[mpich-discuss] specifying hosts with hydra in the configfile

[Camilo Rostoker]

Hi,

How can I specify which host a given executable should run on?

Before migrating to hydra, I had an configfile which had lines like the
following:

-n 5 -host node01 executable1
-n 4 -host node02 executable2
-n 2 -host node03 executable3

this let me specify which hosts each executable should run on.

If I use this configfile format with hydra, I get the following error

"duplicate host file or host list setting"

I'm using the latest build of hydra (1.3.b1)

Thanks in advance for any help on this matter.

Cheers,
Camilo
