Hi, I've tried versions 2.0.1 and 2.0.3 of NGPT on an SMP Linux Redhat 7.3 system with Kernel 2.4.19 patched with the patch-futex for version 2.0.3. I've followed the installation instructions, to make ngpt initialize at boot time (by the way, the ngptinit file that I had tried to execute //bin/ngptc, which does not exist, I modified it to be /usr/bin/ngptc. Both times I tried NGPT with our application it didn't work well. Our program is cross-platform (Irix, Linux, Windows). On Linux, LinuxThreads do not seem to work very well in terms of scheduling, and some threads end up starving and interactivity is a problem (we are working on an interactive virtual environment, so this is a real problem here). So as I was saying, I decided to give a try to NGPT. So I installed it and recompiled the application after that. But it gets stuck before the main window is spawned, as if all threads were sleeping... Maybe I'm doing something wrong. Or maybe our code does something that is not compatible with NGPT implementation. I have found almost no documentation about NGPT, and nothing that I found explains this. I would appreciate some hint on what could be going wrong. Thank you, -Ignacio Llamas ([email protected])
