From FLOPS to IOPS: The New Bottlenecks of Scientific Computing
More than a decade ago, the pioneering computer scientist Jim Gray envisioned a fourth paradigm of scientific discovery that uses computers to solve data-intensive scientific problems. Today, scientific discovery, whether observational, in-silico or experimental,...
Academics Should Build Their Own Computers to Advance Systems Research
This is a time of great interest in new hardware. Computers are becoming much more complex. The multicore era has given way to increasingly heterogeneous computing platforms. Modern SoCs contain a tremendous variety of processors, accelerators, and peripheral devices,...
The Looming Network Wall in Data-Intensive Computing
Fast, RDMA-capable networks present a “network wall” for data-intensive applications in a data center. Software developers are facing two unpalatable choices: either communicate using messages and re-implement features of TCP/IP in their application, or...
