ParallelProcessing

ParallelProcessing
A number of Python-related libraries exist for the programming of solutions either employing multiple CPUs or multicore CPUs in a symmetric multiprocessing (SMP) or shared memory environment, or potentially huge numbers of computers in a cluster or grid environment. This page seeks to provide references to the different libraries and solutions available. Just In Time Compilation Some Python libraries allow compiling Python functions at run time, this is called Just In Time (JIT) compilation. Nuitka - As the authors say: Nuitka is a Python compiler written in Python ! Symmetric Multiprocessing Some libraries, often to preserve some similarity with more familiar concurrency models (such as Python's threading API), employ parallel processing techniques which limit their relevance to SMP-based hardware, mostly due to the usage of process creation functions such as the UNIX fork system call. Advantages of such approaches include convenient process creation and the ability to share resources.

Jug: A Task-Based Parallelization Framework — Jug 2.2.1 documentation Short Example¶ Here is a one minute example. Save the following to a file called primes.py: from jug import TaskGenerator @TaskGeneratordef is_prime(n): from time import sleep # Sleep for 1 second, this runs too fast and is not a good demo sleep(1.) for j in range(2, n - 1): if (n % j) == 0: return False return True @TaskGeneratordef count_primes(ps): return sum(ps) @TaskGeneratordef write_output(n): with open('output.txt', 'wt') as output: output.write("Found {0} primes <= 100. Of course, this is only for didactical purposes, normally you would use a better method. Now type jug status primes.py to get: Waiting Ready Finished Running Task name--------------------------------------------------------------------------- 1 0 0 0 primes.count_primes 0 99 0 0 primes.is_prime 1 0 0 0 primes.write_output........................................................................... 2 99 0 0 Total Now you have 32 tasks finished, 4 running, and 63 still ready.

Distributed computing in Python with multiprocessing - Eli Bendersky's website In the previous post, I discussed how the multiprocessing package can be used to run CPU-bound computation tasks in parallel on a multi-core machine. But the utility of multiprocessing doesn't end here. It can also be used to run computations distributed over several machines. This enters the exciting domain of distributed computing. There are many tools available for addressing various aspects of this domain, but here I want to specifically focus on what Python offers right in the standard library, with multiprocessing. The part of the package that makes distributed computing possible is called "managers". The documentation of multiprocessing.managers leaves something to be desired. Managers provide a way to create data which can be shared between different processes. Which is somewhat confusing, since multiprocessing already has synchronization primitives available without using managers (for example Value and Lock). For two main reasons: What this code does is: This manager is simpler.

MATTHEW GOODWIN: The 14 million voters who shared Boris Johnson's vision for a post-Brexit Britain - Dad why has there got to be any change of direction - cant the new leader just carry on It was inevitable Boris Johnson’s resignation would bring out the very worst side of his opponents. From the megalomaniac Dominic Cummings to arch-Remainers, they made little attempt to hide their glee at having finally brought down a Prime Minister they loathe. However, the 14 million people who, less than three years ago, voted Conservative and put Boris Johnson into power, will feel very differently. Unlike the gloating commentariat, many will feel disillusioned, disappointed and demoralised. Because for them, despite his faults, a Johnson-led Government represented a rare chance to push forward a fresh vision of the country – one that’s good for them rather than for the sort of people who dominate the corridors of power. The 14 million certainly wanted to Get Brexit Done and to demolish Jeremy Corbyn’s radical Left. It was inevitable Boris Johnson’s resignation would bring out the very worst side of his opponents They want to Say No to the EU and the courts in Brussels and Strasbourg.

Gps tracking on food to stop theft . yet we went through a depression and no one did that. immigrants again. dm and all media are working on immigrant pr 24/7/365 A major supermarket is tracking £5 rump steaks by satellite to deter thieves as the UK's largest dairy firm warned of shortages of milk and butter with more price rises on the way with a large Lurpak pushing £10. A Co-op in West Bridgford outside Nottingham has put some 'high value' meat items in GPS tracked security cases and blocks of cheese have also been security tagged, a shopper said this weekend. Customers in Bournemouth, Dorset, have reported the same satellite tracking security packs on pork loin joints and other supermarkets have tagged staples such as butter. The retailer said today the security measures are not related to the cost of living and are to do with theft - although experts say the rising cost of food influences shoplifting rates. It came as Arla Foods, the maker of Lurpak and Cravendale milk, said prices will continue to spike because of the rising cost of feed, fuel and fertiliser and continuing problems with recruitment.

NHS green light for eczema pill that can clear skin in a week Three new medications that can fight severe eczema have been given the green light for NHS use. The drugs will be offered to patients who don’t respond to standard treatments or have to quit them due to side effects. Experts say the new treatments – abrocitinib, upadacitinib and tralokinumab – have an almost immediate impact on symptoms. Dr Padma Mohandas, a consultant dermatologist at Barts Health NHS Trust in London, said: ‘Eczema is a common problem but in some cases it’s not easy to treat. Jack Ransom, 27, from South London, had suffered from atopic eczema since he was three months old. Eczema, also called atopic dermatitis, affects more than six million people in the UK ‘With these new drugs we can offer them hope that their skin will get better, which is life-changing.’ Eczema, also called atopic dermatitis, affects more than six million people in the UK. The condition causes areas of skin to become dry, itchy and prone to cracking and bleeding.

Dad: Racism in Africa, black on black racism rampant, they are hypocrites of the first order Overview of racism in Africa Racism in Africa is multi-faceted and dates back several centuries. Congo[edit] Ethiopia[edit] Ivory Coast[edit] In 2001, Ivory Coast saw a resurgence in ethnic hatred and religious intolerance. In 2004, the Young Patriots of Abidjan, a strongly nationalist organisation, rallied by the state media, plundered possessions of foreign nationals in Abidjan. Libya[edit] Liberia[edit] According to Article 27_b of the Liberian Constitution, Liberian nationality is limited to 'persons who are Negroes or of Negro descent'.[8] (see also Liberian nationality law). Mauritania[edit] Slavery in Mauritania persists despite its abolition in 1980 and mostly affects the descendants of black Africans abducted into slavery who now live in Mauritania as "black Moors" or haratin and who partially still serve the "white Moors", or bidhan, as slaves. Namibia[edit] On 12 January 1904, the Herero people, led by Samuel Maharero, rebelled against German colonial rule. Niger[edit] Somalia[edit]

untitled Boris Johnson no-confidence vote: prime minister wins by 211 to 148 but 40% of Tory MPs fail to back him – as it happened - Dad these 40 resigned to force him out, its mob rule Sir Graham Brady, chair of the Conservative 1922 Committee, says 359 votes were cast. There were no spoilt ballots. Confidence in Boris Johnson: 211 No confidence in Johnson: 148 That means more than 40% of Tory MPs voted against Johnson. Here’s a roundup of the key developments from this evening: Boris Johnson was clinging to his premiership on Monday night after 148 of his MPs voted to oust him from Downing Street in a ballot that exposed potentially fatal rifts within his party. My colleague Jessica Elgot has written about how the day of infighting played out. We are closing this liveblog shortly. Our liveblog on the Russia-Ukraine war is still live and you can follow it here: Boris Johnson’s allies had always said about the vote of no confidence that victory by just one vote was still a win, and he would remain in Downing Street and get on with delivering “the people’s priorities”. They will no doubt be cracking opening the bubbly on Monday evening. Read the full story here: Read more here:

Boris Johnson wins no-confidence vote despite unexpectedly large rebellion | Boris Johnson Boris Johnson was clinging to his premiership on Monday night after 148 of his MPs voted to oust him from Downing Street in a ballot that exposed potentially fatal rifts within his party. The prime minister won the support of 211 MPs but 41% of his party voted to get rid of him, with many citing his lack of repentance over the Partygate scandal and the public’s loss of trust in his leadership. It was the worst verdict on a sitting prime minister by their own party in recent times. Although Johnson and his allies claimed the vote as a victory, many Conservative MPs including some of his supporters believe the attempted coup is the beginning of the end for his three-year premiership. With so many of his party having voted against him, the prime minister has effectively lost his majority support in parliament, with the risk that his government is paralysed. The proportion of MPs who voted against Johnson is even greater than the votes against May in 2018 and Margaret Thatcher in 1990.
