دہر میں اسم محمد سے اُجالا کر د ے
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اسا تذہ کرام اور میرے ہم مکتب شاہینو!
آج مجھے جس موضوع پر اظہار خیال کرنا ہے وہ ہے: ’’دہر میں اسمِ مُحمَّدؐ سے اُجالا کردے‘‘
کی محمد سے وفا تو نے تو ہم تیرے ہیں
یہ جہاں چیز ہے کیا لوح و قلم تیرے ہیں
صدرِ ذی وقار!
ہم مسلمان ہیں، ہم کلمہ گو ہیں ، ہم اللہ اور رسولؐ پر ایمان رکھتے ہیں، ہم زباں سے بھی کہتے ہیں اور دل سے بھی تصدیق کرتے ہیں کہ اللہ ایک ہے اور محمدرسول اللہؐ اس کے آخری رسول ہیں۔
جنابِ صدر!
اس کے باوجود ہم پستی کا شکار کیوں ہیں ، ہماری صفوں میں اتحاد کیوں نہیں ہے، ہم متحد کیوں نہیں ہیں، ہماری زندگی میں عروج کیوں نہیں ہے، ہماری حیات پستی کی طرف کیوں مائل ہے۔
جنابِ صدر!
اس کا سبب یہ ہے کہ ہمارا اعتقاد صرف زبان کی حد تک رہ گیا ہے، ہماری محبت صرف زبانی ہے، ہمارا انس صرف عارضی ہے، ہمارا پیارصرف جزوقتی ہے۔ ہم نام کے مسلمان ہیں ہمارا ظاہر اور باطن یکسانیت کا مظہر نہیں ہے۔
جنابِ صدر!
اگر ہم چاہتے ہیں کہ اقوام عالم میں ہمارا نام ہو، ہماری دنیوی و اُخروی زندگی بہتر ہو، ہم معاشرتی لحاظ سے پسماندگی کا شکار نہ ہوں تو محمد رسول اللہؐ سے اپنی محبت کے معیار کو بلند کرنا ہوگا، رسول اللہؐ کی سنتوں پر عمل کرنا ہو گا، اسی سے ہم پستی سے نکل کر بلندی پرپہنچ سکتے ہیں۔
قوت عشق سے ہر پست کو بالا کر دے
دہر میں اسمِ محمد سے اجالا کر دے
والسلام
The Holy Prophet a made several treaties to create a Peaceful state and good neighborly relations with neighboring tribes and Counteries of the Islamic State. He also held peace treaties, which are beneficial to the Muslims in particular and humanity in general. These treaties are effective means of ensuring peace and security and to strengthen the provision of human rights. This study is to highlight the humanitarian dimensions of the treaties of the Prophet to be an invitation aimed at consolidating human values and lay theories of tolerance for coexistence cream among the various nations of the contemporary world, cutting the road on the theories of clash between civilizations to disrupt the harmony and world peace
Large-scale network simulations are resource and time intensive tasks due to a number of factors i.e., setup configuration, computation time, hardware, and energy cost. These factors ultimately force network researchers to scale-down the scope of experiments, either in terms of Simulation Entities (SEs) involved or in abridging expected micro-level details. The Cloud technology facilitates researchers to address mentioned factors by the provisioning of Cloud instances on shared infrastructure. In this thesis, an academic Cloud SIM-Cumulus targeting the research institutions is proposed. The thesis is divided into three parts, each part discussing the contributions achieved in thesis. The first part of this thesis discusses the design and implementation of SIMCumulus academic Cloud framework for the provisioning of Network-Simulationas-a-Service (NSaaS). SIM-Cumulus provides the framework of Virtual Machine (VM) instances specifically configured for large-scale network simulations, with the aim of efficiency in terms of simulation execution time. The performance of SIM-Cumulus is evaluated using large-scale Wireless Network simulations that are executed sequentially as well as in parallel. Simulation results show that SIM-Cumulus is beneficial in two aspects i.e., (i) promotion of research within the domain of computer networks through configured Cloud instances of network simulators (ii) consumption of considerably fewer resources in terms of simulation elapsed time and usage cost. The execution of simulation in parallel involves the partitioning of simulation model into several components and each component is assigned to separate execution units (Logical Processes (LPs)). Each LP is comprised of a set of SEs that can interact with local as well as remote SEs. However, the remote communication among SEs and synchronization management across LPs are the two main issues related to the parallel and distributed executions of large-scale simulations. A number of migration techniques are used to mitigate the problem of high remote communication and lead to a reduction in remote communication among SEs. However, most of the existing migration strategies result in higher number of migration which lead to higher computation overhead. The second part of the thesis contributes Migration-based Adaptive Heuristic Algorithm (known as MAHA). MAHA provides dynamic partitioning of the simulation model based on runtime dynamics of the wireless network simulations. The proposed algorithm uses an intelligent heuristic for migration decision in order to reduce the number of migrations with an ultimate goal to achieve better Local Communication Ratio (LCR). The proposed algorithm is better in terms of achieving improved LCR with reduced number of migrations as compared to the existing technique(s). The third contribution of this thesis is related to implementation of adaptive SIM-Cumulus (A-SIM-Cumulus) that integrates Advanced Runtime Infrastructure System (ARTIS) and Generic Adaptive Interaction Architecture (GAIA) with the SIM-Cumulus framework. To obtain an insight into the performance gain, the simulation has been performed multiple times with different configurations and execution environments. The obtained results assert that the proposed algorithm significantly reduces the number of migrations and achieves a good speedup in terms of execution time for parallel (i.e., both multi-core and distributed) simulations on the A-SIM-Cumulus Cloud.
