New NBody test searches

Hello Everyone,

My name is Steve, I am a physics/math undergrad at RPI and have taken on the task of handling the nbody code for the summer. For the past few weeks I have been working on the comparison software that measures how well the simulations match the known data.

I just uploaded two searches, de_plum_slice_EMD_NEW_100K and ps_plum_slice_EMD_NEW_100K. Hopefully these will run smoothly but let me know if anyone has any problems.

Other than that if anyone has any questions about me, what I do, or about Milky Way at Home, please feel free to ask. I would be happy to answer them.

Getting computation errors on workunits named de_plum_slice_EMD_NEW_100K... all failing after 100% work done.

Also on ps_plus_slice workunits. same thing. Computes then comes back with a computation error when at 100%

All workunits ps & ds crunched are getting error when reached 100% of computation.

All have finished and ended with computation error.

* "System nemuze nalezt uvedenou jednotku." is in Czech, so I think it is error-message of the Windows XP SP3 CZ running on that computer.

- and it means: (Operating) System cannot find specified unit. (disk drive???)
I guess there is some problem with a PATH to some file. :)[/code]

Very interesting and weird Work-Unit! It has had veeeeery long run time for an NBody unit! :O how a pity it also errored out at 100 percent:

http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=195808492

MW@H 1.02 opencl_and n-body sim 0.80 showing computational error at 100%. Definitely weird.

Hi Steve,

Unfortunately these are also all producing a Computation error when they reach 100% for me too.

Cheers,

Chris

It appears, based on reviewing the stderr outputs of all of the users that have seen errors, that the application fails when reaching Histogram number 37

Error reading histogram line 37: massPerParticle = 0.000100

Another variant:

Could not load Ktm32.dll (1815): (null)Error reading histogram line 37: massPerParticle = 0.000100

It appears, based on reviewing the stderr outputs of all of the users that have seen errors, that the application fails when reaching Histogram number 37

Another variant:

Could not load Ktm32.dll (1815): (null)Error reading histogram line 37: massPerParticle = 0.000100

Another variant on the Ktm stuff: Could not load Ktm32.dll (126): The specified module could not be found.

Same for me; all WUs related to plum_slice failed. Error was the histogram line 37 error, along with

The system cannot find the drive specified. (0xf) - exit code 15 (0xf)

Hi Steve,

These "things": ps_plum_slice_EMD_NEW_100K_1341346802_25338, error out, not only at my place, also with wingman.
So you have to study a wee bit more on the code...

Error, error, error... OMG!

It's the 4th of July Holiday in the US....please don't expect any work to be done today.
