Hi John, Unfortunately I read the email only now. From an organizational point of view I think we could start the discussion of this topic and then maybe work on a UR 2.1 definition. 2.0 was sent for public comment one month ago so I think that this version should continue its track. I think that among the options that you are proposing I would choose one of the first two. Anyway I have to think a bit more about it. Maybe we can discuss it during next phone meeting. we keep our schedule it should be next Tuesday the 16th of April at 15:00. As some of us are in fact busy at EGI CF 2013 I would suggest to fix next phone meeting either the 23rd or the 30th of April at the same time. What are your preferences?

Guys, there is a workshop today on use of GPGPU in EGI. I am looking at accounting. Has anyone considered how we include this in UR2?
Options I thought of are:
1. Extend the computeusageblock - have a second field for CPU used on attached processor. This would also need some way to identify the type. Currently we have a count of processors and the sum of cpu use. We can't add CPU+GPU so we would need to duplicate several fields
2. Repeat the computeusageblock - there is no identifier that would distinguish between 2 instances of the block. If there were then we could have two instances, one for CPU and one for GPU. The fields like, cpu count and total CPU would be different in each and could be treated separately or together because they are recorded together in the same UR. Another problem is that we do not identify the type of processor so we could not parse to distinguish between multiple blocks.
3. A new block AttachedProcUsageBlock
Any other thoughts?
John
