Compania chinez\u0103 ByteDance, care dezvolt\u0103 serviciul TikTok, a publicat \u00een lista de discu\u021bii pentru dezvoltatori a nucleului Linux patch-uri pentru implementarea sistemului Parker (PARtitioned KERnel), care permite rularea simultan\u0103 a mai multor nuclee Linux pe un singur computer, f\u0103r\u0103 a utiliza virtualizarea tradi\u021bional\u0103. \u00cen ceea ce prive\u0219te sarcinile rezolvate, Parker este similar cu proiectul Multikernel prezentat cu c\u00e2teva zile \u00een urm\u0103, dar se diferen\u021biaz\u0103 prin arhitectur\u0103 \u0219i implementare. <\/p>\n

\u00cen Parker se aplic\u0103 sec\u021bionarea nucleelor CPU existente, a memoriei \u0219i a dispozitivelor. Fiecare instan\u021b\u0103 de nucleu rulat\u0103 se bazeaz\u0103 pe o imagine comun\u0103 a nucleului, dar poate utiliza set\u0103ri \u0219i optimiz\u0103ri diferite. Nucleul ini\u021bial \u00eenc\u0103rcat (Boot Kernel) se ocup\u0103 de distribuirea \u0219i sec\u021bionarea resurselor hardware. Celelalte instan\u021be de nucleu Linux (Application Kernel) lucreaz\u0103 doar cu nucleele CPU, memoria \u0219i dispozitivele de intrare\/ie\u0219ire asociate. <\/p>\n

\u00cen varianta ini\u021bial\u0103, pentru a reduce costurile suplimentare \u0219i a simplifica implementarea, nu exist\u0103 un mecanism de gestionare, iar toate nucleele folosesc o singur\u0103 zon\u0103 de izolare (domain), ceea ce \u00eenseamn\u0103 c\u0103 o eroare \u00een orice instan\u021b\u0103 de nucleu poate duce la probleme \u00een \u00eentreaga sistem\u0103. \u00cen viitor, se pl\u0103nuie\u0219te utilizarea unor capacit\u0103\u021bi hardware separate pentru izolarea instan\u021belor de nucleu. Parker este men\u021bionat ca fiind aplicabil pentru computere cu un num\u0103r mare de nuclee CPU, unde apar probleme legate de scalarea sarcinilor. <\/p>\n

Pentru gestionare, \u00een Parker este implementat un interfa\u021b\u0103 bazat\u0103 pe kernfs, iar pentru \u00eenc\u0103rcarea instan\u021belor suplimentare de nucleu \u00een zonele de memorie rezervate se folose\u0219te kexec. \u00cenainte de a porni nucleele suplimentare, nucleul principal elibereaz\u0103 nucleele CPU, rezerv\u0103 memoria fizic\u0103 \u0219i deconecteaz\u0103 dispozitivele PCI pentru utilizarea lor \u00een nucleul sec\u021bionat. Fiecare nucleu trebuie s\u0103 aib\u0103 asociat un dispozitiv PCIe, cum ar fi un SSD NVMe sau un adaptor de re\u021bea, pentru intrare\/ie\u0219ire. Dup\u0103 pornirea instan\u021bei nucleului, aceasta nu poate interac\u021biona cu alte nuclee.
