invalid command queues using some testers

Postby MigMuc » Tue Oct 25, 2016 3:11 pm

I successfully compiled clmagma-1.3.0 and can run the examples. But I noticed that some of them
throw an error message
Code: Select all
OpenCL runtime error: CL_INVALID_COMMAND_QUEUE (-36) in magma_queue_sync at interface.cpp:255
.

This error message applies to the testing_[sdcz]swap and testing_[sdcz]transpose examples.

We're working on a new release of clMAGMA, and will look into this as part of that. It could be there's a bug in the tester.

Thank you for your quick response. I am looking forward to work with an improved clmagma release. I tested already some functions in MAGMA for CUDA using the
Fortran interfaces. I would really appreciate if you could also implement the out-of-core (hybrid) solvers magma_[sdcz]getrf since the matrices are rather large and GPU
memory is a bottleneck.
