In this podcast, Franck Cappello from Argonne describes EZ, an effort to effort to compress and reduce the enormous scientific data sets that some of the ECP applications are producing. The current ...

Today, we’re going to talk about lossless compression. So last episode we talked about some basic file formats, but what we didn’t talk about is compression. Often files are way too large to be easily ...

Fig 5. Lossy compression creates decompressed data that still provides sufficient detail for images and data processing. Multicore central processing unit (CPU) and graphics processing unit (GPU) ...

It used to be that memory and storage space were so precious and so limited of a resource that handling nontrivial amounts of text was a serious problem. Text compression was a highly practical ...

A team of researchers at ETH Zurich are working on a novel approach to solving increasingly large graph problems. Large graphs are a basis of many problems in social sciences (e.g., studying human ...

Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality.

There are two categories of data compression. The first reduces the size of a single file to save storage space and transmit faster. The second is for storage and transmission convenience. The JPEG ...
