VMS Software, der k\u00f8bte rettighederne til fortsat udvikling af operativsystemet OpenVMS (Virtual Memory System) fra Hewlett-Packard for fem \u00e5r siden, har offentliggjort udgivelsen OpenVMS 9.1, som er bem\u00e6rkelsesv\u00e6rdig for implementeringen af st\u00f8tte til x86-64-arkitekturen. Operativsystemet OpenVMS har udviklet sig siden 1977 og anvendes i fejltolerante systemer, der kr\u00e6ver h\u00f8j p\u00e5lidelighed, og har tidligere kun v\u00e6ret tilg\u00e6ngeligt for VAX-, Alpha- og Intel Itanium-arkitekturerne. Det er bem\u00e6rkelsesv\u00e6rdigt, at fors\u00f8g p\u00e5 at portere OpenVMS til x86-systemer i slutningen af 1980'erne ikke var succesfulde p\u00e5 grund af stop for finansiering, hvorefter portens forfatter gik til Microsoft og skabte Windows NT. <\/p>\n

Den foresl\u00e5ede port af OpenVMS til x86-64-arkitekturen underst\u00f8tter udover installation p\u00e5 fysisk hardware ogs\u00e5 brug i virtuelle maskiner<\/a> KVM, VMware og VirtualBox. Porten er bygget p\u00e5 de samme kildekoder til OpenVMS, som anvendes i versionerne til Alpha- og Itanium-arkitekturerne, med betinget kompilering, der erstatter funktionerne relateret til hardwarearkitekturens s\u00e6rtr\u00e6k. <\/p>\n

Koden til OpenVMS er tilpasset til kompilering ved hj\u00e6lp af LLVM i stedet for den propriet\u00e6re compiler GEM, der anvendes til at bygge portene til Alpha og Itanium (en s\u00e6rlig overs\u00e6tter er skrevet for at overs\u00e6tte GEM IR til LLVM IR, og Clang er tilpasset til at bygge C++-kode til OpenVMS). For at bestemme og initialisere udstyret anvendes UEFI og ACPI, og til opstart er der brugt en RAM-disk i stedet for den specielle VMS boot-mekanisme, som er specifik for udstyret. For at emulere de manglende privilegieniveauer for VAX, Alpha og Itanium, som ikke findes i x86-64-systemer, anvendes en modul SWIS (Software Interrupt Services) i kernen af OpenVMS.
