Racing to Idle: Energy Efficiency of Matrix Multiplication on Heterogeneous CPU and GPU Architectures
The paradigm shift towards multi-core and heterogeneous computing, driven by the fundamental power and thermal limits of single-core processors, has established energy efficiency as a first-class design constraint in high-performance computing (HPC). Heterogeneous systems, integrating traditional multi-core CPUs with specialized accelerators like discrete (dGPU) and integrated (iGPU) graphics processing units, offer a compelling path to navigating the trade-offs between performance and power. H…

Ground calibration plan for the Athena/X-IFU microcalorimeter spectrometer
The X-ray Integral Field Unit is the X-ray imaging spectrometer on-board one of ESA's next large missions, Athena. Athena is set to investigate the theme of the Hot and Energetic Universe, with a launch planned in the late-2030s. Based on a high sensitivity Transition Edge Sensor (TES) detector array operated at very low temperature (50 mK), X-IFU will provide spatially resolved high resolution spectroscopy of the X-ray sky in the 0.2-12 keV energy band, with an energy resolution goal of 4 eV u…

#Bezos in #Venedig. Nichts dagegen zu sagen, wenn er sich dort wie ein normaler Tourist benimmt, also ohne dass die Stadt durch Sicherheitsvorkehrungen lahm gelegt wird. Wenn es ihm zu riskant ist, mit einige Freunden einfach so in der Stadt zu heiraten, dann soll er das wo anders machen.
Er ist, wie es sc…

Servus beieinand,
am 17.7.ist Firmenlauf in Ingolstadt. Meiner einer hat sich angemeldet 😄, weil Mann auch walken darf. Heute hab ich mal getestet, was die Beine und reparierten Kniee so hergeben.
Unter 50 Minuten bin ich geblieben, fürs erste Training nicht schlecht. Vielleicht kann ich unter 45 Minuten bleiben? Mal kukken 😁
Achja, frönt dem Feiertag schön!

Accelerating Matrix Multiplication: A Performance Comparison Between Multi-Core CPU and GPU
Matrix multiplication is a foundational operation in scientific computing and machine learning, yet its computational complexity makes it a significant bottleneck for large-scale applications. The shift to parallel architectures, primarily multi-core CPUs and many-core GPUs, is the established solution, and these systems are now ubiquitous from datacenters to consumer laptops. This paper presents a direct, empirical performance analysis of matrix multiplication on a modern, consumer-grade heter…
