And speaking of those VLAR/VHAR/Normal units - regardless of perfomance issues, do they have the same value? I don't mean the points earned but the actual scientific value. At first glance it would appear that a quick sweep of a wide field of view would be less detailed but, on the other hand, you may need enough reference points along the arc for the processing. Could anyone comment please? S@H Enhanced processing is very much conditioned on the chance of finding a meaningful signal in the data. For instance, it doesn't try to find a repetitive pulse pattern unless there are at least 16 samples to work with at the specific bandwidth being examined. In effect, that makes the amount of analysis adapt appropriately for each WU so the value is roughly equal in that sense. That's not to say the value per crunch minute is constant, there's a lot of overhead involved in getting the data set up for analysis, etc. And there are some arbitrary limits on analysis which date back to the capabilities of CPUs in the 1999 era. Those are somewhat like the much more recent "don't send VLAR tasks to CUDA" limitation. Joe |

The kitties are happy to chase around all those itty bitty WUs if anybody else doesn't want them...LOL. "Freedom is just Chaos, with better lighting." Alan Dean Foster |
