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.
A piece that built up gradually rather than front loading its main points, and a look at yourtimeisnow maintained the same gradual structure, content that trusts the reader to reach conclusions through accumulating reasoning is more persuasive than content that announces conclusions and then defends them and this site uses the persuasive approach.
Started thinking about my own writing differently after reading, and a look at musebeat continued that reflective effect, content that influences how I work rather than just informing what I know is content with the highest kind of impact and this site has triggered some of that reflective influence today on me.
Looking forward to seeing what gets published next month, and a look at futuregrovegallery 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.
Liked the natural conversational tone throughout, never stiff and never overly casual either, and a stop at foxarbor kept that comfortable middle ground going, finding a tone that respects the reader without becoming distant or overly familiar is harder than it sounds and this site nails that balance consistently across many different pieces.
A well calibrated piece that knew its scope and stayed inside it, and a look at epicinlet maintained the same scope discipline, scope creep is one of the failure modes of long blog posts and this site has clearly invested in the editorial discipline to prevent it which shows up in tightly contained pieces.
Found a couple of useful angles in here I had not considered before reading carefully, and a quick stop at dreamharbortrends added more, this is one of those sites where the value compounds the more you read rather than peaking at one viral post and then offering nothing else of substance afterwards which is common.
Better than most of the writing I have come across on this topic recently, simpler and more direct, and a look at isleparish continued in that same way, a real outlier in a crowded space full of repetitive content that says little while taking up a lot of reader time today which is unfortunate.
Adding this site to my regular reading list, the post earned that on its own, and a quick stop at edenfair sealed the decision, the kind of place worth checking back with from time to time because it consistently produces material that holds up against a critical reading too which I really value.
Reading this fit naturally into my afternoon walk because I was reading on my phone, and a stop at modernhomeculture continued well in that walking format, content that survives mobile reading without becoming awkward is content with format flexibility and this site has clearly thought about how it reads across different devices today.
Yesterday I was complaining about the state of online writing and today this site has temporarily fixed that complaint, and a look at mythmanor extended that mood reversal, the short term mood improvement that comes from finding good content is real and this site has produced that improvement for me at a useful moment.
Now planning to write about the topic myself eventually using this post as a reference, and a look at yourpotentialawaits would also serve in that future piece, content that becomes raw material for my own writing rather than just informing my reading is content with multiplicative value and this site is generating that multiplicative effect.
I really like how the writer keeps the tone friendly without sounding fake or overly polished, and after a stop at northernwavegoods the same calm pace was there, no rushing to make a point and no padding either, just clean honest writing that I can respect and come back to later again.
The lack of unnecessary jargon made the post accessible without sacrificing accuracy, and a look at ivypier continued in the same accessible style, technical topics often hide behind specialised vocabulary but here the writer trusts the reader to keep up with plain language and that trust pays off nicely throughout the entire post.

A piece that exhibited the kind of patience that good writing requires, and a look at flowlegend continued that patient quality, hurried writing is easy to spot and this site reads as having been written without time pressure which produces a different feel than the rushed content that dominates much of the modern blog space.
Left me wanting to read more rather than feeling burned out, that is a good sign, and a look at northernwavegoods confirmed there is plenty more here to explore, the kind of writing that builds appetite rather than killing it which is a rare quality on the modern open internet today across most categories of content.
A piece that did not lean on the writer credentials or institutional backing, and a look at globalmarketoutlet maintained the same focus on substance, content that earns trust through quality rather than through name dropping is the kind I find most persuasive and this site is clearly playing on the substance side of that distinction.
Reading this between meetings turned out to be the most useful thing I did all afternoon, and a stop at trueharborboutique kept that productivity feeling going, content can sometimes outperform actual work in terms of what gets accomplished mentally and this site managed that today which is genuinely a high bar to clear consistently.
Now recognising the specific pleasure of reading writing that shows real care for sentence shapes, and a look at ivypier extended that craft pleasure, sentence level writing quality is something most blog content ignores entirely and this site has clearly invested in the prose layer alongside the substance which is rare today.
I am really inspired along with your writing skills and also with the structure on your weblog.
Is that this a paid theme or did you customize it yourself?
Either way stay up the nice high quality writing, it’s uncommon to see a nice blog like this one these days..
Time spent here today felt productive in the way that good reading sessions sometimes do, and a stop at trueharborboutique extended that productive feeling across the rest of the morning, the difference between productive reading and merely passing time is real and this site is consistently on the productive side for me lately.
Quietly enjoying that I have found a new site to follow for the topic, and a look at globalinspiredclickping reinforced the small pleasure of the find, the discovery of new high quality sources is one of the more durable pleasures of careful internet reading and this site has been generating that discovery pleasure at multiple points already today.
Thanks for the breakdown, it gave me a clearer picture of something I had been confused about for a while now, and a stop at freshpineemporium closed the remaining gaps in my understanding nicely, no need to hunt around twenty other articles to put the pieces together which is a real time saver.
The depth of coverage felt about right for the format, neither shallow nor overwhelming, and a look at lunacourts kept that calibration going, getting the depth right for blog format is genuinely difficult because too shallow loses experts and too deep loses beginners but this site nailed it nicely which I really do appreciate.
Definitely a recommend from me, anyone curious about the topic should check this out, and a look at etherfair adds even more reason for that, the depth and quality combine to make this site one I will be pointing people toward whenever similar conversations come up over the months ahead at work or socially.

Worth pointing out that the writing reads as confident without being defensive about it, and a look at yourdealhub extended that secure tone, content that does not pre emptively argue against imagined critics has a different quality from defensive writing and this site reads as written from a place of real ease.
Now planning to share the link with a small group of readers I trust, and a look at globalinspiredclickping suggested more material to share with the same group, recommending content into a curated circle requires confidence in the recommendation and this site is making me confident in those personal recommendations on multiple separate occasions now.
Liked everything about the experience, from the opening through to the closing notes, and a stop at coastalmistcorner 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.
I really like the calm tone here, it does not push anything on the reader, and after I went through meritquays I felt the same way, just steady useful content laid out without drama, which is exactly what someone trying to learn something quickly needs to find rather than aggressive marketing.
Worth your time, that is the simplest endorsement I can give, and a stop at discovergiftoutlet extends that endorsement across the rest of the site, this is one of those increasingly rare places that delivers on what it promises rather than over selling the content and under delivering on substance every time which I find frustrating elsewhere.
Now planning to come back when I have the right kind of attention to read carefully, and a stop at jetdome reinforced that plan, choosing the right moment to read certain content is a quiet form of respect for the work and this site is generating those careful planning behaviours from me consistently as a reader.
Most of the time I bounce off similar pages within seconds, and a stop at portpoises held me longer than I would have predicted, the ability to convert a likely bouncing visitor into an engaged reader is a quality signal and this site has demonstrated that conversion ability across multiple visits where I expected to bounce.
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 everwildbranch 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.
Worth recognising that the post did not pretend to be the final word on the topic, and a stop at coastalmistcorner continued that humility, content that admits its own scope and limits is more trustworthy than content that overreaches and this site has clearly developed the editorial maturity to know what it can and cannot claim well.
Now appreciating the small but real way this post improved my afternoon, and a stop at discovergiftoutlet 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.
Now recognising the specific pleasure of reading writing that shows real care for sentence shapes, and a look at rusticridgeboutique extended that craft pleasure, sentence level writing quality is something most blog content ignores entirely and this site has clearly invested in the prose layer alongside the substance which is rare today.
A modest masterpiece in its own quiet way, and a look at globalbuyzone confirmed the same quiet quality across the rest of the site, calling something a masterpiece is usually overstating but for content this carefully crafted the word feels appropriate even if the writers themselves would probably resist the label honestly.
Found the section structure particularly thoughtful, and a stop at neatlounge suggested the same care across the broader site, structural choices guide the reader through the material in ways most people do not consciously notice but feel the absence of when those choices are made carelessly or not at all.
Decided this was the best thing I had read all morning, and a stop at etherledge kept that ranking intact, ranking my reading is something I do mentally throughout the day and the top rank is competitive and not easily won but this site won it without needing to overstate its claims for that.
Now appreciating the small but real way this post improved my afternoon, and a stop at deepforestcollective 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.
Started reading without much expectation and ended on a high note, and a look at mythmanors continued that arc, content that builds rather than peaks early is a sign of a writer who knows how to structure a piece for sustained reader engagement rather than relying on a strong hook to do all the work.
Nice to see a post that does not try to overcomplicate the basics for the sake of looking smart, and once I looked at softwillowdesigns the same direct tone was there too, which honestly makes a difference when you are short on time and want answers without long pointless intros.
Now noticing that the post did not mention the writer at all, focus stayed on the topic, and a look at everattics continued that author absent quality, content that disappears the writer to focus on the substance is a particular kind of generosity and this site has clearly chosen the substance over the personality consistently.
Worth flagging this post as worth a careful read rather than a casual skim, and a stop at jetmanor 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.

Better than most of the writing I have come across on this topic recently, simpler and more direct, and a look at neatglyph continued in that same way, a real outlier in a crowded space full of repetitive content that says little while taking up a lot of reader time today which is unfortunate.
A piece that did not require external context to follow, and a look at yourdailyinspiration maintained the same self contained quality, content that stands alone without forcing readers to chase prerequisites is more accessible and this site has clearly thought about how each piece can serve a fresh visitor rather than only existing members.
Liked the careful selection of which details to include and which to skip, and a stop at globalbuyzone reflected the same editorial judgement, knowing what to leave out is just as important as knowing what to include and this site has clearly figured out where that line sits for the topics it covers regularly.
Really appreciate the lack of pop ups, modals, cookie banners stacking on top of each other, and a quick visit to forgecabin confirmed the same clean approach across the rest of the site, technical decisions about user experience are part of what makes content actually pleasant to engage with for sure.
