Running Abaqus on HPC cluster

1. Issues with 6.14-1 version

I ran the 6.14-1 version on an HPC cluster, which only supports Linux platform. I would prepare the input file locally using Abaqus 2024 and then send the job for solving on the cluster. There are only few models solved. A simple baseline model showed an error "Too large to run with Abaqus" with 2 nodes and 64 tasks. However, it would solve in 20 min on my local PC (8 cores CPU, Intel Xeon E5-2367 v3). I appreciate that the 2024 input file might not be fully configured for the 6.14-1 version, but I'd expect different errors, such as some reference words are not recognisable. I suspect there have been a lot of solver updates since that version. Also, I can't really find a good way to modify the 2024 input file back to the 6.14-1 version. Are there any easy ways of doing this and are the solvers excessively updated between the versions?

 

2. Issues with 2024 version

I'm also trying to run abaqus 2024 on the cluster. Installation and licensing have been solved. But I keep getting a new error that I haven't encoutered with 6.14-1 before: Abaqus Error: The number of cpus (64) exceeds the number of cpus available (36).

This error would persist if I request 32 cpus and only 30 is available. It's confusing because with 6.14-1, it would wait until the requested number of cpus available and then run the job through SLURM scheduler. The 2024 job is configured the same way, and the nodes have been allocated successfully.
