Reverse engineering power management on NVIDIA GPUs - Anatomy of an autonomic-ready system Martin Peres Ph.D. student at LaBRI University of Bordeaux Hobbyist Linux/Nouveau Developer Email: [email protected] Abstract—Research in power management is currently limited supported nor documented by NVIDIA. As GPUs are leading by the fact that companies do not release enough documentation the market in terms of performance-per-Watt [3], they are or interfaces to fully exploit the potential found in modern a good candidate for a reverse engineering effort of their processors. This problem is even more present in GPUs despite power management features. The choice of reverse engineering having the highest performance-per-Watt ratio found in today’s NVIDIA’s power management features makes sense as they processors.

GMAI: a GPU Memory Allocation Inspection Tool for Understanding and Exploiting the Internals of GPU Resource Allocation in Critical Systems
The final publication is available at ACM via http://dx.doi.org/ 10.1145/3391896 GMAI: A GPU Memory Allocation Inspection Tool for Understanding and Exploiting the Internals of GPU Resource Allocation in Critical Systems ALEJANDRO J. CALDERÓN, Universitat Politècnica de Catalunya & Ikerlan Technology Research Centre LEONIDAS KOSMIDIS, Barcelona Supercomputing Center (BSC) CARLOS F. NICOLÁS, Ikerlan Technology Research Centre FRANCISCO J. CAZORLA, Barcelona Supercomputing Center (BSC) PEIO ONAINDIA, Ikerlan Technology Research Centre Critical real-time systems require strict resource provisioning in terms of memory and timing. The constant need for higher performance in these systems has led industry to recently include GPUs. However, GPU software ecosystems are by their nature closed source, forcing system engineers to consider them as black boxes, complicating resource provisioning. In this work we reverse engineer the internal operations of the GPU system software to increase the understanding of their observed behaviour and how resources are internally managed. We present our methodology which is incorporated in GMAI (GPU Memory Allocation Inspector), a tool which allows system engineers to accurately determine the exact amount of resources required by their critical systems, avoiding underprovisioning. We first apply our methodology on a wide range of GPU hardware from different vendors showing itsgeneralityin obtaining the properties of the GPU memory allocators. Next, we demonstrate the benefits of such knowledge in resource provisioning of two case studies from the automotive domain, where the actual memory consumption is up to 5.6× more than the memory requested by the application.

This work focuses on thermal compact system design and reduction in the distance between channels, and shows how the heat, or temperature, can modules. However, this can introduce security vulnerabilities. be measured without special measurement equipment or In particular, this work shows that due to the close physical physical access in commodity SoC devices. Especially, this proximity of a System-on-a-Chip (SoC) package and a PoP work focuses on an SoC DRAM Package-on-Package (PoP) DRAM that is on top of it, a thermal covert channel exists conﬁguration [6] where two chips (SoC and DRAM) are between the SoC and the PoP DRAM. The thermal covert stacked on top of each other. The heat transfers between the channel can allow multiple cores in the SoC to communicate two can be observed by measuring decay rate of DRAM by modulating the temperature of the PoP DRAM. Especially, cells, which is the basis for this work. it is possible for one core in the SoC to generate heat patterns, Previously, heat-based or thermal covert channels have which encode data that is to be transmitted, and another been demonstrated in data centers [7], or in multicore core to observe the transmitted pattern by measuring the processors [8], but these require dedicated thermal sensors decay rate of DRAM cells.
