Topic 218986

I've just noticed a new series of applications that have appeared on the Apps page.  They go under the name that Bernd previously mentioned - Gravitational Wave Injection run on LIGO O1 Open Data - and (at least so far) there are only GPU apps listed there.

I guess this suggests that the new run is about to kick off and that the match between CPU results and GPU results must have been good enough for the GPU app to be 'trusted' to give the correct answers on its own.  It will be very interesting to see if there are any efficiency improvements that have been found and incorporated in the new 'Injection' app as compared to the previous one.

The "Injection" in the name suggests that possibly there are 'simulated signals' incorporated in the data in order to test detection limits, although maybe it means something else :-).  If there are simulated signals, there should be some sort of 'reward' for the computers that find them.  That might encourage a higher take-up of the new search :-)

Here's hoping for a nice smooth launch :-).

Cheers,
Gary.

Ah well. My launch blew up

Ah well. My launch blew up sitting on the pad ..... :-(

For my Ubuntu box, I quickly ( time elapse = 0.0 ) get two tasks in error with this output :

process exited with code 127 (0x7f, -129)</message>

../../projects/einstein.phys.uwm.edu/einstein_O1OD1I_1.00_x86_64-pc-linux-gnu__GW-opencl-nvidia: relocation error: ../../projects/einstein.phys.uwm.edu/einstein_O1OD1I_1.00_x86_64-pc-linux-gnu__GW-opencl-nvidia: symbol __get_cpu_features version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

... pointing the finger of doubt at the shared system C library, or more likely the particular version of it.

Linux Ubuntu Ubuntu 18.04.2 LTS [4.15.0-50-generic|libc 2.27 (Ubuntu GLIBC 2.27-3ubuntu1)]

Cheers, Mike.

Now I'm just confused. There are no Linux 'Injection' apps listed on the Apps page, only Windows and Mac OS.  So Mike, where did you pick up the einstein_O1OD1I_1.00_x86_64-pc-linux-gnu__GW-opencl-nvidia app?  I'm curious to try the GW-opencl-ati version for my Ubuntu host.

 

 

Ideas are not fixed, nor should they be; we live in model-dependent reality.

There was also linux app available earlier... but looks like it's been taken away from the apps list. A good reason for cancelling it could be that it didn't work at all, like Mike saw.

I've got 6 in the que, that

I've got 6 in the queue, that excites me. The last time they got my RAC down to ~90K and I didn't care, I want to find a gravity wave.

I've got 2 in progress, I do 2 at a time, and 1 in the queue but none completed yet. On my AMD 480 they are expecting to run about 3 1/2 hours and are using mostly in the middle 30% of the gpu but do jump up to 100% at times. They download thinking they will take about 17 minutes each but are taking far longer.

My 1st one had an error in

My 1st one had an error in Windows. The RX 580 runs other tasks just fine.

These are my 2 completed ones, time will tell if they validate or not. I have another in progress right now.

How can I get WUs for

How can I get WUs for "Gravitational Wave Injection run on LIGO O1 Open Data"?

The application is not yet listed in the project settings. I tried different combinations, but don't get any WUs for Linux/NVIDIA.

Thank you.
