INSUBCONTINENT EXCLUSIVE:
Nvidia is recommending a mitigation for customers of one of its GPU product lines that will degrade performance by up to 10 percent in a bid
to protect users from exploits that could let hackers sabotage work projects and possibly cause other compromises.The move comes in response
available from many cloud services
A vulnerability the researchers discovered opens the GPU to Rowhammer, a class of attack that exploits physical weakness in DRAM chip
By repeatedly hammering carefully chosen rows, the attack induces bit flips in nearby rows, meaning a digital zero is converted to a one or
Until now, Rowhammer attacks have been demonstrated only against memory chips for CPUs, used for general computing tasks.That changed last
week as researchers unveiled GPUhammer, the first known successful Rowhammer attack on a discrete GPU
Traditionally, GPUs were used for rendering graphics and cracking passwords
In recent years, GPUs have become the workhorses for tasks such as high-performance computing, machine learning, neural networking, and
No company has benefited more from the AI and HPC boom than Nvidia, which last week became the first company to reach a $4 trillion
While the researchers demonstrated their attack against only the A6000, it likely works against other GPUs from Nvidia, the researchers
autonomous driving, healthcare applications, and medical imaging for analyzing MRI scans
The single bit flip can increase the exponent value by 16
The result is an altering of the model weight by a whopping 216, degrading model accuracy from 80 percent to 0.1 percent, said Gururaj
Saileshwar, an assistant professor at the University of Toronto and co-author of an academic paper demonstrating the attack.
