[mpich-discuss] Help with mpich2 1.3a1 on i7-920

[Gaetano Bellanca]

Hi,

I have compiled the new 1.3a1 version of mpich2 on a (single) Intel 
i7-920 (ubuntu 9.10 - Intel Fortran 11.1).
This is a new machine just installed today, and I'm running the first 
tests.
I have successfully compiled my simulator but, launching the simulation 
with:
mpiexec -n 2 -f hosts -bootstrap ssh my_simulator

I have the message:
Assertion failed in file helper_fns.c at line 337: 0
memcpy argument memory ranges overlap, dst_=0x2636cf0 src_=0x2636cf0 len_=4

the host file contains two times the name of the computer.

The same code runs on a different computer with mpich2 1.2.1.
Is it something related to the 1.3a1 version, to the use of hydra, to he 
new architecture I'm using?

Any idea?

Regards.

Gaetano
