Power in the Hands of Developers

This is a very good initiative by IBM, ultimately now it will happen that the designing power will not be solely in the hands of the processor manufacturers, and the details of the hardware as well will be completely available with the software developers. Results depicted in the article are also interesting.

IMHO, a very important issue is: will the guys from GNU build compilers for Power8? Or they have already done it and I'm out of date?

from the "linked" ibm press release

"Recognizing Linux as a driving force for innovation, IBM last year committed $1 billion (USD) in new Linux and other open source technologies for IBM's Power Systems servers. Major"

Years ago Sun Microsystems took the pioneering leap of making its Sparc processor available as open hardware. No one went for it.

I don't think there is a burning design for an open hardware version of IBM's Power either. But I understand IBM would like there to be.

Google may surprise me. I am interested to see what it will do, though I suspect it will be very, very hard to find out.

Beside SUN now Oracle, Ross and Fujitsu designed Sparc processors. I have not heard anything of Ross for quite I while. But Oracle and Fujitsu still design Sparc processors.


BTW, what hapened to Ross, are they still in the market?

According to Wikipedia (the end of that section, just above the "Legacy" section): "Ross Technology closed down in 1998 and all its assets and patents became the property of Fujitsu Ltd."

many thank for your information about Ross Technology.

Ups, here in Germany we say "lesen bildet" which could be translated to "reading educates".

Another Ups, am I growing old? According to your information it is more than 15 years ago Ross vanished from the market.

The principals at Ross reorganized as Serverworks, a leading chipset supplier for Xeon-based servers back in the early 2000's. Serverworks' market share soared as Intel tried (unsuccessfully) to push Rambus-based chipsets into the server market, while Serverworks had a SDR/DDR/DDR2 road map. Intel realigned its server roadmap to be more in sync with standard DRAM technology, and Serverworks saw its place in the server chipset market fade away. Eventually Serverworks was acquired by Broadcom, and the key Ross principals moved onto other companies.

So this time one can watch IBM Power8 Arch. for better success as compared to previous IBM efforts. You are right that is also depends on IBM that how liberal they are going to treat licensing.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
