Abstract
One of the key science projects of the Square Kilometer Array (SKA) SKA is to provide a strong-field test of gravitational physics by finding and timing pulsars in extreme binary systems, such as a pulsar-black hole binary. We studied the computational requirements for beam forming and data analysis, assuming the SKADS (SKA Design Studies) design for the SKA, which consists of 15-meter dishes and an aperture array (AA). Beam forming of the 1-km core of the SKA requires no more than 2˙1015 ops. This number can be reduced when the dishes are placed in identical sub-arrays. Limiting the total field of view (FoV) of the AA to 3 deg 2, the maximum data rate from a pulsar survey using the 1-km core becomes about 2.7˙1013 bytes per second and requires a computation power of about 2.6˙1017 ops for a deep real-time analysis.
