[Bug 1095833] Re: Microsoft.Hpc.Scheduler test gets an exception
Same hang in 2.6.0 NUnit GUI with or without the change. I can try
console later today if you need me to.
To be more precise, the "hang" actually takes 10 minutes or so, after
which it comes back with this exception:
System.Net.Sockets.SocketException : A connection attempt failed because
the connected party did not properly respond after a period of time, or
established connection failed because connected host has failed to
respond

So it seems there are a couple of ways the test can fail.
You need to install the HPC cluster OS on a separate machine:
http://www.microsoft.com/en-us/download/details.aspx?id=13769
Apply this service pack:
http://www.microsoft.com/en-us/download/details.aspx?id=28017
On your dev machine, install the HPC Pack 2008 R2 SDK (http://www.microsoft.com/en-us/download/details.aspx?id=28016) and client utilities (http://www.microsoft.com/en-us/download/details.aspx?id=17017). These have the dlls I'm referencing:
Microsoft.Hpc.Scheduler.dll
Microsoft.Hpc.Scheduler.Properties.dll
Microsoft.Hpc.Scheduler.Session.dll
Microsoft.Hpc.Scheduler.Store.dll
Make sure you use the same version of the dlls (3.3.3950). Hopefully I
gave you the right links, but, if not, you can browse related downloads
and find the right version. Essentially, 3.3.3950 corresponds to service
pack 3 of HPC.

Title:
Microsoft.Hpc.Scheduler test gets an exception
Status in NUnit V2 Test Framework:
New
Bug description:
I have the following test:
using Microsoft.Hpc.Scheduler;
using NUnit.Framework;
namespace TestHPC
{
[TestFixture]
internal class TestHpc
{
[TestCase("HEAD-NODE-SERVER", 9)]
public static void AllCoresPresent(string headNode, int expectedCores)
{
int totalCores = 0;
using (IScheduler scheduler = new Scheduler())
{
scheduler.Connect(headNode);
ISchedulerCollection nodes = scheduler.GetNodeList(null, null);
foreach (ISchedulerNode node in nodes)
{
totalCores += node.NumberOfCores;
}
}
Assert.AreEqual(expectedCores, totalCores);
}
}
}
I am using a Visual Studio 2010 solution that has the project with
this test build against .NET 4.0. This is the only test in the
solution.
If I use NUnit 2.6.0 GUI or console runner, the test hangs in the
middle.
If I use ReSharper 7.1.1 Unit Test runner pointed at my local NUnit
2.6.0 and run the test from the project compiled against 2.6.0
nunit.framework.dll, the test passes quite quickly.
If I switch ReSharper to run tests with build-in NUnit 2.6.2 and
compile against 2.6.2, the test fails with this error:
Microsoft.Hpc.Scheduler.Properties.SchedulerException : No connection could be made because the target machine actively refused it 127.0.0.1:6729

If I use NUnit 2.6.2 GUI or console runner, the test hangs in the
middle.
There are no firewalls blocking port 6729 on the HPC server. All I did
was switch the version of NUnit.
There seems to be a difference in how ReSharper is launching NUnit
from the way NUnit GUI and console runner work. If I did not have
ReSharper, I would have no clue that my test could pass.
ReSharper's behavior is observed in TeamCity when I run the test using
NUnit runner. Looks like JetBrains have some consistency across their
products that work better for execution of NUnit tests than native
tools.
I have a variety of other tests that work just fine after the switch,
so the problem is constrained to Microsoft.Hpc.Scheduler tests (for
now). I can provide more information if needed. Please help!
