[mvapich-discuss] error in MPI_Igatherv

[Konz, Jeffrey (SSA Solution Centers)]

Running a Fortran90 code I get this error:



Fatal error in PMPI_Igatherv:

Other MPI error, error stack:

PMPI_Igatherv(324)........:  MPI_Igatherv(sendbuf=0x2aaab8116aa0, sendcount=5184, sendtype

=MPI_REAL, recvbuf=0x2aaab8400010, recvcounts=0x2aaabef75d30, displs=0x2aaabef67c00, recvt

ype=MPI_REAL, root=55, comm=MPI_COMM_WORLD, request=0x2aaabef7c53c)

MPIR_Igatherv_impl(140)...:

MPIR_Igatherv(69).........:

MPID_Sched_recv(599)......:

MPIDU_Sched_add_entry(425): Out of memory



This error occurs when running on 120 nodes (2400 cores). Job runs fine on 90 nodes (1800 cores).

This is with the just released version 2.0-rc2.



Thanks,

-Jeff
