Lower back pain (LBP) is the second most common neurological ailment in the United States after the headache according to the National Institute of Neurological Disorders and Stroke. Over 11 million Americans have some sort of Intervertebral Disc Disease (IDD) costing over $50 billion annually for related diagnosis and rehabilitation of the patients. In this book, we propose a computer-aided diagnosis system for lumbar spine. our CAD system utilizes a set of machine learning-based solutions for diagnosis of lumbar inter-vertebral disc degenerative diseases (IDD). We study clinical MRI from our collaborating radiologists group and use their clinical diagnosis reports as our gold standard for diagnosis of each disc level in the lumbar area.

Computational clusters have long provided a mechanism for the acceleration of high performance computing (HPC) applications. With today's supercomputers now exceeding the petaflop scale, however, they are also exhibiting an increase in heterogeneity. Thisheterogeneity spans a range of technologies, from multiple operating systems to hardware accelerators and novel architectures. Because of the exceptional acceleration some of these heterogeneous architectures provide, they are being embraced as viable tools for HPC applications. Given the scale of today's supercomputers, it is clear that scientists must consider the use of fault-tolerance in their applications. This is particularly true as computational clusters with hundreds and thousands of processors become ubiquitous in large-scale scientific computing, leading to lower mean-times-to-failure. This forces the systems to effectively deal with the possibility of arbitrary and unexpected node failure. In this book the address the issue of fault-tolerance via checkpointing. They discuss the existing strategies to provide rollback recovery to applications -- both via MPI at the user level and through application-level techniques. Checkpointing itself has been studied extensively in the literature, including the authors' own works. Here they give a general overview of checkpointing and how it's implemented. More importantly, they describe strategies to improve the performance of checkpointing, particularly in the case of distributed systems.
