Benchmarks of DEGAS 2 against EIRENE yield agreement to within 5% and comparable single processor run times. DEGAS 2 demonstrates a nearly linear increase in processing speed with the number of parallel processors. That speed is put to practical use here in the first runs of UEDGE coupled to DEGAS 2. The results of the coupled codes match those of coupled UEDGE and EIRENE. Additional algorithmic improvements such as use of the correlated sampling technique promise to make runs of the coupled UEDGE - DEGAS 2 codes practical for everyday use.
