Re: [OMPI users] btl_openib_cpc_include rdmacm questions

2011-05-12 Thread Brock Palen 
I am pretty sure MTL's and BTL's are very different, but just as a note,
This users code (Crash) hangs at MPI_Allreduce() in 

Openib

But runs on:
tcp
psm (an mtl, different hardware)

Putting it out there if it does have any bearing.  Otherwise ignore.

Re: [OMPI users] Windows: MPI_Allreduce() crashes when using MPI_DOUBLE_PRECISION

2011-05-12 Thread Rainer Keller 
Hello Hiral,
in the ompi_info You attached, the fortran size detection did not work 
correctly (on viscluster -- aka that shows the you used the std.-installation 
package):
...
  Fort dbl prec size: 4
...

This most probably does not match Your compiler's setting for DOUBLE 
PRECISION, which probably considers this to be 8.

Does REAL work for You?

Shiqing is currently away, will ask when he returns.

With best regards,
Rainer

Got any ideas here?  Are you able to run this sample program with mpif.h or use 
mpi on Windows?

I should also note that as far as I know I have three codes (CRASH, Namd (some 
cases), and another user code.  That lockup on a collective on OpenIB but run 
with the same library on Gig-e.

So I am not sure it is limited to IMB, or I could be crossing errors, normally 
I would assume unmatched eager recvs for this sort of problem.

Interesting - my prior experience was with real codes, typically "legacy" codes

Re: [OMPI users] Sorry! You were supposed to get help about: But couldn't open help-orterun.txt

2011-05-12 Thread hi 
Hi,

Clarifications:
- I have downloaded pre-build OpenMPI_v1..5.3-x64 from open-mpi.org
- installed it on Window 7
- and then copied OpenMPI_v1..5.3-x64 directory from Windows 7 to
Windows Server 2008 into different directory and also in same
directory

Now on Windows Server 2008, I am observing these errors...

c:\ompi_tests\win64>mpirun mar_f_i_op.exe
[nbld-w08:04820] [[30632,0],0] ORTE_ERROR_LOG: Error in file

As suggested, I tried with following but nothing worked...
- copied to the same directory as it was in previous machine
- executed "mpirun -mca orte_headnode_name HEADNODE_NAME"  and "mpirun
-mca orte_headnode_name MYHOSTNAME"
- set OPENMPI_HOME and other OPAL_* env variables as follow...

set OPENMPI_HOME=C:\MPIs\OpenMPI_v1.5.3-x64
