Performance dependency on number of threads and query length. The speed in billion cell updates per second (GCUPS) of BLAST (red), BLAST+ (orange), SWIPE (black), SSW (green), Parasail’s striped SW implementation using SSE4.1 (light blue) and AVX2 (dark blue) instruction sets, as well as libssa using SSE4.1 (purple) and AVX2 (gray), using a variable number of threads and queries of varying length. Opal is only evaluated in c since the application was single-threaded (SSE4.1 as pink, AVX2 as brown). a Number of threads ranging from 1 to 24 and the 375 residue long P07327 query sequence. b Query sequences ranging from 24 to 5478 residues in length and 24 threads. c Query sequences of varying length and 1 thread. All scales are logarithmic. The BLOSUM62 matrix and gap open and extension penalties of 11 and 1, respectively, were used in all cases. This figure corresponds to Figure 6 in Rognes [8]
