They introduced the architecture of coarse grain reconfigurable array (CGRA) for statically scheduled data flow computing in HOTCHIPS’17 and its software stack of compiler and linker in ICCAD’17. The new DGX-2, which achieves 2 petaFLOPS in the system, combines 16 fully interconnected GPUS with 10x the deep learning performance.

It's using software and coordination between the hypervisor and guest to improve performance. But not all workloads: some are network bound (proxies) and storage bound (databases). ## 5.

The growth in demand for software has consistently outpaced the growth in the supply of software developers. Each major expansion in software development - automation (60s), productivity (80s), internet (90s), mobile (00s) - has been additive to the total stock of software in the world. It's worth looking at why.

With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.

We have spent a great deal of time at ScaleOut Software re-architecting our in-memory data grid (IMDG)’s code base to make best use of many cores and large memory. Also, load-balancing after membership changes must be both multi-threaded and pipelined to drive the network at maximum bandwidth. Testing Scale-Up Performance.
