[mpich-discuss] Dual core problem

[huraj at ucm.sk]

When I run the MPI program the outputs are different. Sometimes the output
is correct, sometimes I obtain error message and sometimes job aborting.
See the outputs:

[01:4088]......ERROR:result command received but the wait_list is empty.
[01:4088]....ERROR:unable to handle the command: "cmd=result src=1 dest=1
tag=5 cmd_tag=2 cmd_orig=dbput ctx_key=1 result=DBS_SUCCESS "
[01:4088]...ERROR:sock_op_close returned while unknown context is in
state: SMPD_IDLE
[01:2392]......ERROR:result command received but the wait_list is empty.
[01:2392]....ERROR:unable to handle the command: "cmd=result src=1 dest=1
tag=9 cmd_tag=2 cmd_orig=dbput ctx_key=2 result=DBS_SUCCESS "
[01:2392]...ERROR:sock_op_close returned while unknown context is in
state: SMPD_IDLE

or
[01:1452]......ERROR:result command received but the wait_list is empty.
[01:1452]....ERROR:unable to handle the command: "cmd=result src=1 dest=1
tag=4 cmd_tag=1 cmd_orig=dbget ctx_key=0 result=DBS_FAIL "

job aborted:
rank: node: exit code[: error message]
0: localhost: 123
1: localhost: 123
2: localhost: -1073741819: process 2 exited without calling finalize

or correctly
Received: Hello, world from process 1!
Received: Hello, world from process 2!
MASTER: All Done!

The program code is correct; it runs well on different PC.

I am afraid the problem is in my notebook. The notebook is Intel Core2 Duo
CPU.
I tried to change the setting ‘hosts’ in wmpiconfig (to
localhost:2) for dual core but nothing has changed.
I need it only for local using.

Thanks

Ladislav
