Description
Fix a GPU memory leak in
Forces<double, base_device::DEVICE_GPU>::deriv_drhoc_sccfunction.Changes
delmem_var_op()call to properly free GPU memory (aux_d,gx_arr_d,drhocg_d) inside the GPU-specific conditional block.Issue
The GPU memory (
aux_d,gx_arr_d,drhocg_d) was allocated inside anif (this->device == base_device::GpuDevice)block but never freed, causing memory leaks.Testing
Verified using
compute-sanitizerthat the memory leak is resolved.
