Efficient Implementation of 3D Finite Difference Schemes on Recent Processors Abstract In this paper a solver is introduced that solves a problem set modelled by the Burgers equation using the finite difference method: forward in time and central in space. The solver is parallelized and optimized for Intel Xeon Phi 7120P as well as Intel Xeon E5-2699v3 processors to investigate differences in terms of performance between the two architectures. Optimized data access and layout have been implemented to ensure good cache utilization. Loop tiling strategies are used to adjust data access with respect to the L2 cache size. Compiler hints describing aligned memory access are used to support vectorization on both processors. Additionally, prefetching strategies and streaming stores have been evaluated for the Intel Xeon Phi. Parallelization was done using OpenMP and MPI. The parallelisation for native execution on Xeon Phi is based on OpenMP and yielded a raw performance of nearly 100 GFLOP/s, reaching a speedup of almost 50 at a 83\% parallel efficiency. An OpenMP implementation on the E5-2699v3 (Haswell) processors produced up to 292 GFLOP/s, reaching a speedup of almost 31 at a 85\% parallel efficiency. For comparison a mixed implementation using interleaved communications with computations reached 267 GFLOP/s at a speedup of 28 with a 87\% parallel efficiency. Running a pure MPI implementation on the PDC's Beskow supercomputer with 16 nodes yielded a total performance of 1450 GFLOP/s and for a larger problem set it yielded a total of 2325 GFLOP/s, reaching a speedup and parallel efficiency at resp. 170 and 33,3\% and 290 and 56\%. An analysis based on the roofline performance model shows that the computations were memory bound to the L2 cache bandwidth, suggesting good L2 cache utilization for both the Haswell and the Xeon Phi's architectures. Xeon Phi performance can probably be improved by also using MPI. Keeping technological progress for computational cores in the Haswell processor in mind for the comparison, both processors perform well. Improving the stencil computations to a more compiler friendly form might improve performance more, as the compiler can possibly optimize more for the target platform. The experiments on the Cray system Beskow showed an increased efficiency from 33,3\% to 56\% for the larger problem, illustrating good weak scaling. This suggests that problem sizes should increase accordingly for larger number of nodes in order to achieve high efficiency. Frederick Ceder / Effektiv implementering av finita differensmetoder i 3D på moderna processorarkitekturer Sammanfattning Denna uppsats diskuterar implementationen av ett program som kan lösa problem modellerade efter Burgers ekvation numeriskt. Programmet är byggt ifrån grunden och använder sig av finita differensmetoder och applicerar FTCS metoden (Forward in Time Central in Space). Implementationen paralleliseras och optimeras på Intel Xeon Phi 7120P Coprocessor och Intel Xeon E5-2699v3 processorn för att undersöka skillnader i prestanda mellan de två modellerna. Vi optimerade programmet med omtanke på dataåtkomst och minneslayout för att få bra cacheutnyttjande. Loopblockningsstrategier används också för att dela upp arbetsminnet i mindre delar för att begränsa delarna i L2 cacheminnet. För att utnyttja vektorisering till fullo så används kompilatordirektiv som beskriver minnesåtkomsten, vilket ska hjälpa kompilatorn att förstå vilka dataaccesser som är alignade. Vi implementerade också prefetching strategier och streaming stores på Xeon Phi och disskuterar deras värde. Paralleliseringen gjordes med OpenMP och MPI. Parallelliseringen för Xeon Phi:en är baserad på bara OpenMP och exekverades direkt på chipet. Detta gav en rå prestanda på nästan 100 GFLOP/s och nådde en speedup på 50 med en 83% effektivitet. En OpenMP implementation på E5-2699v3 (Haswell) processorn fick upp till 292 GFLOP/s och nådde en speedup på 31 med en effektivitet på 85%. I jämnförelse fick en hybrid implementation 267 GFLOP/s och nådde en speedup på 28 med en effektivitet på 87%. En ren MPI implementation på PDC's Beskow superdator med 16 noder gav en total prestanda på 1450 GFLOP/s och för en större problemställning gav det totalt 2325 GFLOP/s, med speedup och effektivitet på respektive 170 och 33% och 290 och 56%. En analys baserad på roofline modellen visade att beräkningarna var minnesbudna till L2 cache bandbredden, vilket tyder på bra L2-cache användning för både Haswell och Xeon Phi:s arkitekturer. Xeon Phis prestanda kan förmodligen förbättras genom att även använda MPI. Håller man i åtanke de tekniska framstegen när det gäller beräkningskärnor på de senaste åren, så preseterar både arkitekturer bra. Beräkningskärnan av implementationen kan förmodligen anpassas till en mer kompilatorvänlig variant, vilket eventuellt kan leda till mer optimeringar av kompilatorn för respektive plattform. Experimenten på Cray-systemet Beskow visade en ökad effektivitet från 33,3% till 56% för större problemställningar, vilket visar tecken på bra weak scaling. Detta tyder på att effektivitet kan uppehållas om problemställningen växer med fler antal beräkningsnoder. Frederick Ceder

Le concile de Troyes qui s'ouvre le 13 janvier 1129, permet de confirmer une initiative née en Orient neuf années auparavant. Des chevaliers avaient alors exprimé la volonté de vivre de façon religieuse, en faisant le triple vœu monastique de pauvreté, de chasteté et d'obéissance, tout en continuant à pratiquer le métier des armes afin de protéger les pèlerins sur les routes de Terre sainte. Reconnus par la papauté à Troyes et dotés d'une règle, les « pauvres chevaliers du Christ et du Temple de Salomon » devenaient le premier ordre religieux-militaire de l'histoire. L'ordre de l'Hôpital, qui existait déjà à Jérusalem et dont la mission consistait à soigner les pauvres malades, se militarisa progressivement au milieu du XIIe siècle, s'inspirant de l'exemple du Temple. Templiers et Hospitaliers ont inspiré par la suite tous les autres ordres militaires. Une tradition historiographique des croisades a longtemps entretenu l'idée de deux ordres ennemis dont les conflits ont provoqué la perte des États latins d'Orient. L'étude de deux siècles de coexistence commune entre Templiers et Hospitaliers en Terre sainte permet d'enterrer cette image et constater combien ces deux ordres religieux-militaires se sont influencés. Elle permet également de rétablir la vérité sur les relations entre les frères des deux ordres. Aux frontières de l'histoire comparée, cette étude suit la trame chronologique des maîtres du Temple et de l'Hôpital, permettant de mettre en relief l'importance des décisions de ces hommes. Des études thématiques sur l'organisation de ces deux ordres, leurs structures, leurs règles, les images qu'ils transmettent et sur leur rôle dans certains grands évènements des États latins d'orient permet de comprendre les liens qui les unissaient, ainsi que la façon dont ils s'influencèrent. On a trop souvent relevé leur rivalité politique, dans un royaume de Jérusalem où l'absence d'un pouvoir royal fort leur a rapidement laissé toute liberté. De la même façon, on a trop souvent oublié le prix que Templiers et Hospitaliers ont payé ensemble sur les champs de bataille de Terre sainte, se comportant comme ce qu'ils étaient : des frères d'armes. / The Council of Troyes, wich opened on January 13, 1129, confirms an initiative born in the East nine years earlier. Knights had then expressed the will to live in a religious way, by making the triple monastic vow of poverty, chastity and obedience, while continuing to practice the profession of arms in order to protect pilgrims on the roads of the Holy Land. Recognized by the papacy in Troyes and endowed with a rule, the « Poor Knights of Christ and of the Temple of Solomon » became the first military order in history. The Order of the Hospital, which already existed in Jerusalem and whose missions was to care for the poor sick, gradually became militarized in the middle of the 12th century, drawing inspiration from the example of the Temple. Templars and Hospitallers subsequently inspired all other military orders. A historiographical tradition of the Crusades has long maintained the idea of two enemy orders whose conflicts caused the loss of the Latin States of the East. The study of two centuries of common coexistence between Templars and Hospitallers in the Holy Land allows us to bury this image and see how much these military orders influenced each other. It aslo helps to restore the truth about the relationship between the brothers of the two orders. At the frontiers of comparative history, this study follows the chronological framework of the masters of the Temple and the Hospital, making it possible to highlight the importance of the decisions of these men. Thematic studies on the organization of these two orders, their structures, their rules, the images that they transmit and their role in some great events of the Latin States of the East make it possible to understand the links wich united them, as well as the how they influenced each other. We have too often noted their political rivalry, in a kingdom of Jerusalem where the absence of a strong royal power quickly gave them complete freedom. In the same way, we have too often forgotten the price that Templars and Hospitallers paid together on the battlefields of the Holy Land, behaving like what they were : brothers in arms.

From Ancient Near Eastern texts, the Bible and archaeological artefacts, we are able to glimpse an over arching belief in a feminine deity. During the occupation of the Temple Mount by the Knights Templars, earlier traditions were ”re-discovered” and accepted as a de facto tradition. William St Clair at the threshold of the Renaissance, mindful of the danger of heresy, was intellectually able to bring together many traditions into a broad Biblically-based theology that recognised the early Israelite traditions as the foundation of Christian belief. All this is evident in Rosslyn Chapel. / OLD TESTAMENT & ANCIENT NE / MA (BIBLICAL ARCHAEOLOGY)

Beata Maria/Dea Vults is a thesis for the degree of master (one year) in theology.   The thesis explores the role of the Virgin Mary as a martial saint in catholic combat with Islam and muslims between the years 1119 AD to 1648 AD with a focus on symbolism. The paper is focusing on symbolism in war banners, patron saints and semiotic symbols on arms and armour. There are three different events or phenomenons in the study, separated in time as well as space.   Firstly the war banner used at the battle of Las Navas (1212 AD) during the reconquista of Spain. The banner of Mary with child is the prime subjekt as well as the myths appearing in the aftermath of the battle, and the ceremony that was devised from it.   The second phenomenon is the knights templars use of Mary as patron saint, and the ceremony that followed this relationship. There is also discussion of the belts worn that were related to Mary, the use of wich is attested in documents from the trials of the templars between 1307 and 1312 AD. Lastly the paper focuses on the armours of the polish winged husars of 1648 AD and the seige of Vienna. The thesis explores the relationship between the symbols of the armour of the husars and the religious views of King John III Sobieski of Poland.   The main question of the study is:   What were the meaning of the symbols of Mary as she was carried as a ritualistic symbol for war?   The subsequent questions are:   How do you trace a progression in the useage of Mary as a symbol from the templars all the way to the use of Mary as a symbol for the winged husars?   Which types of worship of Mary as a symbol were used primarliy in wars with muslims?   The paper is researched by qualitative methods including text analysis as well as semiotic symbolism reading. There are two theories used in the analysis. Smarts dimensions and Andersons and Hulls Warrior elites, with Smarts dimensions as the dominant theory.

This paper examines Wolfram von Eschenbach’s juxtaposition of contrary things in Parzival as the beginning of the road to spiritual salvation for Parzival. Men’s quest for fame and honor in the material, Arthurian world is compared to the divine Grail kingdom and the godlike women who shed compassionate, Christ-like tears. Wolfram’s message of peace and love for brother is examined through his use of symbolism, particularly through womens’ tears and turtledove imagery. Parzival, Gâwân and Feirefiz are compared in order to show that the love and quest for personal honor in the Arthurian world is a necessary step on the path to God’s divine love and salvation. Compassion and love for one’s neighbor must be learned before Parzival attains his destiny. How marriage teaches Parzival triuwe and how he demonstrates this characteristic are examined. Romantic love, emulation of women and divine love lead Parzival to his destiny.
