Handling Big Data Scalability in Biological Domain Using Parallel and Distributed Processing: A Case of Three Biological Semantic Similarity Measures

Table 12

Enhanced SORA average time in the distributed system (2, 3 and 4 slaves) with input data divided equally.

Number of Gene Pairs	Original SORA Average Time (ns)	Threaded SORA Average Time (ns) (Input Data Divided Equally)			% Threaded SORA Average Time (Input Data Divided Equally) vs. Original SORA Average Time

X indicates that, due to limited memory, the system required many hours to find the similarity of some of the pairs.
