Fault Tolerance in Tandem Computer Systems [chapter]

Joel Bartlett, Jim Gray, Bob Horst
1987 The Evolution of Fault-Tolerant Computing  
A range of CPUs may be inter-connected via a hierarchical fault-tolerant local network. A variety of peripherals needed for online transaction processing are attached via dual ported controllers.  ...  A novel disc subsystem allows a choice between low cost-per-megabyte and low cost-per-access. System software provides processes and messages as the basic structuring mechanism.  ...  The kernel sends messages among processes in a processor and also to kernels of other processors which in turn send the message to the destination process.  ...

Commercial fault tolerance: a tale of two systems

W. Bartlett, L. Spainhower
2004 IEEE Transactions on Dependable and Secure Computing  
Both systems have a long history; the initial IBM S/360 machines were shipped in 1964, and the Tandem NonStop System was first shipped in 1976.  ...  The primary difference is that the S/360-zSeries focus has been on localized retry and restore to keep processors functioning as long as possible, while the NonStop developers have based systems on a loosely  ...  NonStop Server Percentages of recovery code are not available for the NonStop server kernel, but the intent is similar to that of z/OS: to identify and contain the scope of faults in order to minimize  ...

Training Recurrent Neural Network through Moment Matching for NLP Applications

Yue Deng, Yilin Shen, KaWai Chen, Hongxia Jin
2018 Interspeech 2018  
We propose a moment matching (MM) training strategy to alleviate such inconsistency by simultaneously taking these two distinct modes and their corresponding dynamics into consideration.  ...  We replace all inner product terms in Eq.2 with a kernel function k(·, ·), i.e. ψ(yi) T ψ(yj) = k(yi, yj). The kernel trick exhibits two indispensable properties for distribution matching.  ...  In this paper, we choose the Gaussian kernel as the default kernel function in the LMMD computation.  ...
