随笔分类 - Fast&slow Pointer [Leetcode 19]删除链表中倒数第N个元素Remove Nth Node From End of List 摘要:题目 删除链表head中倒数第N个元素 Given the head of a linked list, remove the nth node from the end of the list and return its head. Example 1: Input: head = [1,2,3 阅读全文...
思路:快慢指针分别定义一个快指针fast和慢指针slow,快指针一次走两步,慢指针一次走一步。如果链表没有环,那么fast最终会指向nullptr;如果链表有环,那么快指针和慢指针最终会相遇。所以,如果最终fast==nullptr,那么判断链表无环;如果最终fast==slow,且fast!=nullpt 链表 快慢指针 转载 f1yinsky 2019-04-02 23...
ok, new day, new node on the HPC and the problem seems gone. While GPU is still not (significantly) faster, it's also not slower than CPU. The training is super fast anyway (1:30min for 15M cells), feel free to close. I am having more GPU issues with batch effect correction, ...
Following advice of @ptillet on Slack I get the pointer update out of the for loop in the first kernel. # for reproductible experiments # sudo nvidia-smi -pm 1 -i 0 # sudo nvidia-smi -i 0 -pl 350 # 400 for A100 # sudo nvidia-smi -i 0 -lgc 1005 import torch import triton im...
Problem #1 –how to mark an object while being used?– in non-Concurrent Mark phase MethodTable pointers is used for this. But now, while the application is running and may access this pointer, it is not the best place ever Problem #2 –how to get a consistent view while references are...
Also, you can fetch data through a 1D texture bound to gmem pointer, writing back to gmem. This is safe in this case, despite the cache being only read-aware, since Warshall-Floyd algorithm is correct no matter whether you read the ik and kj distances from the previous step, or updated...
