Abstract: A quasi-automatic method is provided to parallelize user programs with little or no changes in their original design, implementation or compiled binary code. The users issues a simple indication to inform a runtime system about the intent to run the programs in a parallel or distributed manner, and the runtime system executes a plurality of programs based on the original program to conduct the same computation with parallelization. The semantics of the original program is reused, and task instances are created based on the semantics and executed in parallel or distributedly. The method provides an easy yet reliable method for accelerating computation by distributing the original program processes on multiple computers. Through a semantics-aware I/O control and coordination, the runtime system improves the consistency between the logical result data generated by the parallel computation and the expected result data from the original program should it be executed on one computer.

Abstract: The invention relates to the isolation and the cloning and breeding application of a tobacco mosaic virus (TMV) resistant N'au gene. The invention discloses the nucleotide sequence of the TMV resistant N'au gene shown as SEQ ID NO.1. The amino acids of polypeptide encoded by the TMV resistant N'au gene are shown as SEQ ID NO.2. A non-transgenic TMV resistant tobacco variety can be obtained by transferring an N'au gene which is contained by germplasm resources into a TMV infected popular tobacco variety by conventional breeding means. The N'au gene of the invention has a homologous sequence with high identity rate of nucleotides in the popular tobacco variety, so that it is easy to obtain a shorter introgression segment single plant carrying the N'au gene by conventional breeding, and thereby to obtain a TMV resistant variety with lower linkage drag. The gene can resist both U1 strain and Cg strain of TMV.
