Nautilus is a Multi-threaded Distributed Shared Memory system based on scope consistency. The multithread implementation disallows the use of SIGIO signals and to minimize the context switch of traditional processes. This paper shows the speedups of some benchmarks submitted to Nautilus, being it compared with two other DSMs: TreadMarks and JIAJIA. This speedup comparison includes some benchmarks evaluation for different input sizes for each of them and a study of how the speedup behavior changes by increasing the input sizes. The benchmarks evaluated in this study are: LU (kernel from SPLASH II), Matmul (matrix multiplication) and SOR (from Rice University).
