UALink Fires First GPU Interconnect Salvo At Nvidia NVSwitch

Compute engine makers can do all they want to bring the performance of their devices on par or even reasonably close to that of Nvidia’s various GPU accelerators, but until they have something akin to the NVLink and NVSwitch memory fabric that Nvidia uses to leverage the performance of many GPUs at bandwidths that dwarf PCI-Express switches and latencies that  dwarf Ethernet interconnects, they can never catch up.

The Dream Of Software Only Shared Memory Clusters

It is hard to quantify the amount of effort in systems and application software development that has been done precisely because there is no easy, efficient, and cheap way to make a bunch of cheap commodity servers look like one wonking system with a big ole flat memory space that is as easy to program as a PC but which brings to bear all that compute, memory, and I/O of a cluster as a single system image.

Cisco Connects With SGI For Big NUMA Iron

When supercomputer maker SGI tweaked its NUMA server technology to try to pursue sales in the datacenter, the plan was not to go it alone but rather to partner with the makers of workhorse Xeon servers that did not – and would not – make their own big iron but who nonetheless want to sell high-end machines to their customers.
