<div dir="ltr"><div><div><div><div><div><div><div><div>Hi,<br><br></div>I saw this error on CRAN's Mac check logs as well. This seems to be linked with the shared.memory feature when running parallel computations, on Mac only.<br>
I have no Mac to thoroughly check and asked the author of bigmemory to see if he could reproduce the error: he could not when running the example in an R console, but got an error when running the checks.<br></div>So this will need further investigations.<br>
<br></div>Did you reinstall all packages, specially bigmemory, after upgrading to R-3.0.0?<br><br></div>You should still be able to run parallel computations but disabling shared.memory by:<br><br></div>nmf.options(shared.memory=FALSE)<br>
<br></div>If you do not want to remember/type this every time you load NMF, you could simply uninstall the synchronicity package, which you probably do not need otherwise. The shared memory feature will then be disabled for good.<br>
