Direct Style Effect Systems -The Print[A] Example- A Comprehension AidPhilip Schwarz
The subject of this deck is the small Print[A] program in the following blog post by Noel Welsh: https://www.inner-product.com/posts/direct-style-effects/.
Keywords: "direct-style", "context function", "context functions", "algebraic effect", "algebraic effects", "scala", "effect system", "effect systems", "effect", "side effect", "composition", "fp", "functional programming"
Folding Cheat Sheet #4 - fourth in a seriesPhilip Schwarz
For functions that can be defined both as an instance of a right fold and as an instance of a left fold, one may be more efficient than the other.
Let's look at the example of a function 'decimal' that converts a list of digits into the corresponding decimal number.
Erratum: it has been pointed out that it is possible to define the zip function using a right fold (see slide 5).

Visit the following for a description, slideshow, all slides with transcript, pdf, github repo, and eventually a video recording: http://fpilluminated.com/assets/n-queens-combinatorial-puzzle-meets-cats.html
At the centre of this talk is the N-Queens combinatorial puzzle. The reason why this puzzle features in the Scala book and functional programming course by Martin Odersky (the language’s creator), is that such puzzles are a particularly suitable application area of 'for comprehensions'.
We’ll start by (re)acquainting ourselves with the puzzle, and seeing the role played in it by permutations. Next, we’ll see how, when wanting to visualise candidate puzzle solutions, Cats’ monoidal functions fold and foldMap are a great fit for combining images.
While we are all very familiar with the triad providing the bread, butter and jam of functional programming, i.e. map, filter and fold, not everyone knows about the corresponding functions in Cats’ monadic variant of the triad, i.e. mapM, filterM and foldM, which we are going to learn about next.
As is often the case in functional programming, the traverse function makes an appearance, and we shall grab the opportunity to point out the symmetry that exists in the interrelation of flatMap / foldMap / traverse and flatten / fold / sequence.
Armed with an understanding of foldM, we then look at how such a function can be used to implement an iterative algorithm for the N-Queens puzzle.
The talk ends by pointing out that the iterative algorithm is smarter than the recursive one, because it ‘remembers’ where it has already placed previous queens.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
