SciPy 2019: How to Accelerate an Existing Codebase with Numbastan_seibert
The document discusses a four step process for accelerating existing code with Numba: 1) Make an honest self-inventory of why speeding up code is needed, 2) Perform measurement of code through unit testing and profiling, 3) Refactor code following rules like paying attention to data types and writing code like Fortran, 4) Share accelerated code with others by packaging with Numba as a dependency. Key rules discussed include always using @jit(nopython=True), paying attention to supported data types, writing functions over classes, and targeting serial execution first before parallelism.
Numba is a just-in-time compiler for Python that can optimize numerical code to achieve speeds comparable to C/C++ without requiring the user to write C/C++ code. It works by compiling Python functions to optimized machine code using type information. Numba supports NumPy arrays and common mathematical functions. It can automatically optimize loops and compile functions for CPU or GPU execution. Numba allows users to write high-performance numerical code in Python without sacrificing readability or development speed.
Numba is a Python compiler that uses type information to generate optimized machine code from Python functions. It allows Python code to run as fast as natively compiled languages for numeric computation. The goal is to provide rapid iteration and development along with fast code execution. Numba works by compiling Python code to LLVM bitcode then to machine code using type information from NumPy. An example shows a sinc function being JIT compiled. Future work includes supporting more Python features like structures and objects.

MPI Sessions: a proposal to the MPI ForumJeff Squyres
This document discusses proposals for improving MPI (Message Passing Interface) to allow for more flexible initialization and usage of MPI functionality. The key proposals are:
1. Introduce the concept of an "MPI session" which is a local handle to the MPI library that allows multiple sessions within a process.
2. Query the underlying runtime system to get static "sets" of processes and create MPI groups and communicators from these sets across different sessions.
3. Split MPI functions into two categories - those that initialize/query/destroy objects and those for performance-critical communication/collectives. The former category would initialize MPI transparently.
4. Remove the requirement for MPI_Init() and MPI
The document discusses running IEEE 802.15.4 low-power wireless networks under Linux. It describes the linux-wpan project, which provides native support for 802.15.4 radio devices and the 6LoWPAN standard in the Linux kernel. It also discusses the wpan-tools userspace utilities. The document outlines how to set up basic communication between Linux, RIOT and Contiki operating systems for IoT devices using the virtual loopback driver or USB dongles. It also covers link layer security, IPv6 routing protocols like RPL, and areas for future work such as mesh networking support.

ARB_gl_spirv: bringing SPIR-V to Mesa OpenGL (FOSDEM 2018)Igalia
By Alejandro Piñeiro.
Since OpenGL 2.0, released more than 10 years ago, OpenGL has been using OpenGL Shading Language (GLSL) as a shading language. When Khronos published the first release of Vulkan, almost 2 years ago, shaders used a binary format, called SPIR-V, originally developed for use with OpenCL.
That means that the two major public 3D graphics API were using different shading languages, making porting from one to the other more complicated. Since then there were efforts to allow making this easier.
On July 2016, the extension ARBglspirv was approved by Khronos, that allows a SPIR-V module to be specified as containing a programmable shader stage, rather than using GLSL, whatever the source language was used to create the SPIR-V module. This extension is now part of OpenGL 4.6 core, making it mandatory for any driver that wants to support this version.
This talk introduces the extension, what advantages provides, and explain how it was implemented for the Mesa driver.

Typically, Python software engineers don’t necessarily care about how the language handles memory. However, sometimes it’s very useful to understand what’s going on under the hood. In this talk, I’ll give you a brief overview of how Python manages memory and some useful tips and tricks that you may not already know.
When working with big data or complex algorithms, we often look to parallelize our code to optimize runtime. By taking advantage of a GPUs 1000+ cores, a data scientist can quickly scale out solutions inexpensively and sometime more quickly than using traditional CPU cluster computing. In this webinar, we will present ways to incorporate GPU computing to complete computationally intensive tasks in both Python and R.

The Why and How of HPC-Cloud Hybrids with OpenStack - Lev Lafayette, Universi...OpenStack
Audience Level
Intermediate
Synopsis
High performance computing and cloud computing have traditionally been seen as separate solutions to separate problems, dealing with issues of performance and flexibility respectively. In a diverse research environment however, both sets of compute requirements can occur. In addition to the administrative benefits in combining both requirements into a single unified system, opportunities are provided for incremental expansion.
The deployment of the Spartan cloud-HPC hybrid system at the University of Melbourne last year is an example of such a design. Despite its small size, it has attracted international attention due to its design features. This presentation, in addition to providing a grounding on why one would wish to build an HPC-cloud hybrid system and the results of the deployment, provides a complete technical overview of the design from the ground up, as well as problems encountered and planned future developments.
Speaker Bio
Lev Lafayette is the HPC and Training Officer at the University of Melbourne. Prior to that he worked at the Victorian Partnership for Advanced Computing for several years in a similar role.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

9. A word on Caffe2
How is Caffe2 different from PyTorch?
Caffe2 is built to excel at mobile and at large scale deployments. While it is new in Caffe2 to support
multi-GPU, bringing Torch and Caffe2 together with the same level of GPU support, Caffe2 is built to
excel at utilizing both multiple GPUs on a single-host and multiple hosts with GPUs.
PyTorch is great for research, experimentation and trying out exotic neural networks, while
Caffe2 is headed towards supporting more industrial-strength applications with a heavy focus
on mobile.
This is not to say that PyTorch doesn’t do mobile or doesn’t scale or that you can’t use Caffe2 with
some awesome new paradigm of neural network, we’re just highlighting some of the current
characteristics and directions for these two projects. We plan to have plenty of interoperability and
methods of converting back and forth so you can experience the best of both worlds.

19. About ONNX
ONNX is a community project created by Facebook and Microsoft. We believe there is a need for
greater interoperability in the AI tools community. Many people are working on great tools, but
developers are often locked in to one framework or ecosystem.
ONNX provides a definition of an extensible computation graph model, as well as definitions of built-
in operators and standard data types.
Operators are implemented externally to the graph, but the set of built-in operators are portable
across frameworks. Every framework supporting ONNX will provide implementations of these
operators on the applicable data types.
23. An Open Source neural networks library
• Written in Python
• Running on top of TensorFlow, CNTK & Theano
• Can be run on CPU and GPU
• Supports CNN and RNN, as well as combinations of the two
…built for fast experimentation
• User friendliness: designed for human beings, not machines! Consistent and simple API
• Modularity: models are sequences or graphs of standalone modules that can be plugged
together
• Extensibility: new modules are simple to add (as new classes and functions)
• Work with Python: models are described in Python code and are compact, easy to debug and
easy to extend
25. Keras has a lot of built in layers
• Dense layer of neural network
• Common activation functions like linear, sigmoid, tanh, ReLU, …
• Dropout, L1/L2 regularizers
• Convolutional layers (Conv1D, Conv2D, Conv3D, …)
• Pooling layers
• Recurrent layers (fully connected RNN, LTSM, …)
All these layers can be tuned, and you can add custom layers by extending existing ones or writing
new Python classes.
28. Training the model
• Models are trained on Numpy arrays
• Input data and labels must be passed to the fit method of the model
• The number of epochs is fixed (number of iterations on the dataset)
• Validation set can be provided to the fit method (for evaluation of loss and metrics)
At the end of the training, fit will return an history of metrics and training loss values at each epochs.
31. Integration with
Scikit-Learn
Keras provides wrappers which
can be used from Scikit-Learn
pipelines.
It allows to use a Keras
Sequential model as a classifier
or regressor in Scikit-Learn
32. Keras functional API
The Keras functional API is the
way to go for defining complex
models, such as multi-output
models, directed acyclic
graphs, or models with shared
layers.
With the functional API, all
models can be called as if it
where a layer. It’s easy to
reused trained models in a
larger pipeline.
