22. Transition from PXI to PXIe Currently evaluating with NI best configurations MRF develops with Cosylab a PXIe event receiver card Prototype in december, final product in May 2012 Evaluation before EoY Windows (8 GB) vs. LV-RT (4 GB) For all applications except beam diagnostics PR-111003-a-JGU, October 9th, 2011 J.

23. Wish List - Brainstorm Shared variable engine performance evaluations and tuning Maybe common project on publisher/subscriber? DIM usage failed due to problems on LV-RT Hypervisor evaluation Tuning of application’s memory tuning Are you interested in REDNet? Are you interested in FECOS? PR-111003-a-JGU, October 9th, 2011 J.
