Hi, All,
A couple of applications that I'm using -- VASP and Charmm -- end up
"stuck" (for lack of a better word) during a waitall call after some
non-blocking send/recv action. This only happens when utilizing the
openib btl. I've followed a couple of bugs where this seemed to happen
in some pr

I see this going through, but would it be possible to change the size of
the _count field in ompi_status_public_t now so that this bug can be
fixed without ABI br

Depending on the datatype and its order in memory, the "Block,*" and "*,Block"
(which we used to call "slabs" in 3D) may be implemented by a simple
scatter/gather call in MPI. The "Block,Block" distribution is a little more
complex, but if you take advantage of MPI's derived datatypes, you may
Hey Bill,
I took a look at the documentation for MPI_Scatter(), but I noticed that you
need buffers to use it. My supervisor wasn't really happy with using
buffers, and for that reason the code that I am writing is only using
blocking routines, which will make my life a tad bit harder due to the f
We're having some problem replicating this once my patches are applied. Can you
send us your configure cmd? Just the output from "head config.log" will do for
now.
Thanks!

I just built openmpi/1.4.2 with the pgi compilers against psm and verbs (we
have both sets of gear)
I noticed that after building, that psm nor any other mtl (psm is the only one
we expect) appears in ompi_info
Our configure:
./configure --prefix=/home/software/rhel5/openmpi-1.4.2/pgi-9.0

Mmm. Good point.
George?

The MPI Standard (in my opinion) should have avoided the word "buffer". To
me, a "buffer" is something you set aside as scratch space between the
application data structures and the communication calls.
In MPI, the communication is done directly from/to the application's data
structures and th

You're probably looking for the runtime option -mca yield_when_idle 1.
This will slightly increase latency, but allows other threads to run
without competi

Hi Jed,
Thanks for the reply and suggestion. I tried adding -mca
yield_when_idle 1 (and later mpi_yield_when_idle 1 which is what
ompi_info reports the variable as) but it seems to have had 0 effect.
My master goes into fftw planning routines for a minute or so (I see the
threads being created),

I'm running linux (slackware 12.2), openmpi 1.4.2 and fftw3 3.2.4.
As to the planner always running in parallel, I suspect it isn't. It's
trying to optimize the split up the fft computation between different
codelets and different numbers of threads (including none). It tries
something and meas

Hi all:
I'm using openmpi-1.4.2. I need to run pvserver(a mpi program of

I try tu run pvserver (The paraview server) in a cluster, using the next

Sorry - the cmd line option you are looking for was changed to avoid confusion.
It is now --leave-session-attached

Thank you very much RALPH I've tried and it worked perfectly.
I owe you one ;) ;)
Now i have one more question:
How could i reply to a Question. I need to login into openmpi mailing list
and then reply? Because I send a new mail.
