A Hard Look at the Two 2017 Coral Supercomputers

In this episode, the Radio Free HPC team meets at SC14 in New Orleans to discuss the recent news that Nvidia & IBM will build two Coral 150+ Petaflop Supercomputers in 2017 for Lawrence Livermore and Oak Ridge National Laboratories. The two machines will feature IBM POWER9 processors coupled with Nvidia’s future Volta GPU technology. NVLink will be a critical piece of the architecture as well, along with a system interconnect powered by Mellanox.

Henry thinks that IBM will have trouble delivering, and he reminds us what happened when they stumbled and pulled out of the Blue Waters deal at NCSA. Will this be the same story? Rich thinks they will come through, though probably 18 months late. Dan is being the pragmatic one this week. Go figure.

AWS Profitability - Ready for the Cloud Apocalypse?

In this episode, the Radio Free HPC team discuss the possibility of a future where the Big 3 (Amazon, Google, and Microsoft) figure out that Cloud is not profitable and pull the plug. If that Cloud Apocalypse sounds far fetched, check out these recent news nuggets:
  • An article in The Register that describes how Amazon lost money despite $20 Billion in revenue.
  • Business Week says that Amazon’s cloud unit, AWS, is one of the fastest-growing software businesses of all time, as Bloomberg Businessweek‘s Ashlee Vance recently wrote. It’s also in a hotly contested market. Google, Amazon, and Microsoft (MSFT) have been slashing prices to lure customers from one another.
  • The Wall Street Journal says that "The developments point to the possibility that profit margins in Amazon's cloud unit—believed to be much higher than its online retailing business—face a long-term squeeze that add to investor concerns about the company's profitability."
If you're more into numbers, the team has put together a spreadsheet of AWS revenue that does not paint a rosy picture.

Moving Processing out to the Network

In this podcast, the Radio Free HPC team discusses the concept of offloading computation to networked devices such a storage controllers. During a recent Analyst Call with Dan Olds, Mellanox described this technology as potential growth area. Henry wants to more about the interface to such and environment before he renders an opinion, while Rich notes that the companies like Solarflare have been doing this at the NIC level for level for several years now.

Summer 2014 Tech Reading

In this podcast, the Radio Free HPC team looks at a couple of techie books for Summer reading.
  • Flash Boys is about a small group of Wall Street guys who figure out that the U.S. stock market has been rigged for the benefit of insiders and that, post–financial crisis, the markets have become not more free but less, and more controlled by the big Wall Street banks. Working at different firms, they come to this realization separately; but after they discover one another, the flash boys band together and set out to reform the financial markets.
  • Daemon. When a designer of computer games dies, he leaves behind a program that unravels the Internet's interconnected world. It corrupts, kills, and runs independent of human control. It's up to Detective Peter Sebeck to wrest the world from the malevolent virtual enemy before its ultimate purpose is realized: to dismantle society and bring about a new world order.

Seven Myths of SSD vs. HDD Pricing

In this episode, the Radio Free HPC team looks at the Seven Myths of SSD vs. HDD Pricing, one of Henry's recent Slashdotted features at Enterprise Storage Forum.

In a nutshell, Henry thinks that the notion of SSDs replacing spinning disks in the datacenter is built on a series of flawed assumptions regarding flash storage.
  • First, some assume that the price of MLC NAND flash will continue to decrease at a rapid and predictable rate that will make it competitive with HDDs for bandwidth, and nearly for capacity, by 2014 or 2015. This downward trend, it is assumed, will make flash a viable alternative for large storage and to act as a memory or “buffer” to improve performance.
  • Second, there is a general assumption that prices for bandwidth ($/GB/s) for SSDs is much lower than for HDDs, and that enterprises will measure costs in these terms instead of capacity.
  • Third, there is no distinction made between flash in general, such as consumer SSDs, and enterprise storage SSDs. It is assumed that MLC NAND will not only reduce in price ($/GB) but also that it will increase in density and larger capacity drives will be developed.
  • Fourth, it is assumed that the quality of MLC NAND will either remain constant or increase as prices decrease and densities increase, allowing it to improve not only performance, but also reliability and power consumption of the systems it is used in.
  • Fifth, it is assumed that power consumption for SSDs is, or will shortly be, significantly lower than that of HDDs overall, on a per GB basis and on a per GB/s basis.
  • Sixth, they assume disk performance will grow at a constant rate of about 20 percent per generation and not improve.
  • Seventh, they assume file system data layout will not improve to allow better disk utilization.
According to Henry, most of these assumptions were made in early 2012. So far they have turned out to be partially true at best and wrong at worst. A big fan of the partially true, Dan pushes back as a matter of principle. Rich, on the other hand, has heard his share of SSD hype and thinks we need need to look at the data and see what it has to say.

The Coming Wave of Declustered RAID

In this podcast, the Radio Free HPC team looks at the coming wave of declustered RAID solutions designed to address the problem of ever-increasing RAID rebuild times. With 5 Terabyte drives in the wings, RAID cluster rebuild times are becoming impractical.

Dan is impressed with what IBM is doing in this area with GPFS.
Henry thinks these larger drives harken the death of RAID-5 and RAID-6.
Rich has been keeping a close watch on Xyratex and their ClusterStor GridRaid implementation.
Read the original paper on Declustered RAID by Garth Gibson and Mark Holland.

The RONNIEE Network Architecture

In this podcast, the Radio Free HPC team looks at the newly announced RONNIEE Network Architecture from A3 Cube. Rich did a slidecast with their CTO this week, but Dan and Henry need to know more and see this thing for themselves.

Following that, the conversation veers off into a grab bag of tech news for the week:
  • Dan's is still recovering from a rootkit that infected his business computer. We seem to recall that he was always backlogged before this happened, but we'll let it slide.
  • Henry is lamenting the lack of Google Fiber coming to Minnesota. Since Google tends to piggyback on the fastest Internet pipes, it looks like the state will forever be a third-world country in terms of bandwidth.
  • Rich is excited about the Outernet project, which hopes to launch a series of satellites that will provide free Internet connectivity worldwide to anyone who wants it.
