    • n orca In mammalogy, a genus of marine delphinoid odontocete cetaceans, containing the numerous species known as killers, sword-fish, or grampuses. They are remarkable for their strength, ferocity, and predatory habits, and are the only cetaceans which habitually prey upon warm-blooded animals, such as those of their own order. The teeth are about 48 in number, implanted all along the jaws; the vertebræ are 50–52, of which the cervicals are mostly free; the flippers are very large, and oval; the dorsal fin is high, erect, pointed, and situated about the middle of the body; and the head is obtusely rounded.
    • n orca In ornithology, that part of the tracheal tympanum of a bird which is formed by the more or less coössified rings of the bronchi. See tympanum.

In science:

Almost 6 million events were simulated with the CMS GEANT3-based detector simulation program CMSIM and then digitised and reconstructed under a variety of conditions with the CMS Ob ject Oriented reconstruction and analysis program ORCA based on the COBRA framework.
CMS Data Analysis: Current Status and Future Strategy
The DAQ software system will be constructed using the Object-oriented Real-time Control and Acquisition (ORCA) application which provides a general purpose, highly modular, object-oriented, acquisition and control system that is easy to develop, use, and maintain.

In Orca the acquire/release happens transparently on shared objects that get replicated.
Extending and Implementing the Self-adaptive Virtual Processor for Distributed Memory Architectures
However, the detector dependent issues like the resolutions of the narrow mass states, missing transverse energy resolution, b - and τ -tagging and jet resolution are studied with full GEANT-based (CMSIM and ORCA) detector simulation.
Summary of the CMS Discovery Potential for the MSSM SUSY Higgses
Promising results are obtained from a study on the identification of the 3-prong τ vertex with full (ORCA) track reconstruction . A rejection factor of ∼ 5 is obtained against the 3-prong QCD jets with an efficiency o f ∼ 70% for the τ jets.
