Is there a problem with BRP7?

Is there a problem with BRP7? Been out of work for a few hours now.

Sort of, I have to keep

Sort of, I have to keep banging on the update button and occasionally I'l pick up a few. This is a very tedious and painful process, but it works for me.

Most of your current tasks are resends (the number _2 at the end, normal ones are _0 or _1).  Looks like no new ones are currently being created.

If this page takes an hour to load, reduce posts per page to 20 in your settings, then the tinpot 486 Einstein uses can handle it.

Sorry, stuck in data

Sorry, stuck in data preparation. Fixed.

Bernd, is there somewhere

Bernd, is there somewhere that identifies the targets of the BRP7 searches?

I see new task generation with different task naming prefixes today.

The previous tasks prefixes looked like they were Messier catalog targets.  M22,M28 for example.

Coincidence?  Or actually the Messier objects?

Current tasks with the TER prefix does not jump out at me for any recognizable astronomical catalog.

[Edit]

Answering my own question, the ter5 tasks show the object in the task properties.

Terzan5/epoch1/J1748-2446N being the target which is in a small globular cluster in the bulge of the Milkyway galaxy.

Is it official that Gamma-ray

Is it official that Gamma-ray pulsar searches are done? I've been running on m1 native (macOS arm) for a little while, and these are the only tasks I've been getting for m1 native. Are there any other tasks I should be receiving for native m1? And is it the case those are done? I'll do non-native computation if needed, but would strongly prefer native.

I have one which has the following properties, I can't see the target in there:

The target isn't listed in the properties other than the series name.  To find out exactly where target is located you need to look at the stderr.txt result file which lists the RA/DEC coordinates.

All of the task naming so far as I know has been from standard star catalogues and the prefix of the taskname has always been the standard abbreviation of the star catalog the target is listed in.

Terzan — Agop Terzan Catalogue of Globular Star Clusters (11 objects)

No not official.  They just have advised that the Gamma Ray Pulsar search was winding down back in summer and only a few more months of work was available.  Then because they didn't get the BRP7 campaign ramped up as fast as they expected, they prolonged the GR#1 task generation for bit longer.

The scarcity of tasks is just because they haven't recovered the computers that do the pre-processing of those tasks from the last system wide project failure.

The end of these tasks could come at a moment's notice however.  I would start making plans for other work for your host.
