mnemotronic writes: Igor Gamow, inventor of the "Gamow bag", a portable hyperbaric chamber for treatment of altitude or Acute Mountain Sickness (AMS), has died. He is credited or co-credited with other inventions including prosthetics for amputees. His career at the University of Colorado in Boulder was marred by accusations from multiple sources of sexual predation. He is one of only three tenured professors ever to be fired by CU Boulder since it's founding in 1876.

Submission + - NCSU Researchers Propose to Speedup 3D Xpoint Memory (ieee.org)

Submitted by mnemotronic on Wednesday June 20, 2018 @10:46AM

mnemotronic writes: At the 45th ICSA (International Symposium on Computer Architecture), a group of researchers from North Carolina State University led by Prof. Yan Solihin proposed a method called lazy consistency to speedup write operations to 3d XPoint memory. XPoint, developed by Intel and Micron, is non-volatile, cheaper and denser than DRAM but requires more power and writing takes longer. The method proposed reduces write overhead times from 9% to 1% by incorporating a checksum to the cache memory system.
The researchers were not able to verify their approach on actual XPoint memory, as those products only recently started sampling. They tested using simulations and DRAM and plan to verify when Intel's modules become more widely available.
