MPI in TNT for parallel processing
•
0 likes•458 views
TNT (a widely used program for phylogenetic analysis) already has PVM (Parallel Virtual Machine) for parallel jobs handling. However: - MPI remains the dominant model used in high-performance computing today. It has become a de facto standard for communication among processes that model a parallel program. - Actual supercomputers such as computer Clusters often run such programs. The project goal was to integrate MPI onto TNT and next to PVM. The user decides one or the other. Syntax and commands are practically the same.

Concurrent Programming OpenMP @ Distributed System Discussion
This powerpoint presentation discusses OpenMP, a programming interface that allows for parallel programming on shared memory architectures. It covers the basic architecture of OpenMP, its core elements like directives and runtime routines, advantages like portability, and disadvantages like potential synchronization bugs. Examples are provided of using OpenMP directives to parallelize a simple "Hello World" program across multiple threads. Fine-grained and coarse-grained parallelism are also defined.
OpenMP And C++
C++ and OpenMP can be used together to create fast and maintainable parallel programs. However, there are some challenges to parallelizing C++ code using OpenMP due to inconsistencies between the C++ and OpenMP specifications. Objects used in OpenMP clauses like shared, private, and firstprivate require special handling of constructors, destructors, and assignment operators. Parallelizing C++ loops can also be problematic if the loop index is not an integer type or if the loop uses STL iterators. STL containers introduce additional issues for parallelization related to initialization and data distribution across processors.

It provides an overview of OpenMP, including that it is an industry standard for parallel programming in C/C++ that supports parallelizing loops and tasks. Examples are given of using OpenMP to parallelize particle system position calculation and collision detection across multiple threads. Performance tests on dual-core and triple-core systems show speedups of 2-5x from using OpenMP. Some limitations of OpenMP are also outlined.
Parallelization using open mp
The document provides an overview of parallelization using OpenMP. It discusses how parallel programming models have evolved with hardware to improve performance and efficiency. It describes shared memory and message passing models like OpenMP and MPI. The document compares OpenMP and MPI, detailing their pros and cons. It explains how OpenMP can be used to achieve parallelism on shared memory systems using compiler directives and libraries.
Open mp library functions and environment variables
The document discusses OpenMP library functions and environment variables. It provides examples of some of the most heavily used OpenMP library functions like omp_get_num_threads(), omp_set_num_threads(), and omp_get_thread_num(). It also lists some additional OpenMP library functions for initializing, destroying, setting, and testing simple locks. An example code shows how these functions can be used within an OpenMP parallel region to distribute a loop workload across threads. Finally, it discusses some common OpenMP environment variables for setting the schedule, number of threads, and enabling dynamic thread adjustment.
Parllelizaion
OpenMP is an API that supports shared memory multiprocessing in C, C++ and Fortran. It uses compiler directives, runtime library routines and environment variables to define parallel regions of code that can be executed simultaneously by multiple threads. The master thread creates a team of parallel threads to execute code blocks marked with OpenMP pragmas. When the parallel region is complete, the threads synchronize and terminate, leaving the master thread to continue execution. Common OpenMP constructs include parallel, work-sharing like for loops, and synchronization methods like barriers.

My ppt hpc u4
Message Passing Interface (MPI) is a language-independent communications protocol used to program parallel computers. Both point-to-point and collective communication are supported.
MPI "is a message-passing application programmer interface, together with protocol and semantic specifications for how its features must behave in any implementation." So, MPI is a specification, not an implementation.
MPI's goals are high performance, scalability, and portability.
OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared memory multiprocessing programming in C, C++, and Fortran, on most platforms, processor architectures and operating systems, including Solaris, AIX, HP-UX, Linux, MacOS, and Windows.
OpenMP uses a portable, scalable model that gives programmers a simple and flexible interface for developing parallel applications for platforms ranging from the standard desktop computer to the supercomputer.
Tutorial on Parallel Computing and Message Passing Model - C2

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

MPI in TNT for parallel processing
- 1. The Message Passing Interface (MPI) in TNT Martín Morales Pablo Goloboff UEL (CONICET – FML) 1/5
- 2. Parallel computing. Parallel computers. Parallel computing: simultaneous execution of computational processes that allow the division of a work or problem. Parallel computers: special hardware systems to perform parallel computing. • Clusters: group of individual computers connected by a local area network (LAN). Most common: Beowulf. • Multi-core computers: computer with a processor with two or more processing units. Most computers today are multi-core. That's means that we can run parallel apps (as TNT!) in a real parallel hardware without a Cluster; just with our single computer! MPI. The standard. The implementation. MPI: Message Passing Interface. Standard. It defines a communication protocol for parallel computing execution. An MPI implementation is the software that applies (implement) the standard. There are many implementations made of MPI. We choosed Open MPI. Why TNT-MPI? TNT already has PVM (Parallel Virtual Machine) for parallel jobs handling. However: • MPI remains the dominant model used in high-performance computing today. It has become a de facto standard for communication among processes that model a parallel program. • Actual supercomputers such as computer Clusters often run such programs. • Many sysadmins do not allow PVM to be run on their Clusters because if the way in which PVM uses resources (Pablo dixit.) TNT-MPI The project goal was to integrate MPI onto TNT and next to PVM. The user decides one or the other. Syntax and commands are practically the same. Hosts in MPI (Clusters) 2/5 Hosts in MPI are loaded from a simple text file usually called hostfile. Column 1: host name. Column 2: slots: how many processes can potentially run in this host? Column 3: max_slots: are we going to limit slots use in this host? master: usually, computer that starts processes (a job) on workers hosts and coordinates all of their work. worker: usually, computer that executes part of that job. Oversubscription: when the number of processes in the host is greater than cores or processors in it.
- 3. Install will be... MPI implementation binaries must be in all nodes (if Cluster) and pointed to them in env variables. Then it must define hostfile (if Cluster). Recommended implementation (at the moment): Open MPI version 4.0.1. Release date: March 2019. TNT-MPI Stage PARALLEL COMMANDS PVM MPI again, begin, cleansig, close, get, gwait, kill, mnemonic, pause, reset, resume, setram, setdata, spy, status, stop, timeout, wait IMPLEMENTED goto, host commands, load, skipto, tagset soon... Scripts As PVM, MPI scripts runs directly in TNT built-in script interpreter. But, if we want to use MPI with the new C interpreter we can do it “indirectly” with tnt() function (example below). Of course, we can do this with PVM too. Next • Full testing and probably... bug fixes. • Windows. This development is at the moment just Linux and OS X (Mac) compatible. 3/5 • Development is in a final stage. About 90%. • Main functionalities are already done. • We can run jobs and get results; run swaps, scripts...
