  1. #GPUHammer is the first attack to show #Rowhammer bit flips on #GPU memories, specifically on a GDDR6 memory in an #NVIDIA A6000 GPU. Our attacks induce bit flips across all tested DRAM banks, despite in-DRAM defenses like TRR, using user-level #CUDA #code. These bit flips allow a malicious GPU user to tamper with another user’s data on the GPU in shared, time-sliced environments. In a proof-of-concept, we use these bit flips to tamper with a victim’s DNN models and degrade model accuracy from 80% to 0.1%, using a single bit flip. Enabling Error Correction Codes (ECC) can mitigate this risk, but ECC can introduce up to a 10% slowdown for #ML #inference workloads on an #A6000 GPU.

  2. Widescreen Wonder: #LasVegasSphere
    54,000 m2 (~3.67 acre) interior LED display (16x16K) and an exterior LED display (‘Exosphere’) consisting out of 1.23 million LED ‘pucks’. Driving all these pixels are around 150 #NVidia RTX #A6000 #GPU, installed in computer systems which are networked using NVidia #BlueField data processing units (#DPU) and NVidia #ConnectX6 NICs (up to 400 Gb/s), with visual content transferred from Sphere Studios in Cali. All this hardware uses 45kW.

  3. Morning Walk, Grass Valley California

    I like to walk here in the morning whenever I visit my sister-in-law. It's peaceful and my dog loves the rural scents of wildlife and horses.
