    Checkpointing is the predominant storage driver in today's petascale supercomputers and is expected to remain as such in tomorrow's exascale supercomputers. Users typically prefer to checkpoint into a shared file yet parallel file systems often perform poorly for shared file writing. A powerful technique to address this problem is to transparently transform shared file writing into many exclusivel... View full abstract»

  • Compressing Intermediate Keys between Mappers and Reducers in SciHadoop

    In Hadoop mappers send data to reducers in the form of key/value pairs. The default design of Hadoop's process for transmitting this intermediate data can cause a very high overhead, especially for scientific data containing multiple variables in a multi-dimensional space. For example, for a 3D scalar field of a variable “windspeed1” the size of keys was 6.75 times the size of values... View full abstract»

    Today's network file systems consist of a variety of complex subprotocols and backend storage classes. The data is typically spread over multiple data servers to achieve higher levels of performance and reliability. A metadata server is responsible for creating the mapping of a file to these data servers. It is hard to map application specific access patterns to storage system specific features, w...

    Many I/O- and data-intensive scientific applications use parallel I/O software to access files in high performance. On modern parallel machines, the I/O software consists of several layers, including high-level libraries such as Parallel netCDF and HDF, middleware such as MPI-IO, and low-level POSIX interface supported by the file systems. For the I/O software developers, ensuring data flow is imp... View full abstract»

    Today's server environments consist of many machines constructing clusters for distributed computing system or storage area networks (SAN) for effectively processing or saving enormous data. In these kinds of server environments, backend-storages are usually the bottleneck of the overall system. But it is not enough to simply replace the devices with better ones to exploit their performance benefi... View full abstract»

  • A Case for Scaling HPC Metadata Performance through De-specialization

    Lack of a highly scalable and parallel metadata service is the Achilles heel for many cluster file system deployments in both the HPC world and the Internet services world. This is because most cluster file systems have focused on scaling the data path, i.e. providing high bandwidth parallel I/O to files that are gigabytes in size. But with proliferation of massively parallel applications that pro... View full abstract»

  • An Evolutionary Path to Object Storage Access

    High-performance computing (HPC) storage systems typically consist of an object storage system that is accessed via the POSIX file interface. However, rapid increases in system scales and storage system complexity have uncovered a number of limitations in this model. In particular, applications and libraries are limited in their ability to partition data into units with independent concurrency con... View full abstract»

    As applications become more complex, and the level of concurrency in systems continue to rise, developers are struggling to scale complex data models on top of a traditional byte stream interface. Middleware tailored for specific data models is a common approach to dealing with these challenges, but middleware commonly reproduces scalable services already present in many distributed file systems. ...

  • A Case for Optimistic Coordination in HPC Storage Systems

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (497 KB) | HTML iconHTML

    High-performance computing (HPC) storage systems rely on access coordination to ensure that concurrent updates do not produce incoherent results. HPC storage systems typically employ pessimistic distributed locking to provide this functionality in cases where applications cannot perform their own coordination. This approach, however, introduces significant performance overhead and complicates faul... View full abstract»

    Workflow management systems (WMS) are typically comprised of or make use of multiple independent software components. The design and development of those components is typically drawn from functional requirements of scientific applications that utilize the corresponding WMS. Consequently, the WMS design reflects those core functional requirements in applications that it supports in the future. Whe... View full abstract»
