Program master-slave

We show in Figs. 2 and 3 the speed up for a Davidson iteration obtained with the PVM [17] ( Parallel Virtual Machine ) and PVMe [18] ( PVM enhanced ) message passing interfaces respectively. Speed-up factors are here relative to the sequential version of the program (n=l), and the theoretical mciximum has been defined according to the expression s n) — n — I appropriate to the used master/slave model. 

The VMC and DMC methods are implemented in the casino code [44] (version 3.0), with which we intend to carry out this project. CASINO is written in Fortran 95 and parallelised using MPI with a master/slave program model, casino has been in existence for more than thirteen years and has been used on a wide variety of high-performance computer platforms. There are 360 registered users of the code. CASINO requires only the MPI library. 

Most CMOS setup programs will display all the IDE buses and which devices are connected in which positions. You can check which bus and which designation (master or slave) a device is configured for by using "View drive setup" (or similar) in your computer s setup program. 

The model - nature itself - uses parallel structures in generational parent-to-child succession. As a result, it makes sense to apply this parallelity to the structure in the optimization program system as well. The EVOBOX code works on the processor as a so-called master and is responsible for mutations and selections, while other processors configured as slaves have to compute the quality functions of the different individuals.
