[mpich-discuss] cpu binding with 1.5 hydra

I see that all 1.4.1 binding options have changed. Please confirm though.

CPU based options:

    sockets -- allocate processes to one socket at a time (allocating all processing units on the socket to each process)
    cores -- allocate processes to one core at a time (allocating all processing units on the core to each process)
    rr:sockets -- allocate processes to one socket at a time (rotating between the processing units on each socket)
    rr:cores -- allocate processes to one core at a time (rotating between the processing units on each core) 

Cache based options:

    l1 -- allocate processes to one L1 cache domain at a time (allocating all processing units on the cache domain to each process)
    l2 -- allocate processes to one L2 cache domain at a time (allocating all processing units on the cache domain to each process)
    l3 -- allocate processes to one L3 cache domain at a time (allocating all processing units on the cache domain to each process)
    rr:l1 -- allocate processes to one L1 cache domain at a time (rotating between the processing units on each cache domain)
    rr:l2 -- allocate processes to one L2 cache domain at a time (rotating between the processing units on each cache domain)
    rr:l3 -- allocate processes to one L3 cache domain at a time (rotating between the processing units on each cache domain)

Rohit

Are cpu:sockets and cpu:cores binding deprecated in 1.5 release? It used to work with 1.4.1.
