Hi,
I am building ompi v1.6 with knem support and I see that when knem is
enabed from the command line
it is used for all message sizes in SM btl. There is no threshold for when
to start using knem - starting
which message size.
This makes the performance of small messages worse since it also uses
Small messages, i.e. their length is under btl_sm_eager_limit, always use
normal SM. KNEM usage is restricted only for messages over either the eager
size or the btl_sm_knem_dma_min (if KNEM supports DMA).

Hi there,
On a few clusters I am running into an issue where a temporary directory cannot
be created due to the root filesystem being full, causing mpirun to crash.
Would it be possible to change the location where this directory is being
created?

you can specify it with OMPI_TMPDIR in your environment, or "-mca
orte_tmpdir_base " on your cmd line

Wouldn't --tmpdir=... do the same with `mpirun` for way the latter you
mentioned?

Yep - sure would. Lots of ways to specify it :-)

Also should be able to define $TMPDIR with your batch system.
This can be on a much bigger disk.
Hi everyone,
Thanks for the help! As Gus pointed out, I could also have found the
answer from the FAQ but it might have taken me longer to find.
