130. Simulations of Rotating Newtonian Universes

Balázs Pál (Wigner Research Centre for Physics)

We present the results of a novel type of numerical simulation that realizes a rotating universe with a shear-free, rigid body rotation in a Gödel-like metric. We run cosmological simulations with various degrees of rotation and compare the results to the analytical expectations of the Einstein--de Sitter and the $\Lambda$CDM cosmologies. To achieve this, we use the StePS N-body code that is...

142. Parallel image reductions over polygon masks

In many image processing problems, we need to process polygons that usually involve rasterization. Also, in many such problems we need to compute reductions over images, such as average of intensities or other metrics. In some cases, a combination of the two computations is desired: we need to use the area of polygons to restrict which pixels should contribute to a reduction operation. Doing...

147. Tensor Core Computing: an example on Independent Component Analysis

Lecture

The tensor core is a hardware unit in most modern GPUs first introduced in the NVIDIA Volta architecture. Similarly to the well-known CUDA core (Streaming Processor, SP), the tensor core is also a computing unit of the Streaming Multiprocessor (SM), but the input data to the tensor cores are a set of matrixes rather than single values processed by the CUDA cores. Each Tensor Core provides a...

133. Monitoring ALICE Analysis Facility infrastructure: operation and visibility

We would like to present a short introduction to the ALICE Analysis Facility and WSCLAB (Wigner Scientific Computing Laboratory) projects in our datacenter and show some key operation and visibility details of monitoring. Hardware components are aging, so monitoring is an important method to keep infrastructure healthy and to prolong cluster lifetime.
We created server types (worker node,...
