When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.
Heterogeneous Scheduling for Performance and Programmability
SESSION: Doctoral Showcase - Dissertation Research Showcase
EVENT TYPE: Doctoral Showcase
TIME: 2:15PM - 2:30PM
SESSION CHAIR: Yong Chen
Presenter(s):Thomas R. W. Scogland
ROOM:155-F
ABSTRACT:
Heterogeneity is increasing at all levels of computing, with the rise of
accelerators such as GPUs, FPGAs, and other co-processors into everything from
desktops to supercomputers. More quietly it is increasing with the rise of NUMA
systems, hierarchical caching, OS noise, and a myriad of other factors. As
heterogeneity becomes a fact of life at every level of computing, efficiently
managing heterogeneous compute resources is becoming a critical task;
correspondingly however it increases complexity. Our work seeks to improve the
programmability of heterogeneous systems by providing runtime systems, and
proposed programming model extensions, which increase performance portability
and performance consistency while retaining a familiar programming model for the
user. The results so far are an extension to MPICH2 which automatically
increases the performance consistency of MPI applications in unbalanced systems
and a runtime scheduler which automatically distributes the iterations of
Accelerated OpenMP parallel regions across CPU and GPU resources.
