Using the Message Passing Interface (MPI) in C++ has been difficult to this point because of the lack of suitable C++ bindings and C++ class libraries. The existing MPI standard provides language bindings only for C and Fortran 77, precluding their direct use in object oriented programming. Even the proposed C++ bindings in MPI-2 are at a fairly low-level and are not directly suitable for objec...

The message passing interface (MPI) is a standard used by many scientific applications. It has the advantage of a smoother migration path for porting applications to the Grid. In this paper Grid-enabled tools and libraries for developing MPI applications are presented. The first is PACX-MPI, an implementation of the MPI standard optimized for Grid environments. The second is MARMOT, a tool that...

Message Passing Interface (MPI) is the most commonly used paradigm in writing parallel programs since it can be employed not only within a single processing node but also across several connected ones. Data flow analysis concepts, techniques and tools are needed to understand and analyze MPI-based programs to detect bugs arise in these programs. In this paper we propose two automated techniques...

Beller et al. showed in the “anginal cascade”(1) that, with increasing stress time and myocardial oxygen demand, ischemic ST depression and anginal symptoms appear after fl ow heterogeneity, regional myocardial dysfunction, signifi cant perfusion defects and global left ventricular dysfunction. This accounts for the increased sensitivity, specifi city and accuracy of MPI over symptoms and stres...

BACKGROUND Myocardial perfusion imaging (MPI) provides highly valuable information for risk stratification and determination of optimal clinical management. The goal of the present study was to assess the prognostic value of myocardial perfusion SPECT for the prediction of future cardiac events in Asian population. METHODS Five hundred and ten consecutive patients, who had undergone myocardia...

Stress-induced cardiomyopathy, triggered by acute catecholamine discharge, is a syndrome characterized by transient, apical ballooning linked to acute heart failure and ventricular arrhythmias. Rats receiving an acute isoproterenol (ISO) overdose (OV) suffer cardiac apex ischemia-reperfusion damage and arrhythmia, and then undergo cardiac remodeling and dysfunction. Nevertheless, the subcellula...

BACKGROUND The West-Haven Multidimensional Pain Inventory (MPI) can be used to describe behavioural and psychosocial consequences of long-term pain but little is known about how MPI items and MPI subgroups relate to goals that patients find important in rehabilitation. Life satisfaction measured by the LiSat-11 checklist can be defined as an individual's perception of the difference between his...

Aim: To evaluate the presence of myocardial ischemia in asymptomatic patients with intermediate and high cardiovascular (CV) risk without previously known coronary artery disease (CAD) and the value of ischemia on therapeutic decision and prognosis. Materials and methods: 75 asymptomatic patients (35 with intermediate and 40 patients with high CV risk-SCORE risk system), underwent SPECT myocard...

In April of 1992, a group of parallel computing vendors, computer science researchers, and application scientists met at a one-day workshop and agreed to cooperate on the development of a community standard for the message-passing model of parallel computing. The MPI Forum that eventually emerged from that workshop became a model of how a broad community could work together to improve an import...
