Item CSPR: Column only SPARSE matrix representation for performance improvement on GPU architecture(2011) Bayyapu, B.; Raghavendra, P.S.General purpose computation on graphics processing unit (GPU) is prominent in the high performance computing era of this time. Porting or accelerating the data parallel applications onto GPU gives the default performance improvement because of the increased computational units. Better performances can be seen if application specific fine tuning is done with respect to the architecture under consideration. One such very widely used computation intensive kernel is sparse matrix vector multiplication (SPMV) in sparse matrix based applications. Most of the existing data format representations of sparse matrix are developed with respect to the central processing unit (CPU) or multi cores. This paper gives a new format for sparse matrix representation with respect to graphics processor architecture that can give 2x to 5x performance improvement compared to CSR (compressed row format), 2x to 54x performance improvement with respect to COO (coordinate format) and 3x to 10 x improvement compared to CSR vector format for the class of application that fit for the proposed new format. It also gives 10% to 133% improvements in memory transfer (of only access information of sparse matrix) between CPU and GPU. This paper gives the details of the new format and its requirement with complete experimentation details and results of comparison. © 2011 Springer-Verlag.Item ESG Investment and Sustainability Reporting: A Systematic Review for Future Research(Springer Nature, 2023) Poornima, S.; Gopalakrishna, B.V.Sustainable finance is an area of study that looks beyond the simple number of risk and return. It looks over the impact of investment on ESG, i.e., environment, society, and governance factors. This paper conducts a comprehensive review of research works on ESG and its disclosures using the TCCM framework and thematic analysis, specifically in the Indian context, to determine future research priorities and research gaps in India. The search parameters identified 50 research papers, 44 of which were accepted for analysis. The study identified a gap in the available literature that allows for future observation. The study agenda in this review may help researchers to construct specific research fields around the discovered gaps. ESG investment has emerged as a critical problem for businesses. As a result, a considerable study in this sector is required to grow this topic as an operational investment area. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2023.Item ‘CSR, sustainability and firm performance linkage’ current status and future dimensions – a bibliometric review analysis(Inderscience Publishers, 2024) Sreepriya, J.; Suprabha, K.R.Corporate social responsibility (CSR) and sustainability are gaining worldwide recognition. The question of whether CSR and sustainability programs benefit an organisation’s financial success is still being debated. This study aims to verify this phenomenon by examining the current literature pattern on this relationship using bibliometric and systematic review analysis. It further provides a taxonomy for understanding this association. VOSviewer is used to obtain comprehensive dataset mapping and clustering in the field. The manuscript offers promising insights regarding academia by assessing the pattern of publication trends, the most influential author in the area, and analysing the methodological and theoretical underpinnings of CSR, sustainability and firm performance linkage. The outcome of this study provides exploratory insights into research gaps and avenues for future research. © © 2024 Inderscience Enterprises Ltd.
