The solution I was looking for is the one you suggested. You know I already had tried ParallelTable but some how it didn't work at the time. Then I just noticed in your code that you don't end this line {a Pi/10, res} with a semicolon. If you did end it with a semicolon you wouldn't have the results from all kernels as a table assigned to allresults, but Null. You simply define the return value of every loop, and Table does the rest. :) Well It worked, thanx again. Sincerely, Nasuf
