The performance monitoring of computer systems is a complex affair, made even more challenging by the increasing gap between hardware and software. Methods that collect and feed data to performance analysis can usually be classified into one of two groups. ...
Real-time control systems (RTCSs) tolerate delay and crash faults by replicating the controller. Each replica computes and issues setpoints to actuators over a network that might drop or delay messages. Hence, the actuators might receive an inconsistent se ...
This paper investigates the problem of deriving a white box performance model of Hardware Transactional Memory (HTM) systems. The proposed model targets TSX, a popular implementation of HTM integrated in Intel processors starting with the Haswell family in ...
We are currently witnessing a shift towards the use of high-level programming languages for systems development. These approaches collide with the traditional wisdom which calls for using low-level languages for building efficient software systems. This sh ...
Performance critical software is almost always developed in C, as programmers do not trust high-level languages to deliver the same reliable performance. This is bad because low-level code in unsafe languages attracts security vulnerabilities and because d ...
The paper presents the results of design explorations for the implementation of the Smith-Waterman (S-W) algorithm executing DNA and protein sequences alignment. Both design explorations studies and the corresponding FPGA implementations are obtained by wr ...
Nowadays, massive amounts of point cloud data can be collected thanks to advances in data acquisition and processing technologies like dense image matching and airborne LiDAR (Light Detection and Ranging) scanning. With the increase in volume and precision ...
Real-time control systems (RTCSs) tolerate delay and crash faults by replicating the controller. Each replica computes and issues setpoints to actuators over a network that might drop or delay messages. Hence, the actuators might receive an inconsistent se ...
Digital PLLs are popular for on-chip clock generation due to their small size and technology portability. Variability tolerance is a key design challenge when designing such PLLs in an advanced CMOS technology. Environmental variations, such as mismatch, p ...
Blockchain systems have the potential to decentralise many traditionally centralised systems. However, scalability remains a key challenge. Without a horizontally scalable solution, where performance increases by adding more nodes to the system, blockchain ...
