[Users] error after activating IllinoisGRMHD and VolumeIntegrals_GRMHD

Dear Zach,
Becasue if I only activate VolumeIntegrals_GRMHD but not IllinoisGRMHD , there will be following error in the .out file:

Error: Implementation 'ILLINOISGRMHD' not activated.
       This implementation is required by activated thorn(s):
           VolumeIntegrals_GRMHD (implementing VolumeIntegrals_GRMHD)
       This implementation is provided by compiled thorn(s):
       Add a thorn providing this implementation to the ActiveThorns parameter.
Activation failed - 1 errors in activation sequence

It seems it is required to activate IllinoisGRMHD  in order to use VolumeIntegrals_GRMHD.

Hi Chia-Hui,

Is there a reason you are using IllinoisGRMHD for this particular example? The example was written for GRHydro.

Dear whom it may concern,

I tried to solve the tracking problem of unequal mass binary neutron (http://einsteintoolkit.org/gallery/bns/index.html ) star by using the thorn WVUThorns_Diagnostics / VolumeIntegrals_GRMHD . Therefore I activate both IllinoisGRMHD and VolumeIntegrals_GRMHD. However I met the error which showed in both .err file and .out file.

In .err file:
Thu Jul 12 08:03:04 2018: [unset]:_pmi_alps_init:alps_get_placement_info returned with error -1
Thu Jul 12 08:03:04 2018: [unset]:_pmi_init:_pmi_alps_init returned -1

In .out file:

I am not sure what these error exactly mean and how to solve it.
