Is the human brain faster than a supercomputer?

This makes it seem as if computers are superior, but the truth is that the human brain is much more advanced and efficient and has more raw computing power than the most impressive supercomputers ever built. In contrast, our miraculous brains operate on the next order higher.

What is inside a supercomputer?

Photo: Supercomputer cluster: NASA’s Pleiades ICE Supercomputer is a cluster of 241,108 cores made from 158 racks of Silicon Graphics (SGI) workstations. That means it can easily be extendedto make a more powerful machine: it’s now about 15 times more powerful than when it was first built over a decade ago.

What is the architecture of the Cray T3E?

Cray T3E is a RISC (Reduced Instruction Set Computer) architecture which is very powerful microprocessors. T3E systems contain a large number of processing elements (PE). Each PE consists of a DEC Alpha EV5 RISC microprocessor. The system architecture is designed to tolerate latency and enhance scalability.

When did the first Cray T3E come out?

The first T3E was installed at the Pittsburgh Supercomputing Center in 1996. Like the previous Cray T3D, it was a fully distributed memory machine using a 3D torus topology interconnection network. The T3E initially used the DEC Alpha 21164 (EV5) microprocessor and was designed to scale from 8 to 2,176 Processing Elements (PEs).

What kind of microprocessor does Cray T3E use?

The T3E initially used the DEC Alpha 21164 (EV5) microprocessor and was designed to scale from 8 to 2,176 Processing Elements (PEs). Each PE had between 64 MB and 2 GB of DRAM and a 6-way interconnect router with a payload bandwidth of 480 MB/s in each direction.

What was the operating system of the T3E?

Unlike many other MPP systems, including the T3D, the T3E was fully self-hosted and ran the UNICOS /mk distributed operating system with a GigaRing I/O subsystem integrated into the torus for network, disk and tape I/O. The original T3E (retrospectively known as the T3E-600) had a 300 MHz processor clock.
