Some of the tasks I've had waiting to upload have done so. Other are still failing with the message

Thank you, nice to know how to see that.

But why would the sse2 version be faster than avx? Is this just a quirk of the particular application? Or is there a problem with the avx implementation on this particular cpu?

I recall a statement on the message boards that the server software tests your machine by running plain, sse2, and avx tasks and then sends you the task you machine does best.

My machine has a Xeon E3-1245 cpu which is AVX capable. But all the TN tasks I get are sse2. Is the previous description actually how it works? If so, can I tell why I'm only getting sse2 tasks?

Thanks
