Fortran内部函数Random_seed() 下载积分: 100 内容提示: Intrinsic Subroutine (Generic): Changes or queries the seed (starting point) for the pseudorandom number generator used by intrinsic subroutine RANDOM_NUMBER. Intrinsic subroutines cannot be passed as actual arguments. 内部函数:改变或查询伪随机数...
最终得出的结论是异常导致threadLocal.remove()方法没有执行，最后内存泄漏了，以下是本人定位问题的过程。
Intel Fortran doesn't yet support that. What Intel does support is calling RANDOM_SEED with no arguments, causing it to give a different sequence each time. The standard doesn't specify this behavior, but many implementations do this. Translate 1 Kudo Copy link Reply ...

PUT(可选) 等级为 1 且大小 ≥ N 的INTENT(IN)INTEGER数组。 从它传输当前生成器的种子。 GET(可选) 等级为 1 且大小 ≥ N 的INTENT(OUT)INTEGER数组。 将当前生成器的种子传输到该种子。 GENERATOR(可选) INTENT(IN)INTEGER标量。 其值确定随后要使用的随机数生成器。 该值必须是 1 或 2。
设置seed()里的数字就相当于设置了一个盛有随机数的“聚宝盆”,一个数字代表一个“聚宝盆”,当我们在seed()的括号里设置相同的seed,“聚宝盆”就是一样的,那当然每次拿出的随机数就会相同(不要觉得就是从里面随机取数字,只要设置的seed相同取出地随机数就一样)。如果不设置seed,则每次会生成不同的随机数。(...

Random_seed では、ユーザーは 2 つの乱数発生ルーチンを切り替えることができます。 乱数発生ルーチン 1 がデフォルトです。 各乱数発生ルーチンは、1 つの専用シードを 保守し、通常は、最後の数を生成後にサイクルを再開します。 有効なシードは、乱数生成ルーチン 1 の場合は 1.0 ...
