Hello community,

We are trying to fix a problem in IO500 where certain results have been able to used client-side cache for the mdtest stat phase.  This is in violation of the intent of IO500 to measure non-cached behavior.  To fix this problem, we need to use the shift flag to mdtest as we have used it for IOR.  Unfortunately, this code path is fragile and doesn't work with the stonewall flag.  We are hoping to fix this by SC19 and to insist that all submissions do the shift for both mdtest and IOR and that all submissions use a fixed stonewall value of 300 for all phases.

So, is there anyone willing to help with this?  Nathan Hjelm was the last volunteer (beside Julian) to make a significant contribution to the code base and it was greatly appreciated.  We will be very grateful.  If there are any students who are willing to help with this, we would be very happy to help them with eventual references or similar tokens of gratitude!

Thanks very much and we hopefully await your enthusiastic responses!
