His contribution may turn a corner in working with GPU applications, He just released a programming language called Harlan. It’s all new and it’s totally dedicated to building applications that run GPUs. The Harlan creator is Eric Holk of Indiana University. As a doctoral candidate, his interests, he said, focus on designing and implementing programming languages that can ease up the production of reliable software that performs well. Easier professed than done, some may argue, when it comes to involvement with GPUs. © 2013 Phys.org Citation: Indiana University student offers Harlan programming language for GPUs (2013, July 4) retrieved 18 August 2019 from https://phys.org/news/2013-07-indiana-university-student-harlan-language.htmlcenter_img Explore further Tech sites reviewing his achievement say he has taken on quite a challenge. Programming for GPUs, as ExtremeTech put it, calls for a type of programmer who is willing to spend “a lot of brain cycles dealing with low-level details which distract from the main purpose of the code.” Holk stuck to it, attempting to answer his own question: What if a language could be built up from scratch, designed from the start to support GPU programming? Harlan is special in that it can take care of the “grunt work” of GPU programming.A few key points about Harlan: (1) It can be compiled to OpenCL and can make use of the higher-level languages, Python and Ruby. (2) Syntax is based on Scheme, which is based on Lisp. Actually, when you start talking about Scheme, you become more immersed in Schemes of things. The Petite Chez Scheme is available for download. Chez Scheme is an implementation of Scheme based on an incremental optimizing compiler that produces code quickly. Petite Chez Scheme is a Scheme system compatible with Chez Scheme but uses a fast interpreter in place of the compiler. It was conceived as a runtime environment for compiled Chez Scheme applications, but can also be used as a standalone Scheme system. (3) Harlan runs on Mac OS X 10.6 (Snow Leopard), Mac OS X 10.7 (Lion), Mac OS X 10.8 (Mountain Lion), and “various flavors” of Linux. The github definition of Harlan calls it “a declarative, domain specific language for programming GPUs.” According to the site, OpenCL implementations that should work.include the Intel OpenCL SDK, NVIDIA CUDA Toolkit, AMD Accelerated Parallel Processing (APP) SDK.Holk announced Harlan in his blog as now available to the public as the result of about two years of work “Harlan,” he stated, “aims to push the expressiveness of languages available for the GPU further than has been done before.” He made note of its native support for rich data structures, including trees and ragged arrays.

Researchers demonstrate reconfigurable clusters made of colloidal particles as a form of

first_img © 2014 Phys.org The cooperative effects of tension and elasticity Explore further Colloids are substances made of either large molecules or other tiny particles that are dispersed in another substance—examples include gels, emulsions and sols. The particles do not settle and therefore remain distributed throughout the second substance. In this new research the particles were very tiny dimpled spheres suspended in a clear liquid. A number of spheres were clustered around a single central sphere, and it’s the arrangement of the cluster that is used to represent a state—the dimples help keep the spheres stable once in place. In their lab, the researchers created a single entity consisting of four spheres clustered around a single sphere on the scale of approximately 5 µm—representing the most basic state, one capable of representing either a “0” or a “1”, i.e. a digital colloid. The team notes that capacity could be increased by increasing the size of clusters. Such clusters, the team suggests represent the possibility of small amounts of liquid holding very large amounts of information—a terabyte of data in just a single tablespoon, for example.The whole idea is still in its infancy, and the team has not yet worked out a way to read the clusters, though they suggest data could be stored by making use of materials to construct the spheres in such a way as to allow for changing the size of the central sphere on demand, thereby changing cluster shape. The group suggests digital colloids might be useful in soft robotics or perhaps they may add to the variety of ways large amounts of data are stored in very small ways in the future.

New technology to help prevent rhino poaching

Journal information: Journal of Applied Ecology Citation: New technology to help prevent rhino poaching (2015, July 21) retrieved 18 August 2019 from https://phys.org/news/2015-07-technology-rhino-poaching.html South Africa rhino poaching at new record levels A new group of technologies packaged together and called Rapid (Real-Time Anti-Poaching Intelligence Device) by its makers is on track to reduce poaching of rhinos, primarily in South Africa. The system was invented by British scientist Paul O’Donoghue—he and fellow scientist Christian Rutz, both of the University of St. Andrews have published an article in the Journal of Applied Ecology, describing the current state of poaching in Africa and how the new device might put a stop to it.center_img The system consists of a camera that can be embedded in a rhino’s horn and a heart monitoring device that is connected to an alarm system and GPS tracking unit. The heart monitor would go off, the authors report, if the rhino was approached by poachers—that would set off an alarm that would be sent directly to a team of armed conservationists who would jump into a helicopter and rush to the scene. If they are too late to stop the killing, they would at least be able to catch the poachers in the act, and hopefully retrieve evidence of the crime from the camera. Because of the fast response time, it would make poaching an extremely dangerous proposition. They note that extensive testing has been done with placement of the camera in the horn, which requires drilling—they insist that the rhinos experience no pain during the procedure.Rhinos are in serious danger—there are only about 25,000 of them left in the wild, the majority of which live in South Africa. Officials there have reported that approximately 1000 of the animals are killed every year, primarily for their horn, which some Asian cultures value very highly. It is believed that if the poaching is not halted, rhinos will cease to exist in the wild as soon as 2035. To protect the rhinos with the new device, rangers would have to catch each one, install the system and then release the animals back into the wild. O’Donoghue and Rutz believe their system can be adapted for use with other animals, such as tigers and elephants, two other animals that are being poached so heavily that they too may become extinct if something is not done to reverse the practice. Humane Society International is helping to fund the project. Explore further © 2015 Phys.org. All rights reserved.last_img read more

Ancient skeleton covered in cannabis shroud unearthed in China

first_img Humans have a long history of using cannabis for a variety of purposes—as hemp, it has been used to make rope and clothes; its seeds have been consumed to gain nutrition from the oils they contain, but perhaps most notoriously, the plant has been burned or eaten to gain a feeling of euphoria. In this new find, it appears the plant may have been used as part of a burial ritual.The skeleton has been identified as once belonging to a Caucasian man approximately 35 years old at the time of his death. Those that had buried him had placed a willow pillow under his head and had then placed a shroud of (13) cannabis plants over his chest reaching from below his pelvis at one end to the side of his face on the other. The skeleton lay in one of the 240 graves in the area known as the Jiayi cemetery. The people that lived in the area at the time were part of a Kingdom from 3,000 and 2,000 years ago known as the Subeixi. Prior research has shown the people lived there because it was an oasis in the desert, one that had become an important place for travelers to rest during their trek along the Silk Road.The researchers note that other examples of cannabis use have been found in the other nearby graves, but not as shrouds—mainly they were simply seeds or just leaves tossed into a grave site before burial. They point out that their find is the first to have full cannabis plants and the first time it has ever been seen used as a shroud. They believe the inclusion of whole plants suggests that the plants were grown locally—also the ripeness of the heads suggested they had been harvested and buried in the latter part of the summer. And because the heads were covered in glandular trichomes, which contain THC, the active ingredient in such plants, they believe that it was normally used as a psychoactive drug.

In their paper published in the journal Economic Botany, the team describes how they were continuing work on exploring an ancient cemetery looking for clues about early cannabis use and happened upon the unusual find.center_img More information: Hongen Jiang et al. Ancient Cannabis Burial Shroud in a Central Eurasian Cemetery, Economic Botany (2016). DOI: 10.1007/s12231-016-9351-1AbstractAn extraordinary cache of ancient, well-preserved Cannabis plant remains was recently discovered in a tomb in the Jiayi cemetery of Turpan, NW China. Radiometric dating of this tomb and the archeobotanical remains it contained indicate that they are approximately 2800–2400 years old. Both morphological and anatomical features support the identification of the plant remains as Cannabis. Research discussed in this paper describes 13 nearly whole plants of Cannabis that appear to have been locally produced and purposefully arranged and used as a burial shroud which was placed upon a male corpse. This unique discovery provides new insight into the ritualistic use of Cannabis in prehistoric Central Eurasia. Furthermore, the fragmented infructescences of Cannabis discovered in other tombs of the Jiayi cemetery, together with similar Cannabis remains recovered from coeval tombs in the ancient Turpan cemetery along with those found in the Altai Mountains region, reveal that Cannabis was used by the local Central Eurasian people for ritual and/or medicinal purposes in the first millennium before the Christian era.via National Geographic Explore further This document is subject to copyright.

Akhilesh Yadav accuses BJP of vitiating atmosphere of UP

first_img‘I have no hitch in saying that BJP and people of its ideology have vitiated atmosphere of the state. This ideology can be anywhere be it offices or police stations. It can be at any level but police officers have countered it by taking important decisions,’ Yadav said.He was addressing a gathering after inaugurating 100 newly constructed police houses at his official 5 Kalidas Marg residence here.Praising state police, Yadav said, ‘They (BJP) are fighting for loudspeakers. Fight is on to decide where and what should be constructed. Issue of love jihad was raised in a big way but police has controlled the situation. These incidents were taken cognisance by media but there are many such incidents, which they did not know and police has controlled the situation.’Attacking media for negative coverage, Yadav said that they had defamed the state government a lot especially in Badaun case.‘When DGP wanted to disclose the reality, a majority of journalists did not want to hear it. It’s not important for us what is running in the news (channels), but who is behind it,’ Yadav said.‘Media has sent us to UN. Such a free advertisement, Samajwadi party and its government never got in the past. Many times you (journalists) damage a lot due to your own personal interests. I am the only CM, who was shown most by news channels on the issue of law and order,’ he said.Cabinet minister Shivpal Yadav said that in the present regime there is no political interference on police and they have been given a free hand.last_img read more

The fabric of our times

first_imgKhadi is not just a fabric in India. It’s a way of life. The image of Gandhi sitting in front of a charkha acquired the weight of historical symbolism. Although Khadi will forever be associated with Mahatma Gandi and India’s independence movement, it is no longer regarded as the poor man’s cloth. Khadi (meaning, handspun and handwoven) cloth has taken on a new lease of life in recent years thanks to the new generation fashion designers who are applying innovative design techniques and turning khadi into a modern day style statement.
