The need for fault tolerance and availability generally implies some form of redundancy of the same (key, value) pair over multiple machines.
Besides fault tolerance and availability, distribution can enhance parallel processing of the given data, in particular when computing tasks can be executed independently on distinct subsets of the data.
In our efforts to provide a high degree of fault tolerance and availability for the Pipeline service, we developed a restartable JGDI plugin that runs in a separate process.
In fact, enterprise-class virtualization platforms include features such as fault tolerance and high availability that are designed to provide a high level of business continuity even for applications that were not originally designed to be highly available.
Fault tolerance and high availability at shop-floor level are provided due to the multiple physical communication capabilities of the robot controllers, to their multiple-axis multitasking operating capability, and to hardware redundancy of single points of failure (SPOF).
This way, its increased usage in many scientific areas reveals new scenarios where fault-tolerance and high availability should be considered.
Previously, this field of knowledge suffered some setbacks as technology was still at its developing stage, but with better tolerances and the availability of better materials, this technology is now a reality.
The reason is twofold: (i) The time for collecting information from all the candidate relays may exceed the PU's end-to-end delay tolerance, and (ii) the availability of candidate relays may change during the collecting time as CR links are generally not stable.
Availability of high quality reference genome sequence of rice, knowledge of exact position of genes/QTLs governing tolerance to abiotic stresses and availability of DNA markers linked to these traits has opened up opportunities for breeders to transfer the favorable alleles into widely grown rice varieties through marker-assisted backcross breeding (MABB).
With the rising prevalence of marijuana use, potency, social tolerance, early age of onset and availability, drug testing in drivers should be strengthened and expanded and effective intervention programs to reduce DUID and its adverse consequences should be implemented.
With the rising prevalence of marijuana use, potency, social tolerance, early age of onset and availability (Brady & Li 2014; Cerda et al. 2012; Lynne-Landsman et al. 2013; O'Malley & Johnston 2007), public health efforts should focus on strengthening and expanding drug testing as well as intervention programs for drivers.
