Building deep-learning models for geoscience with MATLAB and NVIDIA GPUs

Building deep learning models for geoscience using MATLAB and NVIDIA GPUs on Amazon EC2 (Part 1 of 2)

In this blog post, we discuss how geoscientists can use shallow RNN-based algorithms with MATLAB to automatically recognize distinct geologic features in seismic images. We discuss the workflow for developing the AI models using MATLAB for seismic interpretation.  In a second post will introduce the various compute resources leveraged from AWS and NVIDIA for developing the models.

AI-based drug discovery with Atomwise and WEKA Data Platform

Drug discovery is an expensive proposition, with a $2.6 billion cost over 10 years and just a 12% success rate. AI promises to significantly improve the success rate by finding small molecule hits for undruggable targets. On the forefront of using AI in drug discovery is Atomwise, with its AtomNet® platform. In this blog, we will lay out the challenges of the drug discovery process, and show how AI/ML startups are solving these challenges using solutions from Atomwise, AWS, and WEKA.

Figure 2: Identification of redun jobs and grouping them into Array Jobs to run on AWS Batch. (Top) redun represents the workflow as an Expression Graph (top-left), and identifies reductions (red boxes) that are ready to be executed. The redun Scheduler creates a redun Job (J1, J2, J3) for each reduction and dispatches those jobs to Executors based on the task-specific configuration. The Batch Executor allows jobs to accumulate for up to three seconds (default) in order to identify compatible jobs for grouping into an Array Job, which are then submitted to AWS Batch (top-right). (Bottom) As jobs complete in AWS Batch, the success (green) and failure (red) is propagated back to Executors, the Scheduler, and eventually substituted back into the Expression Graph (bottom-left).

Data Science workflows at insitro: how redun uses the advanced service features from AWS Batch and AWS Glue

Matt Rasmussen, VP of Software Engineering at insitro, expands on his first post on redun, insitro’s data science tool for bioinformatics, to describe how redun makes use of advanced AWS features. Specifically, Matt describes how AWS Batch’s Array Jobs is used to support workflows with large fan-out, and how AWS Glue’s DynamicFrame is used to run computationally heterogenous workflows with different back-end needs such as Spark, all in the same workflow definition.

Figure 1: Evaluating a sequence alignment workflow using graph reduction.** In redun, workflows are represented as an Expression Graph (left) which contain concrete value nodes (grey) and Expression nodes (blue). The redun scheduler identifies tasks that are ready to execute by finding subtrees that can be reduced (red boxes), substituting task results back into the Expression Graph (red arrows). The scheduler continues to find reductions until the Expression Graph reduces to a single concrete value (grey box, far right). If any reduction has been done before (determine by comparing an Expression's hash), the redun scheduler can replay the reduction from a central cache and skip task re-execution.

Data Science workflows at insitro: using redun on AWS Batch

Matt Rasmussen, VP of Software Engineering at insitro describes their recently released, open-source data science framework, redun, which allows data scientists to define complex scientific workflows that scale from their laptop to large-scale distributed runs on serverless platforms like AWS Batch and AWS Glue. I this post, Matt shows how redun lends itself to Bioinformatics workflows which typically involve wrapping Unix-based programs that require file staging to and from object storage. In the next blog post, Matt describes how redun scales to large and heterogenous workflows by leveraging AWS Batch features such as Array Jobs and AWS Glue features such as Glue DynamicFrame.

How to Arm a world-leading forecast model with AWS Graviton and Lambda

The Met Office is the UK’s National Meteorological Service, providing 24×7 world-renowned scientific excellence in weather, climate and environmental forecasts and severe weather warnings for the protection of life and property. They provide forecasts and guidance for the public, to our government and defence colleagues as well as the private sector. As an example, if you’ve been on a plane over Europe, Middle East, or Africa; that plane took off because the Met Office (as one of two World Aviation Forecast Centres) provided a forecast. This article explains one of the ways they use AWS to collect these observations, which has freed them to focus more on top quality delivery for their customers.

Benchmarking the NVIDIA Clara Parabricks germline pipeline on AWS

This blog provides an overview of NVIDIA’s Clara Parabricks along with a guide on how to use Parabricks within the AWS Marketplace. It focuses on germline analysis for whole genome and whole exome applications using GPU accelerated bwa-mem and GATK’s HaplotypeCaller.
