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. 

Thanks.
