A 'cool' way of improving the reliability of HPC machines
2013
Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis on - SC '13
Preserved Fulltext
Our experimental results show that we can improve the reliability of a machine by a factor of 2.3 and reduce the execution time by 12%. ...
In this paper, we try to bridge this gap and explore the potential of combining both software and hardware aspects towards improving reliability of HPC machines. ...
We also thank Phil Miller and Shehla Saleem Rana for their valuable help in editing and proofreading the paper. ...

As a new business concept, machine-to-machine (M2M) communications are born from original telemetry technology with the intrinsic features of automatic data transmissions and measurement from remote sources ...
Furthermore, the progress of global M2M standardization is reviewed, and some representative applications (i.e., smart home, smart grid and health care) are given to show that the M2M technologies are ...
The rationale behind M2M communications is based on two observations: 1) a networked machine is more valuable than an isolated one; 2) when multiple machines are interconnected, more autonomous and intelligent ...
