Hierarchical Storage from NVMe to Tapes
EMOSS '22: Proceedings of the 2022 Workshop on Emerging Open Storage Systems and Solutions for Data Intensive ComputingPages 3–4https://doi.org/10.1145/3526061.3532096Hierarchical storage allows to build both high-performance and high-capacity storage systems by combining various technologies like NVMe, SSDs, HDDs, or tapes.
While most existing systems only manage a limited number of levels and technologies, the IO-...

Cost of Tape versus Disk for Archival Storage
CLOUD '14: Proceedings of the 2014 IEEE International Conference on Cloud ComputingPages 208–215https://doi.org/10.1109/CLOUD.2014.37For archiving large datasets in high-performance computing facilities, tape technology has a long history of providing inexpensive capacity. However, as the memory-size of supercomputers continues to grow geometrically, the cost of tape bandwidth is ...

From Machine and Tape to Structure and Function: Formulation of a Reflexively Computing System
The relationship between structure and function is explored via a system of labeled directed graph structures upon which a single elementary read/write rule is applied locally. Boundaries between static (information-carrying) and active (information-...

Collapsing Oracle-Tape Hierarchies
Other authors have shown that equipping a logspace oracle Turing machine with more than one oracle tape may result in an increased computational power. We are interested in the inverse problem: For which oracle classes C does the oracle-tape hierarchy ...

Organization and Access of Image Data by Areas
IEEE Transactions on Pattern Analysis and Machine Intelligence (ITPM), Volume 1, Issue 1Pages 50–60https://doi.org/10.1109/TPAMI.1979.4766875This paper concerns methods for indexing areas in twodimensional array data. A method for naming subpictures from rasterscan image data is presented with notation that eases their subsequent storage access. Equations are given for converting each ...

Subroutinized tape sorting
AbstractThe drawbacks of large, general tape sorting programs are pointed out, and a sorting subroutine is suggested as a remedy. The fundamental idea is the separation of the logic in tape sorting from the actual manipulation of external tape units by ...
