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.
