The Week / Competitive it is

Hance Haney, Disco-tech blog: M
y colleague George Gilder and I have completed a paper, entitled “More Broadband, Increased Choice and Lower Prices Begin with Regulatory Reform.” We examine various shortcomings in telecom regulation in Illinois, Michigan, Ohio and Wisconsin as a result of robust competition. We explain why regulation and competition don't mix, and offer legislators specific ideas for regulatory reform.

 

A chart, which appears in the paper, projects the growth in competition from cell phones and Internet Protocol-enabled voice services provided by cable operators. The curve is in the shape of a hockey stick.

 

Phone competition from cable operators took off beginning in 2004 as a result of the FCC scaling back its wholesale competition rules. Those changes prompted phone companies to enter the video market dominated by cable operators, who in turn accelerated their entry into the voice market dominated by incumbent phone companies.

 

When the 1996 law passed, several cable operators planned to offer competitive phone services in a venture that included Sprint Corp. But according to Sprint CEO William T. Esrey, the plans were dropped because of the FCC’s “pro-competition” policies: “If we provided telephony service over cable, we recognized that they would have to make it available to competitors.” Thus, the local competition rules which were intended to speed effective competition actually delayed it.

 

Consumers also began substituting cell phones for fixed line service in greater numbers beginning in approximately 2004. During the Clinton administration, additional spectrum was auctioned for cell phone services and state regulation was preempted. Service quality steadily improved and prices steadily dropped, both as a result of these policies and technological innovation. Cell phone service -- which was once expensive and unreliable -- is increasingly becoming a compelling alternative to fixed line phone service. Also, at the end of 2003 the FCC mandated wireline-to-wireless number portablility -- enabling you to cancel your fixed line phone service and transfer your wireline phone number to a cell phone.

 

The point is that it is time to reform telecom regulation. The phone company which Lily Tomlin ("Ernestine") lampooned (e.g., "We're the phone company; we're omnipotent.") on Rowan & Martin's Laugh-In program that aired on NBC from 1968 to 1973 no longer exists.

Heard at Hot Chips

20 Years of What Worked and
What Didn't in CPU Architecture

 

Ron Wilson, Electronic Design, Strategy, News (8/26/08): You might imagine that somewhere in a back room at conferences the old hands at microprocessor architecture get together over dinner and a few bottles of wine--the sort that must be concealed in expense reports--lean back in their chairs, and talk long into the night about lessons learned and lessons repeated. Last night the minority of  Hot Chips attendees who stayed around after dinner had the privilege of listening in on just such a discussion, staged as a panel.

 

And an august group is it was. Chaired by [Gilder Telecosm Forum’s] Nick Tredennick, who has been in microprocessor design since the Motorola 68000 development, the panel included Insight 64 analyst Nathan Brookwood, Intel vice president and low-power processor pioneer Dave Ditzel, Techvision principal and MIPS pioneer John Mashey, the legendary Berkeley professor and RISC champion David Patterson, former Intergraph guru Howard Sachs of Telarity, and Microprocessor Report founder Michael Slater. As Tredennick said in his opening remarks, "these men need no introduction—if you don't recognize them, just ask your parents."

 

Setting the tone, Tredennick characterized the industry has having been "fooled by randomness." Architecture is not a science, he argued, because it has only self-validation. "An architect creates a new architecture, and then we let him tell us about all its advantages and conceal all its problems. It's like trying to form an opinion of kids by asking their parents. We should be asking the neighbors."

 

The tone of the panel remained similarly light. But inevitably, when people of this caliber get together, some profound thoughts precipitated out of the levity. And given the diversity of experience on the panel, their observations were remarkably consistent. Taken together, they could almost form a little handbook of how to, and not to, do a CPU architecture.

 

Perhaps the first point on which many of the panelists remarked was the inverse correlation--or perhaps, after anti-x86 bias is removed, lack of correlation--between architectural elegance and market success in the processor world. (Given their backgrounds, the panelists focused on the PC and server processing world, not the embedded space.) Hardly anyone would consider the x86 instruction set architecture to be pleasant, let alone elegant, but it has utterly dominated the market. In fact one of the lessons many of the panelists cited was a simple truth: don't go up against x86.

 

Another key point was the persistence of software. Noting that C, now an ancient language, had defeated all attempts to supplant it, and that some applications still used FORTRAN, Mashey observed "Chips come and go, but software is forever." To apply this aphorism, he pointed out that a new instruction set architecture requires someone to write new operating software, and that is extremely hard and slow. "A really cool chip can mean there is no software for it," Mashey said. Special mention in the category of creating an impossible software problem was reserved for IBM's Cell processor, which, Ditzel pointed out, has not one but two proprietary instruction sets on one chip.

 

Another point made by the panelists is that, on the whole, the pursuit of instruction-level parallelism had proved frustrating. Nearly a decade ago academic researchers warned that the best average number of instructions per clock on a broad mix of codes might be below 4, no matter how clever the compiler technology. Ignoring this, CPU architects pushed for ever more aggressive hardware, including wide instruction buffers, out-of-order execution, branch prediction, and even speculative execution, to make the machines capable of executing more and more instructions in parallel. The ultimate expression of this trend was the long infatuation in some circles with VLIW (very long instruction word) machines, in which the compiler bore almost all the responsibility for recognizing and preparing instructions for parallel execution, and parallel execution pipe numbers reached toward a dozen. But in the end, the academics proved to have been correct. "I think we have to call VLIW and superscalar approaches near misses," Patterson said.

 

In contrast, Patterson pointed out—and others agreed—that one concept that had caught on was SIMD (single-instruction, multiple-data) instructions for exploiting parallelism that lies in the data, rather than in the instruction stream. Ditzel even suggested that vector processors, an elaboration on the SIMD concept, might see a resurgence of interest as architects struggle to exploit data parallelism while minimizing energy consumption.

 

The question of power—whether power density for thermal reasons or total energy consumption for battery-life reasons—also marked a number of comments during the discussion. Ditzel perhaps put it most succinctly: "The quest for low power is driving a return to simplicity in processor architecture." He pointed out, for example, that the just-announced Intel Larrabee processor uses a simple, short execution pipeline based on a 1992 Pentium design—for power reasons.

 

Other panelists added to this point. Patterson cited superpipelining, in which some architects claimed performance advantages for pipelines as long as 50 stages, as one of the conspicuous failures in the search for performance. He observed that lately, pipelines have been getting shorter, not longer. Brookwood said "performance/Watt considerations will bring us back to using simple, in-order execution pipelines. We just can't afford the power necessary to run all that extra hardware to manage out-of-order execution, and to speculatively execute instructions that we will subsequently throw away."

 

Instead, the panelists saw a return to simplicity throughout the architectural world. The old debate between architects who relied on complexity to execute ever more instructions per clock and those who relied on simplicity to increase clock frequency seems to have finally been resolved, in favor of simplicity. In the future, it was suggested, we will use our growing transistor budgets to build lots of fast, simple machines with aggressive, smart power management, rather than to build highly complex machines. Moore's Law, which in the past conquered bipolar ECL, GaAs, and SiGe, appears to have slain architectural complexity as well.

Friday Blogger Bonus / The Micro-blogging Movement

Technology Review’s 2008 Young Innovator:


In 2006, Jack Dorsey created Twitter so that he could let friends and family know what he was doing, wherever he--or they--might be. Today more than two million people use it to send out 140-character-or-fewer updates, called "tweets," through Twitter's website or by text message over mobile devices. Dorsey's ethos of simplicity shapes everything about Twitter, from the application itself to the company's San Francisco offices (see "Home Tweet Home," July/August 2008). Twitter's popularity has given rise to an entire eco­system of applications. Yet Dorsey, cofounder and now CEO of the bemusing micro­blogging service, is secretive about how Twitter will ever make money; critics say that's because its executives have no idea. What's not a secret is that Twitter has had difficulties supporting its growing band of obsessives: in recent months, twitterers have been frequently confronted by error screens bearing messages such as "Twitte­r is stressing out a bit right now." 

 

Jason Pontin, TR's editor in chief, recently chatted with Dorsey about these and other issues using Twitter's @reply function, which directs a public message to a particular user.

jason_pontin @jack Explain Twitter.

 

jack @jason_pontin Twitter is a real-time repository of state for people, events, & things. A personal news wire of sorts.

 

jason_pontin @jack I twitter every day. But whenever I explain it to people who've not, they are uncomprehending or angry. Why?

 

jack @jason_pontin People have to discover value for themselves. Especially w/ something as simple & subtle as Twitter. It's what you make of it.

 

jason_pontin @jack Critics say that tweets are trivial. Is that missing the point?

 

jack @jason_pontin It depends on the context the recipient brings. There's a universe in the smallest, most "trivial" details of one's life.

 

jason_pontin @jack Even people who love Twitter are frustrated by the service. It's broken far too often to feel reliable.

 

jack @jason_pontin We love what we're building & we hate to see it suffer. Our goal is to make it reliable enough to be trusted as a public good.

 

jason_pontin @jack Twitter also seems to lack basic stuff. I can't organize my followers intelligently. Or search very well. When will Twitter grow up?

 

jack @jason_pontin Unfortunately, we've neglected the user experience to focus on stability of the foundation. We have designs to put this right.

 

jason_pontin @jack You recently got $15 million from Spark Capital and Bezos Expeditions. Will you buy some servers and infrastructure with that?

 

jack @jason_pontin I can't confirm the number, but I can confirm we'll make the money work for our users (20 of whom happen to be our investors)!

 

jason_pontin @jack What's Twitter's business model?

 

jack @jason_pontin We're building what we love. While we have many ideas for sustainable revenue, Twitter's will emerge naturally from our work.

 

jason_pontin @jack Sometimes it sounds like your monetization plan is: let's get acquired by a communications company.

 

jack @jason_pontin We're not focused on answering that question. We're determined to build a solid platform and service we can take all the way.
