具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
如图1所示，一种资源管理方法，包括以下步骤：
步骤S110，确定任务群组内的任务及与任务群组内的每个任务对应的预设的任务时间。
具体的，预设的任务时间为预设的任务群组内的任务在单位时间内可获得的资源使用时间上限，即任务群组内的每一项任务在单位时间内的运行时间不超过与之对应的任务时间，在本实施方式中，可设定任务群组内所有任务对应的预设的任务时间是相同的。例如，假设单位时间为2T，任务时间为L，L可为T/2、T/4等。每2T单位时间内，任务群组内的每一项任务最多只能使用L时间的资源。T可以为10s(秒)、15s、20s等时间较短的数值。资源可为CPU、GPU、内存等。可以理解地，任务群组内的每个任务对应的预设的任务时间可以根据实际需要进行设定，不一定完全相同。
在一个实施例中，在步骤确定任务群组内的任务及与任务群组内的每个任务对应的预设的任务时间之前，还包括：建立任务群组，并根据预定的规则将特定的任务添加入该任务群组。
具体的，建立任务群组对任务进行管理，只有在该任务群组中的任务，才受任务群组的资源使用时间额度的限制。任务群组中的任务可为不需与用户进行交互的后台任务，例如邮件服务、讯息传递、自动保存等后台任务。将某些任务添加入任务群组中并进行资源使用限制，既可保证任务群组内的任务正常执行，也可避免任务群组内的任务无限制地与任务群组外 的其它任务抢占资源，造成资源浪费。可以理解地，还可以根据需要设定其它的规则，然后将符合规则的特定任务添加到任务群组中。
步骤S120，判断任务群组内所有任务对应的预设的任务时间之和是否小于预设的时间阈值，若是，则执行步骤S130，若否，则执行步骤S140。
具体的，时间阈值为预先设定的任务群组在每单位时间内的资源使用时间上限。单位时间、时间阈值、任务时间需可根据需求进行设定，三者的关系为单位时间大于时间阈值，时间阈值大于任务时间。比较任务群组内所有任务对应的预设的任务时间之和与时间阈值的大小，若任务群组内所有任务对应的预设的任务时间之和小于时间阈值，则确定任务群组在单位时间内的资源使用时间额度为任务群组内所有任务对应的预设的任务时间之和，若任务群组内所有任务对应的预设的任务时间之和不小于时间阈值，则确定任务群组在单位时间内的资源使用时间额度为时间阈值。如图2所示，包括任务群组外的任务20及任务群组10。其中，设定任务群组10内任务D、E对应的预设的任务时间均为L，时间阈值为T，在第一个2T单位时间内，任务群组10内的任务D、E对应的预设的任务时间之和为2L，小于预设的时间阈值T，则任务群组10的资源使用时间额度为2L。在第二个2T单位时间内，任务群组10包括任务D、E、F，设定任务群组10内任务D、E、F对应的预设的任务时间均为L，则任务群组10内的任务D、E、F对应的预设的任务时间之和为3L，大于时间阈值T，则任务群组10的资源使用时间额度为T。在单位时间内，任务群组内的所有任务所允许的运行时间之和小于或等于任务群组的资源使用时间额度。
步骤S130，确定任务群组的资源使用时间额度为任务群组内所有任务对应的预设的任务时间之和。
具体的，通过比较任务群组内所有任务对应的预设的任务时间之和和时间阈值来确定任务群组的资源使用时间额度，可避免当任务群组内的任 务数量太少时造成的资源浪费，将任务群组中的每个任务所获得的资源使用时间控制在合理范围内。例如，设定单位时间为2T，时间阈值为T，任务群组中只有一个任务，且该任务对应的预设的任务时间为T/4，若不通过比较任务群组内所有任务对应的预设的任务时间之和和时间阈值来确定任务群组的资源使用时间额度，则该任务在2T单位时间内可使用T时间的资源，此时可能会造成资源使用效率低等问题，而通过比较再确定任务群组的资源使用时间额度后，该任务在2T单位时间内最多只可使用T/4时间的资源，能提高资源的使用效率。
步骤S140，确定任务群组的资源使用时间额度为该时间阈值。
步骤S150，确定任务群组的各个任务在单位时间内所允许的运行时间。
具体的，将时间划分为连续的多个单位时间进行监测，任务群组的任务只在单位时间中的部分时段内才拥有资源使用权，即任务群组中的每个任务仅在与其对应的部分时段被运行，该部分时段的时长等于前述确定的所允许的运行时间。任务群组内的所有任务在单位时间内所允许的运行时间之和小于或等于前述确定的任务群组的资源使用时间额度。
步骤S160，在单位时间内，当任务群组的各个任务在对应的运行时段之外时，使任务群组的各个任务分别进入等待状态。
具体的，在单位时间内，只有在任务群组的各个任务对应的运行时段内时，才执行该任务，该运行时段的时长等于该任务在单位时间内所允许的运行时间。图3为一个实施例中任务群组的任务执行时的示意图，如图3所示，在第二个2T单位时间内时，假定任务群组10的资源使用时间额度为2L，任务E、F所允许的运行时间均为2L/3，在任务E、F各自对应的运行时段内，执行该任务，当在各自对应的运行时段之外时，任务E、F则分别处于等待状态。等待状态指该任务不会使用任何资源。任务E、F所允许的运行时间之和小于任务群组10的资源使用时间额度2L。在第三个2T单位时间 内，假定任务群组10的资源使用时间额度为T，任务E、F、G所允许的运行时间均为T/3，在任务E、F、G各自对应的运行时段内，执行该任务，当在各自对应的运行时段之外时，任务E、F、G则分别处于等待状态。任务E、F、G所允许的运行时间之和等于任务群组10的资源使用时间额度T。只需保证在单位时间内任务群组内所有的任务所允许的运行时间之和小于或等于任务群组的资源使用时间额度即可，而任务群组内的各个任务在单位时间的什么时段内运行则由操作系统的任务调度器的算法决定。在其它实施例中，任务群组内的任务在单位时间内，可先进入等待状态，再进行执行，例如2T单位时间内，任务群组内的所有任务先进入等待状态，T时间后，再按照任务群组内的各个任务所允许的运行时间执行各个任务，可以理解，其本质上与图3的资源管理方法是一致的。
上述资源管理方法，通过比较该任务群组内所有任务对应的预设的任务时间之和及预设的时间阈值大小，以此决定群组的资源使用时间额度，能够根据群组内的每个任务对应的预设的任务时间动态控制群组内的任务所能使用的资源，确保群组内每个任务所获得的资源使用时间在合理范围内，提高资源使用效率，节约资源。此外，群组内的各个任务在单位时间内只在其对应的运行时段内运行，既能保证群组内的工作完成，又能减少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
如图4所示，在一个实施例中，步骤确定任务群组的各个任务在单位时间内所允许的运行时间，具体包括：
步骤S410，获取任务群组内的任务的优先级。
具体的，在单位时间内，任务群组内的任务可最多获得任务群组的资源使用时间额度的资源。若此时，无任务群组外的任务在执行，任务群组内的任务无需与任务群组外的其它任务竞争资源，任务群组内的任务所允许的运行时间可根据任务的优先级高低并按照预定的算法进行确定。通常， 任务群组内优先级高的任务比优先级低的任务会获得更多的所允许的运行时间。
步骤S420，判断任务群组内的任务的优先级是否相同，若任务群组内的任务的优先级相同且没有任务群组外的任务正在执行，则执行步骤S430，若否，则执行步骤S440。
具体的，若任务群组内的任务的优先级相同，则任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组内的任务数量，若任务群组内的任务的优先级不同，则根据任务的优先级高低并按照预定的算法确定任务群组内各个任务在单位时间内所允许的运行时间。
步骤S430，确定任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组内的任务数量。
具体的，例如，如图5所示，在第一个2T单位时间内，无任务群组外的任务正在执行，假定任务群组10的资源使用时间额度为2L，任务群组10内包括任务D和任务E，任务数量为2，则任务D和任务E各分得L的资源使用时间；在第二个2T单位时间内，无任务群组外的任务正在执行，假定任务群组的资源使用时间额度为T，任务群组10内包括任务D、E、F，则任务D、任务E和任务F各分得T/3的资源使用时间。在其它的实施例中，若还有任务群组外的任务正在执行，则任务群组内的任务所允许的运行时间将小于本实施例中获得的资源使用时间。
步骤S440，基于任务群组内的任务的优先级高低并按照预定的算法确定任务群组内的各个任务在单位时间内所允许的运行时间。
具体的，在单位时间内，若任务群组内的任务的优先级不同，则将任务群组内的任务按照优先级高低顺序进行排序，优先级高的任务排在优先级低的任务前面，任务群组内的任务的资源使用时间可根据任务优先级高 低并按照预定的算法进行确定。例如，2T单位时间内，无任务群组外的任务正在执行，假定任务群组的资源使用时间额度为2L，任务群组内包括任务D、E，任务D的优先级高于任务E，则任务D可分得4L/3的资源使用时间，任务E分得2L/3的资源使用时间。当任务群组内的任务不在对应的运行时段时，任务群组内的任务分别立即进入等待状态。
上述资源管理方法，群组内的各个任务在单位时间内只在其对应的运行时段内运行，且根据任务群组内的任务的优先级高低确定资源使用时间，能更好地运行任务，既能保证群组内的工作完成，又能减少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
在另一个实施例中，步骤确定任务群组的各个任务在单位时间内所允许的运行时间，还包括以下步骤：
(1)获取正在执行的任务群组外的任务与任务群组内的任务的优先级。
具体的，若单位时间内，除任务群组内的任务，还有任务群组外的任务正在执行，则任务群组外的任务将与任务群组内的任务形成资源竞争。获取正在执行的任务群组外的任务及任务群组内的每个任务的优先级，并根据优先级的高低确定各个任务的资源使用时间。通常，优先级高的任务比优先级低的任务会获得更多的所允许的运行时间。
(2)判断任务群组外的任务与任务群组内的任务的优先级是否相同，若是，则执行(3)，若否，则执行(4)。
(3)确定任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组外的任务与任务群组内的任务的数量之和。
具体的，在单位时间内，若任务群组外的任务与任务群组内的任务的优先级相同，则任务群组内的各个任务在单位时间内所允许的运行时间为 任务群组的资源使用时间额度除以任务群组外的任务与任务群组内的任务的数量之和。例如，在图3中，第四个2T单位时间内，假定任务群组10的资源使用时间额度为T，共有一个任务群组外的任务C和三个任务群组内的任务E、H、I，则平均每个任务获得T/4的资源使用时间。而任务群组外的任务C还能获得单位时间内任务群组的资源使用时间额度外的时间T，则在单位时间内，任务群组外的任务C共能分到T+T/4的资源使用时间。在其它的实施例中，当任务群组外的任务与任务群组内的任务的优先级相同时，任务群组外的任务与任务群组内的任务可各分得一半的任务群组的资源使用时间额度，任务群组内的各个任务所允许的运行时间为一半的任务群组的资源使用时间额度除以任务群组内的任务数量。例如，在单位时间内，任务群组的资源使用时间为T，任务群组中包括任务E、F、G，则任务E、F、G总共获得T/2的资源使用时间，每个任务各获得T/6的资源使用时间，而任务群组外的任务则获得T+T/2的资源使用时间，分配方式与操作系统中的任务调度器算法相关。
(4)基于任务群组外的任务与任务群组内的任务的优先级高低并按照预定的算法确定任务群组内的各个任务在单位时间内所允许的运行时间。
具体的，在单位时间的资源使用时间内，若任务群组外的任务与任务群组内的任务的优先级高低不同，任务群组内的任务所允许的运行时间可根据任务群组外的任务和任务群组内的任务优先级高低并按照预定的算法进行确定。
上述资源管理方法，群组内的各个任务在单位时间内只在其对应的运行时段内运行，且根据任务优先级确定任务的资源使用时间，可以更好地进行资源调度，完成工作，当群组内的各个任务在对应的运行时段之外时，使各个任务分别进入等待状态，且群组内所有任务的所允许的运行时间之和不超过群组的资源使用时间额度，既能保证群组内的工作完成，又能减 少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
如图6所示，在一个实施例中，在步骤在单位时间内，当任务群组的各个任务在对应的运行时段之外时，使任务群组的各个任务分别进入等待状态，还包括：
步骤S610，判断当任务群组的各个任务均进入等待状态时是否有任务群组外的任务正在执行，若是，则执行步骤S620，若否，则执行步骤S630。
具体的，单位时间内，当任务群组内的任务全部进入等待状态时，若有任务群组外的任务正在执行，则确定该正在执行的任务群组外的任务获得全部的资源使用时间，若无任务群组外的任务正在执行，则可进入休眠状态，其中，进入休眠状态指执行上述资源管理方法的设备进入休眠状态已达到省电的目的。例如，如图7所示，在第一个2T单位时间内，当任务群组10内的任务E运行达L时间后，其进入等待状态，而在此之前，任务群组10内的任务D已进入等待状态。在任务E进入等待状态后，只有任务群组外的任务A在执行，则任务A获得全部的资源使用时间，可以使任务群组外的任务有更佳的资源使用效率。在第二个2T单位时间内，当任务群组10内的任务D、E、F均进入等待状态后，且无任务群组外的任务正在执行，正进入休眠状态。
步骤S620，将确定任务群组外的任务获得全部的资源使用时间。
步骤S630，进入休眠状态。
上述资源管理方法，当群组内的所有任务均进入等待状态且无群组外的任务执行时，进入休眠状态，可减少设备电力消耗。
如图8所示，一种资源管理系统，包括任务确定模块810、第一判断模块820、群组时间确定模块830、运行时间确定模块840和等待模块850。
任务确定模块810，配置为确定任务群组内的任务及与任务群组内的每个任务对应的预设的任务时间。
具体的，预设的任务时间为预设的任务群组内的任务在单位时间内可获得的资源使用时间上限，即任务群组内的每一项任务在单位时间内的运行时间不超过与之对应的任务时间，在本实施方式中，可设定任务群组内所有任务对应的预设的任务时间是相同的。例如，假设单位时间为2T，任务时间为L，L可为T/2、T/4等。每2T单位时间内，任务群组内的每一项任务最多只能使用L时间的资源。T可以为10s(秒)、15s、20s等时间较短的数值。资源可为CPU、GPU、内存等。可以理解地，任务群组内的每个任务对应的预设的任务时间可以根据实际需要进行设定，不一定完全相同。
第一判断模块820，配置为判断任务群组内所有任务对应的预设的任务时间之和是否小于预设的时间阈值。
具体的，时间阈值为预先设定的任务群组在每单位时间内的资源使用时间上限。单位时间、时间阈值、任务时间需可根据需求进行设定，三者的关系为单位时间大于时间阈值，时间阈值大于任务时间。比较任务群组内所有任务对应的预设的任务时间之和与时间阈值的大小，若任务群组内所有任务对应的预设的任务时间之和小于时间阈值，则确定任务群组在单位时间内的资源使用时间额度为任务群组内所有任务对应的预设的任务时间之和，若任务群组内所有任务对应的预设的任务时间之和不小于时间阈值，则确定任务群组在单位时间内的资源使用时间额度为时间阈值。如图2所示，包括任务群组外的任务20及任务群组10。其中，设定任务群组10内任务D、E对应的预设的任务时间均为L，时间阈值为T，在第一个2T单位时间内，任务群组10内的任务D、E对应的预设的任务时间之和为2L，小于预设的时间阈值T，则任务群组10的资源使用时间额度为2L。在第二个2T单位时间内，任务群组10包括任务D、E、F，设定任务群组10内任务D、E、F对应的预设的任务时间均为L，则任务群组10内的任务D、E、F对应的预设的任务时间之和为3L，大于时间阈值T，则任务群组10的资源使用时间额度 为T。在单位时间内，任务群组内的所有任务所允许的运行时间之和小于或等于任务群组的资源使用时间额度。
群组时间确定模块830，配置为当任务群组内所有任务对应的预设的任务时间之和小于预设的时间阈值时，则确定任务群组的资源使用时间额度为任务群组内所有任务对应的预设的任务时间之和。
具体的，通过比较任务群组内所有任务对应的预设的任务时间之和和时间阈值来确定任务群组的资源使用时间额度，可避免当任务群组内的任务数量太少时造成的资源浪费，将任务群组中的每个任务所获得的资源使用时间控制在合理范围内。例如，设定单位时间为2T，时间阈值为T，任务群组中只有一个任务，且该任务对应的预设的任务时间为T/4，若不通过比较任务群组内所有任务对应的预设的任务时间之和和时间阈值来确定任务群组的资源使用时间额度，则该任务在2T单位时间内可使用T时间的资源，此时可能会造成资源使用效率低等问题，而通过比较再确定任务群组的资源使用时间额度后，该任务在2T单位时间内最多只可使用T/4时间的资源，能提高资源的使用效率。
群组时间确定模块830还配置为当任务群组内所有任务对应的预设的任务时间之和不小于预设的时间阈值时，则确定任务群组的资源使用时间额度为该时间阈值。
运行时间确定模块840，配置为确定任务群组的各个任务在单位时间内所允许的运行时间。
具体的，将时间划分为连续的多个单位时间进行监测，任务群组的任务只在单位时间中的部分时段内才拥有资源使用权，即任务群组中的每个任务仅在与其对应的部分时段被运行，该部分时段的时长等于前述确定的所允许的运行时间。任务群组内的所有任务在单位时间内所允许的运行时间之和小于或等于前述确定的任务群组的资源使用时间额度。
等待模块850，配置为在单位时间内，当任务群组的各个任务在对应的运行时段之外时，使任务群组的各个任务分别进入等待状态。
具体的，在单位时间内，只有在任务群组的各个任务对应的运行时段内时，才执行该任务，该运行时段的时长等于该任务在单位时间内所允许的运行时间。图3为一个实施例中任务群组的任务执行时的示意图，如图3所示，在第二个2T单位时间内时，假定任务群组10的资源使用时间额度为2L，任务E、F所允许的运行时间均为2L/3，在任务E、F各自对应的运行时段内，执行该任务，当在各自对应的运行时段之外时，任务E、F则分别处于等待状态。等待状态指该任务不会使用任何资源。任务E、F所允许的运行时间之和小于任务群组10的资源使用时间额度2L。在第三个2T单位时间内，假定任务群组10的资源使用时间额度为T，任务E、F、G所允许的运行时间均为T/3，在任务E、F、G各自对应的运行时段内，执行该任务，当在各自对应的运行时段之外时，任务E、F、G则分别处于等待状态。任务E、F、G所允许的运行时间之和等于任务群组10的资源使用时间额度T。只需保证在单位时间内任务群组内所有的任务所允许的运行时间之和小于或等于任务群组的资源使用时间额度即可，而任务群组内的各个任务在单位时间的什么时段内运行则由操作系统的任务调度器的算法决定。在其它实施例中，任务群组内的任务在单位时间内，可先进入等待状态，再进行执行，例如2T单位时间内，任务群组内的所有任务先进入等待状态，T时间后，再按照任务群组内的各个任务所允许的运行时间执行各个任务，可以理解，其本质上与图3的资源管理系统是一致的。
在一个实施例中，上述资源管理系统还包括建立模块。
建立模块，配置为建立任务群组，并根据预定的规则将特定的任务添加入该任务群组。
具体的，建立任务群组对任务进行管理，只有在该任务群组中的任务， 才受任务群组的资源使用时间额度的限制。任务群组中的任务可为不需与用户进行交互的后台任务，例如邮件服务、讯息传递、自动保存等后台任务。将某些任务添加入任务群组中并进行资源使用限制，既可保证任务群组内的任务正常执行，也可避免任务群组内的任务无限制地与任务群组外的其它任务抢占资源，造成资源浪费。可以理解地，还可以根据需要设定其它的规则，然后将符合规则的特定任务添加到任务群组中。
上述资源管理系统，通过比较该任务群组内所有任务对应的预设的任务时间之和及预设的时间阈值大小，以此决定群组的资源使用时间额度，能够根据群组内的每个任务对应的预设的任务时间动态控制群组内的任务所能使用的资源，确保群组内每个任务所获得的资源使用时间在合理范围内，提高资源使用效率，节约资源。此外，群组内的各个任务在单位时间内只在其对应的运行时段内运行，既能保证群组内的工作完成，又能减少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
如图9所示，在一个实施例中，运行时间确定模块840包括获取单元842、判断单元844和确定单元846。
获取单元842，配置为获取任务群组内的任务的优先级。
具体的，在单位时间内，任务群组内的任务可最多获得任务群组的资源使用时间额度的资源。若此时，无任务群组外的任务在执行，任务群组内的任务无需与任务群组外的其它任务竞争资源，任务群组内的任务所允许的运行时间可根据任务的优先级高低并按照预定的算法进行确定。通常，任务群组内优先级高的任务比优先级低的任务会获得更多的所允许的运行时间。
判断单元844，配置为判断任务群组内的任务的优先级是否相同。
具体的，若任务群组内的任务的优先级相同，则任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任 务群组内的任务数量，若任务群组内的任务的优先级不同，则根据任务的优先级高低并按照预定的算法确定任务群组内各个任务在单位时间内所允许的运行时间。
确定单元846，配置为当任务群组内的任务的优先级相同且没有任务群组外的任务正在执行，则确定任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组内的任务数量。
具体的，例如，如图5所示，在第一个2T单位时间内，无任务群组外的任务正在执行，假定任务群组10的资源使用时间额度为2L，任务群组10内包括任务D和任务E，任务数量为2，则任务D和任务E各分得L的资源使用时间；在第二个2T单位时间内，无任务群组外的任务正在执行，假定任务群组的资源使用时间额度为T，任务群组10内包括任务D、E、F，则任务D、任务E和任务F各分得T/3的资源使用时间。在其它的实施例中，若还有任务群组外的任务正在执行，则任务群组内的任务所允许的运行时间将小于本实施例中获得的资源使用时间。
确定单元846还配置为当任务群组内的任务的优先级不同，则基于任务群组内的任务的优先级高低并按照预定的算法确定任务群组内的各个任务在单位时间内所允许的运行时间。
具体的，在单位时间内，若任务群组内的任务的优先级不同，则将任务群组内的任务按照优先级高低顺序进行排序，优先级高的任务排在优先级低的任务前面，任务群组内的任务的资源使用时间可根据任务优先级高低并按照预定的算法进行确定。例如，2T单位时间内，无任务群组外的任务正在执行，假定任务群组的资源使用时间额度为2L，任务群组内包括任务D、E，任务D的优先级高于任务E，则任务D可分得4L/3的资源使用时间，任务E分得2L/3的资源使用时间。当任务群组内的任务不在对应的运行时段时，任务群组内的任务分别立即进入等待状态。
上述资源管理系统，群组内的各个任务在单位时间内只在其对应的运行时段内运行，且根据任务群组内的任务的优先级高低确定资源使用时间，能更好地运行任务，既能保证群组内的工作完成，又能减少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
在另一个实施例中，获取单元842还配置为获取正在执行的任务群组外的任务与任务群组内的任务的优先级。
具体的，若单位时间内，除任务群组内的任务，还有任务群组外的任务正在执行，则任务群组外的任务将与任务群组内的任务形成资源竞争。获取正在执行的任务群组外的任务及任务群组内的每个任务的优先级，并根据优先级的高低确定各个任务的资源使用时间。通常，优先级高的任务比优先级低的任务会获得更多的所允许的运行时间。
判断单元844还配置为判断任务群组外的任务与任务群组内的任务的优先级是否相同。
确定单元846还配置为当任务群组外的任务与任务群组内的任务的优先级相同时，则确定任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组外的任务与任务群组内的任务的数量之和。
具体的，在单位时间内，若任务群组外的任务与任务群组内的任务的优先级相同，则任务群组内的各个任务在单位时间内所允许的运行时间为任务群组的资源使用时间额度除以任务群组外的任务与任务群组内的任务的数量之和。例如，在图3中，第四个2T单位时间内，假定任务群组10的资源使用时间额度为T，共有一个任务群组外的任务C和三个任务群组内的任务E、H、I，则平均每个任务获得T/4的资源使用时间。而任务群组外的任务C还能获得单位时间内任务群组的资源使用时间额度外的时间T，则在单位时间内，任务群组外的任务C共能分到T+T/4的资源使用时间。在其它的 实施例中，当任务群组外的任务与任务群组内的任务的优先级相同时，任务群组外的任务与任务群组内的任务可各分得一半的任务群组的资源使用时间额度，任务群组内的各个任务所允许的运行时间为一半的任务群组的资源使用时间额度除以任务群组内的任务数量。例如，在单位时间内，任务群组的资源使用时间为T，任务群组中包括任务E、F、G，则任务E、F、G总共获得T/2的资源使用时间，每个任务各获得T/6的资源使用时间，而任务群组外的任务则获得T+T/2的资源使用时间，分配方式与操作系统中的任务调度器算法相关。
确定单元846还配置为当任务群组外的任务与任务群组内的任务的优先级不同时，则基于任务群组外的任务与任务群组内的任务的优先级高低并按照预定的算法确定任务群组内的各个任务在单位时间内所允许的运行时间。
具体的，在单位时间的资源使用时间内，若任务群组外的任务与任务群组内的任务的优先级高低不同，任务群组内的任务所允许的运行时间可根据任务群组外的任务和任务群组内的任务优先级高低并按照预定的算法进行确定。
上述资源管理系统，群组内的各个任务在单位时间内只在其对应的运行时段内运行，且根据任务优先级确定任务的资源使用时间，可以更好地进行资源调度，完成工作，当群组内的各个任务在对应的运行时段之外时，使各个任务分别进入等待状态，且群组内所有任务的所允许的运行时间之和不超过群组的资源使用时间额度，既能保证群组内的工作完成，又能减少与群组外的任务资源竞争，使群组外的任务拥有更佳的资源使用效率。
在一个实施例中，上述资源管理系统，除了包括任务确定模块810、第一判断模块820、群组时间确定模块830，运行时间确定模块840及等待模块850，还包括第二判断模块和休眠模块。
第二判断模块，配置为判断当任务群组的各个任务均进入等待状态时是否有任务群组外的任务正在执行。
具体的，单位时间内，当任务群组内的任务全部进入等待状态时，若有任务群组外的任务正在执行，则确定该正在执行的任务群组外的任务获得全部的资源使用时间，若无任务群组外的任务正在执行，则可进入休眠状态，其中，进入休眠状态指执行上述资源管理方法的设备进入休眠状态已达到省电的目的。例如，如图7所示，在第一个2T单位时间内，当任务群组10内的任务E运行达L时间后，其进入等待状态，而在此之前，任务群组10内的任务D已进入等待状态。在任务E进入等待状态后，只有任务群组外的任务A在执行，则任务A获得全部的资源使用时间，可以使任务群组外的任务有更佳的资源使用效率。在第二个2T单位时间内，当任务群组10内的任务D、E、F均进入等待状态后，且无任务群组外的任务正在执行，正进入休眠状态。
运行时间确定模块840还配置为当任务群组的各个任务均进入等待状态时有任务群组外的任务正在执行，将确定该任务群组外的任务获得全部的资源使用时间。
休眠模块，配置为当任务群组的各个任务均进入等待状态时没有任务群组外的任务正在执行，进入休眠状态。
上述资源管理系统，当群组内的所有任务均进入等待状态且无群组外的任务执行时，进入休眠状态，可减少设备电力消耗。
本发明实施例还提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，该计算机可执行指令配置为执行上述实施例中任一项所述的资源管理方法。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只 要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
