[mvapich-discuss] MVAPICH2-0.9.8 internal errors

[wei huang]

Hi,

Thanks for letting us know this problem.

We will try to reproduce the problem on our cluster. To help us on looking
into this problem, would you please let us know the following:

1) The exact CFLAGS you are using when configuring mvapich2 (are you using
default scripts provided by us?)
2) Any runtime environment variables you have setup up?
3) On how many nodes do you run the test?

Thanks.

Regards,
Wei Huang
