This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.We are applying parallel computing techniques to the spectral simulations and fittings of slow motional ESR data. We are planning on installing a new cluster of 16-18 nodes to implement the parallel computing tasks. This will meet the increasing computational challenges we are facing when our slowly relaxing local structure (SRLS) model is applied to more complex biological systems, such as anisotropic lipid membranes and protein either/both diffusion tilts or/and cage tilts. It will also allow us to include more dynamic modes to better approximate the rotational dynamics in these systems. We are now testing our parallelized codes on a number of existing clusters on campus, which will help us to decide what kind of cluster best meets our special needs, contingent on the availability of suitable funding sources.
