[mvapich-discuss] "CMA is not available. Set MV2_SMP_USE_CMA=0" error w/MVAPICH2 2.2 after kernel update?

[Ryan Novosielski]

Hi there,

Our site has recently upgraded our kernel from 3.10.0-229.20.1 to 3.10.0-693.11.1 and suddenly I’ve started seeing "CMA is not available. Set MV2_SMP_USE_CMA=0 to disable CMA.” with our copy of MVAPICH2 2.2 that we’ve been using for some time. This doesn’t make a lot of sense to me, given that all versions of 3.10.x are newer than the 3.2 that should be required for this feature.

Is there any troubleshooting advice?

Thanks!
