Description of problem: There is no mentioned that value of concurrency limit can be a floating point number in Grid User Guide. Moreover there should be some notice that limits are summed from each slot running a job. That means a parallel universe job will count the limits for each slot claimed with the machine_count. E.g. machine_count = 4, concurrency_limits=license:0.25 will give the job cluster a single license. Additional info: see bug 618959
Changes made in revision 0.1-1, build: Red_Hat_Enterprise_MRG-Grid_User_Guide-2.0-web-en-US-0.1-1.el5 Code snippets: <para> Concurrency limits are set when a job is submitted, by specifying the <command>concurrency_limits</command> parameter in the job submit file. The <command>concurrency_limits</command> parameter references a value in the configuration file. The value of the <command>concurrency_limits</command> parameter can be a floating point number and a job submit file can also reference more than one limit. </para> <important> <para> Limits are summed from each slot running a job. For example, a parallel universe job will count the limits for each slot claimed with <command>machine_count</command>. The following example gives the job cluster a single license. </para> <programlisting> machine_count = 4, concurrency_limits=license:0.25 </programlisting> </important>
Chapter 14. Concurrency Limits checked, additional info about concurrency limits added. >>> VERIFIED
