Argus-G: A Low-Cost Error Detection Scheme for GPGPUs
نویسندگان
چکیده
We have developed Argus-G, a low-cost error detection mechanism for the SIMT cores found in GPGPUs. As GPUs make the transition into general purpose computing, detecting errors and dealing with them will become a more pressing issue. General purpose graphics processing units are increasingly used for scientific computing, where errors, if not detected, can significantly distort the results of these scientific simulations. Argus-G is an adaptation of the Argus error detection scheme for general purpose cores that has been tailored for GPUs. Our experiments show that, on average, our implementation incurs a 4% overhead in runtime and a 10% increase in the number of instructions executed.

Proving the Completeness of the Composition of Two Dynamic Verification Techniques
There has been a significant amount of recent research in low-cost mechanisms for detecting errors in computer execution that are due to hardware faults. One exciting, low-cost approach to error detection is dynamic verification (sometimes also called online testing or runtime invariant checking). The idea is for the hardware to dynamically (i.e., at runtime) check whether certain necessary inv...

Reversible logic is one of the new paradigms for power optimization that can be used instead of the current circuits. Moreover, the fault-tolerance capability in the form of error detection or error correction is a vital aspect for current processing systems. In this paper, as the multiplication is an important operation in computing systems, some novel reversible multiplier designs are propose...
متن کاملIntegration Scheme for SINS/GPS System Based on Vertical Channel Decomposition and In-Motion Alignment
Accurate alignment and vertical channel instability play an important role in the strap-down inertial navigation system (SINS), especially in the case that precise navigation has to be achieved over long periods of time. Due to poor initialization as well as the cumulative errors of low-cost inertial measurement units (IMUs), initial alignment is not sufficient to achieve required navigation ac...

In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
متن کاملA New Formulation for Cost-Sensitive Two Group Support Vector Machine with Multiple Error Rate
Support vector machine (SVM) is a popular classification technique which classifies data using a max-margin separator hyperplane. The normal vector and bias of the mentioned hyperplane is determined by solving a quadratic model implies that SVM training confronts by an optimization problem. Among of the extensions of SVM, cost-sensitive scheme refers to a model with multiple costs which conside...
