[petsc-users] About hardware limitation/recommendation for PETSc (new user)

[Tianchi Li]

Hello,



I’m planning to parallelize my C++ simulation code with PETSc.



And I wish to buy a local workstation to perform the parallel code
development and later productive runs.



Before purchasing the workstation, I wish to know if there is any
limitation or recommendation for PETSc implementation on the hardware side ?



For example, is there any hardware limitation about the MPI or GPU
parallelism ? (e.g. Nvidia or AMD graphics cards, Intel or AMD CPUs)



Concerning cost-effectiveness, does a hybrid CPU-GPU machine have more
advantages than an all-CPU one ? (if using GPU acceleration)



Thank you so much in advance.


I appreciate any advice that you provide.
