Description

This IDC insight begins our coverage of developments in IDC's Extreme Computing category, with a look at the new job scheduling software from eXludus. As the demand for computing resources continues to grow, especially in the technical computing market, the constraints on this growth ? physical, economical, intellectual ? have never been greater. As such, the incentive to fully and effectively utilize resources in both technical and enterprise computing datacenters has grown enormously. The adaptive, job-resource-requirement-aware scheduling software developed at eXludus is a novel technology that directly addresses this growing market need and therefore qualifies as an example of Extreme Computing at IDC.
