Abstract
The computing environment at the King Abdullah University of Science and Technology (KAUST) is growing in size and complexity. KAUST hosts the tenth fastest supercomputer in the world (Shaheen II) and several HPC clusters. Researchers can be inhibited by the complexity, as they need to learn new languages and execute many tasks in order to access the HPC clusters and the supercomputer. In order to simplify the access, we have developed an interface between the applications and the clusters and supercomputer that automates the transfer of input data and job submission and also the retrieval of results to the researcher’s local workstation. The innovation is that the user now submits his jobs from within the application GUI on his workstation, and does not have to directly log into the clusters or supercomputer anymore. This article details the solution and its benefits to the researchers.
Highlights
The computing landscape of the King Abdullah University of Science and Technology (KAUST) is increasing in complexity
This leads to reduced time-to-solution, easier access to the HPC systems, and less time spent on mastering unfamiliar Linux commands
We show that we can simplify the workflow of a user of HPC resources considerably by automating the workflow sequence: logging into the HPC system, job submission and transfer of input and output data
Summary
The computing landscape of the King Abdullah University of Science and Technology (KAUST) is increasing in complexity. The user submits his jobs to the cluster from within the application GUI on his workstation, and does not have to physically go onto the cluster anymore This leads to reduced time-to-solution, easier access to the HPC systems, and less time spent on mastering unfamiliar Linux commands. The HPC Gateway, originally called SynfiniWay [5], and before that TAO-W, is a virtualized IT framework developed by Fujitsu that provides a uniform and global view of resources within a department, a company, or a company with its suppliers It includes the linking of jobs in a workflow. The novelty of the present work is that we configure remote job submission by using the vendor-supplied implementation in the applications This allows us to configure the access to HPC resources in such a way, that the user can stay in the application GUI
