0.5.5版的更改:multicoreWorkers()的新特性根据操作系统(Windows: 1)、用户偏好(通过全局选项options(mc.cores=…))或系统能力(detectCores())来确定worker的数量。o bpparam()从全局选项中选择默认的BiocParallelParam，如果失败，则选择最近注册的()后端。重大用户可见的变化o重命名参数控制恢复错误为BPRESUME o默认并行后端(多核非windows;窗户上的雪)。任务少于内核的bpvec,ANY, multicoreparam方法只计算定义了任务的内核。0.5.2版的更改:mclapply()、pvec()的新特性只要求长度、[和(对于mclapply)[[。O pvectorize()创建其向量化函数参数的并行版本。o multicorepam, SnowParam, DoparParam (foreach-derived)， SerialParam用于参数化后端。O bplapply、bpvec作为并行评估模型。O bpstart, bpstop, bpisup用于后端管理。 o bpvec has a new argument AGGREGATE, a function to specify how results are to be combined. o Support for BatchJobs back-end added, via GSOC Michel Lang. SIGNIFICANT USER-VISIBLE CHANGES o BPPARM is now used as the argument name for passing BiocParallelParam instances to functions. o bplapply and bpvec now only dispatch on X and BPPARAM.
