Intel, Google and Microsoft are among nine tech giants who have teamed up to launch a new industry group to advance data centre performance. The group, which also includes Alibaba, Cisco, Dell EMC, Facebook, HPE and Huawei, is looking at solidifying Compute Express Link (CXL), an emerging high-speed CPU-to-device and CPU-to-memory interconnect. The particular focus is on high performance computing (HPC) and artificial intelligence (AI) workloads among others. The companies confirmed in a statement that it had ratified the CXL Specification 1.0, built on PCI Express infrastructure which aims to offer breakneck speeds while supporting an ecosystem which enables even faster performance going forward. The press materials outlined how CXL worked. “CXL technology maintains memory coherency between the CPU memory space and memory on attached devices, which allows resource sharing for higher performance, reduced software stack complexity, and lower overall system cost,” the compani...
