The objective of this project is to construct a service that will allow for past and present un-curated data to be utilized by science while simultaneously demonstrating the novel science that can be conducted from such data. The proposed effort will focus on the large distributed and heterogeneous bodies of past and present un-curated data, what is often referred to in the scientific community as long-tail data, data that would have great value to science if its contents were readily accessible. The proposed framework will be made up of two re-purposable cyberinfrastructure building blocks referred to as a Data Access Proxy (DAP) and Data Tilling Service (DTS). These building blocks will be developed and tested in the context of three use cases that will advance science in geoscience, biology, engineering, and social science. The DAP will aim to enable a new era of applications that are agnostic to file formats through the use of a tool called a Software Server which itself will serve as a workflow tool to access functionality within 3rd party applications. By chaining together open/save operations within arbitrary software the DAP will provide a consistent means of gaining access to content stored across the large numbers of file formats that plague long tail data. The DTS will utilize the DAP to access data contents and will serve to index unstructured data sources (i.e. instrument data or data without text metadata). Building off of the Versus content based comparison framework and the Medici extraction services for auto-curation the DTS will assign content specific identifiers to untagged data allowing one to search collections of such data. The intellectual merit of this work lies in the proposed solution which does not attempt to construct a single piece of software that magically understands all data, but instead aims at utilizing every possible source of automatable help already in existence in a robust and provenance preserving manner to create a service that can deal with as much of this data as possible. This proverbial “super mutt” of software, or Brown Dog, will serve as a low level data infrastructure to interface with digital data contents and through its capabilities enable a new era of science and applications at large. The broader impact of this work is in its potential to serve not just the scientific community but the general public, as a DNS for data, moving civilization towards an era where a user’s access to data is not limited by a file’s format or un-curated collections.

We will present our last result on the SMPI/SimGrid framework. SMPI now implements all the collective algorithms and selection logics of both OpenMPI and MPICH and even a few other collective algorithms from Star MPI. Together with a flexible network model and topology description mechanisme, this allowed us to obtain almost perfect prediction of NASPB and BigDFT on Ethernet/TCP based clusters. We are currently working on extending this work to other kind of networks as well as on mixing the emulation capability of SMPI with the trace replay mechanism. We are also working on improving the replay mechanism so that it handles seamlessly classical trace formats.
Fault tolerance has been presented as an emerging problem for decades, with researchers often claiming that the next generation of hardware will introduce new levels of failure rates that will destroy productivity and cause applications to become unusable. While it is true that as machines have scaled, resilience has become more and more of a concern, there are issues already affecting applications at current scales. Process failure remains a concern, though primarily for applications that can run at the largest scales or on very unstable hardware. For smaller applications however, there are other concerns, such as soft errors, performance loss, etc. This talk will cover some of the research being performed in the Programming Models and Runtime Systems group at Argonne National Laboratory to study these phenomena.

Many-core architectures, such as the IBM Blue Gene/Q and Intel Xeon Phi, provide dozens of cores and hundreds of hardware threads. To utilize such architectures, application programmers are increasingly looking at hybrid programming models (frequently referred to as ``MPI+X’' models), where multiple threads interact with the MPI library. A common mode of operation for hybrid MPI+threads applications is where multiple threads are used to parallelize the computation, and one or more threads also issues MPI operations. While such a model is becoming increasingly popular because of the reducing per-core hardware resources available in modern architectures, it poses several challenges for the efficiency of MPI communication in such environments. In this talk, I’ll describe some of our recent work on optimizing MPI in such environments, either with multiple threads calling MPI operations or a single thread doing so.
