Hi there,

I am attempting to run a TI calculation. However when I execute the
command, I get the following error

vivek.mtux1:~/Research/amber_MD_runs/ti_beta_g/1g/enzyme/charge-step1$
./ti.run

 Running multisander version of sander Amber11
    Total processors = 4
    Number of groups = 2

Fatal error in PMPI_Bcast: Message truncated, error stack:
PMPI_Bcast(1302)......................: MPI_Bcast(buf=0x7fd88f2bb4b0,
count=47785, MPI_DOUBLE_PRECISION, root=0, comm=0x84000005) failed
MPIR_Bcast(998).......................:
MPIR_Bcast_scatter_ring_allgather(849):
MPIR_Bcast_binomial(157)..............:

received but buffer size is 382280
rank 2 in job 5 mtux1_37500 caused collective abort of all ranks
  exit status of rank 2: killed by signal 9


I am running Amber11 on a Quadcore machine with Ubuntu 10.04

What could be the reason for the job failure?
