High-resolution climate simulations require tremendous computing resources and can generate massive datasets. At present, preserving the data from these simulations consumes vast storage resources at institutions such as the National Center for Atmos

This paper examines whether lossy compression can be used effectively in physics simulations as a possible strategy to combat the expected data-movement bottleneck in future high performance computing architectures. We show that, for the codes and si

While the amount of data used by today’s high-performance computing (HPC) codes is huge, HPC users have not broadly adopted data compression techniques, apparently because of a fear that compression will either unacceptably degrade data quality or

Compression of computed tomography (CT) projection data reduces CT scanner bandwidth and storage costs. Since fixed-rate compression guarantees predictable bandwidth, fixed-rate compression is preferable to lossless compression, but fixed-rate compre

Compression of computed tomography (CT) projection samples reduces slip ring and disk drive costs. A lowcomplexity, CT-optimized compression algorithm called Prism CTTM achieves at least 1.59:1 and up to 2.75:1 lossless compression on twenty-six CT p

This paper describes the Samplify family of lossless and lossy real-time compression algorithms for FPGAs and ASICs, operating at rates up to 40 Gsamp/sec, which achieve efficient, cost-effective compression of between 2:1 and 8:1. Compression for me

Highly linear wideband power amplifiers (PAs) are needed for code division multiple access (CDMA) and orthogonal frequency division multiplex (OFDM) modulations. Such PAs normally have low operating efficiency because of the high peak-to-average rati

The automatic estimation of baud rate is an important capability of automatic signal identification and classification systems. Several practical techniques are used for this purpose. The chosen technique is usually optimal in some sense, minimizing
