    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.

My name is Shayne Hodge. This is July 29, 2013 at the afternoon in the Computer History Museum. We have with us today the founders of 3dfx, a graphics company from the 1990s of considerable influence. From left to right on the camera-- I'll let you guys introduce yourselves. Gary Tarolli: I'm Gary Tarolli. Scott Sellers: I'm Scott Sellers. Ross Smith: Ross Smith. Gordon Campbell: And Gordon Campbell. Hodge: And so why don't each of you take about a minute or two and describe your lives roughly up to the point where you need to say 3dfx to continue describing them. Tarolli: All right. Where do you want us to start? Hodge: Birth. Tarolli: Birth. Oh, born in New York, grew up in rural New York. Had a pretty uneventful childhood, but excelled at math and science. So I went to school for math at RPI [Rensselaer Polytechnic Institute] in Troy, New York. And there is where I met my first computer, a good old IBM mainframe that we were just talking about before [this taping], with punch cards. So I wrote my first computer program there and sort of fell in love with computer. So I became a computer scientist really. So I took all their computer science courses, went on to Caltech for VLSI engineering, which is where I met some people that influenced my career life afterwards.

    The Bifrost GPU architecture and the ARM Mali-G71 GPU Jem Davies ARM Fellow and VP of Technology Hot Chips 28 Aug 2016 Introduction to ARM Soft IP . ARM licenses Soft IP cores (amongst other things) to our Silicon Partners . They then make chips and sell to OEMs, who sell consumer devices . “ARM doesn’t make chips”… . We provide all the RTL, integration testbenches, memories lists, reference floorplans, example synthesis scripts, sometimes models, sometimes FPGA images, sometimes with implementation advice, always with memory system requirements/recommendations . Consequently silicon area, power, frequencies, performance, benchmark scores can therefore vary quite a bit in real silicon… 2 © ARM2016 ARM Mali: The world’s #1 shipping GPU 750M 65 27 Mali-based new Mali GPUs shipped 140 Total licenses in in 2015 Total licenses licensees FY15 Mali is in: Mali graphics based IC shipments (units) 750m ~75% ~50% ~40% 550m of of of 400m DTVs… tablets… smartphones 150m <50m 2011 2012 2013 2014 2015 3 © ARM2016 ARM Mali graphics processor generations Mali-G71 BIFROST … GPU Unified shader cores, scalar ISA, clause execution, full coherency, Vulkan, OpenCL MIDGARD Mali-T600 GPU series Mali-T700 GPU series Mali-T800 GPU series Unified shader cores, SIMD ISA, OpenGL ES 3.x, OpenCL, Vulkan Presented at HotChips 2015 Mali-200 Mali-300 Mali-400 Mali-450 Mali-470 UTGARD GPU GPU GPU GPU GPU Separate shader cores, SIMD ISA, OpenGL ES 2.x 4 © ARM2016 Bifrost features .
