It is therefore essential to ensure that the modifications in the source code aroused by bug fixing or new feature development wouldn’t compromise the accuracy and functionality that has already been validated and verified. With this in mind, this paper introduces a method for developing and implementing an automatic regression test environment and takes the open-source multiphysics library SPHinXsys [1] as an example. Firstly, the reference database for each benchmark test is generated from monitored data by multiple executions. This database contains the maximum variation range of metrics for different types of strategies, i.e., time-averaged method, ensemble-averaged method as well as the dynamic time warping method, covering the uncertainty arising from parallel computing, particle relaxation, physical instabilities, etc. Then, new results obtained after source code modification will be tested with them according to a curve-similarity-based comparison. Whenever the source code is updated, the regression test will be carried out automatically for all test cases and used to report the validity of the current results. This regression test environment has already been implemented in all dynamics test cases released in SPHinXsys, including fluid dynamics, solid mechanics, fluid-structure interaction, thermal and mass diffusion, reaction-diffusion, and their multi-physics coupling, and shows good capability for testing various problems. It’s worth noting that while the present test environment is built and implemented for a specific scientific computing library, its underlying principle is generic and can be applied to many others. Keywords: Scientific computing, Open-source library, Verification and validation, Regression test, Automatic test environment, Curve similarity comparison, Smoothed particle hydrodynamics.

Following the definition of validation and verification of scientific computing claimed by William [4], scientific computing should always represent the real world and the conceptual model accurately. However, this is a challenging task due to the complex mathematical models and calculations, which often require changes to separate parts of the application and definitely increase the possibility of errors. Moreover, the development of scientific applications is a lasting work, and changes occur frequently due to different requirements and new features introduced. The applications should always produce trustworthy results and assure the application qualities with the help of validation and verification conducted alongside both application development and usage [5]. Implementing testing, including unit test, integration test, regression test, system test, etc., can provide concrete validation and verification procedures. Notwithstanding the fact that it has already been adopted in many IT software, scientific applications, especially some open-source libraries, find it difficult to perform those testing directly with traditional techniques. One main challenge is due to the characteristics of the scientific application, as it’s hard to find a test oracle to check if the program can gain the expected output when executing test cases [6, 7]. Another challenge arises from cultural differences between scientists and the software engineering community [6]. Many scientific applications are usually developed by small-group scientists, who may not be very familiar with accepted software engineering practices, and haven’t studied the developing process of their software in much detail [8], and therefore may overlook the impact of changes. Regression test stands a great chance to ensure the output validity of scientific applications under development. It is a re-testing activity, which refers to executing the test suite with given inputs and comparing the output with previously stored reference results when modifications occur or new features are added. In this way, developers can make sure that their changes don’t cause any unexpected side effects and previous functionalities are still verified [7]. Since taking the regression test for all test cases is generally Conclusion This paper introduces a method for developing an automatic regression test environment for open-source scientific libraries and uses SPHinXsys as an illustration to demonstrate its functionality. For scientific libraries under centralized development, it’s essential to guarantee the accuracy of simulation results all the time, and the regression test provides this procedure. The reference database for each benchmark test is generated using different strategies, and the new result after code modifications can be automatically tested with them once the source code is updated. This regression test environment has been implemented in all test cases released in SPHinXsys, and it shows great functionality to check the validity of the new result obtained after code modifications. By doing such work, we also want to draw some attention from general scientific computing communities to emphasize the software performance during development. The principle of the regression test proposed here is universal and can be applied and extended in other libraries and applications. In the future, other regression test methods will be implemented, and with the number of test cases swelling due to adding new dynamics features, selection and reduction of test cases will also be adopted.

Unlock us Abstract Extending Moore’s law by augmenting complementary-metal-oxide semiconductor (CMOS) transistors with emerging nanotechnologies (X) has become increasingly important. Accelerating Monte Carlo algorithms that rely on random sampling with such CMOS+X technologies could have signi€cant impact on a large number of €elds from probabilistic machine learning, optimization to quantum simulation. In this paper, we show the combination of stochastic magnetic tunnel junction (sMTJ)-based probabilistic bits (p-bits) with versatile Field Programmable Gate Arrays (FPGA) to design a CMOS + X (X = sMTJ) prototype. Our approach enables high-quality true randomness that is essential for Monte Carlo based probabilistic sampling and learning. Our heterogeneous computer successfully performs probabilistic inference and asynchronous Boltzmann learning, despite device-to-device variations in sMTJs. A comprehensive comparison using a CMOS predictive process design kit (PDK) reveals that compact sMTJ-based p-bits replace 10,000 transistors while dissipating two orders of magnitude of less energy (2 fJ per random bit), compared to digital CMOS p-bits. Scaled and integrated versions of our CMOS + stochastic nanomagnet approach can signi€cantly advance probabilistic computing and its applications in various domains by providing massively parallel and truly random numbers with extremely high throughput and energy-eciency. https://www.wikipt.org/csx/creations/cmos-%2B-stochastic-nanomagnets%3A-heterogeneous-computers-for-probabilistic-inference-and-learning Quick View Newly listed Tphysletters A Unifying Bag Model of Composite Fermionic Structures in a Cold Genesis Theory Regular Price $700.00 Sale Price $400.00 Excluding Sales Tax Quick View TphysicsLetters Detection of the large-scale tidal field with galaxy multiplet alignment in the Regular Price $1,900.00 Sale Price $950.00 Excluding Sales Tax Quick View Newly listed Tphysletters Violation of γ in Brans-Dicke gravity Regular Price $1,000.00 Sale Price $600.00 Excluding Sales Tax Quick View Astrophysics Observations and detectability of young Suns’ flaring and CME activity in optica Regular Price $1,000.00 Sale Price $450.00 Excluding Sales Tax Quick View TphysicsLetters Tunable structure-activity correlations of molybdenum dichalcogenides (MoX2; X=S Regular Price $2,000.00 Sale Price $400.00 Excluding Sales Tax Quick View New Thphysletters Bayesian and frequentist investigation of prior effects in EFTofLSS analyses of Regular Price $3,000.00 Sale Price $370.00 Excluding Sales Tax Quick View New Thphysletters A search for faint resolved galaxies beyond the Milky Way in DES Year 6: A new f Regular Price $1,900.00 Sale Price $750.00 Excluding Sales Tax Quick View New X-ray polarization properties of partially ionized equatorial obscurers around a Regular Price $800.00 Sale Price $350.00 Excluding Sales Tax Quick View New Unravelling multi-temperature dust populations in the dwarf galaxy Holmberg II Regular Price $1,200.00 Sale Price $400.00 Excluding Sales Tax Quick View New SpookyNet: Advancement in Quantum System Analysis through Convolutional Neural N Regular Price $1,500.00 Sale Price $500.00 Excluding Sales Tax Quick View New Rapid neutron star cooling triggered by accumulated dark matter Regular Price $1,500.00 Sale Price $500.00 Excluding Sales Tax Quick View Newly listed Tphysletters Searching for Radio Outflows from M31* with VLBI Observations Price $300.00 Excluding Sales Tax Load More Introduction With the slowing down of Moore’s Law [1], there has been a growing interest in domain-specific hardware and architectures to address emerging computational challenges and energy-efficiency, particularly borne out of machine learning and AI applications. One promising approach is the co-integration of traditional complementary metaloxide semiconductor (CMOS) technology with emerging nanotechnologies (X), resulting in CMOS + X architectures. the primary objective of this approach is to augment existing CMOS technology with novel functionalities, enabling the development of energy-ecient hardware systems that can be applied to a wide range of problems across various domains. By blending CMOS with alternative materials and devices, CMOS + X architectures can enhance traditional CMOS technologies in terms of energy-efficiency and performance Being named one of the top 10 algorithms of the 20th century [2], Monte Carlo methods have been one of the most ∗ ‘ese authors contributed equally effective approaches in computing to solve computationally hard problems in a wide range of applications, from probabilistic machine learning, optimization to quantum simulation. Probabilistic computing with p-bits [3] has emerged as a powerful platform for executing these Monte Carlo algorithms in massively parallel [4, 5] and energy efficient architectures. p-bits have been shown to be applicable to a large domain of computational problems from combinatorial optimization to probabilistic machine learning and quantum simulation [6–8]. Several p-bit implementations that use the inherent stochasticity in different materials and devices have been proposed, based on di‚usive memristors [9], resistive RAM [10], perovskite nickelates [11], ferroelectric transistors [12], single photon avalanche diodes [13], optical parametric oscillators [14] and others. Among alternatives sMTJs built out of low-barrier nanomagnets have demonstrated signi€cant potential due to their ability to amplify noise, converting millivolts of ƒuctuations to hundreds of millivolts over resistive networks [15], unlike alternative approaches with amplifiers [16]. Another advantage of sMTJ-based pbits is the continuous generation of truly random bitstreams without the need to be reset in synchronous pulsebased designs [17, 18]. The possibility of designing energy-efficient p-bits using low-barrier nanomagnets has ...............Read more by purchasing the full lenghth. Conclusion This work demonstrates the first hardware demonstration of a heterogeneous computer combining versatile FPGAs with stochastic MTJs for probabilistic machine learning and inference. We introduce a new variation tolerant pbit circuit that is used to create an asynchronous clock domain, driving digital p-bits in the FPGA. In the process, the CMOS + sMTJ computer shows how commonly used and inexpensive PRNGs can be augmented by magnetic nanodevices to perform as well as high quality PRNGs, both in probabilistic inference and learning experiments. Our CMOS + sMTJ computer also shows the first demonstration of training a deep Boltzmann network in a 32-node Chimera topology, leveraging the asynchronous dynamics of sMTJs. Careful comparisons with existing digital circuits show the true potential of integrated sMTJs which can be scaled up to million p-bit densities far beyond the capabilities of present day CMOS technology.

We demonstrate its capabilities through a variety of gratings using different wavelengths and waveguide materials, designed for new ion traps with all optics fully integrated, including UV and visible wavelengths.

While QDs emitting in the 780nm to 950nm spectral range feature closeto-ideal single-photon purities and indistinguishabilities, they are not the best choice for applications in fiber-optical networks, due to the high optical losses in this wavelength regime. The preferable choice here are QDs operating in the lowest-loss spectral window around 1550 nm (telecom C-band). Read More June 13, 2023 at 6:30:00 AM Exceptional Classifications of Non-Hermitian Systems Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed that adiabatic encircling of exceptional points (EPs) leads to a nontrivial Berry phase in addition to an exchange of eigenstates. Based on these phenomena, we propose in this work an exhaustive classification framework for EPs in non-Hermitian physical systems. In contrast to previous classifications that only incorporate the eigenstate exchange effect, our proposed classification gives rise to finer Z2 classifications depending on the presence of a π Berry phase after the encircling of the EPs.

Specifically, we calculate the one-loop corrections to the propagators and vertex functions of the model and determine the one-loop beta function of the non-minimal electromagnetic coupling. Additionally, we perform calculations of the two-loop corrections to the gauge field propagator, demonstrating that it remains massless and transverse up to this order. We also find that the non-minimal electromagnetic coupling can exhibit asymptotic freedom if a certain condition is satisfied. As a potential dark matter candidate, these findings suggest that the field may decouple at high energies.

This is achieved by solving a highly nonnlinear and nonunique inverse problem. Bayesian inference is therefore used to quantify uncertainties in the solution. Variational inference is a method that provides probabilistic, Bayesian solutions efficiently using optimization.

Read More June 8, 2022 at 8:30:00 PM Physics-inspired Ising Computing with Ring Oscillator Activated p-bits The nearing end of Moore’s Law has been driving the development of domain-specific hardware tailored to solve a special set of problems. Along these lines, probabilistic computing with inherently stochastic building blocks (p-bits) have shown significant promise, particularly in the context of hard optimization and statistical sampling problems. p-bits have been proposed and demonstrated in different hardware substrates ranging from small-scale stochastic magnetic tunnel junctions (sMTJs) in asynchronous architectures to large-scale CMOS in synchronous architectures. Here, we design and implement a truly asynchronous and medium-scale p-computer (with  800 pbits) that closely emulates the asynchronous dynamics of sMTJs in Field Programmable Gate Arrays (FPGAs).

We have performed systematic first-principles calculations of the behaviour of ruthenium nanoclusters on a graphene monolayer and intercalated them into a bilayer. Our computational results show that at a scientifically high density of single Ru atom interstitials, intercalated atoms can shear the surrounding lattice to an AA stacking confi guration, an effect which weakens with increasing cluster size. Moreover, the interlayer stacking con figuration, in turn, has a signi ficant effect on cluster diffusion.

Due to the limited size and capabilities of one single nanomachine, a large number of nanomachines that cooperate to form a nanonetwork are attractive for completing complex tasks [2].

However, the structure and electronic properties of its edge are often neglected, although they are important for nanoscale devices because the edge ratio becomes larger by decreasing the device size. In this study, we suggest a way to fabricate graphene with atomically aligned zigzag edges by applying the hydrogen-plasma etching (HPE) technique.

Our study reveals long-range interactions between the impurities, which decay according to a power law, mediated by the supercurrents. Importantly, these interactions possess a ferromagnetic component when considering the influence of the electromagnetic field, leading to the parallel alignment of the magnetic moments in the case of two impurities.
