Soft error rates in processors have been increasing with decreasing feature size and larger chips. Software-only solutions have been proposed to deal with ...

Nov 17, 2015 · Soft errors are infrequent enough to allow correction to be rel- atively slow. Detection, on the other hand, has to be continuous and thus fast.

The results show that, if error check- ers were inserted at synchronization points only, the SIMD based soft error detection leads to only 1.32x performance.

This paper proposes a novel approach to instruction duplication, which exploits the redundancy within SIMD instructions, and is implemented in the LLVM ...

SIMD-Based Soft Error Detection. Zhi Chen, Alex Nicolau, Alexander V. Veidenbaum, “SIMD-Based Soft Error Detection,” CECS TR 15-04, posted on November 23, 2015.

The goal of this dissertation is to automatically generate and optimize SIMD-based instruc- tion duplication in a compiler. It focuses on soft error detection.

We find that it is possible to leverage under-utilized resources such as. SIMD capability of modern processors to optimally en- gineer EDDI at assembly level in ...

error detection by duplicating instruction (EDDI) has been proposed as a prominent software-based technique for detecting soft errors. ... SIMD and other compiler ...

Evaluation on a host of benchmarks reveal that proposed SIMD-based error detection technique causes much less performance, code size, and energy overheads.
