Fault-tolerance is an essential requirement for real-time systems, due to potentially
catastrophic consequences of faults. In this paper, we investigate an efficient off-line …

In this paper, we investigate an efficient off-line scheduling algorithm in which real-time tasks
with precedence constraints are executed in a heterogeneous environment. It provides more …

Many time-critical applications require dynamic scheduling with predictable performance.
Tasks corresponding to these applications have deadlines to be met despite the presence of …

Nowadays, the performance of heterogeneous systems has been improved dramatically,
which also increases the complexity of heterogeneous systems, leading to the growing …

Real time systems are being increasingly used in several applications which are time critical
in nature. Fault tolerance is an important requirement of such systems, due to the …

In real-time systems, tasks have deadlines to be met despite the presence of faults. Primary-
Backup (PB) scheme is one of the most important schemes that has been employed for fault …

Fault-tolerant scheduling plays a significant role in improving system reliability of clusters.
Although extensive fault-tolerant scheduling algorithms have been proposed for real-time …

In this paper, a heuristic dynamic scheduling scheme for parallel real-time jobs executing on
a heterogeneous cluster is presented. In our system model, parallel real-time jobs, which are …

Heterogeneous distributed systems are widely deployed for executing computationally
intensive parallel applications with diverse computing needs. Such environments require …

Fault tolerance is an important aspect of real-time computer systems, since timing
constraints must not be violated. When dealing with multiprocessor systems, fault tolerance …
