Cuda Out Of Memory Error

[MHNeobird]

When I have more than a handful of objects, I get a CUDA Out Of Memory Error.

[ERROR]   [SofaCUDA] CUDA error: out of memory returned from cudaMallocHost
  sofa::helper::BackTrace::dump
  mycudaLogError
  mycudaGetMultiProcessorCount
  mycudaMallocHost
  sofa::component::solidmechanics::fem::elastic::TetrahedronFEMForceField<sofa::gpu::cuda::CudaVectorTypes<sofa::type::Vec<3,double>,sofa::type::Vec<3,double>,double> >::peudo_determinant_for_coef
  sofa::component::solidmechanics::fem::elastic::TetrahedronFEMForceField<sofa::gpu::cuda::CudaVectorTypes<sofa::type::Vec<3,double>,sofa::type::Vec<3,double>,double> >::reset
  sofa::component::solidmechanics::fem::elastic::TetrahedronFEMForceField<sofa::gpu::cuda::CudaVectorTypes<sofa::type::Vec<3,double>,sofa::type::Vec<3,double>,double> >::init
  sofa::component::solidmechanics::fem::elastic::TetrahedronFEMForceField<sofa::gpu::cuda::CudaVectorTypes<sofa::type::Vec<3,double>,sofa::type::Vec<3,double>,double> >::peudo_determinant_for_coef
  sofa::component::solidmechanics::fem::elastic::TetrahedronFEMForceField<sofa::gpu::cuda::CudaVectorTypes<sofa::type::Vec<3,float>,sofa::type::Vec<3,float>,float> >::init

I read about compute-sanitizer and when I use it like that
$ compute-sanitizer --tool memcheck runsofa
I get this, what is basically the same error

How can I fix it?

Hi @MHNeobird

Could you please share a scene example for us to better understand the context of the error please ?
