library characterization (liberate) 并行度设置调优

阅读更多关于 library characterization (liberate) 并行度设置调优

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> library characterization，简称k库，意为特征参数提取，一般用于提取stand cell，io，ip，memory等的timing和power信息，常用工具为cadence家的liberate（以及提取lvf信息的variety，用于memory的liberate_mx），以及synopsys家siliconsmart。 c家的liberate市场占用率更高，以此为例说明。提升k库速度的关键是提升并行度，liberate提升并行度的主要方法是采用packet_client模式（默认是arc_packet，就是基于arc做任务划分），其模式如下图所示。主的liberate启动后，通过bsub的方式将辅的liberate投递出去，每个辅的liberate可以启动多进程，每个liberate进程会起一个spectre来做仿真，而spectre本身还可以采用多线程提高并行度。跟仿真并行度相关的设置有： 1. set_var packet_clients <NUM> 2. char_library -thread <NUM> 3. set_var extsim_cmd_option "+mt=<NUM> ***" 简单说明一下这几个参数。 #1， packet

阅读更多关于 Writing Cython extension: how to access a C struct internal data from Python?

问题 Disclaimer: I took the following example from the Python Cookbook (O'Reilly). Let's say I have the following simple struct : typedef struct { double x,y; } Point; with a function that calculates the Euclidean distance between two Point s: extern double distance(Point* p1, Point* p2); All this is part of a shared library called points : points.h - the header file points.c - the source file libpoints.so - the library file (the Cython extension links against it) I have created my wrapping Python

Python wrapper preventing function call?

问题 I've written a bunch of helper functions to wrap common functions such as insert and select. Included below is just one of those wrappers... which I can't seem to figure out why it isn't working. I suspect it is something to do with the wrapper: from collections import Mapping import sqlite3 def counter(func): def wrapper(*args, **kwargs): wrapper.count = wrapper.count + 1 wrapper.count = 0 return wrapper @counter def insert(val, cursor, table="reuters_word_list", logfile="queries.log"): if

问题 I want to create a wrapperClass for strings. I also want the class to be able to return the address of the wrapperClass and the address of the stored (wrapped) string: void FunctionString(string*); void FunctionWrappedString(wrappedString*); int main(){ wrappedString wrappedStringObject; FunctionString(&wrappedStringObject); FunctionWrappedString(&wrappedStringObject); wrappedString anotherWrappedStringObject; if(wrappedStringObject == anotherWrappedStringObject){ // code } } Here are the

阅读更多关于 ( C# / VB FFMPEG Wrapper ) How can I parse progress of conversion video to audio?

问题 I'd try to become specific as much as I can . I searched a lot to find a good .net wrapper for FFMPEG, the best was VB FFmpeg Wrapper I'm so bad at using VB.net, and the problem was that I want to use this library in a C# project but I couldn't convert the example program I found from VB.net to C# correctly . So, I've edited my C# application, so it writes input video file path to a temporary .txt file .. then run the "Converter" ( Which is written in VB ) ! The code of my "Converter" :

问题 I would like to design a wrapper in C++ with a simple syntax: Vector<double,stl> v; // aka std::vector<double> Vector<double, eigen> w; // aka Eigen::VectorXd from Eigen library Matrix<double, eigen> m; // aka Eigen::MatrixXd from Eigen library However, I do not manage to get this syntax, especially for the two last examples. Here is my code for the case of wrapping of STL vectors: #ifndef WRAPPER_HPP #define WRAPPER_HPP #include <cstdlib> #include <vector> //============= // BASE WRAPPER //=

问题 I'm trying to build caffe with the python wrapper on Mac OSX 10.0, but keep getting the following error when I execute the command: make runtest (make all -j8 and make test work fine). Check failed: error == cudaSuccess (35 vs. 0) CUDA driver version is insufficient for CUDA runtime version I have updated the CUDA driver to the latest version online. I also tried uninstalling and reinstalling CUDA and the driver, but the error still persists. How can I solve this? 回答1: As was teased out in
