Persistent memory is a new tier of memory that functions as a hybrid of traditional storage systems and main memory. It combines the benefits of both: the data persistence property of storage with the fast load/store interface of memory. Yet, efficiently supporting data persistence in memory requires non-trivial effort. In particular, logging is a widely used data persistence scheme due to its ...

porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. it is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. there are three main petrophysical...

Logging has been a common practice for monitoring and diagnosing performance issues. However, logging comes at a cost, especially for large-scale online service systems. First, the overhead incurred by intensive logging is non-negligible. Second, it is costly to diagnose a performance issue if there are a tremendous amount of redundant logs. Therefore, we believe that it is important to limit t...

The need for secure logging is well-understood by the security professionals, together with each researchers and practitioners. The flexibility to the accuracy verifies all (or some) log entries is very important to any application using secure logging techniques. During this paper, we start by examining progressive in secure logging and determine some issues inherent to systems supported trust...

This paper presents a new algorithm for supporting fault tolerant objects in distributed object oriented systems. The fault tolerance provided by the algorithm is fully user transparent. The algorithm uses checkpointing and message logging scheme. However the novelty of this scheme is in identifying the checkpointing instances such that the checkpointing time will not aaect the regular response...
