Hello all,

I'm trying to run an MPI program but keep getting error messages before
reaching
the main statement of the MPI program.

1) On a Fujitsu AP100 I got the following messagss:

------------------------------------------------------------
 Welcome to the IFPC Arbitrator(tm) scheduling system.
Waiting for the all clear to load caren.
Proccess starting.

### ERROR [cid=0 tid=0] : sig=11 code=0x4 addr=0x0000004c ###
Segmentation violation : access exceeded protections


### ERROR [cid=1 tid=0] : sig=11 code=0x4 addr=0x0000004c ###
Segmentation violation : access exceeded protections

-----------------------------------------------------------

2) On a Meiko CS (with T800) I got the following messages: 

-----------------------------------------------------------
[chimp`chp{2}`process_farm.t800] register dump at iptr 0x8000120d
(0x20d) wptr 0x80041679 (0x3d25) (address error)

[chimp`chp{0}] Address Error
-----------------------------------------------------------


Any ideas about what might be causing this problem. I've manged to run
other MPI
programs on both machines.

Please reply by e-mail to hamdan@cee.hw.ac.uk

Thanks in advance.
