[mvapich-discuss] Problem with MPI_Init

[Schwind Michael]

Hello,

first lets say thank you for your great work
on mvapich. 

Now my problem:

My program hangs  in MPI_Init, when I start it.


The problem seems to be that the thread 
waits to lock a mutex. 

The mutex was set in MPI_Init through
MPID_CS_ENTER() on line 89 in init.c.

The thread calls the macro  MPID_CS_ENTER()
a second time in the function MPI_Comm_rank
some time later in the function MPI_Init:

if (split_comm == 1){
       int my_id, size;
       MPI_Comm_rank(MPI_COMM_WORLD, &my_id);

My distribution is debian testing on amd64.
I use openmpi 1.0 compiled with gcc 4.1.2. 


Whats wrong with my setup.

Thanks

Michael
