[Qemu-devel] QEMU redesigned for MPI (Message Passing Interface)

[Victor Vasilchenko]

Good day,

I've got an idea in my head and can't get rid of it - neither can I find any solution on web.

The idea is to use the Virtualization Software with the purpose OPPOSITE to it's natural way.

The practical example below will explain it completely:

1) we take 4 common modern computers - CoreQuad + 8 GB Memory.
2) we assemble a standard Linux cluster with 16 cores and 32G memory.
3) and now - we run the only one virtual guest system, but give it ALL available resources.

The result:
A Virtual PC running on 15 cores and 31Gb of memory (-1 for host OS and VM software).

Any modern OS installed inside this Virtual PC will utilize all resources in normal way :
1) the video encoding software will use 15 threads for transcoding
2) the 3D studios (Maya/Max) will use 15 threads and all 31GB memory
3) make -j 15
4) etc.

There is no need to redesign (with MPI MPICH/LAM support) a standard, currently used programs - they will just work as one would run them on standard CoreQuad system,
but almost 4 times faster (15cores).

Looks great so far, doesn't it?

The only BIG question - what virtualization software can support MPI to effectively work on cluster ?

I am asking this question to QEMU team cause I believe QEMU can be the one.
If you have any ideas or experiments or information - please share with me.

Kind Regards,
Victor.
