#Europe’s #Jupiter #supercomputer hits #exascale threshold at inauguration
The long-awaited Jupiter system was officially inaugurated on Friday at the Jülich Supercomputing Center near Köln (Cologne) in #Germany, and has surpassed the exascale threshold of one quintillion (10¹⁸) operations per second. It comprises roughly 6000 compute nodes, each featuring four of #Nvidia's #GH200 #GraceHopper superchips, built by #Eviden the compute division of #Atos Group.

Oh look, #Nvidia makes CPUs now! And I got my hands on one! 🖖😋
Today I benchmarked #FluidX3D on Nvidia's #GH200, both #GPU and #CPU with #PoCL. Finally I can answer the question: How does that exotic 2-chip #HPC APU show up in #OpenCL?
--> It's 2 separate devices, a GPU with 94GB @ 4TB/s and a 72-core CPU with 480GB @ 384GB/s. The NVLink interconnect between the two is much faster than PCIe, achieving ~380GB/s host<->device bandwidth, only limited by poor misaligned VRAM BW on the GPU or RAM BW.
