In this paper we examine the topic of writing fault-tolerant Message Passing Interface (MPI) applications. We discuss the meaning of fault tolerance in general and what the MPI Standard has to say about it. We survey several approaches to this problem, namely checkpointing, restructuring a class of standard MPI programs, modifying MPI semantics, and extending the MPI specification. We conclude ...
BACKGROUND Electromechanical discoordination may contribute to long-term pulmonary right ventricular (RV) dysfunction in patients after surgery for congenital heart disease. We sought to evaluate changes in RV function after temporary RV cardiac resynchronization therapy. METHODS AND RESULTS Twenty-five patients aged median 12.0 years after repair of tetralogy of Fallot and similar lesions we...
This paper examines the topic of writing fault-tolerant MPI applications. We discuss the meaning of fault tolerance in general and what the MPI Standard has to say about it. We survey several approaches to this problem, namely checkpointing, restructuring a class of standard MPI programs, modifying MPI semantics, and extending the MPI specification. We conclude that within certain constraints, ...
Chiral 2-methylpiperidine (2-MPI) is an important building block that has potential for applications in pharmaceuticals and pesticides. In this study, we observed the hydrolase Arthrobacter sp. K5 exhibits high (S)-selectivity toward rac-N-pivaloyl-2-MPI to yield (S)-2-MPI with 80.2% enantiomeric excess (ee) a 38.2% conversion. The hydrolase, which was identified by analyses of partial amino ac...
INTRODUCTION Globally, rotavirus (RV) is the leading cause of gastroenteritis (GE) in children. Longitudinal data about changes in RV genotype distribution and vaccine effectiveness (VE) are scarce. This study was conducted in Lebanon over 3 consecutive RV seasons to estimate the rate of RVGE hospitalization, identify RV genotypes, determine the seasonal and geographical variations, and calcula...
Of the more than 150 human rhinovirus (RV) serotypes, 89 utilize intercellular adhesion molecule-1 (ICAM-1) for cell entry. These belong either to species A or B. We recently demonstrated that RV-B14 and RV-A89, despite binding this same receptor, are routed into distinct endosomal compartments for release of their RNA into the cytosol. To gain insight into the underlying mechanism we now compa...
A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...
Purpose The purpose of this study was to investigate the effects prosthetic interventions in patients with Kennedy Class ? (unilateral missing posterior teeth) on mastication predominance.Methods subjects comprised II and healthy dentate volunteers (HD group). were asked freely chew test foods (chewing gum, beef jerky, peanuts). Electromyographic activity bilateral masseter muscles recorded twi...
MPI accomplishes portable, standardized message-passing between processes by exposing a standard API that hides the implementation of the underlying mechanism for message passing. Until now, checkpointing an MPI program required knowledge of these underlying mechanisms. Through the addition of a proxy, we demonstrate that MPI programs can be checkpointed and restarted regardless of the MPI impl...
