Mathematical modelling has become a standard technique to improve our understanding of complex biological systems. As models become larger and more complex, simulations and analyses require increasing amounts of computational power. Clusters of computers in a high-throughput computing environment can help to provide the resources required for computationally expensive model analysis. However, exploiting such a system can be difficult for users without the necessary expertise.
We present Condor-COPASI, a server-based software tool that integrates COPASI, a biological pathway simulation tool, with Condor, a high-throughput computing environment. Condor-COPASI provides a web-based interface, which makes it extremely easy for a user to run a number of model simulation and analysis tasks in parallel. Tasks are transparently split into smaller parts, and submitted for execution on a Condor pool. Result output is presented to the user in a number of formats, including tables and interactive graphical displays.
Condor-COPASI can effectively use a Condor high-throughput computing environment to provide significant gains in performance for a number of model simulation and analysis tasks. Condor-COPASI is free, open source software, released under the Artistic License 2.0, and is suitable for use by any institution with access to a Condor pool. Source code is freely available for download at http://code.google.com/p/condor-copasi/, along with full instructions on deployment and usage.
数学建模已成为增进我们对复杂生物系统理解的一种标准技术。随着模型变得越来越大且越来越复杂,模拟和分析需要越来越多的计算能力。高通量计算环境中的计算机集群有助于提供计算成本高昂的模型分析所需的资源。然而,对于没有必要专业知识的用户来说,利用这样一个系统可能很困难。
我们展示了Condor-COPASI,这是一种基于服务器的软件工具,它将生物途径模拟工具COPASI与高通量计算环境Condor集成在一起。Condor-COPASI提供了一个基于网络的界面,这使得用户能够极其轻松地并行运行多个模型模拟和分析任务。任务被透明地拆分为更小的部分,并提交到Condor池中执行。结果输出以多种格式呈现给用户,包括表格和交互式图形显示。
Condor-COPASI能够有效地利用Condor高通量计算环境,为多个模型模拟和分析任务显著提高性能。Condor-COPASI是免费的开源软件,根据艺术许可2.0发布,适用于任何能够访问Condor池的机构。源代码可在http://code.google.com/p/condor-copasi/上免费下载,同时还提供了关于部署和使用的完整说明。
