With the increasing number of Cloud offers and their heterogeneity , it becomes harder and harder for the Cloud Users to select the proper cloud(s) and resources.
Moreover, the selection process is strongly related to the application itself and the users' requirements (deadline, cost, etc.).
In this talk, we will present our early work on selecting and provisioning Virtual Machines in Federated Clouds. Our current work focuses on running Bag Of Tasks.
We will show our Cloud Broker Simulator based on SimGrid and how it can be used to help selecting resources for a given application based on a set of requirements.
Finally, we will conclude on presenting the future challenges such as taking into account a large set of scientific computing applications such as workflows.Rouzaud-Cornabas Jonathan

The Data-Dependence graph of Adjoint Codes
Automatic Differentiation (AD) is the primary means of obtaining analytic derivatives from a numerical model given as a computer program. Therefore, it is an essential productivity tool in numerous computational science and engineering domains. Computing gradients with the adjoint mode of AD via source transformation is a particularly beneficial but also challenging use of AD. From another viewpoint, Data-Dependence Graphs are one of the key tools to study and improve the performance of programs, particularly in view of their parallel execution. Basic parallelizability properties are classically expressed as properties of the Data-Dependence Graph of a code. We explore the relation between the Data-Dependence graphs of a program and of its adjoint, thus explaining why many parallel properties of a code also apply to its adjoint.

A One-Sided View of HPC: Global-View Models and Portable Runtime Systems
Global-view and one-sided parallel programming models provide a promising alternative to conventional approaches by enabling programmers to aggregate the memory of multiple nodes and allowing them to access any data, regardless of its physical location. This model for asynchronous data movement also decouples synchronization from communication, enabling a greater degree of asynchrony. These properties are of critical importance to scientific computing applications, which must cope with rapidly evolving system architectures, and where new simulation and analysis techniques have exposed greater sparsity and computational imbalance.
In this talk, I will present recent and ongoing work on portable one-sided communication interfaces and global-view parallel programming systems. This work focuses on the evolution of the MPI-2 remote memory access (RMA) communication interface into the new MPI-3 RMA interface, and on the utilization of these interfaces to support higher-level parallel programming interfaces. I will describe work, in which we have used the MPI RMA interface to provide the first portable, one-sided implementation of Global Arrays and its impact on the NWChem computational chemistry suite. In addition, I will describe current and ongoing work in the deployment, implementation, and performance tuning of MPI-3 RMA.
