Hello,
I have compiled parallel version of siesta-3.2 code with Intel Parallel Studio XE 2016 Cluster Edition. There were not any problems, but every siesta run ended with the next error:
Fatal error in PMPI_Cart_create: Other MPI error, error stack:
PMPI_Cart_create(332).........: MPI_Cart_create(comm=0x84000007, ndims=2, dims=0x7fffe76b6288, periods=0x7fffe76b62a0, reorder=0, comm_cart=0x7fffe76b61e0) failed
MPIR_Cart_create_impl(189)....:
MPIR_Cart_create(115).........:
MPIR_Comm_copy(1070)..........:
MPIR_Get_contextid(543).......:
MPIR_Get_contextid_sparse(608): Too many communicators
displayed for every node (if I am using X nodes, I will see X same messages in output file).
I supposed I have used too many nodes, but decreasing the number of nodes have not solved this problem. Such kind of error appeared when I decided to update release version up to "Update 3" using online installer. People from other forums have given me advise to reinstall MPI env. So I did this, but the problem still occurs. Are there any ideas? My arch.make file is attached.
Thanks a lot for any help!
