Ampere¶
Work in Progress

The FTP provides access to Ampere Altra Max servers, offering a high-core-count ARM-based CPU platform for users who want to port, benchmark, or optimize code for the ARM architecture without the complexity of GPU offloading. These nodes are part of the ARM cluster.
All Ampere nodes are accessible via the ARM login node.
Hardware Overview¶
| Node type | Description | Queue |
|---|---|---|
| Altra Max (dual socket) | 2× Ampere Altra Max, up to 256 ARM cores per node | dual_a_max |
The Altra Max is a cloud-native ARM server processor built on the ARM Neoverse N1 architecture. With up to 128 cores per socket and a large number of PCIe lanes, it is designed for throughput-oriented workloads. Its high core count and power efficiency make it a suitable platform for evaluating the scalability of parallel applications on ARM.
Access¶
Ampere nodes are available to all FTP users. See the FTP overview for how to request access.
Using Ampere Nodes¶
Connect to the ARM login node and submit jobs to the dual_a_max partition:
Use sbatch or salloc to access the partition:
or, for interactive use:
Software for Ampere¶
Ampere Altra Max nodes support standard ARM-compatible compilers and libraries, including GCC, LLVM/Clang, OpenMPI, and OpenMP. The nodes are well-suited for testing the portability and scalability of existing HPC codes on ARM without any GPU-specific dependencies.
