Prototype performance of distributed DAQ using HORB based on Java

Java Performance for DAQ

J ava i s a key t ec hnology for t he next gene ra ti on of dat a ac qui s it i on s ys t em s (DAQ ). J ava has excellent features, but its performance is a weak point. We evaluated various Java benchmark progr am s wi t h a J ava i nt erpr et er , J ava J us t -I n-Ti m e com pi l er s (J I T), a J ava nat i ve code compiler (TowerJ) which generates native code, and a C compiler. The benchmar...

HORB: Distributed Execution of Java Programs

HORB is a Java ORB (Object Request Broker) that extends Java for distributed object oriented computing. Applications of HORB and HORB itself are network portable and transferable, since HORB provides both portability and interoperability among diierent kinds of OSs. This paper describes the organization and the main features of HORB. It provides remote object creation/connection, remote method ...

Evaluation of Gigabit Ethernet with Java / HORB

We h a ve e v aluated a high speed network, Gigabit Ethernet(GbE), with Java/HORB, which means Java and Java-based Distributed Object Technology(DOT). Next generation of data acquisition(DAQ) needs high speed network such a s A TM and GbE for data transfer in Level 3 and/or Level 2 trigger of the DAQ at large scale DAQ system like Large Hadron Collider(LHC). When evaluating the basic parameters...

HORB: Distributed Object Technology

A study of network - based data acquisition system

Network technologies such as Java and Microsoft ActiveX may become powerful tools to construct the distributed and scalable data acquisition system(DAQ). We have developed Java interface to CAMAC and investigated the application of HORB(distributed Java) to the DAQ. We have also evaluated Microsoft OLEautomation technique(OCX) with combining the objects to Excel as the analysis process over net...
