Performance comparison in terms of filling the matrix, traceback, conversion to CIGAR strings, total computation time, and GCUPS

Calc. time (sec.)	Fill	Trace	Conv	Total	GCUPS
Editdist	0.436	0.104	0.076	0.616	7.19

Diff-raw	0.516	0.316	0.073	0.905	3.03
Libgaba	0.377	0.097	0.028	0.502	4.15
Edlib	26.0	18.8	0.109	44.9	13.23
SeqAn ED a	77.2				7.97
BWA-MEM global b	354	0.381		355	0.12
BLAST X-drop c	250				0.18
Parasail c	886				0.69

Results of comparison to existing implementations. Four adaptive banded DP implementations of ours (editdist, non-diff, diff-raw, and libgaba; top four rows) and four existing implementations (edlib, SeqAn ED, BWA-MEM global, BLAST X-drop, and Parasail; bottom five rows) were compared. See the main text for the details of the implementations. Columns: The average computation time per cell is shown in the Fill column. The time for traceback and CIGAR string conversion is shown in the Trace and Conv columns. The Total column presents the sum of Fill, Trace, and Conv. The GCUPS column shows the matrix fill-in performance in billion cell updates per second (GCUPS)

^aThe traceback and path-to-CIGAR conversion time for the SeqAn ED were not measured

^bThe path-to-CIGAR conversion field for the BWA-MEM global is blank because the implementation directly generates final CIGAR string

^cThe traceback and the path-to-CIGAR conversion fields are blank because the traceback routines were not implemented for the BLAST X-drop DP and the Farrar’s algorithm implementations that we used
