Not able to do parallel run

Hi all,

As seen before on the ML, more and more people are using AMBER on linux
We bought such one, and now we have 4 dual-nodes athlons 1.2Ghz.
I compile amber with mpich- following the procedure described in
README and README.parallel, using Machine.g77_mpich.
The program compiled well.
But i'm not able to go on with the test procedure.
I got losts of errors like :
diffing with run3e_w_300.out
diffing with
cd lj_lj/test; ./run
b run1_b_300
[1] MPI Abort by user Aborting program !
[1] Aborting program!
 Error in setpar: check code, input
p1_28946: p4_error: : 1
bm_list_15437: p4_error: net_recv read: probable EOF on socket: 1

make[1]: *** [test] Interruption
make: *** [CMC] Interruption

I know not all the code is parallelized, but i think the test procedure cope
with it, so i don't know why it is not working ?

I tried with a well-know script for mpi, and i get same errors when i try to
run the script.
So as you can see, i tried to modify P4_GLOBMEMSIZE, but it doesn't worked

Last of all : i patched until the patch 27 (Thanks D. Case, i could use the
command patch, i had to do it manually for those from B. Ross), checked that
i did use the right version.
Again, it compiled well, all my environment variables worked (PATH and
Again, the tests failed.

I have to mention that with mpich-, there are tests provided to check
wheter everything is working or not, and thaty these tests worked.
I hope i provided enough information, and that you could help me :-))

PS : i have been told that because of PME, the amber could not go up to 2
processors, is that true ?
