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.

Solid recommendation from me to anyone working in the area, the perspective here is grounded, and a look at growththroughfocus adds even more useful angles, the kind of site that becomes a reference rather than just a one time read which is a higher bar than most blogs ever reach today on the modern web.
Really thankful for posts that respect a reader’s time, this one does, and a quick look at leafdawn 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.
Let me save you some serious time, learned this the hard way. You find this amazing deal online: brand new Beamer, unlimited miles, price that makes you smile. Plus they freeze a surprise $2500 on your card for a week right before giving you the keys. Eight years in South Florida and these clowns still almost get me. When you need a proper and reliable premium ride to cruise around, do some real digging first and read actual customer reviews. Miami without decent wheels is basically a hostage situation, especially since the AC must be arctic cold and unlimited miles non-negotiable.
I’ve run through maybe 45 rental companies across Dade, Broward, and Monroe, until I finally found one outfit that doesn’t play stupid games. If you are looking for the only honest source for premium wheels across South Florida, check the current details here: exotic car rental south beach fl exotic car rental south beach fl. Yeah, parking in South Beach will cost you a nice bottle of wine — but that’s the Miami tax. Just drive safe out there and absolutely skip that “windshield protection” upsell — pure profit for them, zero value for you. let me know if you guys have any other clean spots.

Strong recommendation from me, anyone curious about the topic should make time for this, and a look at advancewithclarity only sharpens that recommendation further, the kind of resource that holds up against careful scrutiny rather than crumbling at the first critical question is rare and worth pointing other people toward when the topic comes up.
Most of the time I bounce off similar pages within seconds, and a stop at cartwaymarket 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.

If I had encountered this site five years ago I would have been telling everyone about it, and a look at growthsteeringhub extended that retrospective enthusiasm, the version of me who used to recommend favourite blogs frequently would have made sure friends knew about this one and that earlier enthusiasm is partially returning to me here.
However many similar pages I have read this one taught me something new, and a stop at quickcartworld added more new material, content that contributes genuinely fresh information rather than recycling what is already widely available is content with real informational value and this site is providing that informational freshness at a notable rate.
