Microsoft’s supercomputer makes the TOP500 list, but the irony is that it doesn’t work with Windows, but with Linux

The TOP500 list it is published twice a year and records the most powerful supercomputers of the year. There has only been one change in the top ten, and it is one curious and with a little sneer.

This is the arrival of the Voyager-EUS2 supercomputer, which Microsoft Azure has developed and which has a power of 30 petaflops per second. All great, but the really funny thing is that Microsoft’s supercomputer doesn’t work with Windows, but Linux.

AMD wins integers, Linux continues to be the absolute protagonist in this segment

Those responsible for the TOP500 list themselves indicate that there has been very little change in those top positions and that Japan’s Fugaku supercomputer is still the most powerful in the world with its 7,630,848 cores and a staggering 442 petaflops per second.

In the TOP500 list they differentiate Linux from some distributions, but the share of this operating system dominates everything in the world of supercomputing.

Second place goes to the US supercomputer Summit, which is far from Fugaku with its 148.8 PFLOPS, and further still is Sierra, also from the US and which boasts a power of 94.6 PFLOPS. Our Marenostrum, in the BSC, is in position 74 and achieves a power of 6.47 PFLOPS.

Linux is the absolute leader in supercomputing, why not Windows or macOS?

The most striking arrival is probably that of the aforementioned Microsoft Azure supercomputer, called Voyager-EUS2 and which has 253,440 cores and uses AMD EPYC 7V12 processors (each with 48 cores), but the (partial) surprise comes in its operating system: it is based on Linux.

It is as we say a partial surprise, because in the world of supercomputing it has long been the absolute protagonist is Linux, that for years It is present in absolutely all the supercomputers on the TOP500 list.

On this year’s list, the German JUWELS Booster Module supercomputer stands out, the eighth in the world with 44.1 PFLOPS. In processors “AMD is seeing a lot of successes”, and in fact The 15 most powerful supercomputers on that list are based on processors from AMD.

In the world of supercomputing, the United States (has 150 on the list) and China (173) are also the big standouts, and between them they have two out of three supercomputers of the list.
