Vectorization with Haswell and CilkPlus
No full textProject Specification:
This project concerns the parallel computing and vectorization field for Physics Computing at CERN. The document summarises the results and experience from vectorization activities and an initial evaluation of the CilkPlus technology with two different benchmarks from CERN.
Abstract:
With the release of the Intel Sandy Bridge processor, vectorization ceased to be a “nice to have” feature and became a necessity. This work is focused on optimization, running comparative measurements of available vectorization technologies currently under investigation by the CERN Concurrency Forum. In particular, the project involves an assessment of the limits of autovectorization in two compilers, an evaluation of CilkPlus as implemented in ICC/GCC and an evaluation of AVX/AVX2 benefits with respect to legacy SSE workloads

Juliusz Nowak-Dłużewski's School. Historical-Literary Connections
No full textJuliusz Nowak-Dłużewski (31.03.1893, Goszcza – 19.04.1972, Warszawa), a literary scholar and historian, a teacher in secondary schools in Kielce and Warszawa. He did Polish Studies and his PhD in 1932 at the Jagiellonian University in the care of his promoter, Professor Ignacy Chrzanowski. During World War II he lectured at Kielce branch of Polish Studies of University of Western Lands. After the war he habilitated in Toruń on the basis of his monograph dedicated to priest Stanisław Konarski, afterwards, he took a job as a substitute for a Professor at Catholic University of Lublin and as an associate professor at University of Warsaw. His teaching and pedagogic service bore fruit in 1938 in the form of the Gold Cross of Merits. Post-war frameworks of reconstruction and the effort of the preservation from destruction of post-courtly collections from the position of the director of the National Museum in Kielce resulted in the Order of Polonia Restituta (1963). Finally, Nowak-Dłużewski’s research and development works met with recognition from the jury of the Włodzimierz Pietrzak Literary Award two times (1964, 1967).
The memoir dedicated to Professor J. Nowak-Dłużewski develops from his student’s conviction about the perfection of his didactic and educational mission performed by him with devotion during the difficult times when Communism was on the rampage. We experienced Professor’s special care and foresight in the last decade of his life (1962-1972), when he resolved to “remake us into angels” by destining us for creative work in conditions close to monastic closure – in the team of a PhD seminary. A doubtless protagonist of the given text is our Master, Professor Juliusz Nowak-Dłużewski. For this reason, the references include only articles and utterances of particular people with the intention of underlining our interpersonal master-pupils bond. To my mind, this aspect appears to excuse the author in the eyes of Colleagues as well as Readers
Leszek Nowak – obituary
No full textOn 20th of October 2009 died Leszek Nowak, one of the most creative and original Polish philosophers. Born on 7th of January 1943, Nowak studied law (Adam Mickiewicz University, Poznań) and philosophy (Warsaw University). He lived to philosophize. It is not a conventional phrase but the true description of his activities. He devoted his live to philosophy. He got professor’s title in 1976, at the age of 33. At that time he was the youngest professor in Poland and the author of the methodological conception – the idealizational theory of science. His theory was inspired by ideas he found in Marx’s writings. He made them explicit and precise by using the language of contemporary logical philosophy. The result was the theory that offered a new, detailed and systematic picture of science [10], [18]. Leszek Nowak admired Marx’s ideas and planned to reconstruct Marx’s entire philosophical system. It soon occurred to him that Marx’s social philosophy was unable to account for the functioning of the societies of so-called real socialism. Nowak retained Marx’s materialism but rejected the narrow, economic view of society. In 1977 he started to work on a new, generalized social theory, which he called the non-Marxian historical materialism [12]. In this theory real socialism occurs as the most oppressive system in the history of the hitherto known societies. One has to be bold or naïve to work on such a theory in the country of real socialism. Leszek Nowak was aware of the risk but he did not decide to accept intellectual compromise and in 1979 disseminated the typescript of his book on real socialism. During the time of Solidarność movement he spent all energy to educate union members and to reveal the oppressive nature of socialism. He was interned on 13th of December 1981 and spent a year in jail. In 1985 he was expelled from the university and in 1989 his professorship was reinstated. Extremely hard work, engagement in the Solidarność movement, and protests during internment seriously undermined his health. In the last years Leszek Nowak was not able to teach but he painstakingly worked on his new love – metaphysics. Results of his research were published in Polish in three volumes [16], [19], [20]. In our view his conception represents a non-standard approach to metaphysical problems. In Polish philosophy Nowak’s metaphysics can be only confronted with Roman Ingarden’s The controversy over the existence of the world. It is our firm conviction that Leszek Nowak’s place in Polish philosophy in the second half of the twentieth century is defined by the following qualities: a bold search for new and original idea, laborious work to present it in a systematic way, readiness to defend it against petrifying tendencies be they scientific, political, religious or ideological
Tree cover is unevenly distributed across cities globally, with lowest levels near highway pollution sources
No full textObtaining accurate tree cover maps within cities is a first step toward managing for equitable access to their ecosystem services. For example, by removing air pollutants trees contribute to fewer health impacts, and tree cover expansion could extend these benefits by targeting the most polluted areas and vulnerable populations. To support strategic tree expansion, this research created urban tree cover maps using the 2017 NASA MOD44B satellite 250 m pixel product for 35 megacities, areas with large levels of pollution and vulnerable populations. Estimates of tree cover from photo-interpretation (PI) were used to characterize map error, city-wide, and from low to high tree cover, using 21 bins from 0 to 100% tree cover. Map accuracy was highest when MOD44B percent tree cover was combined with its tree cover standard deviation product, with average difference of 1.8% compared with PI estimates of 19.9% city-wide tree cover. MOD44B estimates of tree cover spatial patterns had strong explanatory value. The maps explained the PI estimates of low to high tree cover at 5% tree cover intervals with an R2 = 0.97. The Getis Ord Gi* statistic determined a non-random spatial distribution of tree cover within the megacities, with significant clustering into hot spots of relatively high tree cover and cold spots of relatively low tree cover. Tree cover hot spots were most often furthest from downtown, at the rural-urban interface or within higher elevation terrain. Tree cover cold spots were most often in areas of concentrated development and along traffic corridors known for high levels of particulate matter and other air pollutants that could be reduced by trees. Given small increases in exposure to particulate matter are associated with significant increases in death rates from viruses, and that climate change and associated heat waves are forecast to exacerbate health risks to air pollution, we need to improve global urban tree cover. These map products can be used to expand tree cover that strategically contributes to pollutant abatement, human well-being, and sustainable cities
Impact of antidepressant drugs on sexual function and satisfaction
No full textPleasurable sexual activity is important in many human relationships and can provide a sense of physical, emotional and social well-being. Depressive symptoms and depressive illness are associated with impairments in sexual function and sexual dissatisfaction in untreated and treated patients. Most currently available antidepressant drugs are associated with development or worsening of sexual dysfunction in a substantial proportion of patients. Sexual difficulties during antidepressant treatment often resolve as depression lifts, but can persist over long periods, reducing self-esteem and affecting mood and relationships adversely. Sexual difficulties during antidepressant treatment typically have many possible causes but the incidence and nature of dysfunction varies between drugs. Many interventions can be considered when managing sexual dysfunction associated with antidepressants but no approach is ‘ideal’. Because treatment-emergent sexual difficulties are less frequent with certain drugs, presumably related to differences in pharmacological properties, and since current interventions are suboptimal, a lower incidence of sexual dysfunction is a relevant tolerability target when developing novel antidepressant
Juliusz Nowak-Dłużewski's School. Historical-Literary Connections
No full textJuliusz Nowak-Dłużewski (31 III 1893 - 19 IV 1972), historyk literatury, absolwent filologii polskiej Uniwersytetu Jagiellońskiego, uczeń i doktorant prof. Ignacego Chrzanowskiego, nauczyciel Gimnazjum Jana Zamoyskiego w Warszawie, a podczas II wojny światowej organizator i wykładowca filii kieleckiej Tajnego Uniwersytetu Ziem Zachodnich – po pięknych zasługach w powojennym ratowaniu bibliotek dworskich i dzieł sztuki współtworzył Muzeum Świętokrzyskie i Bibliotekę Wojewódzką w Kielcach. W 1951 r. habilitował się u prof. Konrada Górskiego w Toruniu, obejmując stanowisko zastępcy profesora KUL, a następnie od roku akad. 1956/57 – profesora nadzwyczajnego Uniwersytetu Warszawskiego. W stolicy witali go bardzo serdecznie dawni jego uczniowie. „Kochał bardzo młodzież i dobrze ją rozumiał” – napisze potem z oddali emigracyjnej prof. Wiesław Strzałkowski, żołnierz PSZ na Zachodzie, lecz przede wszystkim poeta, z nabożeństwem dedykujący Profesorowi własne wiersze. W 1962 roku, gdy Nowak-Dłużewski, powołując seminarium doktoranckie, podjął „świętą wojnę” z ostracyzmem komunistycznym, garnęli się doń przybysze z całego kraju. Gdyby nie przyjął pomocy Instytutu Wydawniczego „PAX” ze strony przedwojennych uczniów, byłby jako badacz narażony na intelektualny niebyt. Dwukrotnie wzmocniły go Nagrody im. Włodzimierza Pietrzaka (1964, 1967). Czytelnikom dał się poznać odkrywczym opus vitae, 6-tomową syntezą „Okolicznościowa poezja polityczna w Polsce” (1963-1980). Wychował grono doktorów, ucząc ich wiary i nadziei, a także odporności na ciśnienie obcej ideologii. O tych niełatwych latach – i o wspólnym zwycięstwie – pisze jeden z nich.Juliusz Nowak-Dłużewski (31.03.1893, Goszcza – 19.04.1972, Warszawa), a literary scholar and historian, a teacher in secondary schools in Kielce and Warszawa.
