Howdy,

When using the Mumps system, I am receiving the following error:

MPI_Channel::recvVector() - incorrect number of entries for Vector received: -32766 expected: 24

The call stack leading up to this failure is:

Code: Select all

	OpenSeesSP.exe!MPI_Channel::recvVector(int dbTag, int commitTag, Vector & theVector, ChannelAddress * theAddress) Line 340	C++

Error occurs when the MumpsParallelSOE is receiving the *vectX from each channel. A quick try with SuperLU shows the same issue.

Error occurs using both IMPI and OpenMpi.

Is there anything obvious that may be the issue here? I can provide more details if necessary.

Thank you

Can you spit out the size and values in vectX before the call the recvVector in MumpsParallelSOE line 353ish?

I believe it is related to the NormUnbalance convergence test. If I change to NormDispIncr, the issue goes away.

I can confirm this as well using the lastest OpenSeesSP code. I was having this same error using NormUnbalance. When changing to NormDispIncr, it went away. Any thoughts/updates on this?
