[mpich-discuss] Hydra round robin questions

[Saurabh T]

Hi,
I made a hosts file like this:
name0:2 binding=rr
name1:4 binding=rr
name3:1 binding=rr

to utilize various machines with various number of cpus at our site. However when I run mpich, the ranks are assigned: [name0,name0,name1,name1,name1,name1,name3, {repeat}]. I want them to be assigned: [name0,name1,name3,name0,name1,name1,name1, {repeat}]. How do I do this?

Second, how do I always make rank 0 start on the machine where mpirun was invoked?

Thank you.
