Abstract:A popular selling point of diffusion large language models (dLLMs) is their capacity for parallelism: the ability to generate sequences of text far more efficiently than autoregressive models, which require one forward pass per token. Yet among the many competing paradigms for dLLMs, from masked to uniform to Gaussian diffusion, principled understanding of how these different proposals compare in parallelism remains limited. In this work, we initiate a fine-grained comparison of the capacity for parallelism among these three leading approaches and prove the following:

tomact自启动设置

Sat, 29 Jul 2017 11:56:14 +0800

该部分内容来源于网络，本人测试，功能正常，留下备忘。

适用于Tomcat4.1、5.5、6.0。

因为解压缩版的Tomcat，在windows服务上没有启动项，所以需要手动添加，然后可以设置开机启动tomcat。

一、安装服务

在命令行中进入/Tomcat路径/bin/，执行“service.bat install”：（开始-运行,输入cmd,cdTomcat路径/bin,service.bat install）。到此为止windows服务上就增加了一个tomcat服务

说明：

1、服务名和显示名称：service.bat中设置了默认的服务名称，不同版本分别命名为Tomcat4、Tomcat5、Tomcat6，如果需要自定义服务名或服务的显示名称，可在service.bat中修改SERVICE_NAME或PR_DISPLAYNAME；

2、防火墙的影响：/bin/tomcat6.exe（或tomcat4.exe、tomcat5.exe）将被作为服务程序，如果有防火墙，需要设为允许作为服务。

二、卸载服务

在命令行中进入/Tomcat路径/bin/，执行“service.bat remove”：

三、命令行参数

Tomcat的服务名、Jvm内存初始值和最大值等可通过命令行参数设置，请参考官方文档：

http://tomcat.apache.org/tomcat-5.5-doc/windows-service-howto.html

http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html

四、开机启动Tomcat设置

开始-控制面板-管理工具-服务

找到apche tomcat?右键属性，把手动改为自动
