OpenCL has no member enqueueBarrierWithWaitList()

[GPadley]

When trying to compile both test_opencl, v4 and v5 I am unable to use enqueueBarrierWithWaitList(); Giving the error below.

error: 'class cl::CommandQueue' has no member named 'enqueueBarrierWithWaitList'; did you mean 'enqueueBarrier'?

Changing this to enqueueBarrier() enables the programs to compile and run correctly on my machine. However, when @jjd06 run the tests, which function call will be used within the AWS instance or is it okay to use enqueueBarrier() instead?

[jjd06]

No. enqueueBarrierWithWaitList() is an OpenCL 1.2 feature, and should be usable (and used). Make sure that you have an up-to-date OpenCL install on the machine you're using.

I've been attempting to do this on my Windows 10 machine and have been unable to do so. I have changed my repo such that v4 and v5 are written with enqueueBarrierWithWaitList() however I am also unable to open up a g3 EC2 instance to test as free tier AWS account is blocking this.

The high-performance instances are not available for free. Have you requested credit through AWS Educate? There is a lead time for this. There's also typically a small delay (a few hours) in getting an instance the first time you try to launch one.

My account was already verified, limits are set on the free tier account on what instances you are able to use. I had to contact AWS to have the limit moved from 0 to 1 to allow me to use the specific instance.

Ah, good to know. So are the two issues (out-of-date OpenCL library and instance access) resolved now?
