</div>my question is this:<br></div>because i have about 80 cpus using make -j with value of 80-160 seems right according to information on the web.<br></div>but when using ccache if i get only cache hits, distcc wont run(im using CCACHE_PREFIX=distcc) and i will have 80 processes of ccache running on my local host.<br>
</div>this is much more than the cpus can handle.<br></div>should i use -j as the numbers of cpus on my local host?<br></div>i want to take advantage of all the cpus in the cluster.....<br><br></div>thanks,<br></div><span style="font-family:arial,sans-serif;font-size:13px">tal</span><br>
