The recent decision by the Compute Express Link (CXL) and Gen-Z consortiums to collaborate on their respective technologies is a positive development that is likely to accelerate the acceptance of both memory fabric standards. Although not strictly competing against one another, prior to the agreement there was no assurance that Gen-Z and CXL supported devices would be compatible on future hardware. With the Memorandum of Understanding (MOU) recently agreed to by the two organizations, a path forward for interoperability and other collaborations now exists.
DOE's recent announcement of the operational Summit supercomputer at Oak Ridge National Laboratory (ORNL) marks a shift in the global lead for supercomputer performance from China back to the United States.

The Department of Energy at Oak Ridge National Laboratory (ORNL) recently announced plans for the development of a 1.5 exaflops system called Frontier to be delivered in 2021. US HPC maker Cray and chip maker AMD are the two key US commercial partners in this effort. Despite numerous press articles centered on the 1.5 exaflops peak performance of Frontier, ORNL's original RFP released in April of 2018 clearly called out the diverse workload requirements that Frontier would have to successfully handle that span the traditional modeling and simulation sector, big data analysis, and AI applications, while demonstrating a 50X improvement in solving key DOE science problems that today run at the 20 petaflops level. To meet those ambitious goals, strong support from DOE's companion $1.7 billion Exascale Computing Project (ECP) will be critical.
