In this paper we discuss the design and use of a fault-tolerant MPI (FT-MPI) that handles process failures in a way beyond that of the original MPI static process model. FTMPI allows the semantics and associated modes of failures to be explicitly controlled by an application via a modified functionality within the standard MPI 1.2 API. Given is an overview of the FT-MPI semantics, architecture ...

The IBM RS/6000 SP system is one of the most costeffective commercially available high performance machines. IBM RS/6000 SP systems support the Message Passing Interface standard (MPI) and LAPI. LAPI is a low level, reliable and efficient one sided communication API library, implemented on IBM RS/6000 SP systems. This paper explains how the high performance of the LAPI library has been exploite...

AIMS To evaluate the diagnostic accuracy of a combined non-invasive assessment of coronary artery disease with coronary CT angiography (CTA) and myocardial perfusion imaging (MPI) for the detection of flow-limiting coronary stenoses and its potential as a gatekeeper for invasive examination and treatment. METHODS AND RESULTS In 78 patients (mean age 65 +/- 9 years) referred for coronary angio...

Background—ACC/AHA Appropriate Use Criteria recommend performing stress MPI for intermediate to high-risk patients presenting with syncope, but not for low-risk patients. However, there are limited data to support these recommendations. We investigated the yield of stress MPI for the evaluation of syncope in patients at risk but without known CAD Methods and Results—From the Cleveland Clinic IR...

Communication library is a substantially important part for the development of the parallel applications on PC clusters. MPI is currently the most important messaging passing standard being used worldwide. Although powerful, MPI is very complex and require a certain amount of effort to learn. In fact, only a basic set of MPI functions is enough to develop a large class of parallel applications....

BACKGROUND The Multidimensional Pain Inventory (MPI) is a reliable and valid self-report instrument that measures the impact of pain on an individual's life, quality of social support and general activity. Criticism of the MPI has focused on this instrument's internal structure and the stability of its classification taxonomy. OBJECTIVES To determine whether empirical summary scales could be ...

BACKGROUND The myocardial performance index (MPI) first described by Chuwa Tei in 1995 is a relatively new echocardiographic variable used for assessment of overall cardiac function. Previous studies have demonstrated the MPI to be a sum representation of both left ventricular systolic and diastolic function with prognostic value in patients with coronary artery disease as well as symptomatic h...

Initial versions of MPI were designed to work efficiently on multi-processors which had very little job control and thus static process models. Subsequently forcing them to support a dynamic process model suitable for use on clusters or distributed systems would have reduced their performance. As current HPC collaborative applications increase in size and distribution the potential levels of no...

Manufacturing process innovation (MPI), an organization-wide effort involving radical redesign of manufacturing related processes and systems to achieve dramatic improvements in critical manufacturing performance measures, encompasses various kinds of activities. Some MPI initiatives focus on technological innovation and others may intend to change work processes and ganizations adopt new techn...
