1) Message boards : Questions and problems : Client abort jobs while copying large files (Message 21215) Posted 13 Nov 2008 by Andres Post: Hi, I am running a custom project in my boinc client and the following problem happens with the created works. I create several workunites which share the same input, a couple of large (80~ MB) files. When my client get the jobs, it try to execute 2 jobs (since the PC is dual core), and when it start to copy the input files to the temporal folder, the client freezes, and then one of the jobs get cancelled (it shows a calculation error). I tried to stop both jobs, launch the first and wait until it copy the files. Then, while the first is running, I launch the second, and (again) while it is copying the input files, que client freezes and then the first job throws a calculation error, while the second keeps running fine. Any idea of why is this happening? Is there any workaround or the only solution is reference the input files with soft links instead of copy_file? Thank you.

2) Message boards : Server programs : Host groups (Message 20946) Posted 24 Oct 2008 by Andres Post: It is possible to make 'host groups' to force the server to send specific jobs only to those hosts? The situation is like this: we have task A which requires the program X to be installed on the target host. However, since it is impossible to install it on-the-fly we need to install it beforehand; also we have task B, C ... which does'nt require any specific software. Is there a way to create a group of hosts e.g. 'host with program X installed' to make the server send task A only to those, while sending tasks B, C... to everybody? Thanks.
