Spawns n threads and sorts 1/nth of the data using each thread. All the data is stored in a single shared memory. At the completion of the individual sort operation, the manager thread merges the result of each worker and writes it to the stdout.
Usage:
psort <input-file>The first line of input-file contains the total number of elements (n). The n subsequent lines then contain a single number that can be represented as uint64_t.
