Scopul lucrării: 'tudierea metodelor de evaluare a performan(elor sistemelor de calculMetodele de evaluare se ba)ea)ă pe *'+ folosind mediul instrumental '+,et Tools de modelare#i validarea sistemelor cu prelucrare distructivă a datelor

Consieraţii teoretice:

n !eneral arhitectura 'M+ poate fi repre)entată ca o mul(ime de resurse: module primare.procesoare/ module secundare .memorii0 porturi de intrareie#ire/ cu re(ele de comunicare ce leconectea)ă Modulele primare sunt destinate prelucrării datelor #i repre)intă elemente de

 procesare a sistemului ce produc cereri pentru accesul prin re(eaua de comunicare către modulelesecundare capabile să deservească cererile !enerate sau să le i!nore)e n calitate de indice de

 ba)ă a performan(elor 'M+0 de obicei0 este primită putere de procesare0 e!ală cu numărul mediude procesoare active Ca activitate se subn(ele!e procesoarele neblocate la momentul dat de alte

 procesoare #i care nu sunt n a#teptare după resurse necesare pentru a continua prelucrareadatelor Astfel0 puterea de procesare poate fi scrisă sub forma:

unde 3 este mul(imea de stări 'M+0 n care procesoarele sunt active4 na!i" este numărul de procesoare active n starea i 4 5i este probabilitatea sta(ionară a stării i4 PP este puterea de procesare
