Globus Toolkit的pre-Web Services GRAM服务（“GRAM2”）已在世界各地的网格上广泛部署多年。最近的工作产生了一个新的、基于Web服务的GRAM服务（“GRAM4”）。我们描述并比较了Globus Toolkit版本4 （GT4）中包含的GRAM2和GRAM4作业执行服务的功能和性能。在许多方面，GRAM4在功能和可伸缩性方面都比GRAM2有了显著的改进。GRAM4在许多并发提交的情况下更快，但在顺序提交和涉及文件暂存的情况下速度较慢。（针对后一种情况的优化正在进行中。）在考虑从GRAM2升级到GRAM4，以及将GRAM与其他作业执行服务进行比较时，这些信息应该很有用。
The Globus Toolkit's pre-Web Services GRAM service ("GRAM2") has been widely deployed on grids around the world for many years. Recent work has produced a new, Web Services-based GRAM service ("GRAM4"). We describe and compare the functionality and per- formance of the GRAM2 and GRAM4 job execution services included in Globus Toolkit version 4 (GT4). GRAM4 provides significant improve- ments in functionality and scalability over GRAM2 in many areas. GRAM4 is faster in the case of many concurrent submissions, but slower for sequential submissions and when file staging is involved. (Optimizations to address the latter cases are in progress.) This information should be useful when considering an upgrade from GRAM2 to GRAM4, and when comparing GRAM against other job execution services.
