Subject: [MTT users] [Fwd: MTT -trivial :All tests are not getting passed]

attached mail follows:


HI All,

Today I reran the trivial test on two nodes with (via the --scratch
option) to a NFS share that is accessible to all nodes in hostlist (as
suggested by Ethan).But still no luck.
I have shared
"/root/mtt-svn/samples/installs/nRpF/tests/trivial/test_get__trivial" on
my head node which is accessible to client node.
Then I ran test as "cat samples/developer.ini samples/trivial.ini |
client/mtt --scratch
/root/mtt-svn/samples/installs/nRpF/tests/trivial/test_get__trivial
--verbose - " but still its giving me the same error which I was getting
earlier.

We copied
/root/mtt-svn/samples/installs/nRpF/tests/trivial/test_get__trivial
directory on the client node and changed the trivial.ini as follows:
-- simple_only:tests = &find_executables(".")
++ simple_only:tests =
&find_executables("/root/mtt-svn/samples/installs/nRpF/tests/trivial/test_get__trivial")

and after this we ran the test and we were able to run it successfully.

Does this mean we manually have to either copy the test executables to
client nodes or we have to mount the test executables directory?

Can you please guide us on this to proceed further.

Regards,
Vishal

You need to set your scratch directory (via the --scratch option) to
an NFS share that is accessible to all nodes in your hostlist. MTT
won't copy local files onto each node for you.

Ethan

# Template MTT configuration file for Open MPI developers. The intent

# edit this template for their own needs (e.g., pick compilers to use,
