Hmm, ok... I guess if that's the way you want to run it. I've never really had any problems running multiple WUs within BOINC, the max I've got is 6 (4 CPU, 1 GPU, 1 NCI) on one host. I manage the heat on systems where that's a problem without any incident.

I too have run into situations that 2 clients solve. Mainly around supporting multiple gpus. Some projects have run into issues with 2 or more NVidia in the pc and not being able to run on all of them from one client. Also video cards with 2 engines (e.g. gtx 690) are some times a problem for projects and I split them off to different clients, when I want them both on the same project. Finally multi gpu issue that additional clients solve is when you have cards of different ability. For instance you have a titan and want to run 3 wus/gpu and you have another NVidia card that can't handle it. Simply put the titan in one client, the other card in another and setup up different app_config or app_info xmls as needed.

There are even more reasons I can think of in addition to the ones Nate1 listed below, but I think we have painted a sufficient picture of why. Only adding my thought hear in the hope it helps someone out.

It is working well for me. All 2nd clients are working and validating. Sorry I forgot to report back earlier.

I too had the initial problem where the .exe files disappeared, but I attributed that to stupidly trying the Linux original version of the app_info without looking at it first. I fixed the app_info.xml to the one I posted earlier, copied the exe from the 1st client to the second and it started working.

The app_info.xml is for Linux. Here is a windows version that seems to be working (at least the wus is running). I change the port to 2222 for my host. I will report back after work units from client 1 and client 2 complete and validate.

<app_info>
<app>
<name>data_collect_v4</name>
<user_friendly_name>Data collect version 4</user_friendly_name>
<non_cpu_intensive>0</non_cpu_intensive>
</app>
<file_info>
<name>data_collect_v4_4.13_windows_x86_64__nci.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>data_collect_v4</app_name>
<version_num>413</version_num>
<plan_class>nci</plan_class>

<max_ncpus>0.01</max_ncpus>
