s possible, can the executables of my MPI program
sendable over the wire before running them?
If we exclude GPU or other nonMPI solutions, and cost being a primary
factor, what is progression path from 2boxes to a cloud based solution
(amazon and the like...)

Hello,
I have the following 3 1-socket nodes:
node1: 4GB RAM 2-core: rank 0 rank 1
node2: 4GB RAM 4-core: rank 2 rank 3 rank 4 rank 5
node3: 8GB RAM 4-core: rank 6 rank 7 rank 8 rank 9
I have a model that takes a input and produces a output, and I want to run
this model for N possible combi

in a prorata way, ie f_i/ sum(f_i) => n_i for each core.
sum(n_i) = N
2. A 2nd stage could then be to ensure that no:n_i > m_i/M
which would then involvetaking any excesses (n_i - m_i/M) and
spreading it over the cores.
Or
perhaps both cpufrequencies and maxmem could be considered in 1 go,
but I don't know how to do that?
Thanks

Hi,
openmpi 1.10.3
this call:
mpirun --hostfile ~/.mpihosts -H localhost -np 1 prog1 : -H A.lan -np

works, yet this one:
mpirun --hostfile ~/.mpihosts --app ~/.mpiapp
doesn't. where ~/.mpiapp

oth A.lan and B.lan ?
Yes both A and B have exactly 4 cores each.

Hello,
boost: 1.46.1
openmpi: 1.5.3
winxp : 64bit
For openmpi mailing list users, boost comes with a boost.MPI library which
is a C++-nativized library that wraps around any MPI-1 implementation
available.
Boost libraries can be built with bjam, a tool that is part of a build
system. It comes wit
on winxp, with the following net setup (just localhost, is it on?)
C:\trunk-build-release>ipconfig /all
Windows IP Configuration
Host Name . . . . . . . . . . . . : SOMEHOSTNAME
Primary Dns Suffix . . . . . . . : DOMAIN.SOMECO.COM
Node Type . . . . . . . . . . . . : Hyb
release
and debug version of the libs when built on windows 7 work also for xp?
I would definitely rather use prebuilt openmpi libs as it's easier to change
versions,
thanks,
MM

related to DLLs somehow).
I gather this MPI_Address() function resides in libmpi.lib and libmpid.lib
PS: I didn't have these link errors when I built against the prebuilt win
libraries from the website, what are the CMAke flags for those?
Thanks,
MM
I took off the OMPI_IMPORTS actually and it now compiles correctly. Maybe
those are to be defined if I had built shared lib version of mpi libs.
thanks

but to be able to link against vs2010 Release libs of openmpi, I need them
to be linked against the Release c runtime, so I might as well link against
the debug version of the openmpi libs.
Your help is very appreciated,

Hi Shiqing,
Is the info provided useful to understand what's going on?
Alternatively, is there a way to get the provided binaries for win but off
trunk rather than off 1.5.4 as on the website, because I don't have this
problem when I link against those libs,
Thanks

Hi MM,
Do you really want to build Open MPI by yourself? If you only need the
libraries, probably you may stick to
, I built opnempi static libs (with dll c/c++ runtime)
OMPI_IMPORTS is __not__ defined, that's how I got it to compile

What is the customary solution?
Thanks

not naturally in sync.
Would you suggest to modify the loop to do a MPI_ISend after x iterations
(for the clients) and MPI_IRecv on the root?
Thanks MM
Of course, by this you mean, with the same total number of nodes, for e.g.
64 process on 1 node using shared mem, vs 64 processes spread over 2 nodes
(32 each for e.g.)?

This all sounds quite nightmarish.
