DAGR is a scalable framework for implementing analysis pipelines using parallel design patterns. DAGR abstracts the pipeline concept into a state machine composed of connected algorithmic units. Each algorithmic unit is written to do a single task resulting in highly modularized, reusable code. DAGR provides infrastructure for control, communication, and parallelism, you provide the kernels to implement your analyses. Written in modern C++ and designed to leverage MPI+threading for parallelism, DAGR can leverage the latest HPC hardware including many-core architectures and GPUs. The framework supports a number of parallel design patterns including distributed data, map-reduce, and task based parallelism.
DIY is a block-parallel library for implementing scalable algorithms that can execute both in-core and out-of-core. The same program can be executed with one or more threads per MPI process, seamlessly combining distributed-memory message passing with shared-memory thread parallelism. The abstraction enabling these capabilities is block parallelism; blocks and their message queues are mapped onto processing elements (MPI processes or threads) and are migrated between memory and storage by the DIY runtime. Complex communication patterns, including neighbor exchange, merge reduction, swap reduction, and all-to-all exchange, are possible in- and out-of-core in DIY.
Henson uses coroutines and position-independent executables to enable cooperative multitasking between simulation and analysis, allowing the same executables to post-process simulation output, as well as to process it on the fly, both in situ and in transit. Our design differs significantly from the existing frameworks and offers an efficient and robust approach to integrating multiple codes on modern supercomputers.
The SENSEI generic data interface provides a framework for science code teams and analysis algorithm developers to write code once and use it anywhere within the four major in situ analysis frameworks (ADIOS, GLEAN, ParaView/Catalyst and VisIt/libsim). Furthermore, since ParaView/Catalyst and VisIt/Libsim both are treated as analysis routines under SENSEI, these visualizations can be run in situ, or in transit using ADIOS or GLEAN transparently.
TECA is a collection of climate analysis algorithms geared toward extreme event detection and tracking implemented in a scalable parallel framework. The core is written in modern C++ and uses MPI+thread for parallelism. The framework supports a number of parallel design patterns including distributed data parallelism and map-reduce. Python bindings make the high performance c++ code easy to use. TECA has been used up to 750k cores.
The LBNL BrainFormat library specifies a general data format standardization framework and implements a novel file format for management and storage of neuro-science data. The library provides a number of core modules that can be used for implementation and specification of scientific application formats in general. Based on these components, the library implements the LBNL BRAIN file format.
H5hut (formerly H5Part) is a very simple data storage schema and provides an API that simplifies the reading/writing of the data to the HDF5 file format. H5Part is built on top of the HDF5 (Hierarchical Data Format).
Neurodata Without Borders: Neurophysiology (NWB:N) is more than just a file format but it defines an ecosystem of tools, methods, and standards for storing, sharing, and analyzing complex neurophysiology data. PyNWB is a Python package for working with NWB:N files. It provides a high-level API for efficiently working with Neurodata stored in the NWB:N format. Beyond neurophysiology, PyNWB provides a general set of tools for hierarchical organization of data for creation of complex data standards.
Brain Modulyzer is an interactive visual exploration tool for functional magnetic resonance imaging (fMRI) brain scans, aimed at analyzing the correlation between different brain regions when resting or when performing mental tasks. Integrated methods from graph theory and analysis, such as community detection and derived graph measures, make it possible to explore the modular and hierarchical organization of functional brain networks.
ECoG ClusterFlow is an interactive visual analysis tool for the exploration of high-resolution Electrocorticography (ECoG) data. ECoG Clusterflow detects and visualizes dynamic high-level structures, such as communities, using the time-varying spatial connectivity network derived from high-resolution ECoG data. ECoG ClusterFlow makes it possible 1) to compare the spatio-temporal evolution patterns for continuous and discontinuous time-frames, 2) to aggregate data to compare and contrast temporal information at varying levels of granularity, 3) to investigate the evolution of spatial patterns without occluding the spatial context information.
OpenMSI is an advanced web-based gateway for management and storage of MSI data, the visualization of the hyper-dimensional contents of the data, and the statistical analysis.
OpenMSI Arrayed Analysis Toolkit (OMAAT) is a new software package to analyze spatially defined samples in mass spectrometry imaging (MSI) using OpenMSI and Jupyter.

The semViewer software was developed as part of an LBNL LDRD project during the period 1999-2001. It is used to perform distance and angular measurements of perceived 3D objects present in pairs of images obtained from scanning electron microscopy.
F3D is a Fiji plugin, designed for high-resolution 3D image, and written in OpenCL. F3D plugin achieves platform-portable parallelism on modern multi-core CPUs and many-core GPUs. The interface and mechanisms to access F3D accelerated kernes are written in Java to be fully integrated with other tools available within Fiji/ImageJ. F3D delivers several key image-processing algorithms necessary to remove artifacts from micro-tomography data. The algorithms consist of data parallel aware filters that can efficiently utilize resources and can process data out of core and scale efficiently across multiple accelerators. Optimized for data parallel filters, F3D streams data out of core to efficiently manage resources, such as memory, over complex execution sequence of filters. This has greatly expedited several scientific workflows dealing with high-resolution images. F3D preforms two main types of 3D image processing operations: non-linear filtering, such as bilateral and median filtering, and morphological operators (MM) with varying 3D structuring elements.

zorder-lib is a C-language library callable from C or C++ programs that provides a simple-to-use API for implementing an altnerative to traditional row-major order in-memory layout, one based on a Morton-order space-filling curve (SFC), specifically, a Z-order variant of the Morton order curve. The library enables programmers to, after a simple initialization step, to convert a multidimensional array from row-major to Z-order layouts, then use a single, generic API call to access data from any arbitrary (i,j,k) location from within the array, whether it it be stored in row-major or z-order format.
