Iterate over strings in assembly (NASM)

由 风流意气都作罢 提交于 2020-03-20 19:35:32
问题 I am trying to count the length of the string argv[1] in NASM assembly language. I think I'm on the right track. I have moved the address of argv[1] to register eax and now I want to move through it byte by byte and compare to the null string terminator. Everytime I run the code it segfaults on the null comparison. Am I not getting the memory indexing correct? *Disclaimer: This is a small part of a large homework assignment. segment .bss N: resd 1 ;counter for size of argv[1] segment .text

multiprocessing pool - memory usage

问题 I wrote a script that I deploy in an HPC node with 112 cores, thus starting 112 processes up to completing 400 needed ( node_combinations is a list of 400 tuples). The relevant snippet of code is below: # Parallel Path Probability Calculation # ===================================== node_combinations = [(i, j) for i in g.nodes for j in g.nodes] pool = Pool() start = datetime.datetime.now() logging.info("Start time: %s", start) print("Start time: ", start) pool.starmap(g._print_probability_path

Why is deinit not called until UIView is added to parent again?

由 旧街凉风 提交于 2020-03-20 06:25:50
问题 I have a UIView that am adding to a UIViewController and am generally testing de-initialization to make sure I am doing things right. But when I don't set the variable in my viewController to nil and only use .removeFromSuperView() , the deinit() method in UIView won't be called until I add the UIView another time then its called. But if I use removeFromSuperView() and set the variable to nil then deinit() is called right away. Why is that? Here's UIView() class: class TestView: UIView {

VCS仿真 Dump Memory 两种方法 vcs联合verdi生成fsdb文件 vcs生成vpd文件 VCS联合verdi生成fsdb文件 1.testbench中加入如下语句： initial begin $fsdbDumpfile("tb.fsdb"); $fsdbDumpvars; end always@(posedge clk) begin $fsdbDumpMDA(R1); //每个时钟dump出mem的值，verdi记录值的变化 $fsdbDumpMDA(R2); end 2.注意调用 vcs -debug_pp 开始仿真 3.测试使用的verilog代码与仿真脚本 testbench `timescale 1ns/100ps module Testbench; reg clk; integer i; reg R1[7:0]; reg [3:0] R2[7:0]; initial begin clk = 0; for (i=0; i<8; i=i+1) begin R1[i] = 1'b0; R2[i] = 4'h0; end #10; for (i=0; i<8; i=i+1) begin R1[i] = $random; R2[i] = $random; end repeat(5) @(posedge clk); for (i=0; i<8; i=i+1)

Mysql：The Memory Storage Engine

16.3 The MEMORY Storage Engine The MEMORY storage engine (formerly known as HEAP ) creates special-purpose tables with contents that are stored in memory. Because the data is vulnerable to crashes, hardware issues, or power outages, only use these tables as temporary work areas or read-only caches for data pulled from other tables. Table 16.4 MEMORY Storage Engine Features Feature Support B-tree indexes Yes Backup/point-in-time recovery (Implemented in the server, rather than in the storage engine.) Yes Cluster database support No Clustered indexes No Compressed data No Data caches N/A
