A fost lansat\u0103 prima versiune public\u0103 a proiectului Multikernel Linux (mklinux-v7.0-mk2), care dezvolt\u0103 o variant\u0103 a nucleului Linux, ad\u0103ug\u00e2nd posibilitatea de a rula mai multe instan\u021be independente ale nucleului pe un singur computer fizic, f\u0103r\u0103 utilizarea hipervizoarelor \u0219i a virtualiz\u0103rii. Fiecare instan\u021b\u0103 a nucleului are acces direct la resursele hardware \u0219i poate fi utilizat\u0103 pentru a rula medii de sistem izolate separate. Prima versiune se bazeaz\u0103 pe nucleul Linux 7.0 \u0219i con\u021bine setarea de compilare «CONFIG_MULTIKERNEL», care, odat\u0103 dezactivat\u0103, face ca nucleul s\u0103 devin\u0103 complet identic cu nucleul standard 7.0. Din arhitecturile CPU este suportat momentan doar x86_64. <\/p>\n

Multikernel este prezentat ca un nou mecanism de izolare, ocup\u00e2nd o ni\u0219\u0103 \u00eentre virtualizarea cu hypervisor \u0219i izola\u021bia containerelor pe baz\u0103 de nucleu comun. Spre deosebire de virtualizare, Multikernel nu necesit\u0103 utilizarea unui hypervisor, simplific\u00e2nd crearea de medii pentru lansarea izolate a aplica\u021biilor individuale \u0219i permi\u021b\u00e2nd ob\u021binerea unor performan\u021be ridicate f\u0103r\u0103 suprasarcini legate de virtualizare. Spre deosebire de containere, Multikernel ofer\u0103 un nivel \u00eenalt de izolare \u0219i permite utilizarea unui nucleu separat \u00een fiecare mediu izolat, oprirea brusc\u0103 sau exploatarea unei vulnerabilit\u0103\u021bi \u00een care nu afecteaz\u0103 alte medii.

<\/center> <\/p>\n

Nucleul gazd\u0103 asigur\u0103 distribuirea CPU-urilor, memoriei \u0219i dispozitivelor PCI disponibile \u00eentre instan\u021bele suplimentare ale nucleului care func\u021bioneaz\u0103 \u00een paralel. Fiecare instan\u021b\u0103 ruleaz\u0103 pe un nucleu CPU dedicat, func\u021bioneaz\u0103 cu dispozitivele atribuite \u0219i are acces la o zon\u0103 dedicat\u0103 de memorie fizic\u0103. Execu\u021bia simultan\u0103 a mai multor nuclee se realizeaz\u0103 f\u0103r\u0103 virtualizare, folosind un handler SMP care distribuie CPU-urile disponibile. Este suportat\u0103 alocarea dinamic\u0103 a resurselor pentru mediile care ruleaz\u0103 \u0219i asigurarea unei performan\u021be predictibile. <\/p>\n

Datorit\u0103 elimin\u0103rii cheltuielilor de virtualizare, performan\u021ba utiliz\u0103rii Multikernel este evaluat\u0103 ca fiind aproape de performan\u021ba rul\u0103rii pe echipamente dedicate. Cu Multikernel, nu exist\u0103 etapa de transfer al controlului \u00eentre ma\u0219inile virtuale (VM exit), nu sunt folosite paginile de memorie de nivel secundar, un model de dispozitive separat \u0219i traducerea IOMMU. Comparativ cu hipervizorul, KVM<\/a> Utilizarea Multikernel-ului a dus la cre\u0219terea performan\u021bei diverselor apeluri \u0219i func\u021bii de sistem \u00eentre 1.07 \u0219i 2.5 ori (fork + exit — 1.07x, write() — 1.39x, AF_UNIX — 1.55x, Pipe — 2.18x, schimbarea contextului — 2.50x), iar l\u0103\u021bimea de band\u0103 \u0219i \u00eent\u00e2rzierea \u00een lucrul cu memoria sunt men\u021binute la acela\u0219i nivel.
