1. 1. Parallelising High OrderTransform of Point SpreadFunction and TemplateSubtraction for AstronomicImage Subtraction : The implementation of BACH

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Annie Wång; Victor Lells; [2023]
   Nyckelord :Image Subtraction; HOTPANTS; SFFT; GPU; Parallelisation;

   Sammanfattning : This thesis explores possible improvements, using parallel computing, to the PSF-alignment and image subtraction algorithm found in HOTPANTS. In time-domain astronomy the PSF-alignment and image subtraction algorithm OIS is used to identify transient events. LÄS MER

3. 2. A Conjugate Residual Solver with Kernel Fusion for massive MIMO Detection

   Master-uppsats, Högskolan i Halmstad/Centrum för forskning om tillämpade intelligenta system (CAISR)

   Författare :Ioannis Broumas; [2023]
   Nyckelord :MIMO; massive MIMO; GPU; CUDA; Software Defined Radio; SDR; MMSE; ZF; zero-forcing; parallel detection; iterative methods; conjugate residual; parallel computing; kernel fusion;

   Sammanfattning : This thesis presents a comparison of a GPU implementation of the Conjugate Residual method as a sequence of generic library kernels against implementations ofthe method with custom kernels to expose the performance gains of a keyoptimization strategy, kernel fusion, for memory-bound operations which is to makeefficient reuse of the processed data. For massive MIMO the iterative solver is to be employed at the linear detection stageto overcome the computational bottleneck of the matrix inversion required in theequalization process, which is 𝒪(𝑛3) for direct solvers.

4. 3. Real-time Soft Body Simulation using Extended Position-Based Dynamics and Tetrahedral Deformation

   Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :William Kamnert; [2023]
   Nyckelord :Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

   Sammanfattning : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. LÄS MER

5. 4. Evaluation of FPGA-based High Performance Computing Platforms

   Master-uppsats, Linköpings universitet/Datorteknik

   Författare :Martin Frick-Lundgren; [2023]

   Sammanfattning : The General-Purpose GPU (GPGPU) has emerged as the predominant computing device for extensive parallel workloads in the fields of Artificial Intelligence (AI) and Scientific Computing, primarily owing to its adoption of the Single Instruction Multiple Thread architecture, which not only provides a wealth of thread context but also effectively hide the latencies exposed in the single threads executions. As computational demands have evolved, modern GPGPUs have incorporated specialized matrix engines, e. LÄS MER
