Researchers Unveil New Password Meter that will Change How Users Make Passwords

May 11, 2017

One of the most popular passwords in 2016 was "qwertyuiop," even though most password meters will tell you how weak that is. The problem is no existing meters offer any good advice to make it better—until now. Researchers from Carnegie Mellon University and the University of Chicago have just unveiled a new, state-of-the-art password meter that offers real-time feedback and advice to help people create better passwords. To evaluate its performance, the team conducted an online study in which they asked 4,509 people to use it to create a password. "Instead of just having a meter say, 'Your password is bad,' we thought it would be useful for the meter to say, 'Here's why it's bad and here's how you could do better,'" says CyLab Security and Privacy Institute faculty Nicolas Christin, a professor in the department of Engineering and Public Policy and the Institute for Software Research at Carnegie Mellon, and a co-author of the study. The study will be presented at this week's CHI 2017 conference in Denver, Colorado, where it will also receive a "Best Paper Award." This data-driven feedback is presented in real-time, as a user is typing their password out letter-by-letter. The team has open-sourced their meter on GitHub.

AI Technology from China Helps Radiologists Detect Lung Cancer

May 11, 2017

Today Infervision introduced its innovative, deep learning solution to help radiologists identify suspicious lesions and nodules in lung cancer patients faster than ever before. The Infervision AI platform is the world’s first to reshape the workflow of radiologists and it is already showing dramatic results at several top hospitals in China. Infervision’s AI-aided CT diagnosis, with its high-performance parallel computing power, effectively learns the core characteristics of lung cancer and efficiently detects suspected cancer features in different CT image sequences, helping with early diagnosis and consequently early treatment. The technology is also used to assist in X-ray diagnosis and has achieved extremely high accuracy so that it is close to that of a deputy chief physician in the diagnosis of cardiothoracic diseases at one of the top Chinese hospitals where the software is now in use. For the past six months, the technology has been in use at several top hospitals in China, a country experiencing hundreds of thousands of new lung cancer patients annually, while it has too few radiologists. After rigorous testing and integrating the software with the standard PACS (picture archiving and communication system), Infervision’s technology is proving to be extremely effective and is enhancing the work of Chinese doctors by acting as a second pair of eyes.

NCSA Highlights Scientific Impacts from Three Years of Blue Waters

May 11, 2017

“Build it and they will come” is one way to approach building a supercomputer, but it’s not what the National Center for Supercomputing Applications (NCSA) did with Blue Waters, the largest leadership-class National Science Foundation supercomputer. Prior to the system going online in April 2013, Blue Waters staff worked with more than 20 science teams to determine a unique, balanced hardware configuration—a process now known as co-design. Three years later, a sample of 31 science teams that have used Blue Waters were surveyed and interviewed as part of a report meant to judge the effectiveness and productivity of this unique system—housed at NCSA’s home institution, the University of Illinois at Urbana-Champaign. Using information gathered in the surveys, the report’s authors at International Data Corporation’s HPC division (now known as Hyperion Research) ranked the impact of each team’s findings into an “innovation index”—using a methodology they developed to analyze the effectiveness of 700-plus scientific projects, including international HPC projects. The Hyperion Research analysts noted in the report that “NCSA did an unusually thorough job of preparing [science teams] for Blue Waters.” Read more at https://www.hpcwire.com/off-the-wire/ncsa-highlights-scientific-impacts-three-years-blue-waters/

NASA Issues a Challenge to Speed Up Its ‘FUN3D’ Supercomputer Code

May 11, 2017

Do you, or someone you know, know how to program computers? NASA has a challenging assignment for you. NASA’s aeronautical innovators are sponsoring a competition to reward qualified contenders who can manipulate the agency’s FUN3D design software so it runs ten to 10,000 times faster on the Pleiades supercomputer without any decrease in accuracy. The competition is called the High Performance Fast Computing Challenge (HPFCC). “This is the ultimate ‘geek’ dream assignment,” said Doug Rohn, director of NASA’s Transformative Aeronautics Concepts Program (TACP). “Helping NASA speed up its software to help advance our aviation research is a win-win for all.” NASA’s aviation research is based on what is often described as a three-legged stool. One leg sees initial designs tested with computational fluid dynamics, or CFD, which relies on a supercomputer for numerical analysis and data structures to solve and analyze problems.

Reaching for the Stormy Cloud with Chameleon

May 11, 2017

Some scientists dream about big data. The dream bridges two divided realms. One realm holds lofty peaks of number-crunching scientific computation. Endless waves of big data analysis line the other realm. A deep chasm separates the two. Discoveries await those who cross these estranged lands. Unfortunately, data cannot move seamlessly between Hadoop (HDFS) and parallel file systems (PFS). Scientists who want to take advantage of the big data analytics available on Hadoop must copy data from parallel file systems. That can slow workflows to a crawl, especially those with terabytes of data. Computer Scientists working in Xian-He Sun's group are bridging the file system gap with a cross-platform Hadoop reader called PortHadoop, short for portable Hadoop. "PortHadoop, the system we developed, moves the data directly from the parallel file system to Hadoop's memory instead of copying from disk to disk," said Xian-He Sun, Distinguished Professor of Computer Science at the Illinois Institute of Technology. Sun's PortHadoop research was funded by the National Science Foundation and the NASA Advanced Information Systems Technology Program (AIST). The concept of 'virtual blocks' helps bridge the two systems by mapping data from parallel file systems directly into Hadoop memory, creating a virtual HDFS environment. These 'virtual blocks' reside in the centralized namespace in HDFS NameNode. The HDFS MapReduce application cannot see the 'virtual blocks'; a map task triggers the MPI file read procedure and fetches the data from the remote PFS before its Mapper function processes its data. In other words, a dexterous slight-of-hand from PortHadoop tricks the HDFS to skip the costly I/O operations and data replications it usually expects.Learn more at https://www.tacc.utexas.edu/-/reaching-for-the-stormy-cloud-with-chameleon

SDSC to Double ‘Comet’ Supercomputer’s Graphic Processor Count

May 11, 2017

The San Diego Supercomputer Center (SDSC) at the University of California San Diego has been granted a supplemental award from the National Science Foundation (NSF) to double the number of graphic processing units, or GPUs, on its petascale-level Comet supercomputer in direct response to growing demand for GPU computing across a wide range of research domains. Under the supplemental NSF award, valued at just over $900,000, SDSC is expanding the high-performance computing resource with the addition of 36 GPU nodes, each with four NVIDIA P100s, for a total of 144 GPUs. This will double the number of GPUs on Comet from the current 144 to 288. The nodes are being provided by Dell, the vendor and co-design partner for Comet. They are expected to be in production by early July. The expansion will make Comet the largest provider of GPU resources available to the NSF-funded Extreme Science and Engineering Discovery Environment (XSEDE), a national partnership of institutions that provides academic researchers with the most advanced collection of digital resources and services in the world. Prior to this award, the NSF granted SDSC a total of $24 million to develop and operate Comet, which went into production in mid-2015. Once used primarily for video game display graphics, today’s much more powerful GPUs have been developed that have more accuracy, speed, and accessible memory for more scientific applications that range from phylogenetics and molecular dynamics to creating some the most detailed seismic simulations ever made to better predict ground motions to save lives and minimize property damage.

Intel Consolidates Xeon Product Lines

May 11, 2017

The much-anticipated unification of Intel’s Xeon E3, E5 and E7 product lines is upon us. Starting with the upcoming “Skylake” datacenter chips, all Xeons will now fall under the new Xeon Scalable Processor (SP) family. As a result, the Xeon EP, and EX suffixes are being consolidated into a single SP designation. However, under the new structure, Intel has come up with four processor levels: Platinum, Gold, Silver, and Bronze. It’s anticipated that the old E3 (single-socket), E5 (dual-socket) and E7 (quad-socket/multi-socket) will map to the Silver, Gold and Platinum levels, respectively, but since four levels need to be filled, it’s likely to get a bit more nuanced than that. In any case, Intel is using the announcement of the new family to tee up the Skylake silicon, which according to an editorial penned by Intel VP and GM Lisa Spelman, represents “the biggest set of data center platform advancements in this decade.” Skylake will include a number of integrated “performance accelerators,” namely the 512-bit Advanced Vector Extensions (AVX-512), QuickAssist Technology (QAT), and the Volume Management Device (VMD). Not all Skylake SP chips will include all these accelerators. Rather, they will be distributed across the various levels and individual SKUs based on their anticipated target audience.

Study Finds Gender Bias in Open-Source Programming

May 4, 2017

A study comparing acceptance rates of contributions from men and women in an open-source software community finds that, overall, women's contributions tend to be accepted more often than men's - but when a woman's gender is identifiable, they are rejected more often. "There are a number of questions and concerns related to gender bias in computer programming, but this project was focused on one specific research question: To what extent does gender bias exist when pull requests are judged on GitHub?" says Emerson Murphy-Hill, corresponding author of a paper on the study and an associate professor of computer science at North Carolina State University. GitHub is an online programming community that fosters collaboration on open-source software projects. When people identify ways to improve code on a given project, they submit a "pull request." Those pull requests are then approved or denied by "insiders," the programmers who are responsible for overseeing the project. Read more at https://phys.org/news/2017-05-gender-bias-open-source.html

Supercomputers assist in search for new, better cancer drugs

May 4, 2017

Surgery and radiation remove, kill, or damage cancer cells in a certain area. But chemotherapy—which uses medicines or drugs to treat cancer—can work throughout the whole body, killing cancer cells that have spread far from the original tumor. Finding new drugs that can more effectively kill cancer cells or disrupt the growth of tumors is one way to improve survival rates for ailing patients. Increasingly, researchers looking to uncover and test new drugs use powerful supercomputers like those developed and deployed by the Texas Advanced Computing Center (TACC). "Advanced computing is a cornerstone of drug design and the theoretical testing of drugs," said Matt Vaughn, TACC's Director of Life Science Computing. "The sheer number of potential combinations that can be screened in parallel before you ever go in the laboratory makes resources like those at TACC invaluable for cancer research." Three projects powered by TACC supercomputer, which use virtual screening, molecular modeling and evolutionary analyses, respectively, to explore chemotherapeutic compounds, exemplify the type of cancer research advanced computing enables.

IBM "Minsky" Cluster Achieves Billion-Cell Reservoir Simulation in Record Time

May 4, 2017

A 30-node cluster of GPU-accelerated IBM “Minsky” servers has performed a billion-cell petroleum reservoir simulation in 92 minutes. Previous attempts at this scale required 20 hours using a large supercomputer with thousands of processors. Oil and gas companies rely on reservoir simulations to help figure out the most productive spots to drill. But since these simulations are so computationally demanding, typical runs use 10 to 100 million cells, although Saudi Aramco managed to achieve a trillion-cell reservoir simulation last year using its Cray XC 40 supercomputer. Nonetheless, a billion-cell simulation is rarely practical in most HPC setups at oil and gas companies. However, the level of resolution provided by such a detailed model can help lower production costs and environmental risks, allowing drillers to extract more oil from a given reservoir. The billion-cell run took advantage of the latest P100 Tesla GPUs from NVIDIA. To make the most of these devices, the simulation was performed using ECHELON, a petroleum reservoir simulation package from Stone Ridge Technology that is highly optimized for GPU acceleration. Stone Ridge Technology president Vincent Natoli noted that the fast turnaround time now possible for such a detailed simulation will enable reservoir engineers to run more models, making oil drilling and production more efficient. “By increasing compute performance and efficiency by more than an order of magnitude, we’re democratizing HPC for the reservoir simulation community,” said Natoli.

MIT Professor Runs Record Google Compute Engine job with 220K Cores

May 4, 2017

Over at the Google Blog, Alex Barrett writes that an MIT math professor recently broke the record for the largest-ever Compute Engine cluster, with 220,000 cores on Preemptible VMs. According to Google, this is the largest known HPC cluster to ever run in the public cloud. “Andrew V. Sutherland is a computational number theorist and Principal Research Scientist at MIT, and is using Compute Engine to explore generalizations of the Sato-Tate Conjecture and the conjecture of Birch and Swinnerton-Dyer to curves of higher genus. In his latest run, he explored 1017 hyperelliptic curves of genus 3 in an effort to find curves whose L-functions can be easily computed, and which have potentially interesting Sato-Tate distributions. This yielded about 70,000 curves of interest, each of which will eventually have its own entry in the L-functions and Modular Forms Database (LMFDB).” The flexibility of the Google Compute Engine was key for Sutherland in his quest to explore generalizations of the Sato-Tate Conjecture and the conjecture of Birch and Swinnerton-Dyer to curves of higher genus.

Call for Papers: High Performance Computing for Big Data

May 4, 2017

4th International Workshop on High Performance Computing for Big Data (HPC4BD 2017) to be held in conjunction with the 46th International Conference on Parallel Processing (ICPP), August 14, 2017 at Bristol, United Kingdom. Scope and Topics of Interest: Processing large datasets for extracting information and knowledge has always been a fundamental problem. Today this problem is further exacerbated, as the data a researcher or a company needs to cope with can be immense in terms of volume, distributed in terms of location, and unstructured in terms of format. Recent advances in computer hardware and storage technologies have allowed us to gather, store, and analyze such large-scale data. However, without scalable and cost effective algorithms that utilize the resources in an efficient way, neither the resources nor the data itself can serve to science and society at its full potential.
