We describe the development of an FX-style correlator for very long baseline interferometry (VLBI), implemented in software and intended to run in multiprocessor computing environments, such as large clusters of commodity machines (Beowulf clusters) or computers specifically designed for high-performance computing, such as multiprocessor shared-memory machines. We outline the scientific and practical benefits for VLBI correlation, these chiefly being due to the inherent flexibility of software… Expand
A real-time software backend for the GMRT
TLDR
This paper has built a correlator and a beamformer, using PCI-based ADC cards and a Linux cluster of 48 nodes with dual gigabit inter-node connectivity for real-time data transfer requirements, and believes this is the first instance of such a real- time observatory backend for an intermediate sized array like the GMRT.

DiFX-2: A More Flexible, Efficient, Robust, and Powerful Software Correlator
TLDR
The evolution in the capabilities of the DiFX correlator over the past three years is described, including a number of new capabilities, substantial performance improvements, and a large amount of supporting infrastructure to ease use of the code. Expand
The SFXC software correlator for very long baseline interferometry: algorithms and implementation
TLDR
The correlation algorithm is explained in detail, as are some of the novel modes that software correlation has enabled, such as wide-field VLBI imaging through the use of multiple phase centres and pulsar gating and binning. Expand
The LOFAR correlator: implementation and performance analysis
TLDR
To meet the real-time requirements, the application is highly optimized, and reaches exceptionally high computational and I/O efficiencies, and the scalability of the system is studied, and it is shown that it scales well beyond the requirements. Expand
An AIPS-based, distributed processing method for large radio interferometric datasets
TLDR
A lightweight infrastructure is reported on that enables the deployment of AIPS interferometric processing routines on distributed systems in an autonomous and fault tolerant manner and is used to search for sources of 6.7 GHz methanol maser emission in the Cep A region with the European VLBI Network.

Automatic Mapping of Real Time Radio Astronomy Signal Processing Pipelines onto Heterogeneous Clusters
TLDR
This work presents a tool called Optimal Rearrangement of Cluster-based Astronomy Signal Processing, or ORCAS, that automatically determines how to optimally partition an instrument across different types of hardware for radio astronomy based on a high level description of the instrument and a set of benchmarks. Expand
A parallel model for the heterogeneous computation of radio astronomy signal correlation
TLDR
This thesis first implemented a FX correlator on the GPU, with a performance increase of one to two orders of magnitude over a serial CPU approach, which combines pairs of telescope signals in the Fourier domain. Expand
Processing Real-Time LOFAR Telescope Data on a Blue Gene/P
LOFAR is the first of a new generation of radio telescopes. Rather than using expensive dishes, it forms a distributed sensor network that combines the signals from many thousands of simple antennas.Expand

TLDR
In this system, coherence at the two elements is maintained through the use of two highly stable, atomic oscillators, which makes operation possible at very long base lines because of the lack of communication link between the elements of the interferometer. Expand
