the workers can't delete the temporary files and this seems to happen more frequently when you increase the number of workers. Is anyone having the same issues? My two machines run Vista 64bits.
