Current versions of openssl (e.g. the one in RHEL/CentOS 7) have deprecated older, less secure signature algorithms. This includes md5, which is used by default by sge_ca when running in CSP mode. The result of this is hard-to-diagnose failures when trying to run in CSP mode on such a distribution. Examples include sge_qmaster failing to start on CentOS 7, and a CentOS 7 submit host failing when trying to talk to a CentOS 6 queue master.

Changing the default signature algorithm to sha256 seems to entirely resolve this issue.

As reported in Debian #846770 [1], gridengine fails to build if trying with 64 threads. The problem turns out to be some undeclared prerequisites for the pdc target. The attached patch fixes it for me. The patch is against the v8.1.9 code base.

Thanks and regards Afif

I have installed SGE 8.1.9 from RPM on SUSE 11 SP4.

PROBLEM: Running this command hangs with no output.

sudo /sbin/service sgeexecd.p6444 status

DIAGNOSIS: The cause of this is the sgeexecd script failing to set pidfile and then calling cat which now expects STDIN and so waits indefinitely.

FIX: This is the patch that I used on the script in /etc/init.d. It is a two line change that you can apply to the appropriate source file.

VERIFY: Applying that patch causes the status subcommand to report correctly.
