Title
Experimental evaluation of a flexible I/O architecture for accelerating workflow engines in cloud environments.
Abstract
In the current scientific computing scenario storage systems are one of the main bottlenecks in computing platforms. This issue affects both traditional high performance computing systems and modern systems based on cloud platforms. Accelerating the I/O subsystems can improve the overall performance of the applications. In this paper, we present Hercules as an I/O accelerator specially designed for improving I/O access in workflow engines deployed over cloud-based infraestructures. Hercules provides a dynamic and flexible in-memory storage platform based on NoSQL-based distributed memory systems. In addition, Hercules offers a user-level interface based on POSIX for facilitating its usage on existing solutions and legacy applications. We have evaluated the proposed solution in a public cloud environment, in this case Amazon EC2. The results show that Hercules provides a scalable I/O solution with remarkable performance, especially for write operations, compared with classic I/O approaches for high performance computing in cloud environments.
