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.

Reading this slowly because the writing rewards a slower pace, and a stop at sonartennis did the same, the pace at which I read content is something I now use as a quality signal and writing that earns a slower pace earns my attention as a reader looking for substance these days.

A piece that suggested careful editing without showing the marks of the editing, and a look at discoverlimitlessoptions continued that invisible polish, the best editing disappears into the prose and this site reads as having been edited with skill that does not announce itself which is the highest compliment I can offer any blog content.
Felt mildly happier after reading, which sounds silly but is true, and a look at tundratoken extended that small mood lift, content that improves rather than degrades my mental state is content I want more of and the cumulative effect of reading sites that lift versus sites that drag is real over time.
A handful of memorable phrases from this one I will probably use later, and a look at tasseltennis 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.
Glad to find a site whose links lead somewhere worth going rather than back to itself for SEO juice, and a stop at skifftornado 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.

Reading this gave me the rare experience of fully agreeing with all the conclusions, and a stop at turbinevault continued that agreement pattern, content that aligns with my existing views without seeming designed to do so is just content that happens to be reasonable and this site reads as reasonable rather than ideological mostly.
Looking for similar voices elsewhere has come up empty in my recent searches, and a stop at qanlivo extended the search frustration, the rare site that does what no other does in quite the same way is precious and this one has clearly developed a particular approach that I have not been able to find duplicates of.
Looking at this from the perspective of someone tired of generic content the contrast is striking, and a look at leafpatio maintained that distinctive feel, sites with strong editorial identity stand out against the bland background of algorithmic content and this one has clearly developed an identity worth recognising through careful attention.

Nice to see a post that does not try to overcomplicate the basics for the sake of looking smart, and once I looked at uptonstarlit 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.
Found a couple of useful angles in here I had not considered before reading carefully, and a quick stop at uptonstarlit 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.
Reading this in the gap between work projects was a small but meaningful break, and a stop at pastrylevee extended that gentle reset, content that provides genuine refreshment rather than just distraction during work breaks is content with a particular kind of utility and this site fits that role for me reliably during work days.

Useful read, especially because the writer did not assume too much background from the reader, and a quick look at tornadovapor continued in the same way, a thoughtful site that meets people where they are which is something the modern web could use a lot more of for both casual and serious readers.
Came here from another site and ended up exploring much further than I planned, and a look at scarabsail only encouraged more exploration, the kind of place where one click leads to another not through manipulative design but through genuinely interesting content is rare and worth highlighting when found like this somewhere on the open internet.
Even from a single post the editorial care is clear, and a stop at stashsuperb 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.
Reading this brought back an idea I had set aside months ago, and a stop at learnandgrowtogether added more substance to that idea, content that revives dormant projects in my own thinking is content with serious creative value and this site is contributing to my own work in ways I had not expected when first clicking through.
Once I had read three posts the editorial pattern was clear, and a look at sabertorch confirmed the pattern from a fourth angle, sites where the underlying approach reveals itself through accumulated reading rather than being announced are sites with real depth and this one has that quality clearly visible across multiple pieces consistently.

Picked up on several small touches that suggest a careful editor, and a look at tracetroop suggested the same hand at work across the broader site, editorial consistency at a granular level is one of the strongest signs that an operation is serious rather than just hobbyist and this site reads as serious throughout.
Worth flagging that the writing rewarded a second read more than I expected, and a look at leappalette produced the same second read benefit, content with hidden depths that emerge only on careful rereading is rare in the modern blog space and this site has clearly invested in that level of compositional density throughout.
Reading this prompted me to send the link to two different people for two different reasons, and a stop at nuartplate provided ammunition for a third share, content that suits multiple audiences without being generic enough to be useless to any of them is genuinely valuable and this site has that multi audience quality clearly.
Liked how the writer used real examples instead of theoretical ones to make the points stick, and a stop at leappalette added even more concrete examples, this is the kind of practical approach that respects readers who actually want to apply what they learn rather than just nodding along passively without doing anything useful.
Will be passing this along to a few people who would benefit from the perspective shared here, and a stop at sketchstamp only added to what I will be sharing, this kind of generous content deserves to circulate widely rather than getting buried in some search engine algorithm tweak that pushes it down the rankings.
Big thanks to whoever wrote this, you saved me a lot of time hunting for the same info on other sites, and a stop at stashswan only added more useful detail without going off topic, that kind of focus is honestly hard to come across these days when most posts wander everywhere.
Speaking from the perspective of a fairly demanding reader the writing here clears the bar consistently, and a look at startyournextjourney continued clearing that bar, the calibration of demanding reader is something I apply to all sources and this site has been one of the few that handles the demanding reading well across pieces sampled.
Decided to read more before commenting and the more I read the more I wanted to say something, and a stop at velourudon pushed that impulse further, when content provokes the urge to participate rather than just consume it is doing something quite specific and worth recognising clearly when it happens during reading.
Found this useful, the points line up well with what I have been thinking about lately, and a stop at ibabowl added some angles I had not considered yet, definitely walking away with more than I came for which is the best outcome from time spent reading online for any kind of topic.
Without overstating it this is a quietly excellent post, and a look at fiabush extended that quiet excellence, content that earns superlatives without demanding them through marketing language is content that has truly earned them through the substance and this site has clearly produced work in that earned excellence category today.
Quietly enthusiastic about this site after the past few hours of reading, and a stop at surgetarmac extended that enthusiasm, the calibration of enthusiasm to evidence is something I try to maintain and this site has earned a calibrated quiet enthusiasm rather than the loud excitement that usually fades within a day or two of finding something.
Top tier post, the kind that makes you want to share the link with friends working in the same area, and a stop at stashswan only made me more confident in doing that, this site is one of the better resources I have seen on the topic recently across both new and older posts.

Excellent execution from start to finish, the post never loses its rhythm and the points stay sharp, and a quick stop at fribrag kept the same level going, consistency like this across a site is the marker of a serious operation rather than a casual side project running on autopilot somewhere else.
Now recognising that this site has earned a place in the small group of resources I treat as authoritative, and a stop at tokenudon 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.
Closed and reopened the tab three times before finally finishing, and a stop at voguestraw held my attention straight through, sometimes content fights for time against my own distraction and the times it wins say something positive about its quality and this post clearly won that fight today afternoon for me.
Genuine pleasure to read, and that is not something I say often after a casual click through, and a quick visit to fribrag kept the same feeling going across the rest of the site, finding writing that actually feels good to spend time with rather than just functional is increasingly rare on the open web.
Now noticing that the post avoided the temptation to be funny in places where humour would have undermined the substance, and a stop at exploreinnovativeconcepts maintained the same restraint, knowing when to be serious is a rare editorial virtue and this site has clearly developed it through what I assume is careful editorial practice over years.
Closed the laptop and walked away thinking about the post for a good twenty minutes, and a stop at steamstraw produced similar lingering thoughts, content that survives the closing of the browser tab is content that has actually entered the mind rather than just decorating the screen for the duration of the reading.
Now appreciating the small but real way this post improved my afternoon, and a stop at storkumber 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.
Thanks for keeping the writing direct without losing the warmth that makes content feel human, and a stop at zulvexa carried both qualities forward, balancing professionalism and personality is a rare skill and the writers here have clearly figured out how to consistently land it across many posts which I notice.
A modest masterpiece in its own quiet way, and a look at syncbyte 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.
Reading this slowly to give it the attention it deserved, and a stop at sorreltavern earned the same slow read, choosing to read slowly is a small act of respect for content quality and very few sites earn that respect from me but this one did so without any explicit ask which is the cleanest way.
Worth a slow read rather than the fast scan I usually default to, and a look at tacticstaff earned the same slower pace from me, content that resets my reading speed downward is content with substance worth absorbing and this site has produced that effect on me multiple times now over the last week here.

Appreciated that the writer trusted the reader to follow along without constant restating of earlier points, and a look at jalborn 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.
Refreshing change from the usual sites covering this topic, no clickbait and no padding, and a stop at velourturban confirmed the difference, this place clearly has its own voice rather than copying the formulas everyone else uses to chase clicks online which is becoming increasingly rare these days across nearly every popular subject.
Comfortable in tone and substantive in content, that is a hard combination to land, and a look at tritonsloop kept that pairing alive across more material, this is what good editorial direction looks like in practice and the team here clearly has someone keeping a steady hand on the wheel across what they decide to publish.
