Update on In-Field-Scan adventures: Following my message, Intel has now published In-Field-Scan "scan tests" firmware images for Emerald Rapids (Xeon 5th gen), and updated the Linux kernel documentation accordingly.
Still missing are the images for already released CPU families Sierra Forrest and Granite Rapids (Xeon 6th gen). 4th gen Xeon (Sapphire Rapids) won't have a public release of the scan tests firmware images.

They can still do the Array Built-In Self Tests (BIST) which require no firmware at all to test L1/L2 caches, register files, and (SRAM?) data arrays.

#Nvidia #GraceSuperchip loses to #Intel #SapphireRapids in #HPC performance #benchmarks, promises greater efficiency
Barcelona #Supercomputing and #SUNY published benchmarks showing Grace Superchip, couldn't quite match TWO 48-core Sapphire Rapids #CPU. Despite not having earth-shattering performance, Grace promises to be competitive datacenter and HPC processor thanks to its efficiency. Built on Arm architecture. A single Grace CPU comes with 72c and 480GB of LPDDR5X RAM

The rare moment Intel shows #EmeraldRapids MCC, while they never did for #SapphireRapids.

#Microsoft #Azure Eagle is a Paradigm Shifting Cloud #Supercomputer
While traditional #HPC clusters are built in places like national labs and access is limited to those who are approved by the institutions that run them, Microsoft’s is a cloud solution. With 14,400 #NVIDIA #H100 #GPU (14400/8 = 1800 nodes?), InfiniBand, and #Intel #Xeon #SapphireRapids #CPU, the new system turned in a #3 result only around 4% less than #2 on the November 2023 #Top500 list.

Seeing every review of #genoa #bergamo and #SapphireRapids coming out with #spr looking foolish is concerning but cathartic. #spr with #hbm being clowned on by #VCache is hard to not laugh about.
