parallel quickstep with CUDA enabled doesn't solve contact correct #1474

Open osrf-migration opened 9 years ago

osrf-migration commented 9 years ago

Original report (archived issue) by Ying Lu (Bitbucket: rosebudflyaway).

with CUDA enabled, tested parallel quickstep solvers with a small number of bodies, which in theory should have the same results with serial quickstep. But they have weird behaviors of jumping and tilting after stay on the ground for one time step or so. Results could be reproduced with this repo quickstpe_cuda. quickstep_cuda.world is used to test.

Make sure CUDA toolkit is installed.

Update: c_v_max, erp terms, precon terms are left out in quickstep, check here.
