  • Middleware Mobility Paper SSRN
    STANDARDIZED TOOLS AND THE GENERALIZABILITY OF HUMAN CAPITAL: THE IMPACT OF STANDARDIZED TECHNOLOGIES ON EMPLOYEE MOBILITY Milan Miric University of Southern California ([email protected]) Hakan Ozalp KIN Center for Digital Innovation, VU Amsterdam ([email protected]) Abstract The mobility of highly skilled knowledge and creative workers is an important determinant of innovation. Existing studies have not considered how the use and diffusion of standardized technologies and tools influence the mobility of individual knowledge workers. We theorize that the diffusion of standardized tools increases the generalizability of human capital and, in turn, increases the ability of individuals to move between companies. Using data on the use of middleware in the console games industry, we find that this diffusion of standardized middleware tools lead to an increase in labor mobility on average, but was associated with higher mobility for individuals with skills that complemented those tools, in comparison to those that were substituted by these tools. Worker experience with standardized tools amplified these effects, as individuals who were experienced in using these tools saw the largest shift in the likelihood of mobility. We do not find that this diffusion led to individuals leaving the industry, but we do find evidence that the diffusion of a common set of tools within an industry was associated with workers being less likely to leave that industry. These results highlight the potential unintended effects of technological standardization and the broad diffusion of standardized tools, which may enable workers to more easily shift between competitors. 1. INTRODUCTION Human capital is a key resource for organizations and can be a key determinant of firm innovativeness, competitiveness, and survival.

  • Intel® Openvino™ with FPGA Support Through the Intel FPGA Deep Learning Acceleration Suite
    SOLUTION BRIEF Intel® OpenVINO™ with FPGA Support Through the Intel FPGA Deep Learning Acceleration Suite Intel® FPGA Deep Learning Acceleration Suite enables Intel FPGAs for accelerated AI optimized for performance, power, and cost. Introduction Artificial intelligence (AI) is driving the next big wave of computing, transforming both the way businesses operate and how people engage in every aspect of their lives. Intel® FPGAs offer a hardware solution that is capable of handling extremely challenging deep learning models at unprecedented levels of performance and flexibility. The Intel OpenVINO™ toolkit is created for the development of applications and solutions that emulate human vision, and it provides support for FPGAs through the Intel FPGA Deep Learning Acceleration Suite. The Intel FPGA Deep Learning Acceleration Suite is designed to simplify the adoption of Intel FPGAs for inference workloads by optimizing the widely used Caffe* and TensorFlow* frameworks to be applied for various applications, including image classification, computer vision, autonomous vehicles, military, and medical diagnostics. Intel FPGAs offer customizable performance, customizable power, deterministic low latency, and flexibility for today’s most widely adopted topologies as well as programmability to handle emerging topologies. Unique flexibility, for today and the future, stems the ability of Intel FPGAs to support emerging algorithms by enabling new numeric formats quickly. What makes FPGAs unique is its ability to achieve high performance through parallelism coupled with the flexibility of hardware customization – which is not available on CPU, GPU, or ASIC architectures. Turnkey Solution Offers Faster Time to Market The Intel Programmable Acceleration Card with Intel Arria® 10 GX FPGA (Intel PAC with Intel Arria 10 GX FPGA) combined with the Intel FPGA Deep Learning Acceleration Suite offer an acceleration solution for real-time AI inference with low latency as a key performance indicator.
