ROCm, a New Era in Open GPU Computing

Platform for GPU-Enabled HPC and Ultrascale Computing

Hardware to Play ROCm

ROCm Platform Supports Two Graphics Core Next (GCN) GPU Generations

Supported CPU

ROCm Platform Leverage modern CPU with support with PCIe Gen 3 which aslo support PCIe Atomics (Fetch ADD,Compare and SWAP, Unconditional SWAP, AtomicsOpCompletion) To find out more about’

When you install your GPU’s Make sure you install them on real PCIe Gen3 x16 or x8 lanes directly on CPU’s Root I/O controller or a PCIe Switch directly attached to the CPU’s Root I/O controller. We have seen many issue with Consumer motherboard which support Physical x16 Connectors, but the connector is electrically connected as PCIe Gen2 x4, if you see this it is typically hanging off the Southbridge PCIe I/O controller. If your motherboard is configured this way please do not use this connector for your GPU.

Current CPU which support PCIe Gen3 + PCIe Atomics are:
Curently Not supported

AMD Carrizo based APU have limited support due to OEM & ODM’s Carrizo enabled Laptop, All In One System and Desktop system had inconsistency in supporting the correct System BIOS configurations for ROCm driver enablement. Before you buy a Carrizo system to run ROCm. You should check the SBIOS to see if has an option to enable IOMMUv2. If this is enabled, next we need test for the correct CRAT Table support to properly configure the driver.
