STATEMENT OF WORK
Contract Title: Computer Components
Background:
An MCS simulation for each patient diffusion MRI is as large as 100 ~ 200 GB, therefore it is not practical to use cloud-based high-performance computing system, such as Google and Amazon clouds and University of Utah Center for High-Performance Computing (CHPC), which requires at least several hours (or a day) of data transfer. It may take an entire day to generate a MCS data for a specific human data on typical high-end computation system, and the speed of MCS is proportional to the number of CPU core as well as CPU clock speed. As a comparison, it may take longer than an entire week for this MCS on a standard personal computer. For the last 10 years, we have been developing our MCS software using Apple’s Mac Pro, which is the most stable and requires minimal maintenance. We will parallelize two Mac Pros to improve the simulation speed and/or generate MCS data separately and combine/process.
Technical Specifications:
See Below: Appendix A
Additional Information/Requirements:
Computation system for Monte-Carlo Simulation (MCS System): The measured diffusion MRI data will be analyzed and interpreted with respect to the degree of demyelination and axonal loss. The requested computation workstation will be used to numerically simulate the molecular diffusion within the nerve white-matter tissue. This simulated data is used to numerically generate different simulated MRI data for different axonal damage, i.e., damages in myelination and axon. This computation system will need to include CPU(s) with a large number of cores (≥ 24), large memory (≥192 GB), 8 TB or more storage, and large GPU cores for parallel computation of MCS of water diffusion in white-matter tract. This numerical computation system will be dedicated to interpret the measured data and suggest the degree of demyelination and axonal loss for each region-of-interest of patient’s spinal cord lesion. We hope to perform this MCS simulation on the same day of patient MRI measurement and provide our interpretation to physician. We have already developed the MCS simulation and processing software.
Period of Performance:
One year from the date of award, warranty’s to be paid up front and monitored through EER system at the VA.
Ship To:
