I am a Senior Research Associate
in the Department of
and Engineering at the Ohio State
University, since Nov, 2014.
My research advisor is Prof. Dhabaleswar
K. (DK) Panda.
I am a member of Network Based
My research interests include parallel programming models, parallel systems, distributed systems and heterougeneous HPC architectures including GPUs and MIC coprocessors. From 2012 to 2014, I held a Post-doctoral researcher position within the same team
Before that I was a post-doctoral researcher with the HP2 team (High Performance and Parallel) at Telecom Sud-Paris, Evry. In the area of compilation/ code generation for parallel architectures, I work on both the optimization of the source to source transformation tool (STEP) and its port on manycores architectures.
I defended my PhD thesis at the LRI- Laboratoire de Recherche en Informatique (
Parall Team ) in November 2011 on parallel computing and parallel architectures. My thesis work (dissertation available here), led by Prof Daniel Etiemble and Dr Joel Falcou , focused on a programming model and deployment / hybrid code generation for hierarchical and heterogeneous parallel architectures (with development of tools).
In September 2008, I graduated from University of Paris-Sud 11 with a Master's degree in Computer Science.

The MVAPICH2 software, supporting MPI 3.0 standard, delivers best performance,
scalability and fault tolerance for high-end computing systems and servers using
InfiniBand, 10GigE/iWARP and RoCE networking technologies. The MVAPICH2-X software package provides support for hybrid MPI+PGAS (UPC and OpenSHMEM)
programming models with unified communication runtime for emerging exascale
systems. The MVAPICH2-GDR package provides support for clusters with NVIDIA GPUs
supporting the GPUDirect RDMA feature. The MVAPICH2-MIC package provides support
for clusters with Intel MIC coprocessors. MVAPICH2 software is powering several
supercomputers in the TOP 500 list.
- BSP++ Library
Is a generic library using C++ templates. Based on a hierarchical model, the BSP++ library takes the hybrid architectures (Multicore clusters and Cell BE accelerator based clusters) as native targets. Using a small set of primitives and intuitive concepts, BSP++ provides a simple way to program hybrid and heterogeneous architectures. It generates MPI, OpenMP, MPI+OpenMP, Cell BE and MPI+Cell BE codes with the same version of the user base code (the choice of the target machine is just a preprocessing symbole).
- BSPGen FrameWork
Is a tool for an automatic hybrid multi-level hierarchy (MPI + OpenMP or MPI +Cell BE) code generation. Using the BSP++ cost model, BSPGen predicts and generates the
appropriate hierarchical hybrid code (BSP++ code) for a given application on a target architecture. The prediction is based on a new pass on the LLVM compiler. BSPGen generates hybrid code from a list of sequential functions and a description of the parallel algorithm (XML file).
