Iceland HPC, Intel Thread problem, Intel Lineup

Doug Black, HPC Wire, HPC-as-a-Service Finds a Toehold in Iceland , here.  Cheap Bitcoin farming cycles.

While high-demand workloads (e.g., bitcoin mining) can overheat data center cooling capabilities, at least one data center infrastructure provider has announced an HPC-as-a-service offering that features 100 percent free and zero-carbon cooling.

Verne Global, a company seemingly intent on converting Iceland into a gigantic, renewably powered data center facility, has announce hpcDIRECT,  a scalable, bare metal service designed to support power-intensive high performance computing applications. Finding initial markets in the financial services, manufacturing (particularly automotive) and scientific research verticals, hpcDIRECT is powered by the island country’s abundant supply of hydroelectric, geothermal and, to a lesser degree, wind energy that the company says delivers 60 percent savings on power costs.

Joel Hruska, Extreme Tech, Major Hyper-Threading Flaw Destabilizes Intel Kaby Lake, Skylake CPUs, here.

Now, a major Hyper-Threading flaw has been discovered that can destabilize Intel CPUs based on both Kaby Lake and Skylake — not something Intel needed on the heels of AMD’s new CPUs. The issue is reported to cause “unpredictable system behavior,” which could mean anything from corrupting data to outright system crashes. The issue was picked up by Hot Hardware, via Debian.org. While Debian is a Linux distro, the warning makes it clear that the problem can happen to any operating system and is not limited to Linux.

Intel’s 2018 Roadmap Shows New High-End Cascade Lake-X Debuting Next Year, here.

2017 has been a banner year for CPU launches. AMD’s Ryzen debut in March kicked off its own aggressive hardware ramp, with the Ryzen 5 and Ryzen 3 families following in the spring and summer, and Raven Ridge debuting in the last few weeks. Intel’s Kaby Lake-X and Skylake-X launched in June, with Skylake-X offering faster performance and higher core counts for the same price than Intel had previously shipped. AMD’s Threadripper debuted in August with 16 cores at the same price as a 10-core Intel CPU (and a significant performance advantage), and Intel’s 18-core Skylake-X Core i9-7980XE retook the performance crown (though not the price/performance ratio) in September. Finally, the Core i7-8700K launched in October and won our top-end CPU recommendation, though the Ryzen 7 1800X is still quite competitive in well-threaded workstation workloads.
