High Performance Computational Server for Improved Neuroimaging Analysis

描述（由申请人提供）：此修订提案请求为匹兹堡大学MR研究中心购买计算服务器升级的资金。核磁共振研究中心是一个有15年历史的机构资源，一直致力于为匹兹堡大学和卡内基梅隆大学的生物医学研究界开发和提供最先进的核磁共振数据采集、重建和分析资源。过去，该设施一直从部门资金中支持重大的计算机升级。然而，考虑到目前国内的经济状况，用于资本设备采购的资金有限，我们急需的计算服务器升级已被搁置。这种升级是必要的，因为MRRC使用的几个图像重建和分析软件套件已经很快耗尽了现有服务器提供的计算能力。MRRC支持100多个外部资助的项目（其中80%来自联邦政府），这些项目对计算能力的要求越来越高。拟议的文书旨在满足未来4-5年的这一需求。

DESCRIPTION (provided by applicant): This revised proposal requests funds for purchasing a computing server upgrade for the MR Research Center at the University of Pittsburgh. The MR Research center is a 15-year-old institutional resource that has been committed to develop and provide state of the art resources for MRI data acquisition, reconstruction and analysis to the biomedical research community in the University of Pittsburgh and Carnegie Mellon Universities. The facility has, in the past, continuously supported major computing upgrades from departmental funds. However, given the current economic conditions in the nation, funds for capital equipment purchasing have been limited and the much-needed upgrade for our compute server has been put on hold. This upgrade is needed because the computational power provided by the existing server has quickly been exhausted by several of the image reconstruction and analysis software suites in use at the MRRC. The MRRC supports more than 100 externally funded project (>80% from the federal government) that require an increasingly higher level of computational power. The proposed instrument is designed to meet this need for the next 4-5 years.
