Hi, I’m new to the CMAQ-AWS environment. I successfully installed **IOAPI** and **CMAQ** on my parallel cluster, but I’m running into issues with **SMOKE**. When I try to run the `make` command, it throws multiple errors because it cannot find some files and libraries. I’ve tried on **two separate clusters** , but the problem persists on both. I would appreciate any guidance on: - How to properly install SMOKE on AWS clusters. - Any precompiled versions or alternative ways to run SMOKE without manual compilation. Thanks in advance for your help! ---

Hi Santiago, Please look at the compiler flags that were used in the CMAQ Makefile and add those flags, and the paths to any libraries to your SMOKE Makefile. Liz ---

In addition to what Liz suggests there are precompiled versions of SMOKE as part of the EPA modeling platforms, such as the 2022v1 EMP: [https://gaftp.epa.gov/Air/emismod/2022/v1/smoke\_2022v1\_platform\_2022-2026\_core\_24jan2025.zip](https://gaftp.epa.gov/Air/emismod/2022/v1/smoke_2022v1_platform_2022-2026_core_24jan2025.zip) And as part of the official release: [Release SMOKE v5.2.1 Public Release (September 2025) · CEMPD/SMOKE · GitHub](https://github.com/CEMPD/SMOKE/releases/tag/SMOKEv521_Sep2025) ---

I tried with the precompiled version, but when I try to execute a file, in this case grdmat, I have an issue with : libiomp5.so ubuntu@ip-10-0-6-125:/shared/smoke2022v1/smoke5.1/Linux2\_x86\_64ifort$ ./grdmat ./grdmat: error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory And I can’t install libiomp5.so due to a 403 error: Forbidden. ---

Hi Santiago, The SMOKE executables were likely compiled with the intel compiler, and therefore you may need to install an intel compiler to get the openmp library that is required. I remember that we did install the Intel-one compiler on AWS Parallel Cluster, but there were some issues that @manishsoni may be able to summarize if you need additional details. > **[Get Intel® oneAPI HPC Toolkit](https://www.intel.com/content/www/us/en/developer/tools/oneapi/hpc-toolkit-download.html?packages=hpc-toolkit&hpc-toolkit-os=linux&hpc-toolkit-lin=offline)** > > Select your operating system and distribution channel, and then download your customized installation of this toolkit.
