Narrative:
Original clearance was to taxi to runway 34R at sea. Once we reached runway 34R at taxiway Q intersection, ground/tower cleared us to cross runway 34R cleared for takeoff runway 34L traffic on 8 mi final. We told tower it would be 30 seconds to reinitialize FMS and takeoff data. When the first officer pulled out our performance computer it had dumped our data. Tower told us to clear runway due to landing traffic, to exit taxiway P, left on taxiway C, hold short ILS critical area. He then said to expedite. When I made the turn off the runway I saw the air carrier Y B747 going around shortly after that tower told B747 to go around. 1000 ft vertical 800 ft horizontal separation (EST).

Title: MD11 CREW REQUIRED LENGTHY RECALCULATION TKOF DATA AFTER ACCEPTING A LAST MIN RWY CHANGE. THIS REQUIRED A LNDG B747 TO GAR AT SEA.
Narrative: ORIGINAL CLRNC WAS TO TAXI TO RWY 34R AT SEA. ONCE WE REACHED RWY 34R AT TXWY Q INTXN, GND/TWR CLRED US TO CROSS RWY 34R CLRED FOR TKOF RWY 34L TFC ON 8 MI FINAL. WE TOLD TWR IT WOULD BE 30 SECONDS TO REINITIALIZE FMS AND TKOF DATA. WHEN THE FO PULLED OUT OUR PERFORMANCE COMPUTER IT HAD DUMPED OUR DATA. TWR TOLD US TO CLR RWY DUE TO LNDG TFC, TO EXIT TXWY P, L ON TXWY C, HOLD SHORT ILS CRITICAL AREA. HE THEN SAID TO EXPEDITE. WHEN I MADE THE TURN OFF THE RWY I SAW THE ACR Y B747 GOING AROUND SHORTLY AFTER THAT TWR TOLD B747 TO GO AROUND. 1000 FT VERT 800 FT HORIZ SEPARATION (EST).
