Compania VMS Software, care acum cinci ani a achizi\u021bionat de la Hewlett-Packard drepturile de continuare a dezvolt\u0103rii sistemului de operare OpenVMS (Virtual Memory System), a publicat versiunea OpenVMS 9.1, notabil\u0103 prin implementarea suportului pentru arhitectura x86-64. Sistemul de operare OpenVMS s-a dezvoltat din 1977 \u0219i este utilizat \u00een sisteme rezistente la defec\u021biuni, care necesit\u0103 o fiabilitate sporit\u0103, fiind disponibil anterior doar pentru arhitecturile VAX, Alpha \u0219i Intel Itanium. Este demn de remarcat c\u0103 \u00eencerc\u0103rile de portare a OpenVMS pe sisteme x86 la sf\u00e2r\u0219itul anilor 1980 nu au avut succes din cauza \u00eentreruperii finan\u021b\u0103rii, moment \u00een care autorul portului a trecut la Microsoft \u0219i a creat Windows NT. <\/p>\n

Portul propus OpenVMS pentru arhitectura x86-64, pe l\u00e2ng\u0103 instalarea pe hardware real, suport\u0103 utilizarea \u00een virtu\u00e1lne ma\u0161ini<\/a> KVM, VMware \u0219i VirtualBox. Portul este construit pe baza acelora\u0219i coduri surs\u0103 OpenVMS care sunt utilizate \u00een versiunile pentru arhitecturile Alpha \u0219i Itanium, folosind compilarea condi\u021bionat\u0103, care \u00eenlocuie\u0219te func\u021biile legate de particularit\u0103\u021bile arhitecturilor hardware. <\/p>\n

Codul OpenVMS este adaptat pentru a fi compilat folosind LLVM \u00een locul compilatorului proprietar GEM, utilizat pentru compilarea porturilor Alpha \u0219i Itanium (a fost scris un translator special care reflect\u0103 GEM IR \u00een LLVM IR, iar Clang a fost adaptat pentru a compila codul C++ pentru OpenVMS). UEFI \u0219i ACPI sunt folosite pentru determinarea \u0219i ini\u021bializarea hardware-ului, iar un disk RAM este folosit pentru \u00eenc\u0103rcare \u00een locul mecanismului de boot special VMS, specific pentru hardware. Pentru a emula nivelurile de privilegii lips\u0103 VAX, Alpha \u0219i Itanium, care nu sunt disponibile \u00een sistemele x86-64, un modul SWIS (Software Interrupt Services) este folosit \u00een nucleul OpenVMS.
