Architectural support for shadow memory in multiprocessors
- In VEE
, 2009
"... Runtime monitoring support serves as a foundation for the important tasks of providing security, performing debugging, and improving performance of applications. Often runtime monitoring requires the maintenance of information associated with each of the application’s original memory location, which ..."

FT-MPI: Fault Tolerant MPI, supporting dynamic applications in a dynamic world
, 2000
"... . Initial versions of MPI were designed to work efficiently on multiprocessors which had very little job control and thus static process models, subsequently forcing them to support dynamic process operations would have effected their performance. As current HPC systems increase in size with hig ..."

Supporting task migration in multi-processor systems-on-chip: a feasibility study
- Proc
, 2006
"... With the advent of multi-processor systems-on-chip, the interest in process migration is again on the rise both in research and in product development. New challenges associated with the new scenario include increased sensitivity to implementation complexity, tight power budgets, requirements on exe ..."

for the constraints of single chip multiprocessors with distributed operating systems. Load balancing in the system is maintained by means of intelligent initial placement and task migration. We propose a user-managed migration scheme based on code checkpointing and user-level middleware support as an effective
ATLAS: A Chip-Multiprocessor with Transactional Memory Support
"... Chip-multiprocessors are quickly becoming popular in embedded systems. However, the practical success of CMPs strongly depends on addressing the difficulty of multithreaded application development for such systems. Transactional Memory (T M) promises to simplify concurrency management in multithread ..."

PC cores that access coherent shared memory in a transactional manner. The data cache for each core is modified to support the speculative buffering and conflict detection necessary for transactional execution. We have mapped ATLAS to the BEE2 multi-FPGA board to create a full-system prototype
File System Support for Delta Compression
, 2000
"... Delta compression, which consists of compactly encoding one le version as the result of changes to another, can improve eciency in the use of network and disk resources. Delta compression techniques are readily available and can result in compression factors of ve to ten on typical data. Managing de ..."

-compressed storage. Existing tools for managing delta-compressed storage suer from weak le system support. Lack of transaction support is responsible for inecient application behavior. The only atomic operation in the traditional le system forces unnecessary disk activity due to copying costs. I will demonstrate
A Flexible Scheme for Scheduling Fault-Tolerant Real-Time Tasks on Multiprocessors
"... The recent introduction of multicore system-on-a-chip architectures for embedded systems opens a new range of possibilities for both increasing the processing power and improving the fault-robustness of real-time embedded applications. Fault-tolerance and performance are often contrasting requiremen ..."

In particular, we apply hierarchical scheduling techniques to efficiently support fault-tolerant, fault-silent and non
CoMOS: An Operating System for Heterogeneous Multi-Processor Sensor Devices
