Hope it's just my computers (but I wouldn't know why), but I've had nearly half of the WUs I got return Error While Computing. The ones that validate only run for a second? Someone please tell me what's going on.

One of my computers successfully completed a couple units which took a couple of hours, as expected. Its stderr.txt output is over 2400 lines long. However, this computer also successfully completed units which took seconds, and their stderr.txt is only about 50 lines. Here is an example:

Yes, we have detected that there is a problem with the files of SteadyState2000 and SteadyState4000. We are working to find what is happening. In local it works properly.

Best,
JEsús.

Hi!

This bug should be fixed using version 1.08 of CRLP2011 applications. Refresh your jobs.

Best regards, Joel.

A lot of wasted hours of CPU time......I'm not sure I should trust this project. My work was listed as error but 2 Linux users completed in a lot shorter time frame. There should be a way to keep the OS's separate. .

There are 4 related units, 2 are In Progress, and 2 also errored. One of the errors was also on version 1.08.

Hi, we will take it into account. That seems to be related to something during the calculus inside the simulation, we will upgrade our app as soon as possible.

http://denis.usj.es/denisathome/result.php?resultid=38323222

Why? all the results lately seem to fail after a couple of days on a Windows PC?

If windows is going to fail, do not provide WU's for them. That is on your end.

I am using 7.6.22 and I have updated my PC OS and Video drivers, so I am current.

I am letting one of the 1.08 tasks continue to see if it completes as expected, but it still says 1 day and 7 hours to go after 8 hours of work. Not at all like the Linux boxes.

Task 38376354 failed on a Linux system, app v1.08:

Compute error for a SteadyState3000 simulation.
Exit status 193 (0xc1) EXIT_SIGNAL
Run time 1 days 0 hours 32 min 10 sec
CPU time 17 hours 57 min
SIGSEGV: segmentation violation


Task 38355439 also failed after 4 days 21 hours albeit on app v1.07.

That system still performs reasonably well; 36 Valid, 3 Invalid and only 2 finished in an error.
