Nel risolvere determinati problemi, Parker ricorda il progetto Multikernel presentato alcuni giorni fa, ma si differenzia da esso per architettura e implementazione.    <\/p>\n<p>In Parker viene applicata una suddivisione dei kernel CPU, della memoria e dei dispositivi esistenti. Ogni istanza di kernel avviata si basa su un'unica immagine del kernel comune, ma pu\u00f2 utilizzare impostazioni e ottimizzazioni diverse. Il primo kernel caricato (Boot Kernel) gestisce la distribuzione e la suddivisione dei dispositivi hardware. Le altre istanze del kernel Linux (Application Kernel) lavorano solo con i kernel CPU, la memoria e i dispositivi di input\/output ad esso associati.     <\/p>\n<p>Nella variante iniziale, al fine di ridurre i costi e semplificare l'implementazione, manca un meccanismo di gestione e tutti i kernel utilizzano un'unica area di isolamento (domain), cio\u00e8 un errore in qualsiasi istanza del kernel pu\u00f2 causare problemi all'intero sistema. In futuro si prevede di sfruttare capacit\u00e0 hardware separate per isolare le istanze del kernel. Come applicazione di Parker vengono menzionati i computer con un elevato numero di core CPU, che affrontano problemi di scalabilit\u00e0 dei compiti.               <\/p>\n<p>Per la gestione, in Parker \u00e8 stato implementato un'interfaccia basata su kernfs, e per caricare istanze aggiuntive del kernel in aree di memoria riservate viene utilizzato kexec. Prima di avviare kernel aggiuntivi, il kernel primario libera i kernel CPU, riserva memoria fisica e scollega i dispositivi PCI per il loro utilizzo nel kernel suddiviso. Per l'input\/output, ogni kernel deve essere associato a un proprio dispositivo PCIe, come un'unit\u00e0 NVMe o un adattatore di rete. Dopo l'avvio, un'istanza del kernel non pu\u00f2 interagire con altri kernel.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
