如何让R脚本在mosix集群上并行运行？

我试图重新创建的示例在的第3部分中给出，它在集群管理的多个实例上执行简单的计算。主要计算发生在脚本“sim.R”中：

这让我想到程序从未运行或进入集群队列。我还使用“top”命令检查了系统进程，没有发现任何问题。在记录中，我已经成功地在MoS6集群上运行简单的C++程序。

我是否错过了让该程序运行的关键细节？

如果将

rbatch.local.run（）

移动到循环之外会发生什么？@MrFlick我得到了相同的输出，尽管它以：rbatch.local.run（）rbatch.local.run（）结尾：没有批处理任何命令。空>

        pvalue[i] <- t.test(X, Y)$p.value
}
power <- mean(pvalue <= 0.05)

out <- data.frame(seed = seed, nsim = nsim, n = n,
        mu = paste(mu, collapse = ","),
        sd = paste(sd, collapse = ","), power = power)

print(out)
write.csv(out, outfilename, row.names = FALSE)

library("batch")
seed <- 1000
for(i in 1:10) {
        seed <- rbatch("sim.R", seed = seed, n = 25, mu = c(0, i / 10))
        rbatch.local.run() # My understanding from the linked paper is that this line will do nothing if the script is run on a mosix cluster and not locally.
}
