Just How Bad Is CXL Memory Latency?
Conventional wisdom says that trying to attach system memory to the PCI-Express bus is a bad idea if you care at all about latency. …

Samsung Shows Off CXL Server Memory Expander
People have been talking about CXL memory expansion for so long that it seems that it should be here already, but with the dearth of CPUs that can support PCI-Express 5.0 peripherals we have to be patient a little bit longer. …

Microsoft Azure Blazes The Disaggregated Memory Trail With zNUMA
Dynamic allocation of resources inside of a system, within a cluster, and across clusters is a bin-packing nightmare for hyperscalers and cloud builders. …

Thanks For The Memories
It is probably a myth that Bill Gates said “640 KB ought to be enough,” and whether or not he said it the truth is that it has never been enough. …

Systems To Morph As Memory Options Expand
Compute is by far still the largest part of the hardware budget at most IT organizations, and even with the advance of technology, which allows more compute, memory, storage, and I/O to be crammed into a server node, we still seem to always want more. …

Future Systems: What Will Tomorrow’s Server Look Like?
We can talk about storage and networking as much as we want, and about how the gravity of data bends infrastructure to its needs, but the server – or a collection of them loosely or tightly coupled – is still the real center of the datacenter. …

There Is No Such Thing As Memory Performance
Petar Radokjovic, who leads the memory systems division at the Barcelona Supercomputer Center, described his desk, messy with the latest research on next-generation memory systems for high performance computing, and says that for a time, the sight of them was enough to give him an ulcer. …
