I have never seen this before on this machine, or any other machine I have used to crunch for SETI@home. Every workunit I downloaded the other day is a .vlar. Not sure what that means if anything, but thought I would run it by here to see why this is the case.

Is that good or bad? I got a bunch also
but the only thing I notice is they take longer.

That's preferable over shorties, isn't it?
Or none at all?

On my machine VLARs pay apx 2000 cr per day vs 1500 per day for shorties. I do not think that is right but that is a subject for a different thread.

Credits or etc don't concern me at all. My main concern: Is this normal? I mean I have downloaded a few .vlar here and there before, but never every single workunit in one download bundle. I just thought it to be odd...

Just be lucky to get something to crunch... ;-)
You'll get what is processed I assume, so nothing to worry I would suppose.

From 17fe11aa, 27fe11ag, and 20ap11ab. Having 3 of the tapes being split at some time be mainly VLAR work is probably just the obverse of having almost all VHAR work sometimes (shorty storm).

Usually when one spot is observed long enough to produce VLARs, the telescope is slewed to a new position after a few minutes. Those quick motions add some non-vlar WUs, but the big guns with CUDA cards grab those quickly. A splitter might produce 4 groups (1024 WUs, 2048 tasks) of VLAR, then 1 or 2 groups of midrange or VHAR while the telescope was moving to the next observing position.

Mad, the lower credit rate makes it harder for me to get my toaster.

Your toaster has been awaiting collection for some time now in the car park at Milliways

VLAR WU's have more data to process and are typically of more value to the science
