In this paper we present a study on the time cost added to the grid computing as a result of the use of a coordinated checkpoint / recovery fault tolerance protocol, we aim to find a mathematical model which determined the suitable time to save the checkpoints for application, to achieve a minimum finish time of parallel application in grid computing with faults and fault tolerance protocols, we have find this model by serial modeling to the goal errors, execution environment and the chosen fault tolerance protocol all that by Kolmogorov differential equations.

In this paper, we introduce a continuous mathematical model to
optimize the compromise between the overhead of fault tolerance
mechanism and the faults impacts in the environment of
execution. The fault tolerance mechanism considered in this
rese
arch is a coordinated checkpoint/recovery mechanism and the
study based on stochastic model of different performance critics of
parallel application on parallel and distributed environment.
In this research, We introduce two probabilistic mechanisms to
certificate parallel applications on distribute architecture supposing
that there are no oracles on which we depend on certification, in
addition to introducing cost model of two mecha
nisms and compare
them.
In this research, we are interested in parallel applications, which
are represented by data-flow graph that is built dynamically during
the execution and which are executed in a wide distributed
heterogeneous and dynamic environment and these applications
use the principle of work stealing to distribute the tasks among the
processors.
In this work, we present programming solutions for some nonlinear partial differential equations, which are the advection equation, the third-order KdV
equations, and a family of Burgers' equations.
Overlay multicast (Application-Level Multicast (ALM)) constructs a multicast delivery tree among end hosts. Unlike traditional IP multicast where the internal tree nodes are dedicated routers which are relatively stable and do not leave the multicast
tree voluntarily, the non-leaf nodes in the overlay tree are free end hosts which can join/leave the overlay at will, or even crash without notification. So, the leaving node can leave suddenly and cannot give its descendants (and the Rendez-vous Point (RP)) the time to prepare the recovering (the reconnection) of the overlay tree, and so there is a need to trigger a rearrangement process in which each one of its descendants should rejoin the overlay tree. In this case, all of its downstream nodes are partitioned from the overlay tree and cannot get the multicast data any more. These dynamic characteristics cause the instability of the overlay tree, which can significantly impact the user.
A key challenge in constructing an efficient and resilient ALM protocol is to provide fast data recovery when overlay node failures partition the data delivery paths. In this paper, we analyze the performance of the ALM tree recovery solutions using different metrics.
We introduce an auto adaptive strategy enables to write a parallel
algorithm adapts to the number of available resources at allocated
parallel environment to execute the parallel program. The parallel
applications we are studying which are represe
nted by data-flow
graph which built dynamically during the execution. The new
suggested strategy is based on coupling of a sequential algorithm
and a parallel one and relies on the principle of work stealing in
the tasks scheduling. We offer a study of the complexity of the
adaptive algorithm and analyze its performance on processors
and compare it with a performance of a classic parallel algorithm.
