network performance of the Jboss application server
Local Computer Networks, 2013Co-Authors: Nabil Benothman, Jean-frederic Clere, Eryk Schiller, Peter Kropf, Remy MaucheratAbstract:Jboss Application Server (AS) uses java.io and the Apache Portable Runtime (APR) project to provide its HTTP connectors. Due to new features of upcoming specifications of the Java Enterprise Edition (Java EE), the existing connectors shall be replaced by modern non blocking Input/Outputs (I/Os). In this study, we review some modern I/O frameworks such as NIO.2 introduced by Java SE 7 and XNIO3 developed by Jboss. We compare their network performance by running a series of stress tests on client-server applications of limited functionality. As a result, we select NIO.2 as the most appropriate framework to specify and implement a new Jboss connector. Finally, we compare our newly implemented Java connector against the existing APR-based one by means of network performance measures.

COMPSAC - On the Performance of Transactional Remote Invocations over Commonly Used Transports
2008 32nd Annual IEEE International Computer Software and Applications Conference, 2008Co-Authors: I.s. Neto, Francisco ReverbelAbstract:We have measured the performance of transactional remote invocations over three commonly used transports: IIOP, SOAP/HTTP, and Jboss Remoting. In the IIOP case, our transactional invocations followed the CORBA OTS standard. In the SOAP/HTTP case, they followed the WS-Coordination and WS-AtomicTransaction standards. In the (non-standard) Jboss Remoting transport, they employed a transactional layer modeled after CORBA OTS. For each of those three transports, we evaluate the overhead of propagating the transactional context, the cost of creating and committing empty transactions, and the total overhead incurred when the two-phase commit protocol actually runs. We also evaluate the impact of the transaction log on the total overhead.

dynamic deployment of iiop enabled components in the Jboss server
Lecture Notes in Computer Science, 2004Co-Authors: Francisco Reverbel, Bill Burke, Marc J. FleuryAbstract:Jboss is an extensible Java application server that affords remote access to EJB components via multiple protocols. Its IIOP module supports IIOP-enabled EJBs, which are accessible both to RMI/IIOP clients written in Java and to CORBA clients written in various languages. While other systems use compilation-based approaches to generate IIOP stubs and skeletons, Jboss employs reflective techniques to avoid extra compilation steps and support on-the-fly deployment.

Middleware - The Jboss extensible server
Lecture Notes in Computer Science, 2003Co-Authors: Marc J. Fleury, Francisco ReverbelAbstract:Jboss is an extensible, reflective, and dynamically reconfigurable Java application server. It includes a set of components that implement the J2EE specification, but its scope goes well beyond J2EE. Jboss is open-ended middleware, in the sense that users can extend middleware services by dynamically deploying new components into a running server. We believe that no other application server currently offers such a degree of extensibility. This paper focuses on two major architectural parts of Jboss: its middleware component model, based on the JMX model, and its meta-level architecture for generalized EJBs. The former requires a novel class loading model, which Jboss implements. The latter includes a powerful and flexible remote method invocation model, based on dynamic proxies, and relies on systematic usage of interceptors as aspect-oriented programming artifacts.

the clustering of the sdss iv extended baryon oscillation spectroscopic survey dr14 quasar sample a tomographic measurement of cosmic structure growth and expansion rate based on optimal redshift weights
Monthly Notices of the Royal Astronomical Society, 2019Co-Authors: Hector Gilmarin, Will J Percival, Gongbo Zhao, Yuting Wang, Shun Saito, Dandan Wang, Chiahsun Chuang, Rossana RuggeriAbstract:We develop a new method, which is based on the optimal redshift weighting scheme, to extract the maximal tomographic information of baryonic acoustic oscillations (BAO) and redshift space distortions (RSD) from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 14 quasar (DR14Q) survey. We validate our method using the Extended Zel’dovich mocks, and apply our pipeline to the eBOSS DR14Q sample in the redshift range of 0.8 < |$z$| < 2.2. We report a joint measurement of fσ_8 and two-dimensional BAO parameters D_A and H at four effective redshifts of |$z$|_eff = 0.98, 1.23, 1.52, and 1.94, and provide the full data covariance matrix. Using our measurement combined with BOSS DR12, Main Galaxy Sample (MGS), and 6 degree Field Galaxy Survey (6dFGS) BAO measurements, we find that the existence of dark energy is supported by observations at a 7.4σ significance level. Combining our measurement with BOSS DR12 and Planck observations, we constrain the gravitational growth index to be γ = 0.580 ± 0.082, which is fully consistent with the prediction of general relativity. This paper is part of a set that analyses the eBOSS DR14 quasar sample.

the sdss iv extended baryon oscillation spectroscopic survey baryon acoustic oscillations at redshift of 0 72 with the dr14 luminous red galaxy sample
The Astrophysical Journal, 2018Co-Authors: Mariana Vargasmagana, B Camacho, Kyle S Dawson, Will J Percival, Julian E Bautista, J Brinkmann, Joel R Brownstein, Johan Comparat, Hector GilmarinAbstract:The extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 14 sample includes 80,118 luminous red galaxies (LRGs). By combining these galaxies with the high-redshift tail of the BOSS galaxy sample, we form a sample of LRGs at an effective redshift z = 0.72, covering an effective volume of 0.9 Gpc^3. We account for spurious fluctuations caused by targeting and by redshift failures, which were validated on a set of mock catalogs. This analysis is sufficient to provide a 2.5% measurement of spherically averaged baryon acoustic oscillations (BAO), D_v(z = 0.72) = 2377^(+61)_(-59)(r_d/r_(d,fid)) Mpc, at 2.8σ of significance. Together with the recent quasar-based BAO measurement at z = 1.5 and forthcoming emission line galaxy–based measurements, this measurement demonstrates that eBOSS is fulfilling its remit of extending the range of redshifts covered by such measurements, laying the groundwork for forthcoming surveys such as the Dark Energy Spectroscopic Survey and Euclid.

the sdss iv extended baryon oscillation spectroscopic survey baryon acoustic oscillations at redshift of 0 72 with the dr14 luminous red galaxy sample
arXiv: Cosmology and Nongalactic Astrophysics, 2017Co-Authors: Mariana Vargasmagana, B Camacho, Kyle S Dawson, Will J Percival, Julian E Bautista, J Brinkmann, Joel R Brownstein, Johan Comparat, Hector GilmarinAbstract:The extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 14 sample includes 80,118 Luminous Red Galaxies. By combining these galaxies with the high-redshift tail of the BOSS galaxy sample, we form a sample of LRGs at an effective redshift $z=0.72$, covering an effective volume of 0.9~Gpc$^3$. We introduce new techniques to account for spurious fluctuations caused by targeting and by redshift failures which were validated on a set of mock catalogs. This analysis is sufficient to provide a $2.6$\% measurement of spherically averaged BAO, $D_V(z=0.72) = 2353^{+63}_{-61} (r_d/r_{d,\rm{fid}}) h^{-1}$Mpc, at 2.8$\sigma$ of significance. Together with the recent quasar-based BAO measurement at $z=1.5$, and forthcoming Emission Line Galaxy-based measurements, this measurement demonstrates that eBOSS is fulfilling its remit of extending the range of redshifts covered by such measurements, laying the ground work for forthcoming surveys such as the Dark Energy Spectroscopic Survey and Euclid.
