Hello, everyone , what's the matter of this problem!


---------------------------------------

Fatal error in PMPI_Allgatherv: Internal MPI error!, error
stack:
PMPI_Allgatherv(1089).....: MPI_Allgatherv(sbuf=0x101fd90, scount=1,
dt
ype=USER<contig>, rbuf=0x1010600, rcounts=0x100bb30,
displs=0x100f5c0,
dtype=0x4c000829, MPI_COMM_WORLD)
failed

MPIR_Allgatherv_impl(922).:
MPIR_Allgatherv(884)......:

MPIR_Allgatherv_intra(634):

MPIR_Localcopy(357).......: memcpy arguments alias each other,
dst=0x10
25000 src=0x101fd90 len=42256
------------------------------
And why in the following , the MPI_gatherv is correct while MPI_allgatherv
is notl. The else sub statement works well and the former one do not work!

------
 29 if ( .true. )
then

 30    call MPI_allgatherv( val, sz*2, MPI_REAL8,
&

 31    res, cnt, strd, MPI_REAL8, MPI_comm_world, ier
)

 32
else

 33    call MPI_gatherv( val, sz*2, MPI_REAL8,
&

 34    res, cnt, strd, MPI_REAL8, 0, MPI_comm_world, ier
)

 35    call MPI_Bcast( res, x_sz*2, MPI_REAL8,0,MPI_Comm_world, ier
)
 36 end if
