DeLag: Detecting Latency Degradation Patterns in Service-based Systems [article]

Luca Traini, Vittorio Cortellessa
2021 arXiv   pre-print
In this paper we present DeLag, a novel automated search-based approach for diagnosing performance issues in service-based systems.  ...  We call such symptoms Latency Degradation Patterns. DeLag simultaneously search for multiple latency degradation patterns while optimizing precision, recall and latency dissimilarity.  ...  ACKNOWLEDGMENTS Luca Traini's work was supported by the project "Software Performance in Agile/DevOps context" funded within Programma Operativo Nazionale Ricerca e Innovazione 2014-2020.  ...

Problem Solving Environment Infrastructure for High Performance Computer Systems [chapter]

Daniel C. Stanzione, Walter B. Ligon
2000 Lecture Notes in Computer Science  
Unfortunately, construction of PSEs is difficult, usually proceeding in an ad hoc fashion. In this work, a methodology for constructing PSEs is proposed.  ...  Many fields in science and engineering need to make use of this computing power.  ...  Services provided at level 3 via agents might include an equation-based interface to the user, or an agent which presents a choice of linear system solvers to apply to the problem.  ...

We also expressed GFP-tagged MARCO in CHO-K1 cells. MWCNT adhered to MARCO first and were phagocytosed by the cells.  ...  Electron microscopic studies suggested that plasma membranes of the cells were directly injured by MWCNT resulting in necrotic cell death rather than apoptosis.  ...  Impact of rapid screening tests to prevent postoperative MRSA infections: PCR based systems are now available that detect MRSA within 1 day.  ...
