UltraSPARC T4 tech summary
- patrickgzill 15y agoUnfortunately due to Oracle's behavior, it is completely irrelevant.
- bryanlarsen 15y agoI think Anandtech put it best. Paraphrasing: T4 is proof that Oracle has not yet abandoned SPARC and provides enough performance that those who are heavily invested in Solaris/SPARC won't feel obligated to look for an alternative. It probably won't convince anybody to switch to SPARC.
- maximilianburke 15y agoOracle has invented the Pentium 4! edit: 8 cores per die and 8 threads per core is neat but the high clock rate and the relatively small caches are going to make it a tricky beast to program for.
- wladimir 15y agoI have some experience programming against the previous architecture (T3). It depends on what you're doing. For some purposes it's great to have that many cores/thread, such as network servers or others systems that handle zillions of quasi-independent messages. On the other hand, if your software only have a few active threads that do heavy computation once in a while, it's very tricky (even the packaged BLAS libraries only have so-so performance, even though they parallelize heavily and are supposedly optimized for their caches) and IMO you're better off with a traditional multicore processor.
