We compared two machines and results are interesting. 'bosh - AMD X2 4200 Windows XP WU-------h--m--s gs_72... 00:19:39 gs_70... 00:19:41 gs_62... 00:05:26 gs_60... 00:05:25 LiborA - AMD A64 2800+ OpenSuse 10.3 64b WU--------h--m--s gs_74 ... 00:13:39 gs_73 ... 00:13:31 gs_72 ... 00:13:43 gs_72 ... 00:13:34 gs_71 ... 00:13:29 gs_62 ... 00:05:26 gs_60 ... 00:05:24 It seems that for non-convolution Work Units the application need a similar time for the WU in the same range. But for Convolution Work Units is linux application a more, more effective. ID: 1168 · Rating: 0 · rate: / Reply Quote

But for Convolution Work Units is linux application a more, more effective. It looks like the windows application isn't being compiled as well as the linux one. The problem behind this might be that the linux is using a 64 bit binary (where i'm pretty sure the windows does not). We're working on getting a 64-bit windows system to compile on which will hopefully improve the times on windows. ID: 1170 · Rating: 1 · rate: / Reply Quote

The problem behind this might be that the linux is using a 64 bit binary (where i'm pretty sure the windows does not). Are you sure? I have downloaded astronomy_1.13_i686-pc-linux-gnu executable, it seems as 32b application? And on download folder isn't x86_64 application available. We're working on getting a 64-bit windows system to compile on which will hopefully improve the times on windows. Its a very good message for all users of 64b Windows OS :-) ID: 1171 · Rating: 0 · rate: / Reply Quote
