Hi Andrew,

As a quick solution I would recommend you to try to wrap the proxy (into a shell script) and add architecture recognition/specific logic via something like "uname -m" + check for "k1om" (and execute corresponding binary). So hydra would run the script and the script would select an appropriate proxy binary.

There are several ways but this one should be quick and work fine.

BR, Dmitry

Hello,

I've been trying to use MPICH2 with an application on the Intel Xeon Phi. I have two builds of MPICH2: one host-compatible and one MIC-compatible. So far I have only been able to run either only on the host or only on the MIC; I would ideally like to be able to run on both simultaneously.

I can see what is going wrong: hydra tries to launch a proxy on the MIC which has been compiled for the host and therefore can't be executed. Is there any way to change this default behaviour? I tried changing the launch executable, but it didn't have the effect I wanted.

Thanks for your help, Andrew
