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.

Came across this and immediately thought of a friend who would enjoy it, and a stop at uniquevalueoutlet also reminded me of someone, content that triggers the urge to share is content that has earned my recommendation and this site has earned multiple from me already across different conversations during the week.

Strong recommendation, anyone interested in this topic owes themselves a visit, and a stop at fashionloversstore extends that recommendation across more of the site, this is the kind of resource that makes me more optimistic about the state of the open web than I usually am these days actually for once which is genuinely refreshing.

Now recognising the editorial wisdom of letting some questions remain open at the end, and a look at learnwithoutlimits continued that intellectual honesty, content that does not force closure on contested questions is content that respects the limits of knowledge and this site has clearly developed the maturity to know when to leave space.
Reading this prompted me to subscribe to my first newsletter in months, and a stop at freshvaluestore 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.
Worth marking the moment when reading this clicked into something useful for my own work, and a look at findgreatoffers extended that practical click, content that connects to my actual life rather than just being interesting is content with the highest kind of value and this site is generating that connection at a high rate.
Makes sense to me.
I appreciate the clarity here, everything is explained in simple terms without unnecessary detail, and after a quick stop at findgreatoffers the points came together nicely for me, the writing keeps things straightforward and respects the reader from start to finish without ever talking down to anyone.
Reading this in three sittings because the day was fragmented, and the piece survived the fragmentation, and a stop at shopandsmilemore held up under similar reading conditions, content engineered for continuous attention is fragile in modern conditions and this site reads as durable across the realistic ways people consume content today.

A piece that demonstrated competence without performing it, and a look at boldswap maintained the same self assured but unshowy register, the gap between competence and performance of competence is one I track and this site has clearly chosen to demonstrate rather than perform which I find much more persuasive as a reader.
Took me back a step or two on an assumption I had been making, and a stop at trendylivinghub pushed that reconsideration further, writing that gently corrects the reader without being aggressive about it is a rare diplomatic skill and the team here clearly knows how to land critical points without turning readers off.
Worth saying that the writing carries a particular kind of authority without making any explicit claims to it, and a stop at fullbloomdesigns extended that earned authority feeling, sites that demonstrate expertise through the quality of their explanations rather than by stating credentials are sites I trust most and this site has it.
Thanks for not padding this with the usual filler intros and outros that every other blog seems to require, and a quick visit to discoverfashioncorner continued that lean approach across more posts, content stripped of waste is content that respects you and I will always come back to that kind of approach.
Worth recognising that the post handled a familiar topic without reaching for any of the obvious hot takes, and a stop at brightvaluehub continued that fresh treatment, sites that find new angles on subjects others have exhausted are sites worth following carefully and this one has clearly developed that exploratory instinct through patient practice.
Reading this prompted a small redirection in something I was working on, and a stop at brightstyleoutlet 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.
Worth flagging this post as worth a careful read rather than a casual skim, and a stop at fashiondailyhub earned the same careful approach, the few sites that warrant slower reading are sites I now treat differently from the daily content stream and this one has clearly moved into that elevated treatment category.
Picked up something useful for a side project, and a look at naturerailstore added another piece I will incorporate, content that connects to specific projects I am working on is content with practical utility and the practical utility of this site is showing up across multiple posts I have read in the last hour or so.
Felt energised after reading rather than drained, which is unusual for online content these days, and a look at softstoneemporium continued that good feeling, content that leaves you better than it found you is rare and worth bookmarking when you stumble across it for the first time today or any other day really.
Started reading and ended an hour later without realising the time had passed, and a look at startfreshnow produced the same time dilation effect, when content makes time feel different the writer has achieved something well beyond the average and this site is producing that experience for me reliably across multiple readings.
Reading this with a notebook open turned out to be the right move, and a stop at freshchoicehub 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.
My friends would appreciate a few of these posts and I will be sending links accordingly, and a look at bestbuycorner added more pages to my share queue, content that earns shares to specific people in specific contexts is content with social utility and this site is generating those targeted shares from me consistently lately.
Honestly thank you to whoever wrote this because it scratched an itch I had not quite been able to articulate, and a stop at boltdepot kept that satisfying feeling going, the kind of writing that meets unspoken needs is special and this site clearly has writers who understand their readers more than most do today.
The structure of the post made it easy to follow without losing track of where I was, and a look at freshtrendcorner kept the same logical flow going, this site clearly understands that organisation is half the battle in keeping readers engaged from the first line to the last across any kind of post.
A piece that read as the work of someone who reads carefully themselves, and a look at midcitycollections continued that informed feel, writers who are also serious readers produce work with a different quality and this site reads as the product of someone steeped in good writing rather than just generating content for an audience.
Now noticing the careful balance the post struck between confidence and humility, and a stop at shopandsmiletoday maintained the same balance, finding the line between asserting and admitting is hard and this site has clearly developed the calibration to walk that line consistently which produces a more persuasive reading experience for me.
Now feeling confident that this site will continue producing work I will want to read, and a look at trendloversplace extended that confidence into the future, projecting forward from current quality to expected future quality is something I do for sites I genuinely follow and this one has earned that forward looking trust clearly today.
The whole experience of reading this was pleasant from start to finish, no pop ups and no annoying interruptions, and a look at namedriftboutique continued that clean experience, technical choices about page design matter for the reader and this site clearly cares about the small details that add up to comfort across multiple visits.
Honestly this hits the sweet spot between detail and brevity, no rambling and no shortcuts, and a quick visit to shopandsmiletoday kept that going across the related pages, the kind of place that respects your attention without trying to grab it through cheap tactics or attention seeking design choices that get tired fast.
Just sat back at the end of the post and felt grateful that someone took the time to write it, and a look at simplegiftfinder extended that gratitude across more of the site, recognising effort behind quality work is part of what makes the open web a community rather than just a marketplace today.
Bookmark earned and folder updated to track this site separately, and a look at besttrendshub confirmed the folder upgrade was the right call, organising my reading list so that good sites do not get lost in a sea of casual bookmarks is something I do more carefully now and this site warranted its own spot.
Came in skeptical of the angle and left mostly persuaded, and a stop at forestlanecreations pushed me a bit further in the same direction, content that can move a critical reader by argument rather than rhetoric is rare and worth pointing out because it indicates real substance underneath the surface presentation here.
Appreciate that you did not pad this with fluff to hit a word count, the post says what it needs to say and stops, and a look at modernfashionhub did the same, brevity here feels intentional not lazy which is a distinction many writers miss completely sometimes when they are working under deadlines.
Probably the kind of site that should be more widely read than it appears to be, and a look at mountainviewoutlet 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.
Really grateful for content like this, it does not waste my time and it does not insult my intelligence either, and a quick look at trendfashioncorner was the same, balanced respectful writing that makes a person feel welcome rather than rushed through pages of forced engagement just to keep clicking around.
The tone stayed consistent across the whole post which is harder than it looks for longer pieces, and a look at bestbuycollection continued the same voice, this kind of editorial consistency is a sign of either a single careful writer or a tightly run team and either is impressive today across the broader media environment.
Thank you for the genuine effort here, it shows in every paragraph and not just the headline, and after my visit to learnsomethingvaluable I was sure this site cares about getting things right rather than chasing clicks, which is the main reason I will come back later this week to read more.
Now feeling the rare pleasure of trusting a source completely on first encounter, and a look at uniquegiftplace extended that initial trust into something more durable, the calibration of trust to evidence is something I do informally and this site has earned high trust through the cumulative weight of multiple consistently good posts already.
Worth flagging that this approach to the topic is fresh without being contrarian, and a stop at mountainviewoutlet extended the same fresh angle, finding original perspective on familiar subjects is rare and this site has clearly developed its own way of seeing rather than echoing the dominant takes from elsewhere consistently.
Liked everything about the experience, from the opening through to the closing notes, and a stop at trendfashioncorner extended that into more pages, finding a site where the editorial vision shows through every choice rather than feeling random is an increasingly rare experience and one I am glad to have today during this particular reading session.
Now noticing how rare it is to find a site that does not feel rushed, and a look at smartbuyplace extended that calm pace, content produced without time pressure has a different quality than content shipped to meet a deadline and this site reads as written without urgency which produces a different and better experience for readers.
Strong recommendation, anyone interested in this topic owes themselves a visit, and a stop at uniquegiftplace extends that recommendation across more of the site, this is the kind of resource that makes me more optimistic about the state of the open web than I usually am these days actually for once which is genuinely refreshing.
Reading carefully here has reminded me what reading carefully feels like, and a look at happytrendworld extended that reminder, the experience of careful reading versus skimming is different in ways I had partially forgotten and this site has clearly refreshed my memory of what attention feels like when content rewards it consistently.
Reading this in pieces over a coffee break and finding it consistently rewarding, and a stop at discovernewvalue extended that into related material I will return to later, the kind of site that fits naturally into small reading windows without requiring a long uninterrupted block is genuinely useful for how I actually browse.
Halfway through reading I knew this would be one to bookmark, and a look at trendmarketplace confirmed that early intuition, when bookmark intent forms before finishing a post you know the writing has cleared a quality bar that most content fails to clear and this site has cleared it on multiple visits already.
Glad the writer kept this short rather than padding it out, the points stand on their own without needing extra context, and a look at timelessharbornow kept the same approach going, brevity is a sign of confidence in the substance and the team here clearly trusts their content to land without filler.
If you scroll past this site without looking carefully you will miss something, and a stop at brightchoicecollection extended that mild warning, the surface of the site does not advertise its quality loudly which means careful attention is required to recognise what is being offered here which is itself a kind of editorial signal.
