 ## P3HPC'20: International Workshop on Performance, Portability, and Productivity in HPC
-Performance Portability is a key reasearch area for the group, and at this year's [P3HPC workshop](http://p3hpc.org) we have two publications.
+Performance Portability is a key research area for the group, and at this year's [P3HPC workshop](http://p3hpc.org) we have two publications.
 
 Tom Deakin, Andrei Poenaru, Tom Lin and Simon McIntosh-Smith have expanded the [2019 survey](https://doi.org/10.1109/P3HPC49587.2019.00006) of performance portability to include the latest and greatest processors (Fujitsu A64FX, NVIDIA A100 Ampere GPUs, Amazon Graviton 2, etc) and programming models such as SYCL.
 The paper, *Tracking Performance Portability on the Yellow Brick Road to Exascale*, shows very promising performance portability for open-standard programming models such as OpenMP. We also build on our [2019 study](https://doi.org/10.1109/P3HPC49587.2019.00006) and track some historical trends.

 ## MCHPC'20: Workshop on Memory Centric High Performance Computing
 
-Batched linear algebra is an important piece of the HPC arsenal. For finite element codes, batches of very small linear systems, are created and solve on the fly. Tom Deakin will present work co-authored with James Cownie, Simon McIntosh-Smith, Justin Lovegrove and Richard Smedley-Stevenson on how the way memory is allocated can cause big performance differences. In the paper, [Hostile Cache Implications for Small, Dense Linear Solves](https://sc20.supercomputing.org/presentation/?id=ws_mchpc102&sess=sess195) which we'll present in the [MCHPC'20 workshop](https://passlab.github.io/mchpc/mchpc2020/), we observe false-sharing cache behaviour, something which is crucial to mitigate for good performance.

 ## PyHPC 2020: 9th Workshop on Python for High-Performance and Scientific Computing
 
-PhD Student, and Research Engineer at HPE, Clément Foyer will be sharing their work along with Simon McIntosh-Smith and co-authors from BSC and NAG on *Enabling System Wide Shared Memory for Performance Improvement in PyCOMPSs Applications* at the [PYHPC 2020](https://pyhpc.io) workshop. Shared memory support was added to parallel Python programs in PyCOMPSs and they show performance improvements of using this approach.

 Simon McIntosh-Smith and Tom Deakin are running their popular *Programming your GPU with OpenMP: A Hands-on Introduction* tutorial will be split over two days ([Part 1](https://sc20.supercomputing.org/presentation/?id=tut155&sess=sess237) and [Part 2](https://sc20.supercomputing.org/presentation/?id=pec101&sess=sess240)). There are plenty of hands-on exercises planned between pre-recoded presentations, so attendees can gain practical experience writing OpenMP code targeting GPUs in the [Isambard supercomputer](https://gw4.ac.uk/isambard/).
