| Abstract | A recent experiment at Rand has provided quantitative data on the effect of using different languages for simulating computer systems. The experiment consisted of programming a small simulation of a hypothetical multiprogrammed computer in ECSS (the Extendable Computer System Simulator), a new experimental language specifically oriented toward simulating computer systems, and recording in detail the progress of program development. The purpose of the experiment was to determine to what extent the prototype version of ECSS could reduce the time and expense of such simulation projects. This paper reviews the major elements of ECSS, describes the experimental procedure, and outlines the key features of the ECSS program produced. The results of using ECSS are then compared to the results using FORTRAN and PL/I for the same task. A factor of three reduction in programming time and a factor of two reduction in machine time for model development using ECSS were obtained, but the number of statements required was not significantly reduced, more errors were made, and object program size was much larger for the ECSS version. Although suggestive, a number of experimental difficulties were found to limit the generality of the results. The paper concludes with a discussion of how these results have affected ECSS development, some suggestions for others attempting to evaluate languages for computer system simulation, and an assessment of the hazards and rewards of this empirical evaluation method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
