In this deck from FOSDEM'19, Thomas Schwinge presents: Speeding up Programs with OpenACC in GCC.
"Proven in production use for decades, GCC (the GNU Compiler Collection) offers C, C++, Fortran, and other compilers for a multitude of target systems. Over the last few years, we -- formerly known as "CodeSourcery", now a group in "Mentor, a Siemens Business" -- added support for the directive-based OpenACC programming model. Requiring only few changes to your existing source code, OpenACC allows for easy parallelization and code offloading to accelerators such as GPUs. We will present a short introduction of GCC and OpenACC, implementation status, examples, and performance results.
OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model."

Addressing Emerging Challenges in Designing HPC Runtimesinside-BigData.com
The document discusses several challenges in designing HPC runtimes for exascale systems, including energy awareness, accelerators, and virtualization. It focuses on the MVAPICH2 project which addresses these challenges. MVAPICH2 provides integrated support for GPUs and MICs, virtualization using SR-IOV and containers, and energy awareness. It also achieves high performance for GPU-aware MPI using features like GPUDirect RDMA. Application tests with HOOMD-blue and COSMO show improvements from MVAPICH2's GPU support.
Check out the latest in OpenACC this month including the PGI 18.1 release, GTC 2018 activity, paper highlights, upcoming events and a call for paper submissions.
This document summarizes a project that aims to improve computational efficiency in solving large sparse linear systems for modeling ablative thermal protection system surfaces by introducing GPU techniques. Three approaches have been attempted so far: 1) using the AMGX library, 2) using new sparse matrix subclasses to perform matrix-vector products on the GPU, and 3) adjusting the CUDA_ITSOL library. The source code uses the PETSc library and takes multiple rounds to converge. Profiling found most time is spent in preconditioning and solving phases, which could benefit from GPU acceleration. The next step is to fully integrate AMGX and test different CPU-GPU ratios. Version control tools like Git are used to manage the code and track changes

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

We will talk about system monitoring from a few different angles. We will start by covering the basics, then discuss SLOs, how to define them, and why understanding the business well is crucial for success in this exercise.
ScyllaDB is making a major architecture shift. We’re moving from vNode replication to tablets – fragments of tables that are distributed independently, enabling dynamic data distribution and extreme elasticity. In this keynote, ScyllaDB co-founder and CTO Avi Kivity explains the reason for this shift, provides a look at the implementation and roadmap, and shares how this shift benefits ScyllaDB users.

Paper: pointerchain: Tracing pointers to their roots –
A case study in molecular dynamics simulations
Millad Ghane, Sunita Chandrasekaran, and Margaret S. Cheung
As scientific frameworks become sophisticated, so do their data structures. A data structure typically
includes pointers and arrays to other structures in order to preserve application’s state. In order to ensure
data consistency from a scientific application on a modern high performance computing (HPC)
architecture, the management of such pointers on the host and the device, has become complicated in
terms of memory allocations because they occupy separate memory spaces. It becomes so severe that
one must go through a chain of pointers to extract the effective address. In this paper, we propose to
reduce the need of excessive data transfer by introducing the idea of pointerchain, a directive that
replaces the pointer chains with their corresponding effective address inside the parallel region of a code.
Based on our analysis, pointerchain leads to a 39% and 38% reduction in the amount of generated
codes and the total executed instructions, respectively.
With pointerchain, we have parallelized CoMD, a Molecular Dynamics (MD) proxy application on
heterogeneous HPC architectures while maintaining a single portable codebase. This portable codebase
utilizes OpenACC, an emerging directive-based programming model, to address the need of memory
allocations from three computational kernels in CoMD. Two of the three embarrassingly parallel kernels
highly benefit from OpenACC and perform better than the hand-written CUDA counterparts. The third
kernel performed 61% of peak performance of its CUDA counterpart. The three kernels are common
modules in any MD simulations. Our findings provides useful insights into parallelizing legacy MD
software across heterogeneous platforms.

Paper: Hardware Acceleration of Reaction-Diffusion
Systems: A Guide to Optimisation of Pattern Formation
Algorithms Using OpenACC
Ruth E. Falconer, Alasdair N. Houston, Xavier Portell, and
Wilfred Otten
Reaction Diffusion Systems (RDS) have widespread applications in computational ecology,
biology, computer graphics and the visual arts. For the former applications a major barrier to
the development of effective simulation models is their computational complexity - it takes a
great deal of processing power to simulate enough replicates such that reliable conclusions
can be drawn. Optimizing the computation is thus highly desirable in order to obtain more
results with less resources. Existing optimizations of RDS tend to be low-level and GPGPU
based. Here we apply the higher-level OpenACC framework to two case studies: a simple
RDS to learn the ‘workings’ of OpenACC and a more realistic and complex example. Our
results show that simple parallelization directives and minimal data transfer can produce a
useful performance improvement. The relative simplicity of porting OpenACC code between
heterogeneous hardware is a key benefit to the scientific computing community in terms of
speed-up and portability.

Paper: OpenACC Parallelization of Stochastic
Simulations on GPUs
Pilsung Kang
We present an OpenACC-based parallelization implementation of stochastic
algorithms for simulating biochemical reaction networks on modern GPUs
(graphics processing units). To investigate the effectiveness of using OpenACC
for leveraging the massive hardware parallelism of the GPU architecture, we
carefully apply OpenACC’s language constructs and mechanisms to
implementing a parallel version of stochastic simulation algorithms on the GPU.
Using our OpenACC implementation in comparison to both the NVidia CUDA
and the CPU-based implementations, we report our initial experiences on
OpenACC’s performance and programming productivity in the context of GPU-
accelerated scientific computing.

The Weather Research and Forecasting (WRF) Model is one of the widely-used
mesoscale numerical weather prediction system and is designed for both atmospheric
research and operational forecasting applications. However, it is an extremely time-
consuming application: running a single simulation takes researchers days to weeks as
the simulation size scales up and computing demands grow. In this paper, we port and
optimize the whole WRF model to the Sunway TaihuLight supercomputer at a large
scale. For the dynamic core in WRF, we present a domain-specific tool, namely,
SWSLL, which is a directive-based compiler tool for the Sunway many-core architecture
to convert the stencil computation into optimized parallel code. We also apply a
decomposition strategy for SWSLL to improve the memory locality and decrease the
number of off-chip memory accesses. For physical parameterizations, we explore the
thread-level parallelization using OpenACC directives via reorganizations of data
layouts and loops to achieve high performance. We present the algorithms and
implementations and demonstrate the optimizations of a real-world complicated
atmospheric modeling on the Sunway TaihuLight supercomputer. Evaluation results
reveal that for the widely used benchmark with a horizontal resolution of 2.5 km, the
speedup of 4.7 can be achieved by using the proposed algorithm and optimization
strategies for the whole WRF model. In terms of strong scalability, our implementation
scales well to hundreds of thousands of heterogeneous cores on Sunway TaihuLight. VIEW NOW
