| dbo:abstract |
Rock (or ROCK) was a multithreading, multicore, SPARC microprocessor under development at Sun Microsystems. Canceled in 2010, it was a separate project from the SPARC T-Series (CoolThreads/Niagara) family of processors. Rock aimed at higher per-thread performance, higher floating-point performance, and greater SMP scalability than the Niagara family. The Rock processor targeted traditional high-end data-facing workloads, such as back-end database servers, as well as floating-point intensive high-performance computing workloads, whereas the Niagara family targets network-facing workloads such as web servers. (en) Rock (o ROCK) era il nome in codice di un microprocessore multithreading multicore in sviluppo presso la Sun Microsystems. Il microprocessore inplementava il set di istruzioni a 64 bit SPARC v9. Il mercato di riferimento del processore era i datacenter, i database server e tutte le unità che richiedono una elevata potenza di calcolo anche in virgola mobile. Il processore era dotato di una efficiente unità in virgola mobile (a differenza dell'UltraSPARC T1) e era dotato anche di un'unità che precaricherà il codice in modo da ridurre i tempi di attesa durante gli accessi alla memoria. Nel 2010 Sun Microsystem è stata acquisita dalla Oracle Corporation e nel maggio dello stesso anno l'amministratore delegato della stessa dichiarò di aver abbandonato il progetto del microprocessore. (it) Rock — многопоточный, многоядерный микропроцессор с системой команд SPARC, который разрабатывался компанией Sun Microsystems до её покупки Oracle Corporation. Это отдельная разработка, не связанная с семейством Niagara (UltraSPARC T1 и T2). Использование процессора Rock должно было увеличить производительность потоков и скорость вычислений с плавающей точкой по сравнению с процессорами семейства Niagara. Планировалось применять Rock в высокопроизводительных серверах, в частности, на серверах баз данных, а также для вычислений с плавающей точкой, тогда как процессоры Niagara предназначаются в основном для веб-серверов.
