The advanced LIGO detector will start their first data taking run this Friday (Sep 18). For the searches Einstein@Home does in these data (continuous gravitational waves), several months of data are required.
The first measurement run called “O1†(observation run 1) will last for three months, so this could provide a useful data set for Einstein@Home searches.
So even while there will be fresh data later this week, a search for continuous gravitational waves needs to wait a little while.
The next thing we want and need to get out the door is the search for Gamma-Ray pulsars in binary systems. The original plan was to have at least a Beta test version out still this year, but that has been delayed by a few weeks. This will be a longer running search (of order a few years) that will initially be CPU only, but will most likely get a GPU version a few months after launch.
The next GW analysis run is currently being planned. It will analyze data from the first "observational" (science data taking) run ("O1") of the upgraded "Advanced LIGO" detectors, which is scheduled to finish mid January. This analysis is also the first E@H run that features our new "resampling" code, which should be significantly more efficient for all-sky broadband searches than what we used previously. According to current plans the analysis run will take only a few months. We will first aim to get the analysis going at all with CPUs, and then start to develop a GPU version. It is not yet clear to me whether we will succeed while that first O1 analysis is still running. But the GPU version should be available for future analysis runs, we will probably use the same code for the next couple of years.

Hi Bernd ! Thanks for this info. :-)
As for "resampling" code, I feel like I may have nodded off during a movie and missed a crucial plot point. Has this been mentioned before ( in a newsletter say ) or under a different name ?
{ I should have mentioned this earlier perhaps, but I haven't been getting any newsletters to date to my personal email address. I have read the newsletters as posted though. Not a biggie ... }
Cheers, Mike.

We intended to make use of this code (or the idea behind it) for a number of years, and I remember mentioning it occasionally (I found it mentioned in a post of 2011). Over the years it went through a number of incarnations / implementations, however until a few months ago we didn't really get it to work efficiently and reliably enough.
Any ETA for the new GW data

I've read the "Nature" article. Sounds very interesting, and also LISA Pathfinder is on its way.

Hi, will GPUs be able to crunch the next gravitational run?

I think there was a post recently from one of the Devs that basically said, "Probably CPU only to start with with a GPU app down the track a bit."
Or something like that :-).
