Re: Unable to build NEURON v8 with CoreNeuron and GPU support

Oh, my previous response might be misleading! I am seeing: CMake Error at external/coreneuron/CMake/OpenAccHelper.cmake:54 (message): GPU support is available via OpenACC using PGI/NVIDIA compilers. Use NVIDIA HPC SDK with -DCMAKE_C_COMPILER=nvc -DCMAKE_CXX_COMPILER=nvc++ What version of CMake you h...

Re: OpenMP based parallelism in NEURON

This was answered on Github - NEURON uses PThead for thread parallelism. (CoreNEURON uses OpenMP)

Re: NEURON on ARM M1, Big Sur and Rosetta

Hello watersun, We have recently fixed the issue with ARM M1 installation. We don't have a binary installer yet but should be available in coming week or two. In case you are familiar with building from source and CMake, you can clone latest master of neuron repository and build as documented in: ht...

Re: Gui Freezing

Hello LauraD, watersun, Could you tell us which version of NEURON you are using? You can try with the latest version, see instruction here: https://github.com/neuronsimulator/nrn/blob/master/INSTALL.md#installing-binary-distribution (Make sure to remove existing / old installation if any) We haven't...

Re: NEURON on ARM M1, Big Sur and Rosetta

Hello @watersun,

We don't have access to M1 system yet. But one of our colleague tested NEURON python wheel under Rosetta and it worked fine.

If you try something and see any issues, please let us know!

Thanks!

Re: How to build network model for coreNeuron 

The error is "call to cudaGetSymbolAddress returned error 13:" Above CUDA error code means "One or more of the parameters passed to the API call is not within an acceptable range of values." I am wondering if there is some mix of CUDA versions and PGI compiler (if you have multi...
