If the machine has a “cray-mpich-abi” module available, you can try using that in combination with the SCM_USE_LOCAL_IMPI=1 environment setting. Read the MPICH ABI compatibility section in the Cray documentation for more information, and talk to your local system administrator. Cray users can use the IntelMPI version of AMS because it is binary-compatible with Cray MPI shared libraries. The OpenMPI runtime environment is distributed with AMS but it is limited to single-node (or desktop) usage.Ĭray XC. If you prefer to use the OpenMPI version instead, keep in mind that if you wish to run multi-node calculations you need to use a local copy of OpenMPI 4.1.1 with support for your batch system build in. The IntelMPI runtime environment is distributed with AMS.

It has been tested on both desktop and cluster machines and should work out-of-the-box on most cluster batch systems. We advise to use the IntelMPI version if possible. On 32-bit Windows ADF2017 can be used.Ĭhoose MPI (on Linux). AMS2022 is only supported on 64-bit Operating Systems (and hardware).

Mac OS X Mavericks and later (10.13+): x86-64 (64-bit) with OpenMPIģ2 vs.

Linux: x86-64 (64-bit): IntelMPI, OpenMPI, IntelMPI+CUDA (beta version only), IntelMPI optimized for AMD-Zen (Optimized for Ryzen/Threadripper/EPYC processors).

Currently, the following platforms are officially supported and available from our website:

A platform is a combination of the processor architecture, operating system, MPI implementation, and any other specialties such as CUDA or “MKL for AMD-Zen”. AMS is available for a number of platforms. You will only want to download it if you need to use the latest functionality not available in AMS2022.Ĭhoose a platform. The development snapshots page contains the latest developments. You may want to install a snapshot version if you know that some bugs have been fixed recently. The bug-fixed binaries contains the most recent bug fixes.

Normally, you will install the released version from the main download page.
