Fast forward to the 2000s, which saw a huge boom in the number of processors working in parallel, with numbers upward in the tens of thousands. Such examples in the evolution in parallel computing, High Performance Computing, and multi-core systems include the fastest supercomputer today, which is Japan's Fugaku. It boasts an impressive 7.3 million cores, all of which are, for the first time in a supercomputer, ARM-based. It uses a hybrid-memory model and a new network architecture that provides higher cohesion among all the nodes. The success of the new system is a radical paradigm-shift from the departure of traditional supercomputing towards that of ARM-powered systems. It is also proof the designers wanted to highlight that HPC still has much room for improvement and innovation.
== How multicore products were marketed ==
Since multicore systems offered a lot of extra processing power compared to the output of a single core processor, many companies were leaping at the opportunity to gain more power for their servers at the time. To capitalize on this, IBM started development of the first dual-core processor on the market, which became available on the market was the IBM POWER4 in 2001. It became highly successful and gave IBM a very strong foothold in the industry when sold as part of their eServer pSeries server, the IBM Regatta. They iterated more on the POWER series of processors, and in 2010, expanded the number of cores available from 2 to 8 with the release of the POWER7.
While IBM was dominating the market for server CPUs, there was still a hole in the market for integrating multicore into desktop computers. In may of 2015, AMD was the first company to release a dual-core desktop CPU, the Athlon 64 x2. With the cheapest in the line being $500 and the most powerful being $1000, It did not quite match IBM’s “twice the performance for half the cost”. However, they were still another large innovation in the industry by AMD, and a top competitor for the highest power CPU on the market.
