[MITgcm-support] mpi problem after cvs update

[m. r. schaferkotter]

all;
i did cvs update yesterday (jan 22), and now i/m getting these error  
messages after building and attempting to run my (moments earlier  
successful) job.

schaferk:sapphire01% more r.001.err
aborting job:
Fatal error in MPI_Allreduce: Invalid MPI_Op, error stack:
MPI_Allreduce(714).......: MPI_Allreduce(sbuf=0x7fffffffb28c,  
rbuf=0x7fffffffb2ec, count=1, dtype=0x4c00081b, MPI_SUM, M
PI_COMM_WORLD) failed
MPIR_SUM_check_dtype(388): MPI_Op MPI_SUM operation not defined for  
this datatype
aborting job:
Fatal error in MPI_Allreduce: Invalid MPI_Op, error stack:
MPI_Allreduce(714).......: MPI_Allreduce(sbuf=0x7fffffffb28c,  
rbuf=0x7fffffffb2ec, count=1, dtype=0x4c00081b, MPI_SUM, M
PI_COMM_WORLD) failed


fortunately, i moved aside the old executable and the job runs with  
that.


what/s up with this?
