An MPI Version of the BLACSyD
نویسنده
چکیده
In this paper, issues related to implementing an MPI version of the Basic Linear Communication Sub-programs (BLACS) are investigated. A set of routines, the MPI Linear Algebra Communication Subprograms (MLACS), are presented, and these are used to implement an MPI version of the BLACS. The MLACS provide the same functionality as the BLACS, but extend the functionality of the BLACS to include both blocking and nonblocking communication, and all four of the MPI communication modes.

Doppler-derived myocardial performance index (MPI) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. The goal of this study was to define normal values of right ventricular MPI in neonates in the first 48 to 72 hours of life. Fifty-one...
متن کاملMPI- and CUDA- implementations of modal finite difference method for P-SV wave propagation modeling
Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...
متن کاملDetermining Malmquist Productivity Index in DEA and DEA-R based on Value Efficiency
Malmquist Productivity Index (MPI) is a numeric index that is of great importance in measuring productivity and its changes. In recent years, tools like DEA have been utilized for determining MPI. In the present paper, some models are recommended for calculating MPI when there are just ratio data available. Then, using DEA and DEA-R, some models are proposed under the constant returns to scale ...
