IBM

As of 2018, IBM is considered to be the leader in the production of supercomputers, with HP being in second. It was announced that in early 2018 that the Oak Ridge National Laboratory is expected to deliver the newest IBM system named Summit. This machine is capable of reaching a peak of 200 petaflops. This would make the Summit about twice as fast as the TaihuLight if the claim is true. Summit will have IBM Power9 and Nvidia Volta GPUs. By only using about 3,400 nodes the Summit will deliver over five times the computational performance of the Titan’s 18,688 nodes. Each node in the Summit will contain over a terabyte of coherent memory. It will also contain over 800GB of non-volatile RAM that will serve as extended memory.

HP

Back in December of 2016, HP showed a working prototype of a new supercomputer with the name “the Machine”, which HP claimed at the time was the first demonstration of what is called memory-driven computing. HP Enterprise says that the simulations show that the memory driven computing can achieve improved speeds of 8,000 times faster than normal computers. The market for this supercomputer is most likely high end servers that companies use to bring Facebook and YouTube, and not intended for consumer PCs. In the future HP plans to develop systems with hundreds of terabytes of memory which would make the Machine more powerful. Also they are developing a new memory chip the memristor, which can retain information even when powered down.
