Hi Cedric,

 

I’m using the StarPU version from the SVN repository. The virtual machine is a VMware and it runs on Windows XP. Inside the virtual machine I an running a Suse Linux.

Here are the logs from configuration and make check.

 

Best Regards,

Hello Alin,

Thanks a lot for taking some time to report this!

So far, i don't think we tested StarPU from a virtual machine, but to see what is actually happening, could you please send us the config.log file generated when you called configure ? This should show us which librairies were found during the configuration. Normally, you don't need any particuliar lib, except hwloc that can be helpful even though it's not strictly required.

It would also be helpful if you could add --enable-verbose when configuring StarPU. StarPU would then display which processing units were found during its initialization phase. I'm not sure nvidia drivers (either for CUDA or OpenCL) would work through a virtual machine but perhaps i'm wrong, in that case, StarPU would only find CPUs, and the matvecmult example is using exclusively OpenCL. I suspect you did not install an OpenCL lib that supports CPUs too (only AMD's implementation can as far as i know). Could you please send us the output of "make check" with this --enable-debug option ?

Which version of StarPU do you use, from the svn repository or the "daily tarball" ? On which OS are you running the virtual machine ?

Best,
Cédric

Hello,

 

I am having some trouble with configuring the StarPU.

I checked out the StarPU from the SVN link provided, and I followed the steps in the StarPU documentation to configure, make and install (on Linux running in virtual machine).

However, when I try to run the matvecmult example (or any other for that matter), I get the “No worker may execute this task” message.

 

Is there something that was not configured properly?

Do I need additional HW to be in my system? (like a specific graphics card for instance?)

I tried to install it also on a PC that has an nVidia graphics card and I still get the same message.

Is there any other SW package that needs to be installed in order for StarPU to run? (like some additional libraries?)

 

Best Regards,

Alin Dobre
