:orphan: # PetscMallocSetCUDAHost Set `PetscMalloc()` to use `CUDAHostMalloc()` Switch the current malloc and free routines to the CUDA malloc and free routines ## Synopsis ``` #include "petscsys.h" PetscErrorCode PetscMallocSetCUDAHost(void) ``` Not Collective ## Note This provides a way to use the CUDA malloc and free routines temporarily. One can switch back to the previous choice by calling `PetscMallocResetCUDAHost()`. ## See Also `PetscCUDAHostMalloc()`, `PetscMallocResetCUDAHost()`, `PetscMallocSetHIPHost()` ## Level developer ## Location src/sys/memory/cuda/mcudahost.cu --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/src/sys/memory/cuda/mcudahost.cu) [Index of all Sys routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
