Thanks again. I don't think the I/O bandwidth is issue. Because once I run the parallel with all time the run happening I am seeing the CPU usage as as 99% . So if that is an issue with I/O then the all process wont run at 99% right ?

When I forked out different process. Each will have the same priority right and I/O is the shared resource which should be equal to all process. that's what I am confussed

I am using top to determine the speed. is there is any utility which give more insights ?

NAME
voxbo - general information about the VoxBo toolbox DESCRIPTION
VoxBo is a suite of tools for brain image analysis, especially fMRI analysis and lesion-behavior mapping. VoxBo includes over 100 tools, including many for general-purpose image munging (e.g., vbim(1)), many that implement specific statistical procedures (e.g., vbtmap(1)), and some that would likely be just as useful for non-imaging applications (vbbatch(1)). VoxBo has supported cluster parallel processing since 1998. Although cluster installation is a little tricky, it's worth the effort if you'd like to speed up your analyses by an order of magnitude or two. As of 2010, VoxBo also supports desktop parallel processing on multi-core systems. We do not yet support GPU parallel processing. All VoxBo tools support a common set of file formats. See voxbo-fileformats(7) for more information. AVAILABILITY
Pre-built VoxBo binaries are available for Linux, OSX, and Cygwin, and via the NeuroDebian project (neuro.debian.net) for Debian deriva- tives. CAVEATS
