Proiectul care dezvolt\u0103 microkernelul deschis seL4 a primit premiul ACM Software System Award, acordat anual de Asocia\u021bia pentru Calcul (ACM), cea mai autoritar\u0103 organiza\u021bie interna\u021bional\u0103 \u00een domeniul sistemelor informatice. Premiul a fost acordat pentru realiz\u0103rile \u00een domeniul demonstra\u021biei matematice a fiabilit\u0103\u021bii oper\u0103rii, care dovede\u0219te conformitatea complet\u0103 cu specifica\u021biile definite \u00een limbaj formal \u0219i recunoa\u0219te preg\u0103tirea pentru utilizarea \u00een aplica\u021bii critice. Proiectul seL4 a demonstrat c\u0103 este posibil s\u0103 se efectueze o verificare formal\u0103 complet\u0103 a fiabilit\u0103\u021bii \u0219i securit\u0103\u021bii pentru proiecte la nivelul sistemelor de operare industriale, f\u0103r\u0103 a compromite performan\u021ba \u0219i versatilitatea. <\/p>\n

Premiul ACM Software System Award este \u00eenm\u00e2nat anual pentru dezvoltarea sistemelor software care au avut un impact definitoriu asupra industriei, introduc\u00e2nd concepte noi sau descoperind noi domenii de aplicare comercial\u0103. Valoarea premiului este de 35 de mii de dolari SUA. \u00cen anii anteriori, premiile ACM au fost acordate proiectelor GCC \u0219i LLVM, precum \u0219i fondatorilor lor Richard Stallman \u0219i Chris Lattner. De asemenea, au fost recunoscute proiecte \u0219i tehnologii precum UNIX, Java, Apache, Mosaic, WWW, Smalltalk, PostScript, TeX, Tcl\/Tk, RPC, Make, DNS, AFS, Eiffel, VMware, Wireshark, Jupyter Notebooks, Berkeley DB \u0219i Eclipse. <\/p>\n

Arhitectura microkernel-ului seL4 este remarcabil\u0103 prin separarea p\u0103r\u021bilor pentru gestionarea resurselor nucleului \u00een spa\u021biul utilizatorului \u0219i aplicarea acelora\u0219i instrumente de delimitare a accesului pentru aceste resurse, ca pentru resursele utilizatorului. Microkernel-ul nu ofer\u0103 abstractiz\u0103ri \u00eenalte pentru gestionarea fi\u0219ierelor, proceselor, conexiunilor de re\u021bea etc., ci ofer\u0103 doar mecanisme Minime pentru gestionarea accesului la spa\u021biul de adresare fizic, \u00eentreruperi \u0219i resurse ale procesorului. Abstractiz\u0103rile \u00eenalte \u0219i driverele pentru interac\u021biunea cu hardware-ul sunt implementate separat deasupra microkernel-ului sub form\u0103 de sarcini, care sunt executate la nivel de utilizator. Accesul acestor sarcini la resursele disponibile ale microkernel-ului se organizeaz\u0103 prin definirea regulilor.
