Abstract

Perhitungan Persamaan difusi neutron 2-dimensi telah berhasil diselesaikan secara paralel dengan menggunakan metoda Jacobi. Program ditulis dalam bahasa C++ menggunakan OpenMP. Dari proses benchmarking nilai fluks neutron dengan program FI-ITBCHI diperoleh bahwa kode program yang dibuat valid dengan akurasi hingga 6 angka penting. Hasil running program menunjukkan bahwa program yang dibuat bersifat scalable, baik pada prosesor single-core maupun multi-core. Nilai speedup tertinggi dicapai dengan menggunakan jumlah thread sama dengan jumlah core prosesor. Untuk prosesor dengan jumlah core 2 dicapai nilai speedup 1,28 sedangkan untuk core 4 nilai speedup-nya adalah 1,53.
