Well, it depends, what you mean about memory management.
Linux kernels are very flexible and have many options about memory management, so it depends on your kernel config.
But yes many people say thta *BSD OOSS have better memory management, better TCP stack and better stability, but all the BSDs lack in terms of features, linux have much features than BSD, and in my opinion this is the typical flameware discussion.
Look at MAC OSX, it is a BSD, and i dont think that it has better network layer, memory manegement and features than linux, instead i think the linux is better by far.
Only in very specialized distributions like OpenBSD or NetBSD, that are very optimized and focused in server applications i think that you can found differencies in memory, security, etc .. but this OOSS have few features than Linux.

Thanks Jeff for your answers, very instructive.
I will try with the performance monitor to know more about the cooking process.
But what do you think about the two problems i have:
-First: in my scene i have a VEX Surface Shader with a custom shader i have developed (for instance /vex/test1), i have created a Shop from this, this new shop is for example /shop/test1. The shop has three parameters, i set up this parameters and save and close the scene. Then i reopen the scene and i get two strange behaviours, Sometimes i get an error that says the the parameters in /shop/test1 couldn't be recognized and the if i go to the shop the parameter pane appears blank, without any of the parameters of the shader, i have to use File->Refresh Operator Type Libraries to get the parameters, that obvoiusly are initialized with the default values. Other times i don't get any error but the parameters of /shop/test1 appears with the default values, no with the values i set the last time.
-Second: in some OBJ operators i have created from a custom HDA i get similar errors that the previous one, normaly i have to force a recook of the HDA instances in order that all the parameters recognize their values.
Maybe i have errors with the HDA and their instances, but the first case is quite simple, and i can't understand why it is failing.
Why if i recook all the parameters are right and not when i simply open the scene.
Thanks
your networks are poorly constructed or you don't quite yet understand how Houdini evaluates it's networks.Maybe i have missed something about nodes cooking.

Hi SESI, it is only a little issue in the operator menu popup.
I think that the Edge Blue operator must be in the Effects section too.

More details about the problem.
I have debuged some operator definitions that i have, and it seems that the scene is more stable now.
But sometimes the problems comes because some custom operator instances, instances from a HDA, when the scene is just opened seems to not have their paramers corrects, forcing a reccok of all the scene, for example moving from frame 1 to 3. and he reseting the animation, and then the parameters works fine. But i have to force this recook.
Some clues.
Other ways to force a recook, from hscript?

Thansk andrew.
Only one other thing that will close the houdini complete integration with all the renderman render family.
Could be possible to add an option to choose the application to use for the IPR, at the moment there are two application in the renderman world for quick render previews, irma from pixar and bake air from sitex (AIR), it could be great to have support for both or an open infrastructure that allows to integrate any similar software easily in the software.
Thanks

Yes i know ondrej.
Let me a few days to finish the project i am involved in, and i will try to prepare an example for you.

I am agree with both of you.
It would be very handy to have control over the compilers for vex and rsl.
Even more, the perfect would be to have a global setting in Main Settigns and a local setting for every network so much in the output VOP as in the surface shader VOP.
Please SESI an RFE for this.

I mean that the dialog for the shaders that aren't well recognized appears complitely blank, no labels and no fields.
The parameters are missing from the dialog.

I have cerated otl for every shader i have in my VOP networks.
Deleted the shader contained in some subnetworks that caused the errors.
Crated new shaders from my otl definitions. not from the VOPs and now all seems to work right.
Posibily a operator names errors that caused Houdini to not get the correct definition ?

Hi all.
I am getting some mantra error like this:
mantra: Singular matrix detected “/obj/Window3/WindowSmoke”
…
And so on.
Anybody knows why is it happening?
Th object only contains a particle system without any geo copied or instanced to the particles.
I am not using motion blur.
Houdini 8.0.398 windows
Thanks

I have checked the last definitions, and all seems to be right.
The problem is that whenever i reopen the file some shaders parameters are not right recognized and their parameters field appears blank.
All of these shaders came from several VOP networks i have in the scene.
So whenever i open the scene the shaders from my VOP network are not correctly loaded and their parameters are not recognized.
I have to refresh all the operators and setuop again all the parameters.

Hi list, i want to generate deep shadows from a mantra ROP.
I know i can generate Depth Shadow Maps using the -Z or -z parameters for the mantra command, but what about Deep Shadows, is possible to render them from a Mantra ROP?
Thanks

The crash when interrupting should now be fixed in version 8.0.398 and up. It was a bug in the source POP when Accurate Births was turned on.Thanks SESI, i have tried with the 398 ad the bug seems to be solved
The problems with the parameters stills, i have to refresh all my operators explicitely every time i open the scene.
Is this my error or is a problem in houdini?
If is my error, how can i solve it?
Thanks

As a wild stab in the dark, do you have an AttribCreate SOP in your network?Yes, i have three AttribCreate SOP.
As a side issue sometimes when i am cooking my effect i gater these messages in the Houdini console:
UI_Queue::queueEvent event queue full. Events being dropped.
UI_Queue::queueEvent 3147 events dropped.
And so on …
When the application crashes the Houdini console says that it is due to a Segmentation Fault, so i am almost sure that is a memory (pointer) problem.
Another strange thing is that when i open the fail i get some errors about not recognized parameters in some of my shaders, and if i see these sahders parameters they are missing, if i press File->Refresh Operator Type Libraries the errors are solved. This is normal?
I have uploaded the scene file with the data needed to :

Hi SESI, i'm unable to render this IFD with mantra, if i launch the render for
houdini i get the typical crash window message.
If i run mantra from the command line nothing is rendered.
Here is the IFD file:

Any clues …..

Hi all.
I´m using the last production release and when i stop cooking using the ESC key houdini crashes.
I'm using Houdini 8.0.383 on Windows.
any other people with the same problem?
