Trabalho 1 – EPOS
Idle-waiting Thread Joining
– Este trabalho tinha como objetivo alterar o modo que era feito o “join” em uma Thread. Sendo que o mesmo inicialmente era feito da seguinte maneira:
[code lang=”c”] while(_state != FINISHING)
yield();
[/code]
O mesmo consiste basicamente, em verificar o estado da thread que se esta dando join e caso o estado nao seja FINISHING dar a vez a outro processo. Esta solucao, acarreta no consumo excessivo de recursos ja que o mesmo sempre retorna para a fila de _ready. E eh executado novamente quando o escalonador escolher esta thread. O trabalho pede que seja modificado de modo que o consumo de recursos nao seja excessivo.
Arquivos Modificados:
– thread.cc
– Thread.h
Solucao:
Foi criada uma variável adicional em threads.h, _waiting_for_me, que é um ponteiro para uma thread. Quando o método “join” é chamado, a thread que está executando é colocada no _waiting_for_me da thread chamada e é suspensa. Se a thread já finalizou ou alguém já chamou “join” nela, nada é feito. No método “exit”, caso _waiting_for_me esteja preenchida, é chamado o método “resume” na thread referenciada.
Pensamos em colocar uma lista de referências para várias threads poderem dar “join” na mesma thread, porém vimos na documentação do POSIX que isso era considerado um erro lógico, e achamos que acarretaria um consumo de recursos adicional desnecessário, pois não seria possível usar o _link já existente na thread, já que ela teria de estar tanto na lista de suspensos quanto na lista _waiting_for_me da outra thread.
Explicacao mais detalhada da implementacao escolhida e outras solucoes pensadas.
Felt the writer was being honest with the reader which is rare enough that I want to acknowledge it, and a look at growwithclearintent continued that honest feel, content built on actual knowledge rather than aggregated summaries is something I value highly and rarely come across in regular searches on the open internet these days.
Слушайте, какая история — близкий совсем плох, а везти в клинику просто нереально . Я сам через это прошел недавно совсем. Руки опускаются, время тикает. Лезешь в интернет, а вокруг одни обещания . Пока случайно не нашел один реально работающий вариант. Требуется немедленная консультация — а везти самому просто нереально, то нужно вызывать врача на дом. Я про выезд нарколога на дом. В Самаре , если честно, хватает шарлатанов . Нормальные контакты, кто реально приезжает вот тут : нарколога на дом самара нарколога на дом самара Честно скажу , после того как прочитал , понял, как правильно действовать. И про снятие запоя на дому, и про последующее кодирование. Плюс анонимность — это важно . Советую не откладывать.
A piece that earned its conclusions through the body rather than asserting them at the end, and a look at kanzivo maintained the same earned quality, conclusions that follow from what came before are more persuasive than declarations and this site has clearly internalised that principle in how it constructs arguments throughout pieces.
If you asked me to point to a recent positive sign for the open web this site would be near the top, and a stop at growstepbyintent reinforced that designation, the few sites that serve as evidence the web can still produce quality independent content are precious and this one has clearly become one for me.
Thanks for keeping things clear and to the point, that is honestly hard to find online these days, and after reading through clippoise the message stayed consistent which makes me trust the information being shared more than I usually do on similar pages that cover this same kind of topic.
Reading this gave me a small framework I expect to use going forward, and a stop at growwithclearintent extended that framework, content that produces transferable mental models rather than just specific facts is content with multiplicative value and this site is providing those models at a rate that justifies extra attention from me regularly.
Walked away in a slightly better mood than when I started reading, that says something about the writing, and a stop at neatmill kept that going, content that leaves you feeling more capable rather than overwhelmed is the kind I keep coming back to again and again over the years and across many topics.
Liked that there was nothing performative about the writing, and a stop at apricotharborvendorroom continued that genuine quality, performative writing tries to be witnessed rather than read and the difference between performance and substance is huge for the careful reader and this site has clearly chosen substance every time clearly.
Now feeling the small relief of finding writing that does not condescend, and a stop at forgecabins extended that respect for readers, content that treats its audience as capable adults rather than as people to be managed produces a different reading experience and this site has clearly chosen the respectful approach across all pieces.
Really liked the calm tone running through the post, no shouting and no urgency forced into the writing, and a look at crystalharborcommercegallery kept that quiet confidence going, the kind of voice that makes the reader feel respected rather than yelled at which is depressingly common across most modern blog content these days.
A piece that did not try to be timeless and ended up reading as durable anyway, and a look at crystalcovecommerceatelier extended that durable feel, content that stays useful past its publication date without straining for permanence is content that ages well and this site has the kind of evergreen quality that I value highly today.
A thoughtful piece that did not strain to be thoughtful, and a look at larkcliff continued that effortless quality, when thinking shows up in writing without the writer drawing attention to it you know you are reading something genuinely considered rather than something performing the appearance of consideration which is also common online.
Вот такая тема реально бесит , когда близкий просто не может остановиться . Ломаешь голову , а вокруг одна потёмки . Мне вот потребовался срочный метод . Пьют успокоительное , но это ерунда . Нужно именно профессиональная помощь . Я перелопатил кучу сайтов , пока понял одну простую вещь: без круглосуточного наблюдения ничего не выйдет . В обычной квартире срыв стопроцентный . Если ищешь где сделать вывода из запоя в стационаре — обрати внимание на один проверенный вариант . В Нижнем , кстати, тоже полно шарлатанов . Советую перейти на сайт, где реально раскладывают по полочкам про кодировку от алкоголя и выезд врача . Вся суть здесь: наркологическая клиника нижний новгород наркологическая клиника нижний новгород После прочтения , сам офигел , сколько подводных камней в этой теме. Главное — анонимность и палаты. Для Нижнего это реально стоящий вариант.
A relief to read something where I did not have to fact check every claim mentally, and a look at calmcovevendorroom continued that reliable feeling, sites where I can lower my guard and trust the content are rare and this one is earning that trust paragraph by paragraph through consistent careful work behind the scenes.
Now recognising that this site has earned a place in the small group of resources I treat as authoritative, and a stop at kavnero confirmed that placement, the difference between resources I trust and resources I just consume is real and this site has clearly moved into the trusted category through consistent quality over time.
Your method of describing the whole thing in this post is really nice, all
be able to simply understand it, Thanks a lot.
Now appreciating the small but real way this post improved my afternoon, and a stop at directionbeforevelocity extended that small improvement effect, content that produces measurable positive impact on the texture of a reading day is content with real value and this site is producing those small positive impacts at a sustainable rate apparently.
Probably one of the more reliable sources I have found for this kind of careful coverage, and a look at tarotshire reinforced the reliability, the small group of sources I would describe as reliable for a given topic is curated carefully and this site has earned a place in that small group through consistent performance.
Skipped the related links section thinking I had read enough and then came back to it later when curiosity got the better of me, and a stop at kavnero confirmed I should have just read it first, every section of this site appears to deserve careful attention rather than skipping past lazily.
Reading this brought back the satisfaction I used to get from blogs ten years ago, and a stop at northdawn kept that nostalgic quality alive, sites that capture what was good about an earlier era of internet writing are increasingly precious and this one is doing that without feeling like a deliberate throwback at all.
Now thinking the topic is more interesting than I had given it credit for, and a stop at emberbrookmarketfoundry continued that elevated interest, content that revives my curiosity about subjects I had set aside is doing genuine work in the structure of my interests and this site is providing that revivifying effect today actually.
Pass this along to colleagues if the topic comes up, the framing here is sensible, and a stop at findyournextbreakthroughpoint adds more useful angles to share, the kind of content that improves conversations rather than just feeding them is what makes a resource genuinely valuable in professional contexts going forward over time and across project boundaries too.
Let me save you some headache I learned the hard way. Half these local companies promise a custom Porsche and hand you a basic sedan with fake leather. You book a premium ride online, arrive all excited, then boom — hidden service fees everywhere. I’ve been burned like three times already this year alone. If you seriously need a legit vehicle to cruise around the city, don’t just trust the first sponsored ad on social media. Anyone who lives here will tell you the exact same thing, especially since the AC must be arctic and you want zero mileage games.
I literally spent last month comparing maybe twenty different companies, but I eventually found a service with no bait, no switch, and no weird fine print. If you are looking for the only straight shooter for premium rentals across South Florida, check the details here: miami beach luxury car rental miami beach luxury car rental. Also, definitely bring sunglasses unless you enjoy driving completely blind in that sun. Just drive safe out there and maybe skip the extra windshield protection thing. hope this helps some of you save a few bucks.
During a reading session that included several other sources this one stood out, and a look at emberbrookmarketfoundry continued the standout quality, the side by side comparison of sources during research is a useful exercise and this site has been winning those comparisons for me consistently across multiple research sessions during the last week.
Reading this prompted a small redirection in something I was working on, and a stop at findyournextbreakthroughpoint extended that redirecting influence, content that affects my actual work rather than just my thinking has the highest practical impact and this site is providing that level of influence for me at a sustainable rate apparently.
Reading this with a notebook open turned out to be the right move, and a stop at caramelharborvendorparlor added more material to the notes, content that justifies active note taking from a passive reader is content with real informational density and this site is producing notes worthy material at a high rate consistently.
Started smiling at one paragraph because the writing was just nice, and a look at eliteledge produced a couple more such moments, prose that produces small spontaneous reactions in the reader is doing more than just transferring information and the writers here are clearly hitting that level fairly consistently throughout pieces.
Recommended without hesitation if you care about careful coverage of this topic, and a stop at fernharborcommercegallery reinforced the recommendation, the bar I set for unhesitating recommendations is fairly high and this site has cleared it through the cumulative weight of multiple consistently good pieces rather than through any single standout post which is meaningful.
Honestly the simplicity is what makes this work, the topic is not buried under filler words or overly complex examples, and a quick look at createactionableprogress showed the same sensible style, I left with what I came for and no headache from over reading which is a real win these days.
Appreciated how the post felt complete without overstaying its welcome, and a stop at dazzquay confirmed that economical approach runs across the site, knowing when to stop is a skill many writers never develop but here the discipline is obvious and welcome from the perspective of a busy reader trying to learn things efficiently.
Glad to find a site whose links lead somewhere worth going rather than back to itself for SEO juice, and a stop at daisycovecraftcollective kept that generous outbound feel, citing other peoples work with real respect rather than just for ranking signals is a sign of an honest operation worth supporting going forward.
Now noticing that the post benefited from being neither too short nor too long for its content, and a look at findyourforwardpath continued that calibration of length, sites that match length to content rather than padding to hit some target are sites that respect both their material and their readers and this site does both.
Really like that there are no exclamation marks or all caps shouting throughout the post, and a quick visit to figfeat maintained the same calm voice, restraint in punctuation signals confidence in the content and this site clearly trusts its substance to do the persuading rather than relying on typographic emphasis.

Well structured and easy to read, that combination is rarer than people think, and a stop at novalog confirmed the same standard runs across the rest of the site, definitely the kind of place I will be coming back to when this topic comes up in conversation later again over the weeks ahead.
On reflection this is the kind of writing that improves my taste for what is possible in the format, and a look at daisycovecraftcollective continued raising that bar, content that elevates my expectations rather than lowering them is doing important work in calibrating my standards and this site is participating in that elevation reliably.
Знаете, ситуация бывает — человек в ступоре , а везти в больницу просто нереально . Я сам через это прошёл пару лет назад . Сидишь, не знаешь что делать .

Получить профессиональную консультацию – клиника плюс тверь
Started this morning and finished at lunch with a small sense of having spent the time well, and a look at caramelharborcommercegallery extended that satisfaction into the afternoon, content that fits naturally into the rhythm of a working day rather than demanding a dedicated reading block is increasingly the kind I prefer.
Знаете, поиск действительно проверенного медицинского центра — это всегда целая проблема и головная боль. Нередко в жизни бывает так, когда кому-то из членов семьи срочно понадобилась грамотная помощь врачей. И тут сразу возникает главный вопрос: куда именно везти человека?
Мой коллега по работе долго искал по-настоящему работающий и безопасный выход. В интернете сейчас столько мусора и дорвеев, что голова идет кругом. Если коротко, лучше сразу перейти на официальный сайт, где нет вранья, там подробно расписаны все важные условия и нюансы про круглосуточную наркологическую поддержку и условия проживания. В общем, не тяните время и долго не раздумывайте,, чтобы четко во всем разобраться.
Все важные детали и лицензии центра находятся только тут: наркология вывод из запоя в стационаре наркология вывод из запоя в стационаре. Честно говоря, после изучения всех условий, насколько там много подводных камней, на которые стоит обращать внимание, включая комфортные условия содержания, современные палаты и полную анонимность. В Питере это определенно достойный внимания и доверия медицинский центр, который стабильно работает и имеет хорошие отзывы.
The headings made navigating the post simple even when I needed to find a specific section quickly, and a look at maplegrovemarkethall continued the same thoughtful structure, small details like clear headings show that someone is actually thinking about how the reader uses the page rather than just filling it for length alone.
Reading this with a notebook open turned out to be the right move, and a stop at finchfiber added more material to the notes, content that justifies active note taking from a passive reader is content with real informational density and this site is producing notes worthy material at a high rate consistently.
A handful of memorable phrases from this one I will probably use later, and a look at palmmill added a couple more, content that contributes language to my own communication rather than just facts is content with a different kind of utility and this site is providing that linguistic utility consistently across what I read.
Probably the kind of site that should be more widely read than it appears to be, and a look at dewdawn reinforced that quiet wish, the gap between a sites quality and its apparent reach is sometimes large and that gap exists for this site in a way that makes me want to mention it more.
Solid stuff, the kind of post that I will probably refer back to later this month when the topic comes up again, and a look at walnutcovemarkethall only confirmed I should bookmark the site as a whole rather than just this single page for future reference and use across coming weeks.
Probably going to mention this site in a write up I am working on later this month, and a stop at oakarena provided more material for that potential mention, content worth referencing in my own published work rather than just personal reading is content with the highest endorsement level and this site has earned that endorsement.
Reading this on a phone at a coffee shop and finding it perfectly suited to that context, and a stop at elmhilt continued the comfortable mobile experience, content that works across reading conditions without compromising on substance is increasingly important and this site has clearly thought about the whole reader experience here.
Reading this prompted me to subscribe to my first newsletter in months, and a stop at finchfiber confirmed the subscribe was the right call, content that earns a newsletter signup is content that has cleared a higher trust bar than a casual visit and this site has clearly earned that level of commitment from me.
Now feeling the small relief of finding writing that does not condescend, and a stop at palmmill extended that respect for readers, content that treats its audience as capable adults rather than as people to be managed produces a different reading experience and this site has clearly chosen the respectful approach across all pieces.
