I'll go through them in order:

Error loading Lua script 'astronomy_parameters.txt': [string "number_parameters: 4..."]:1: '<name>' expected near '4'
Switching to Parameter File 'astronomy_parameters.txt'
<number_WUs> 4 </number_WUs>
<number_params_per_WU> 26 </number_params_per_WU>


This isn't really an error, it's just the program saying "I didn't find a Lua script, so I'm going to use the parameters file instead". This is actually what we want (the lua script is outdated, and we use parameter files now). This shows up in every workunit.

The warnings that you linked are compiler warnings, so they aren't expected to cause any problems. It just means that the code is written in a way that the compiler doesn't "prefer". This shows up in every workunit.

This one seems to be related to your graphics card, because it doesn't show up in every workunit. Separation does an estimate of how long the WU will take to run before it starts calculations. It does this by looking at how many FLOP/s (floating-point operations per second) your GPU can do. If it's below some expected threshold apparently it comments on that and then warns you that it is actually using another number for the calculation. This could actually be due to the graphics card that you're using, or it could be due to a quirk in how Separation calculates the FLOP/s. Either way, I don't expect it to change anything about the actual calculation.


Thanks Tom for the answer and explanation.
Now I can process the WU safely.

I wanted to bring to Tom's attention, some errors that are in the log stderr_txt of the WU successful both the latest created and those before, here for example:

I just wanted to know if these errors are normal or can cause some problem, even if the processing of the WU is regular?

Thanks Travis, now everything works great!!
He acknowledged the version of the BOINC client, the GPU ATI and downloaded the application and has already ground 9 WU without errors.
Very good and good work.

Why can not I received any WU?
My configuration is as follows:

BOINC client version 6.10.18 for windows_x86_64
Processor: 4 AuthenticAMD AMD Phenom(tm) II X4 955 Processor [AMD64 Family 16 Model 4 Stepping 2]
Processor: 512.00 KB cache
Processor features: fpu tsc pae nx sse sse2 pni
OS: Microsoft Windows 7: Ultimate x64 Edition, (06.01.7100.00)

ATI GPU 0: ATI Radeon HD 4700/4800 (RV740/RV770) (CAL version 1.4.317, 1024MB, 1360 GFLOPS peak)
Catalist 9.6

Because the details of my host, but I see I see a problem of all, the coprocessor is not ATI and the version of the BOINC client?
While in the projects, like Seti, Aqua and Collatz there are regular.
Thanks in advance x responses.

I state that I have problems updating your profile, but I must make a note on the home page of the site with regard to the news, it is true that we are only a few days in the new year, but we are in 2010 and 2009. :-)
