The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in defense and security, nuclear and renewable energies, technological research for industry, and fundamental research in the physical sciences and life sciences. Based in Saclay (Paris region, France), List Institute is one of CEA three technological research institutes dedicated to smart digital systems.
The following PhD position is currently open to application: Unifying Distributed Memories in Heterogeneous Systems Future computers in high-performance and embedded systems lead to complex memory hierarchies. Hundreds of computing nodes will have to be connected to tera-bytes of memories. In such systems, both the processing units (CPU, GPU, DSP, FPGA) and the memories (DRAM, NVRAM, FLASH) can be heterogeneous. Several architectures exist (distributed memory, shared memory, NUMA) with different hardware implementations (cache coherence, communication protocols), software implementations (thread parallelism, OpenMP, transactions) and communication technologies between processing units and memory (MPI, RDMA, RoCE, CCIX, GenZ). None of the approaches above offer a simple, unified programming model and memory model for parallel applications. The purpose of this Ph.D. Thesis is to study the possibility of using emerging technologies related to computing units, hybrid memories (persistent or not) and remote communication standards in order to accelerate data sharing onto heterogeneous platforms and provide a convenient programming model. http://www-instn.cea.fr/formations/formation-par-la-recherche/doctorat/liste-des-sujets-de-these/unification-des-memoires-reparties-dans-les-systemes-heterogenes,18-0290.html Thesis director: Henri-Pierre CHARLES CEA DRT/DACLE/LIALP-LIST MINATEC Campus 17 rue des Martyrs 38054 Grenoble Cedex 9 Supervisor: Loïc CUDENNEC CEA DRT/DACLE/LCE CEA, LIST, Nano-INNOV / Saclay PC 172, 91191 Gif-sur-Yvette CEDEX Phone number: +33 1 69 08 00 58 Email: loic.cuden...@cea.fr Hosting lab: Département Architectures Conception et Logiciels Embarqués (LIST-LETI) Laboratoire Calcul Embarqué (Embedded Computing Laboratory) CEA Saclay, France Expected starting date: 01/10/2018 _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
