Ubuntu disables Intel GPU security mitigations, promises 20% performance boost
- Ubuntu is disabling Intel GPU security mitigations to provide a potential 20% boost in graphics performance on Intel-based systems.
- Spectre attacks leverage CPU performance enhancements to leak secrets, leading to the implementation of mitigations that usually degrade CPU performance over time.
- The decision by Ubuntu to disable these mitigations in the device driver for the Intel Graphics Compute Runtime follows consultations with Intel and aims to enhance performance.
- The change is expected to improve GPU performance in handling OpenCL framework or OneAPI Level Zero interface workloads, but users employing custom Linux kernels should ensure they keep compute runtime mitigations on.

Removing Azure Resource Manager reliance on Azure DevOps sign-ins
- Azure DevOps will no longer depend on Azure Resource Manager (ARM) resource during sign-ins or token refreshes, starting July 28, 2025.
- This change allows for more effective management of Azure DevOps access by implementing Azure DevOps-specific Conditional Access Policies (CAPs) instead of relying on ARM-based CAPs.
- Users who set up Conditional Access Policies for Azure resources like ARM, Azure portal, Azure Data Lake, etc., need to create new Azure DevOps-specific CAPs for continued coverage.
- Notable exceptions include billing administrators and service connection creators who still require ARM access for specific tasks within Azure DevOps.

Towards the Giga IOPS pipedream: How Nvidia wants to reach 100 million IOPS - even if it means inventing totally new types of memory
- Nvidia aims to push storage to match AI demands by targeting 100 million IOPS for small-block random reads, a huge goal according to Silicon Motion CEO.
- AI inference often involves small, scattered data bits, making 512B random reads crucial but challenging to accelerate.
- Current PCIe 5.0 SSDs reach around 14.5GB/s and 2-3 million IOPS, but Nvidia seeks faster storage solutions to keep up with AI advancements.
- Industry players like Kioxia are developing new memory technologies, such as XL-Flash, to meet ultra-fast storage demands, but further innovation is needed to achieve 100 million IOPS cost-effectively.
