Project Overview
TopCoder Competition Engine is a system used for Single Round Matches (SRM) and Marathon Matches (MM).
Competition Task Overview
Current Situtation
Recently, we have updated our production environment to x64 OS, but there is a limitation for running .NET solutions (C# and VB.NET), as the
TestProcess.exe and LongWrapper.exe
used by windows processor are compiled with
/platform:x86
option, you can see https://github.com/cloudspokes/app/blob/master/build_csharp.xml.
<target name="build-csharp" depends="init-csharp" description="Builds CSharp test harness">
<dn:csc srcDir="${csharp.main.dir}" targetType="exe" mainClass="TopCoder.Server.Controller.CTMain"
references="${csharp.lib.dir}/Microsoft.VisualBasic.dll;${csharp.lib.dir}/TopCoder.Io.Serialization.BasicType.dll" outputFile="${build.dotNet}/DotNetCompilerTester.exe" />
<!-- debuy="true" can be added -->
<dn:csc srcDir="${csharp.main.dir}" extraOptions="/platform:x86" targetType="exe" mainClass="TopCoder.Internal.LongWrapper"

</target>
This limits to use large memory, like big than 2GB.
Expectation Solution
We'd like to remove the extraOptions limit.
So please look into the implementation of TestProcess, and make it properly work under x64 architecture environment.
The Fix should be applied to SRM and MM problem.
Please check the SRM Problem Guide and MM Problem Guide for reference.
About Code Base
For the code under /home/apps/dev directory, some are hosted in internal svn repositories, some are hosted in private repositories in github.
You can check Source Code Management For TopCoder Competition Engine - TopCoder Wiki
For SVN Access, please send request to support@topcoder.com, For github access, please post your github account in forum to ask PM to grant you access.
Arena VM Usage
Before asking your own VM, you need to have a public key on your profile before asking for the VM.
You can find more details on how to generate a key http://apps.topcoder.com/wiki/display/projects/Generate+SSH+Key and how to connect using it http://apps.topcoder.com/wiki/display/projects/Connect+Using+SSH+Key.
Please reference http://apps.topcoder.com/wiki/display/docs/Competition+Engine+VM+Setup for general usage.
Previously, we have made several update for the Arena VM. So when the Arena VM allocated is available for you, there is a problem and a SRM contest already setup, you can reuse that for testing.
Windows VM
processor should be properly setup in Windows VM in order to reproduce the problem and verify your fix.
a Windows VM will be provided to each competitor, and the login credential will be provided in forum.
