Abstract

Embodiments of the present invention relate to collaging image data to form a large image using high-performance computing in a parallel computing environment. The collaging of the image data includes performing an intra-node merge operation on image data such that the merged intra-node data is not written to the file system, but instead maintained in volatile processor memory. The intra-node merged data is may then be communicated in a memory-to-memory manner over a high-speed network to another node in the system for an inter-node merge operation, which limits the number of intermediate system I/O operations to perform the collaging process. Following the intra-node and inter-node merge operations, tiles representing the collaged image may be written to a file system memory for persistent storage.

First claim

The invention claimed is:

1. A computer-implemented method in a computing environment utilizing a processor and memory for collaging image data, the method comprising:
receiving, through a computing network, a first plurality of image data inputs at a first node;
intra-node merging portions of the first plurality of image data inputs at the first node forming a first merged image data set;
receiving, at the first node, data from a second node about a second merged image data s…
