An Improved Solution to I/O Support Problems in Wide Area Grid Computing Environments
نویسندگان
چکیده
In wide area Grid computing environments, computation is often performed at a site distant from data needed and from the user console. Therefore, it necessitates I/O support to run computation jobs at remote sites. Major Grid software providers have implemented their own I/O solutions. However, in existing solutions, two important user requirements for I/O support are not satisfied, namely, run-time standard input from user console and runtime stage-out of scratched files during computation. Regarding these deficiencies, the paper puts forward an improved I/O support solution. In addition, the paper presents a reference implementations and describes application experience of our implementation in PCG(PACT Computational Grid) project.

With growing computational power of current supercomputers, scientific computing applications can work on larger problems. The corresponding increase in dataset size is often correlated to an increase in needed storage for the results. Current storage area networks (sans) balance i/o load on multiple disks using high speed networks, but are integrated on the operating system level, demanding ad...
