Shared memory is used for

Shared memory is used for communication of the science app with the screen saver, for example, so I would not be surprised if that one wouldn't work on the affected systems. Otherwise, the science code can run on regardless of the warning message.

Under Linux, check if your system uses too low a limit for shared memory.

If you execute this as user root

/sbin/sysctl -a | grep shm

it will display the kernel seetings iirc.

On one of my computers, the sysctl command gives me the following :
kernel.shmmax = 33554432
kernel.shmall = 2097152
kernel.shmmni = 4096

Hi! That doesn't seem to

Hi!

That doesn't seem to be exceptionally low. Strange. I understand that message is written by the Boinc library, not the E@H code. So maybe this is something that any BOINC developers here can comment on?

P.S.: I hope this won't stop you from crunching ABP2, the performance of your CUDA enabled PCs is quite impressive.

Bernd already made a short statement here.

I changed my cc_config file

I changed my cc_config file to not show those error messages in the stderr.txt file. It cleaned it up quite a bit.

Why is there even a graphic app for this? It seems counter intuitive. You won't break my heart by disabling graphics on cuda apps. (or any apps)

Edit: My mistake, it cleaned it up because it started working. Now the messages are back.

Beware the dual headed Gentoo with Wine!

Hi !

The reason for this error message was only recently found. A change to prevent this is now submitted into the BOINC source code. I guess a workaround to work with older versions of BOINC will be included in the next version of the app.
