Multi Threading Support

[Former Member]

Hi ,

The plan is to use Solaris 10 with Sun T5240 server.

The Sun T5240 server uses thread computing (i guess multi-threading) and want to know if it is supported in XI 3.0.

I believe multi-threading and hyper-threading are different technologies.

From what I know, hyper-threading is supported in XI R2.

Any suggestions/insight will be highly appreciated.

Thanks,

N2

Hi;

this threading problem is mostly an OS issue, from an application standpoint, we're using multi-process, multi-threads generically, as long as the OS implements them correctly, we're ok.

So the answer would be yes, but what you want to check is the exact Solaris 10 version and patch level BOXI 3 requires to run correctly.

XI3.1 is fully certified on Solaris 10 platform.

Hi ,

We were testing the T5240's as a new server against the old 1280's and we observed CMS related trasactions( opening a folder, opening a report, browing the folder structure) were slow as compared to 1280 . Also the memory and cpu utilizaition was low . Are you sure T5240's are recommended for BO??

I believe Business Objects is not compiled with multi-threaded support. Hence even though it will work, it will not be able to fully utilize the functionality provided by the multi-threaded OS....

the only version I know of BO that does support multi-threaded OS is the HP-UX 64bit Itanium build. You might see a negligible difference in performance due to the thread computing.

Hi;

no, all BO products are multithreaded, a single proccess will have several threads. (Maybe we don't speak the same language here? and your threads are not mine?), thus if the OS implements a good threading framework, the applications will use it.

For your performance issue, if the server CPU usage is low, are you sure that you don't have a bottle neck because of disk or network IO, like between the CMS and the database it's using? How did you measure performance? is it exactly the same version of the product? etc...

It's not recomended, but fully supported !

If there are problems on this new platform - open a support ticket, so it can be properly investigated.

Thanks. We have a case already a case open. We dont think file system or repository performance play a role in our benchmarking, because we use the same repository server and storage server for benchmarking. The initial observation looking at MP STAT was that a particular thread was loaded with activity where as other threads remain inactive, which should not be the case for a multi thread supported application . Again i am talking of CMT techlonology for solaris. Is there any configuration guildlines for CMP servers. are there any specifc setting with respect to CMP

Were you able to resolve the performance issues with your reports? I am having the same problem with SUN Sparc Enterprise T5220s. I notice heavy disk io but cpu and memory usuage is very low. Any advice or recommendations you could provide would be greatly appreciated.

Penny,

My only suggestion is move out of T5220. These boxes are not good for heavy lifiting applications like BO. The issue with T5220 is that each process is taken by a thread ( 1/64 of a CPU) so the processing power is very low hence poor performance. The T series is only good when you have thousands of light weight process services taken careby threads individually.

I got this confirmation from Business Objects Engineer.
