COMPUTE vs. DISPLAY

[magnum]

Is it just me or did AMD drop the COMPUTE environment variable overriding DISPLAY in 13.12? I found it very handy for ssh -X sessions but it doesn't work anymore.

Fwiw it could be worked around within oclHashcat, eg. like this:

Code:

char *env;

// Prefer COMPUTE over DISPLAY and lacking both, assume :0
env = getenv("COMPUTE");
if (env && *env)
    setenv("DISPLAY", env, 1);
else {
    env = getenv("DISPLAY");
    if (!env || !*env)
        setenv("DISPLAY", ":0", 1);
}

I was going to add a request on trac but I thought I'd ask for others opinions/insights first.

Compute is just an override. It doesn't have to exist by default.

The problem is it doesn't seem to be honored anymore, using 13.12. If I have COMPUTE=:0 and DISPLAY=localhost:10.0 (from ssh -X) it will use the latter and fail. I think COMPUTE worked fine up to and including last beta before the release driver. My suggested workaround more or less restores the functionality.
