Un'altra Hammer story
In queste ultime settimane, l'interesse per Hammer è aumentato di giorno in giorno: anche oggi è stato pubblicato un articolo a riguardo, questa volta su Van's Hardware:
Lots of people have seen the block diagram of the 8 way hammer systems. So how about those little details that make it work?
Consider this. There are 8 blocks of local memory, each directly connected to a processor. And each processor can address the other processors' memory blocks via Hypertransport links. Stop yawning now.
So just how does this scheme work? Well, let's get into our own way-back machine and land in the days of the Intel 8086. Now some people recall that the 8086 was a 16-bit processor (more or less) with 20-bit addressing. The segment architecture had driven many a good person mad, so we'll skip the details.
