Narrative:

Advised tower 'ready for departure request runway 34L.' tower said 'approved.' tower requested 'say direction of flight.' I requested a left crosswind departure and was cleared for takeoff. Prior to entering the active I turned on transponder, strobe lights, recognition lights, and landing lights. Started takeoff roll on runway 34L. Approaching rotation speed tower cleared a cessna citation into position and hold on runway 16R. Citation was on runway as I broke ground. Tower controller requested that I offset to the right for traffic on the runway. Loss of separation due to controller clearing to aircraft on to runway with opposite departure directions. My aircraft was directly in front of the tower with all external lights on when citation was cleared onto runway. Controller was working 2 frequencys and was distracted.
