Trabalho 2 – EPOS
Implementação de Idle-waiting
A implementação do exercicio 2, consiste em alteração da classe Syncronizer, onde na versão inicial a mesma utiliza yield gerando uma carga desnecessária para o processador. A alteração deve ser semelhante a realizada no exercicio um, fazendo com que não seja gasto recursos sem necessidade.
Durante as discussões sobre a implementação imaginamos uma nova váriavel dentro de cada Thread para monitorar se a mesma está em uma estrutura como Semaphoro, Mutex ou váriavel condicional. Assim sendo possivel a verificação se está ou não, permitindo que nós façamos as devidas verificações para que o método resume e suspend não possam ser chamados quando a mesma estivesse esperando. Após algum tempo discutindo e analise dos códigos foi imaginada uma abordagem que em vez de criar uma váriavel nova para cada Thread seria necessário simplesmente a criação de um novo estado, denominado por nós de WAITING. Junto a isso foi criada uma fila para cada “Synchronizer”, que possui os processos que estão esperando para serem acordados. Os métodos que acordam os outros processos (wakeup e wakeup_all) foram implementados de forma não bloqueante, ou seja, as threads acordadas são apenas colocadas na fila “_ready”, sem troca imediata de contexto.
Outras alterações também foram realizadas nos arquivos synchronizer.h, thread.cc, condition.h e semaphore.h, para que os mesmos funcionem corretamente com o novo estado WAITING. Por exemplo, no arquivo Thread.cc as implementações de Join, Resume e exit foram alteradas para a utilização deste novo estado, neste arquivo também foram criados novos métodos denominados sleep e wakeup. Que basicamente tratam a parte de colocar para dormir e botar neste novo estado e também na fila do “Synchronizer”. As devidas alterações foram realizadas nos demais arquivos, para que os mesmos funcionem com o novo estado WAITING.
Também implementamos o busy waiting no “Synchronizer”, para o usuário poder escolher entre busy e idle waiting alterando uma variável booleana.

Алкоголь является сильным наркотиком, зависимость формируется и на физиологическом, и на психологическом уровне, поэтому такое состояние требует комплексной работы сразу нескольких специалистов. Нарколог, врач общей практики, психолог, психотерапевт, психиатр и реабилитационный персонал помогают разобраться, почему человек начал пить, почему не может выйти из запоя самостоятельно, какие проблемы семьи усиливают употребление спиртного и нужна ли госпитализация. Главный вопрос при обращении — не только как быстро прокапаться, а как провести полный путь от детоксикации до устойчивой трезвости.

Многие люди, столкнувшись с проблемой алкогольной зависимости у родственника, пытаются справиться с похмельным синдромом при помощи аптечных сорбентов или народных методов. Однако при выраженной абстиненции такой подход неэффективен и опасен. Обезвоживание, нарушение электролитного баланса, сильные головные боли, головокружение и критическая нехватка витамина B1 требуют немедленного парентерального вмешательства. Только капельница от запоя способна за короткий срок восполнить дефицит жидкости, нормализовать сердечную деятельность и снять психоэмоциональное возбуждение, успокаивая нервную систему. Врачи центра работают круглосуточно, чтобы начать лечение максимально быстро. Оптимальный вариант купирования запоя — инфузионное вливание, которое проведет опытный нарколог, учитывая все особенности организма пациента.
