Issues of organizing computations in multicomputer systems with the software-controlled failure- and fault-tolerance. Part III

This three-part paper analyzes existing approaches and methods of organizing failure- and fault-tolerant computing in distributed multicomputer systems (DMCS), identifies and provides rationale for a list of issues to be solved. We review the application areas of failure- and fault- tolerant control systems for complex network and distributed objects. The third part proceeds with the study of the problems of organizing failure- and fault-tolerant computing in distributed multicomputer systems (DMCS), carried out in parts I and II of this work, and deals with the issues related to the diagnosis of multiple faults. The paper describes the main differences in ensuring fault tolerance in systems with broadcast communication channels and point-to-point communication channels.

DiRong1.0: a distributed implementation for improving routing network generation in model coupling

A fundamental functionality of model coupling in an Earth system model is to efficiently handle data transfer between component models. An approach of M×N communication following a routing network has been used widely used for data transfer, and routing network generation becomes a major step required to initialize data transfer functionality. Some existing coupling software such as the Model Coupling Toolkit (MCT) and the existing versions of the Community Coupler (C-Coupler) employ a global implementation of routing network generation that relies on gather–broadcast communications, which can be very inefficient under a case of a large number of processes. This is an important reason why the initialization cost of a coupler increases with the number of processor cores. In this paper, we propose a “distributed implementation for routing network generation, version 1.0” (DiRong1.0), which does not introduce any gather–broadcast communication. Empirical evaluations show that DiRong1.0 is much more efficient than the global implementation. DiRong1.0 has already been implemented in C-Coupler2, and we believe that some other couplers can also benefit from it.

Program Fajar Indah Sebagai Media Dakwah dalam Meningkatkan Pemahaman Keagamaan Masyarakat

Penelitian ini bertujuan untuk mengetahui metode Program Fajar Indah yang ada di Radio Citra Progo dalam meningkatkan pemahaman keagamaan masyarakat, mengetahui klasifikasi da’i pengisi program Fajar Indah, serta pesan dakwah dari program Fajar Indah. Penelitian ini menggunakan penelitian kualitatif dengan metode deskriptif. Pengumpulan data dalam penelitian ini menggunakan teknik observasi, wawancara dan dokumentasi. Analisis data digunakan penafsiran logika yang dihubungkan dengan konteks Komunikasi Penyiaran Islam. Hasil penelitian menunjukan bahwa Radio Citra Progo dalam program Fajar Indah menggunakan metode ceramah dengan pembawaan da’i yang santai ketika siaran. Adapun klasifikasi da’i dalam siaran dakwah ini, dapat dilihat dari wawasan keilmuan penyiar dalam menguasai Al Quran dan Hadist sebagai sumber hukum Islam dan kedisiplinan untuk menjalankan tugas sebagai da’i penyiar radio. Dalam siaran Program Fajar Indah terdapat pesan dakwah berupa materi Aqidah untuk meningkatkan kepercayaan masyarakat kepada Allah, mengimani rukun Iman dan rukun Islam, serta materi Akhlak yang diperintahkan oleh Allah dan dicontohkan oleh Nabi Muhammad SAW, materi Ibadah yang menyampaikan tatacara beribadah kepada Allah meliputi hukum pernikahan, hukum bertetangga, shodaqoh, sholat, puasa dan menyampaikan materi tentang hari-hari besar umat Islam. This study aims to determine the methods of the Beautiful Fajar Program on Radio Citra Progo in improving people's religious understanding, knowing the classification of preachers for the Fajar Indah program, and preaching messages from the Fajar Indah program. This study uses qualitative research with descriptive methods. Data collection in this study uses observation, interview and documentation techniques. Data analysis used the interpretation of logic connected with the context of Islamic Broadcast Communication. The results showed that Citra Progo Radio in the Fajar Indah program used a lecture method with a relaxed nature when broadcasting. The da'i classification in this da'wah broadcast, can be seen from the broadcaster's scientific insights in mastering the Qur'an and Hadith as a source of Islamic law and discipline to carry out their duties as radio broadcast preachers. In the broadcast of the Fajar Indah Program there is a da'wah message in the form of Aqeedah material to increase public trust in God, faith in the pillars of faith and pillars of Islam, as well as moral material ordered by God and exemplified by the Prophet Muhammad, the material of worship which conveys the procedure of worship to God including marriage law , neighborly law, shodaqoh, prayer, fasting and delivering material about the Muslim holidays.

PENGELOLAAN ARSIP DINAMIS PADA FAKULTAS USHULUDDIN ADAB DAN DAKWAH (FUAD) IAIN BATUSANGKAR

The management of dynamic records becomes the reference of an organization to achieve the goals of the organization. Dynamic archives will not be separated from correspondence in each unit at the agency. The background of this research is that the archives of Ushuluddin Adab and Da'wah (FUAD) IAIN Batusangkar have not been maximized. The research that the author uses is descriptive research with a qualitative approach. There were 4 informants in this assessment consisting of 1 Head of Administration and 4 archiving officers in the Faculty environment, are a receptionist manager, 3 departmental employees namely 1 Department of Library and Islamic Science Department 1 employee, Islamic Broadcast Communication 1 people and employees majoring in Islamic Political Thought 1 person. Based on observations made by the author, it can be concluded that the management of dynamic archives at the Faculty of Usuluddin Adab and Da'wah (FUAD) of Batusangkar IAIN has not run optimally, for the management of incoming and outgoing letters such as official letters, student letters in their distribution require a long time especially when the receptionist was not in place because the receptionist was a lecturer employed. Staff limitations and the difficulty in re-finding archives are due to the management of archives that are not in accordance with the standards and inadequate supporting facilities. Archival shrinkage in the Faculty of Usuluddin Adab and Da'wah has not used the Archive Retention Schedule.
