The 8-Bit Guy Disc-usses Floppy Drives

Tagged: floppy drive, apple, commodore, IBM

This video, about floppy disks, is a little bit longer and in-depth than their previous one about cassette tapes. The 8-Bit Guy and friends (I'm pretty sure they don't call themselves that...) goes through how many tracks each floppy have, how many sectors they have, and how that varies per-manufacturer (including the technical reasons of how and why they are formatted incompatibly).

The 8-Bit Guy likes to go through a bunch of hardware, spanning the gamut of Atari, Commodore, Apple, IBM PC, and others, and explain their history. The most interesting part of this video, to me, was his explanation of why the Commodore floppy drive was so much larger than its competitors, and what it meant for performance.

IBM is feeling Powerful in the Core Wars, details on the Power9 architecture have arrived

Subject: General Tech | April 7, 2016 - 03:43 PM |
Tagged: GLOBALFOUNDRIES, IBM, power9

IBM's Power9 processor is scheduled to appear on the scene just over a year from now and finally we have some details about what it will be.  Firstly the core count is to be two higher than Intel, 24 cores and is optimized for use in two socket servers.  The chips are 14nm FinFETs fabbed by GLOBALFOUNDRIES which will be compatible with modern industry standards including DDR4, PCIe 4.0 and NVLink 2.0 so you can even take advantage of Jen-Hsun's latest products. 

The list of customers is quite impressive, Google has moved to Power8 already and described changing to the infrastructure as simple as flipping a switch,  the US Department of Energy will build their next HPCs using Power9 and Rackspace is currently working with Google to develop Power9 server blueprints for the Open Compute Project. 

Several Chinese companies will take advantage of those OpenPower blueprints to develop their own 'partner chips', Power8 and 9 architecture which will be using 10nm gates in 2018 to 2020.  This is somewhat amusing considering the shipping of Xeon processors to China has been banned by the US Government.  Check out more of the slides from IBM's presentation at The Register.

"IBM's Power9 processor, due to arrive in the second half of next year, will have 24 cores, double that of today's Power8 chips, it emerged today.

Meanwhile, Google has gone public with its Power work – confirming it has ported many of its big-name web services to the architecture, and that rebuilding its stack for non-Intel gear is a simple switch flip."

Seagate joins the HPC super team

Subject: General Tech | July 13, 2015 - 01:31 PM |
Tagged: Seagate, IBM, HPC, hp

IBM will be making its Spectrum Scale software available on Seagate's ClusterStore HPC products, which are due out towards the end of the year.  This marks a turning point in Seagate's HPC business as previously their products were only useful to a small group of companies which used the Lustre file system, moving to IBM's product grows the available pool of customers significantly. HP will be adding their Apollo software suite into the deal making this even more attractive for potential clients.  As The Inquirer points out, this is part of the shift of international companies moving their data out of US borders, good news for ISPs and data providers in the rest of the world but not such good news for those looking for employment in the industry within the USA.

"We made a 7nm process chip and you can't have one!" - IBM

Subject: General Tech | July 9, 2015 - 02:30 PM |
Tagged: Samsung, IBM, GLOBALFOUNDRIES

The heavy hitting partnership of IBM, Samsung and GLOBALFOUNDRIES have designed and created the first chip built on a 7nm process using Silicon Germanium channel transistors and EUV lithography.  Even more impressive is their claim of 50% area scaling improvements ovver 10nm, a very large step in such small processes.  IBM told PC World that they will be able to fit 20 billion transistors on a 7nm chip which is a tenfold increase over Braswell as an example of current technology.  The Inquirer reports that this project also cements the deal between GLOFO and IBM; GLOFO will be the exclusive provider of chips for IBM for the next decade.

100Gbps optical interconnects anyone?

Subject: General Tech | June 16, 2015 - 12:49 PM |
Tagged: IBM, photonics

Almost a year ago IBM put $3 billion into research on developing and enhancing their existing photonics technology and putting it onto chips.  The Register has heard of their recent success in creating an integrated silicon photonics transceiver chip with multiplexed wavelengths, allowing multiple signals to be sent simultaneously without interference allowing the incredibly high bandwidth.  The example given to demonstrate what 100Gbps means is downloading an HD movie in 2 seconds, not too shabby at all.  The demonstration model exists, a big first step in photonic technology but we won't see it mass produced for a while yet.  This is a good first step in finally getting rid of copper and moving on to a new medium for data transfer.

Neither IBM nor the mainframe are dead yet

Subject: General Tech | January 15, 2015 - 01:10 PM |
Tagged: IBM, mainframe, power8

IBM has just released a new mainframe based on their new 5GHz 22nm Power8 based Processing Units with some models supporting up to 10TB of RAM, the minimum you can run is a mere 64GB.  It can not only run IBM's zOS but is also capable of directly supporting Linux and can be managed with a Blade running Windows if you so desire. These fancy looking little mainframes are set up with drawers of either 39 or 42 PUs, so you can upgrade as your usage requires although 2 are actually spares and 6 are System Assist Processors, the remaining PUs can be assigned to varying roles as in previous IBM Z models.  These machines are designed to handle large amounts of data traffic, providing real time encryption on up to 2.5 billion transactions per day.  The Register feels that the most likely usage scenario will be to provide secure mobile data traffic, something which is certainly needed.  You can also glean more information from this blog entry if you are curious about the architecture and capabilities of this mainframe.

"Of course, the proof of the pudding will be in the market, but IBM will be hoping that the billion dollars it's poured into developing the new z13 mainframe will get the big end of town as excited as Big Blue itself is."

Oak Ridge National Laboratory Chooses IBM and NVIDIA for Two Supercomputers, Summit and Sierra

Subject: General Tech, Systems | November 27, 2014 - 08:53 PM |
Tagged: nvidia, IBM, power9, Volta

The Oak Ridge National Laboratory has been interested in a successor for their Titan Supercomputer. Sponsored by the US Department of Energy, the new computer will be based on NVIDIA's Volta (GPU) and IBM's POWER9 (CPU) architectures. Its official name will be “Summit”, and it will have a little sibling, “Sierra”. Sierra, also based on Volta and POWER9, will be installed at the Lawrence Livermore National Laboratory.

The main feature of these supercomputers is expected to be “NVLink”, which is said to allow unified memory between CPU and GPU. This means that, if you have a workload that alternates rapidly between serial and parallel tasks, that you can save the lag in transferring memory between each switch. One example of this would be a series of for-each loops on a large data set with a bit of logic, checks, and conditional branches between. Memory management is like a lag between each chunk of work, especially across two banks of memory attached by a slow bus.

Summit and Sierra are both built by IBM, while Titan, Oak Ridge's previous supercomputer, was developed by Cray. Not much is known about the specifics of Sierra, but Summit will be about 5x-10x faster (peak computational throughput) than its predecessor at less than a fifth of the nodes. Despite the fewer nodes, it will suck down more total power (~10MW, up from Titan's ~9MW).

These two supercomputers are worth $325 million USD (combined). They are expected to go online in 2017. According to Reuters, an additional $100 million USD will go toward research into "extreme" supercomputing.

Intel's security on the silicon is starting to pay dividends

Subject: General Tech | September 8, 2014 - 12:52 PM |
Tagged: IBM, Intel, txt, mcafee

Intel have been diligently working on their Trusted Execution Technology to provide security on the actual silicon and with their purchaser of McAfee this technology has quickly improved over the past year.  IBM subsidiary Softlayer, who offer cloud storage, have announced that the will be implementing TXT along with the Intel Trusted Platform module to offer enhanced security on their servers.  This should make them attractive to government and law enforcement agencies which utilize clouds storage as well as businesses that need to keep their customers data secure.  They are not the first to consider TXT but are among the largest of vendors who are currently deploying servers that take advantage of the new security.  Check out more at The Register.

Ah, sweet nostalgia.  It seems like only a short while ago that Apple was saved by IBM, and Motorola, granting access to the PowerPC chips which were near the top of the field back in 1991.  The Motorola 68K was falling behind the Pentium MMX chips in PCs and Apple needed some way to compete in the market and the 200-MHz 603e PowerPC was the answer.  Now history is repeating itself with a partnership between IBM and Apple to bring iPhone apps to the enterprise, with apps specifically for enterprise environments as well as updates to existing apps to make them more enterprise friendly.  Read up on your history, or refresh your memories of times gone by as well as what this partnership will bring in the future on Slashdot.

"Apple and IBM, which just announced partnership to bring iOS and cloud services to enterprises, have helped each other before. IBM played a key role in turning the Macintosh into a successful hardware platform at a point when it — and the company itself — were struggling. Nearly 25 years ago, IBM was a part of an alliance that gave Apple access to PowerPC chips for Macintosh systems that were competitive, if not better performing in some benchmarks, than the processors Intel was producing at the time for Windows PCs."
