Endpoints is a topic under discussion within the MPI forum [3] that proposes to introduce a new communicator creation function that creates a communicator with multiple ranks for each MPI process in a parent communicator. In this talk we will discuss our initial implementation of endpoints in our research MPI library, called EMPI4Re. The Exascale MPI library for Research (the EMPI4Re library) i...

This study was conducted in the sea system of Taranto (south Italy) to explore consequences COVID-19 lockdown all human activities on zooplankton abundance and composition. Copepoda were selected as best indicators four different dates taken represent annual variability. The availability samples from past collections (15 30 years ago) allowed comparison with previous situations. community most ...

conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...

BACKGROUND Positron emission tomography (PET) myocardial perfusion imaging (MPI) offers technical benefits compared with single photon emission computed tomography (SPECT) MPI, but there has been no systematic comparison of their diagnostic accuracy for coronary artery disease. We performed a bivariate meta-analysis of the published literature to compare the sensitivity and specificity of PET v...

MPI for Python (mpi4py) has evolved to become the most used binding message passing interface (MPI). We report on various improvements and features that mpi4py gradually accumulated over past decade, including support up MPI-3.1 specification, CUDA-aware implementations, other utilities at intersection of MPI-based parallel distributed computing application development.

Toxoplasma gondii reportedly manipulates rodent behaviour to increase transmission to its definitive feline host. We compared the effects of mouse infection by two Type II strains of T. gondii, Prugniaud (PRU) and ME49, on attraction to cat odour, locomotor activity, anxiety, sensorimotor gating, and spatial working and recognition memory 2 months post-infection (mpi). Attraction to cat odour w...

Component architectures provide a useful framework for developing an extensible and maintainable code base upon which largescale software projects can be built. Component methodologies have only recently been incorporated into applications by the High Performance Computing community, in part because of the perception that component architectures necessarily incur an unacceptable performance pen...

MPI has been extremely successful. In areas like e.g. particle physics most of the available parallel programs are based on MPI. Unfortunately, they must be run in dedicated clusters or parallel machines, being unable to use for long running applications the growing pool of idle time of general-purpose desktop computers. Additionally, MPI offers a quite low level interface, which is hard to use...
