This IBM® RedpaperTM publication introduces IBM PowerVM® Active MemoryTM Deduplication on IBM Power SystemsTM based on IBM POWER7® processor technology. Active Memory Deduplication is a virtualization technology through which memory pages with identical contents can be deduplicated in physical memory. This deduplication frees up physical memory positions so that more data can be held in memory at once. Memory deduplication is intended to work in a shared memory environment. Deduplication works with Active Memory Sharing, a technology through which multiple partitions on a system can share a pool of physical memory. Sharing this pool sometimes creates an overcommitment of this physical mem...

Vulcões são fascinantes. Suas erupções insistem em nos lembrar o poder da natureza e a vulnerabilidade da raça humana, contudo, a atividade vulcânica é um elemento essencial das forças que formam e constantemente reformam o nosso planeta. Neste livro, o cientista Dougal Jerram responde a questões como: O que são os vulcões? Como os vulcões se relacionam com as placas tectônicas e o movimento de continentes? Como eles afetam o clima da terra? É possível prever erupções? O autor também descreve no livro as erupções mais notáveis da história e os efeitos que causaram. Com 160 páginas, todos os dez capítulos são ilustrados com fotografias e diagramas coloridos. No fim apresenta-se um glossário de Vulcanologia de A a Z.
