SiPearl engaged on a large 72-core processor for supercomputers

A Twitter publish by a French politician inadvertently revealed particulars about SiPearl’s upcoming high-performance processor powered by Arm’s Neoverse Zeus cores. 

The SiPearl Rhea system-on-chip can be used for an experimental ‘in the direction of exascale’ supercomputer platform, with Rhea’s successor, SiPearl’s Cronos, used for the primary European exascale supercomputer. 

The SiPearl Rhea SoC is predicated on 72 Arm Neoverse Zeus cores and to that finish can be ready compete towards Amazon’s Graviton 2 and Ampere’s Altra processors. The processor additionally options 68 mesh community L3 cache slices together with varied IP blocks. Frequencies of the SoC in addition to cache sizes are unclear.

One of many significantly fascinating options of SiPearl’s Rhea is its reminiscence subsystem that depends on 4 HBM2E stacks that promise to supply a really excessive reminiscence bandwidth in addition to 4 or six DDR5 SDRAM controllers for further reminiscence capability. For the reason that chip makes use of 72 cores, it wants numerous RAM, so utilization of a hybrid reminiscence subsystem is justified.

At this time’s strongest supercomputer — Fugaku — is predicated on Fujitsu’s customized 48-core A64FX processor (primarily based on the ARMv8.2-A structure) that additionally makes use of HBM2 reminiscence, however doesn’t use extra conventional DDR4. 

The SoC is about to be made utilizing TSMC’s N7 manufacturing know-how, in accordance with the Twitter publish, however earlier SiPearl indicated that it’s going to use TSMC’s N6 fabrication course of that makes use of excessive ultraviolet (EUV) lithography. 

SiPeark expects to launch its Rhea processors generally in 2021 and use them to construct an experimental pre-ExaFLOPS-class machine. An much more superior household of SoCs named Cronos is about to emerge in 2022 or 2023 and they’ll energy exascacle supercomputers developed in Europe.
