I din't check thoroughly the code, but OMPI_ERR_OUT_OF_RESOURCES is not an error. If the registration returns out of resources, the BTL will returns OUT_OF_RESOURCE (as an example via the mca_btl_openib_prepare_src). At the upper level, the PML (in the mca_pml_ob1_send_request_start function) intercept it and insert the request into a pending list. Later on this pending list will be examined and the request for resource re-issued.
Why do we need to trigger a BTL_ERROR for OUT_OF_RESOURCES? george. On Mar 6, 2012, at 09:48 , Jeffrey Squyres wrote: > Mike -- > > I would make this a bit better of an error.
