Problem "incorrect header format", but only on SUN SunFire V440 server.

Dear GADGET2 users,

I have been following a guide at "
http://astrobites.com/2011/06/11/running-your-first-sph-simulation/" as
well as instructions at "http://www.mpa-garching.mpg.de/gadget/".

I never managed to get Linux up and running OK on the server, tried with
Gentoo but it was always something that did not work. FreeBSD and OpenBSD
on the outher hand was very easy to get up and running.

I have managed to install and build GADGET2 but have problems.

When I start a simulation on my SunFire V440 it looks like this:

------------------------------------------------------------------------------------------------------------
[christer_at_V440 /usr/home/christer/GADGET2/SICtest]$ mpirun -np 4 ./Gadget2
15/SIC_015.param

This is Gadget, version `2.0'.

Running on 4 processors.
application called MPI_Abort(MPI_COMM_WORLD, 890) - process 0
rank 0 in job 1 V440_51366 caused collective abort of all ranks
  exit status of rank 0: killed by signal 9

Allocated 25 MByte communication buffer per processor.

Communication buffer has room for 436906 particles in gravity computation
Communication buffer has room for 204800 particles in density computation
Communication buffer has room for 163840 particles in hydro computation
Communication buffer has room for 163840 particles in domain decomposition


Hubble (internal units) = 3.49333e-06
G (internal units) = 1.23414
UnitMass_in_g = 1.98992e+33
UnitTime_in_s = 1.07793e+12
UnitVelocity_in_cm_per_s = 46385.2
UnitDensity_in_cgs = 1.59194e-17
UnitEnergy_in_cgs = 4.28148e+42

incorrect header format
task 0: endrun called with an error level of 890


[christer_at_V440 /usr/home/christer/GADGET2/SICtest]$
---------------------------------------------------------------------------------------------------------------


Then I copy the Makefile to my Linux PC and also the SICtest/15 folder with
following files:

SIC_015.dat
SIC_015.param-usedvalues
energy.txt
parameters-usedvalues
SIC_015.param
cpu.txt
info.txt
timings.txt

Now everything runs OK, starting with:

[christer_at_Arch SICtest]$ mpirun -np 2 ./Gadget2 15/SIC_015.param

This is Gadget, version `2.0'.

Any idea why it does not work on the SUN server?

All input most appreciated, would be great to get GADGET2 up and running OK.


Thank you.
