DESCRIPTION (provided by applicant): During two-and-a-half years of funding under NIH GM077138, the EPA's ComTox program, the Dundee computational oncology effort and an increasing number of developmental biologists and tissue engineers have adopted CompuCell3D (CC3D) as a modeling platform. CC3D has become the most widely accepted standard for multi-scale, multi-cell (MSMC) simulations of developmental phenomena and related diseases, with more than 100 trained users, because its open-source combination of the multi-cell capabilities of the Glazier-Graner-Hogeweg (GGH) model, the SBML-compatible subcellular biochemical networks, and continuum and finite-element modeling of tissue-level phenomena, sophisticated user interfaces and scripting capabilities allow rapid construction of useful biomedical models with tunable levels of modeling detail. Motivated by the requests of our increasing number of translational users, this competing renewal will develop a parallel (Graphical Processing Unit (GPU), multi-core and cluster) CC3D2 with fluid-flow support providing up to a hundred-fold increase in speed over CC3D plus the ability to run very large-scale simulations (many cm3, 107-109 cell, whole embryo/organ) with a simple migration path from laptop to diverse parallel architectures (Specific Aim 1). It is significant, because CC3D2 will transform the power of MSMC modeling to allow the development of the detailed, verifiable models required for future clinical-research applications, achieving the goal identified by the NIH-led Interagency Modeling and Analysis Group (IMAG) group: "the development of open source, multi-scale biological simulation environments which run both on single processors and parallel computers and which ..., [permit] users to select the level of simulation detail without further modifying their simulations." It is innovative because it combines the existing expertise of the CC3D development team and the extensive GPU and parallelization experience of the D'Souza group to provide a robust parallel MSMC environment and the first GPU-based implementation of the GGH methodology to allow simulations which were formerly unachievable. As requested by our clinical and biomedical users, CC3D2 will provide an innovative, fast and biologically- intuitive approach to model design, with a novel Cell Behavior Model Specification Language (CBMSL) (Specific Aim 3) and the first sharable graphical model definition available for MSMC (Specific Aim 2). CBMSL will allow researchers to focus on biology rather than computational details and greatly facilitate model cross-validation and sharing, providing an important use-case for future MSMC model-description standardization efforts. Graphical workflow control and enhanced user support and documentation (Specific Aim 4) will further improve CC3D2 usability and increase user adoption.

描述（由申请人提供）：在NIH GM077138，EPA的COMTOX计划，Dundee计算肿瘤学工作以及越来越多的发育生物学家和组织工程师中，采用Compucell3d（CC3D）作为建模平台，在两年半的资金中，EPA的COMTOX计划，邓迪计算肿瘤学工作和越来越多的发展生物学家和组织工程师。 CC3D has become the most widely accepted standard for multi-scale, multi-cell (MSMC) simulations of developmental phenomena and related diseases, with more than 100 trained users, because its open-source combination of the multi-cell capabilities of the Glazier-Graner-Hogeweg (GGH) model, the SBML-compatible subcellular biochemical networks, and continuum and finite-element组织水平现象，复杂的用户界面和脚本功能的建模，可以快速构建具有可调型建模细节的有用生物医学模型。 Motivated by the requests of our increasing number of translational users, this competing renewal will develop a parallel (Graphical Processing Unit (GPU), multi-core and cluster) CC3D2 with fluid-flow support providing up to a hundred-fold increase in speed over CC3D plus the ability to run very large-scale simulations (many cm3, 107-109 cell, whole embryo/organ) with a simple migration path from laptop到不同的平行体系结构（特定目标1）。这很重要，因为CC3D2将改变MSMC建模的功能，以开发未来临床研究应用所需的详细，可验证的模型，实现NIH领导的INTRAGIND INTERAGINCY模型和分析组（IMM）组确定的目标：“开源的模拟环境，这些级别的模拟环境以及平行的计算机的开发，这些级别的模拟环境以及平行的计算机都在...修改他们的模拟。”之所以具有创新性，是因为它结合了CC3D开发团队的现有专业知识和D'Souza集团的广泛的GPU和平行化体验，以提供强大的并行MSMC环境和第一个基于GPU的GGH方法的实施，以允许模拟以前难以理解的模拟。按照我们的临床和生物医学用户的要求，CC3D2将提供一种创新，快速和生物学上直观的模型设计方法，具有新颖的细胞行为模型规范语言（CBMSL）（特定的AIM 3）和第一个可用于MSMC的可共享图形模型定义（特定AIM 2）。 CBMSL将允许研究人员专注于生物学而不是计算细节，并极大地促进了模型的交叉验证和共享，从而为未来的MSMC模型描述标准化工作提供了重要的用例。图形工作流控制和增强的用户支持和文档（特定目标4）将进一步提高CC3D2的可用性并增加用户的采用。
