Intel has released version 2.1 of XPU Manager, an open-source tool for monitoring Intel Arc Pro GPUs. This update matters to system administrators and developers who manage multi-GPU workloads because it adds detailed visibility into peer-to-peer communication paths. The new topology view helps users configure hardware for maximum data transfer efficiency without guessing which cards can talk directly to each other.

The software supports Ubuntu 24.04.3 and Ubuntu 26.04 for full functionality, while Windows Server 2022 and 2025 receive a limited set of XPU-SMI functions. Intel lists the Arc Pro Series GPUs as the primary supported hardware for this release. Users running these specific operating systems can now access the updated monitoring commands without compatibility issues.
The main feature in version 2.1 is a new P2P command that displays an N×N matrix of GPU pairs. This matrix shows which cards support peer read, peer write, MDF fabric, atomics, and PCIe access. Administrators can use this data to optimize memory sharing between GPUs in complex server configurations.
Intel also fixed several reporting bugs in this release. The tool now shows 0.0 for PCIe throughput when an accessible link is idle, instead of displaying N/A. ECC reporting separates correctable and uncorrectable errors for clearer diagnostics. GPU process memory usage is now read directly from the kernel's DRM accounting rather than being calculated from open file descriptors.
This update provides more accurate hardware telemetry for Intel Arc Pro deployments on Linux and Windows Server platforms. The changes improve the reliability of monitoring tools used in data center and workstation environments. Users can download the open-source software to manage their GPU resources with greater precision.
