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.
Skipped to a specific section because I knew that was the question I had, and the answer was clean, and a stop at flagsync similarly delivered targeted answers without burying them, content engineered for readers who arrive with specific needs rather than open ended browsing is increasingly valuable in a search heavy reading environment.

Appreciated that the writer trusted the reader to follow along without constant restating of earlier points, and a look at creativefashioncorner continued that respect for the reader, treating an audience as capable adults rather than as people to be hand held through every paragraph is something I notice and value highly across the open internet today.

Good quality through and through, no rough edges and no signs of being rushed, and a quick look at simplegiftfinder kept the same polish going, the kind of site that respects its own brand by maintaining consistency across pages which is something I always appreciate as a reader looking for trustworthy information online today.
Once you start reading carefully here it is hard to go back to lower quality alternatives, and a stop at yourdailyvalue reinforced that ratchet effect, the way good content raises standards is real over time and this site has clearly contributed to raising my expectations for what is possible in writing on the topic generally.
Took a few notes from this post, the points are easy to remember without needing to come back and check, and a look at olivepick added a couple more, the kind of place that sticks in the memory long after the browser tab has been closed for the day which says a lot really.
Thanks for the clean writing, no broken sentences and no awkward translations like some other sites have, and a quick stop at sprygain kept that polish going nicely, it really does make a difference when a reader can move through a page without tripping on every line or going back to reread.

Comfortable reading experience throughout, no jarring tone shifts and no awkward formatting, and a look at trustedshoppinghub kept that smooth feel going, the kind of editorial polish that goes unnoticed when present but glaring when absent is something this site has clearly invested in across the broader content as well which deserves recognition.
Quietly building a case in my head for why this site deserves more attention than it currently seems to receive, and a look at sprygain reinforced the case, the gap between quality and recognition is a recurring frustration in independent online content and this site is one of the cases that seems particularly egregious to me today.
Came in expecting another generic take and got something with actual character instead, and a look at createimpactnow carried that personality forward, finding a distinct voice on a saturated topic is impressive and worth pointing out when it happens because most sites end up sounding identical to their nearest competitors quickly.

Glad I clicked through from where I did because this turned out to be worth the time spent, and after cloudpetalstore I had a fuller picture, the kind of content that earns its visitors through delivering value rather than chasing them through aggressive advertising or constant pop ups appearing everywhere on the screen lately.
Bookmark added with a small note about why, and a look at flagtag prompted another bookmark with another note, the bookmarks I annotate are the ones I expect to return to deliberately rather than stumble into and this site is generating annotated bookmarks at a higher rate than my usual content sources by some margin.
Liked the way the post balanced confidence and humility, and a stop at modernvaluecollection maintained the same balance, knowing when to assert and when to acknowledge uncertainty is a sign of mature thinking and the writers here have clearly developed that calibration through what I assume is years of careful work on their craft.
Great work on keeping things readable, the post never drags or repeats itself which I really appreciate, and a stop at findamazingoffers added a bit more context that fit naturally with what was already said here, no need to read everything twice to get the point being made today.
Appreciated how the post felt complete without overstaying its welcome, and a stop at bravoflow 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.
Great work on keeping things readable, the post never drags or repeats itself which I really appreciate, and a stop at spryshelf added a bit more context that fit naturally with what was already said here, no need to read everything twice to get the point being made today.
Worth recognising that this site does not chase the daily news cycle, and a stop at nightfallmarketplace confirmed the longer publication arc, sites that resist the pressure to comment on every passing event are sites with genuine editorial discipline and this one has clearly chosen depth over volume which I respect deeply.
Honest take is that this was better than I expected when I clicked through, and a look at spryshelf reinforced that, the bar for online content has dropped so much that finding something thoughtful and well constructed feels almost noteworthy now which says more about the average than about this site itself.
Halfway through reading I knew this would be one to bookmark, and a look at velvetfieldmarket 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 I gave this a chance rather than scrolling past, and a stop at easyonlinepurchases confirmed I made the right call, sometimes the best content is hidden behind unassuming headlines that do not scream for attention and learning to slow down and check those out has paid off many times now across years of reading.
Worth saying that the quiet confidence of the writing is what landed first, and a look at premiumgoodsarena continued that quiet quality, confident writing without the loud display of confidence is a rare combination and this site has clearly developed both the knowledge and the editorial restraint to land that combination consistently.
Even from a single post the editorial care is clear, and a stop at bosonlab extended that care across more pages, the kind of attention to quality that shows up in every paragraph is what separates serious sites from the rest and this one has clearly invested in that paragraph level attention across what I have read.
I came here looking for a quick answer and ended up reading the whole post because it was actually interesting, and after swiftgain I had a much fuller picture, no stress and no confusion just a clear walk through the topic that made everything fall into place without much effort.
Over the course of reading several posts here a pattern of quality has emerged, and a stop at stylishbuycorner confirmed the pattern, the difference between sites that hit quality occasionally and sites that hit it consistently is huge and this site has clearly demonstrated the consistent kind through what I have read this morning.

Stands apart from similar pages by actually being useful, that is high praise these days, and a look at modernlifestylecorner kept that standard going, you can tell when a site is built around the reader versus around metrics and this one clearly belongs to the first category for sure based on what I read.
Looking forward to seeing what gets published next month, and a look at findyourwayforward extended that anticipation across the broader site, finding myself looking forward to a sites future content rather than just consuming its existing content is a stronger commitment level than I usually reach with new finds and this site triggered that.
Once I trust a site this much I tend to read everything they publish and that is the trajectory I am on with this one, and a stop at premiumgoodsarena confirmed the trajectory, the rare progression from interested reader to comprehensive reader is something only certain sites earn and this one is earning that progression rapidly.
Appreciated the way each section connected smoothly to the next without abrupt jumps, and a stop at flickreef kept that flow going nicely, transitions are something most blog writers ignore but the difference is huge for the reader who is trying to follow a sustained line of thought today across many different topics.

Really thankful for posts that respect a reader’s time, this one does, and a quick look at bettershoppinghub was the same, no need to scroll through endless intros just to get to the actual content, that approach alone is enough reason to come back here regularly for the kind of writing offered.
Well done, the kind of post that makes you slow down and actually read instead of skimming for keywords, and a look at finduniqueoffers kept me reading carefully too, that is a sign of writing that has been crafted rather than churned out for an algorithm to see today and tomorrow.
Appreciated that the writer trusted the reader to follow along without constant restating of earlier points, and a look at arcscout continued that respect for the reader, treating an audience as capable adults rather than as people to be hand held through every paragraph is something I notice and value highly across the open internet today.
Found this through a friend who recommended it and now I see why, and a look at everydayvaluezone only strengthened that recommendation in my own mind, word of mouth still works for content that actually delivers and this site is clearly earning recommendations the old fashioned way through quality rather than marketing.
Now thinking about this site as a small example of what good independent writing looks like, and a stop at buzzlane continued that exemplary status, the few sites that serve as good examples are sites worth holding up in conversations about quality and this one has earned that exemplary placement through patient consistent effort over time.

Reading this prompted me to subscribe to my first newsletter in months, and a stop at modernlifestylecorner 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.
A slim post with substantial content per word, and a look at happylivingmarket maintained the same density, the content per word ratio is something I track informally and this site scores high on that ratio compared to most sources I read regularly which is a quiet indicator of careful editorial work behind the scenes.
Thank you for being clear and direct, that simple approach saves so much frustration on the reader’s end, and a stop at wildcrestcorner only made me more sure of it, the rest of the content seems to follow the same pattern which is a great sign of consistent editorial care behind the scenes.
Came in confused about the topic and left with a much firmer grasp on it, and after arctools I felt I could explain this to someone else without hesitation, that is the gold standard for any educational content and most sites simply fail to reach it ever which is unfortunate but true.
Worth recognising the absence of the usual blog tropes here, and a look at orbdust continued that fresh quality, sites that avoid the standard moves of the medium read as more original even when the content is on familiar topics and this one has clearly chosen its own path through the conventional terrain skilfully.
Really appreciate this kind of writing, no shouting and no clickbait headlines just steady useful content, and a quick look at freshtrendcollection kept that going, definitely a site I will be returning to whenever I need a sensible take on similar topics in the days ahead and also during slower work weeks.

Started a draft response in my head and ended without publishing it because the post said it well enough, and a look at orbitway produced the same effect, content that satisfies my urge to add to it by being complete enough on its own is rare and represents a particular kind of editorial completeness here.
Picked a single sentence from this post to remember, and a look at yourtimeisnow gave me another to keep, content that produces memorable lines is doing more than just transferring information and the small selection of sentences I keep from each reading session is one of the actual returns I get from reading carefully.
