parallel_studio_xe_2011_sp1_update2

Hello Everyone,

I have installed the Parallel Studio (parallel_studio_xe_2011_sp1_update2_intel64_setup.exe) on my Linux box. The compilation seems 2-3 time  slower compared to intel 11.1 compiler. I  tried to perform the test on  "Hello World" Program and see the same behaviour.  

Thanks.

Please provide more technical details. Thanks in advance.

PS:
I still use IPS 2011 SP1 Update 3 ( our versions are very close / however on Windows XP ) and I didn't have any performance related issues with compilation on a real project ( not a small test-case ).

Hi Sergey,

I have installed the IPS SP3 Update3 yesterday and with that compilation is extremely fast but I am concern about the  IPS SP3 Update2, actually all our builds are being created  with the IPS SP3 Update2. Can you please confirm if there is any compilation time issue with Update2

These are the details

>>...Can you please confirm if there is any compilation time issue with Update2...

Sorry, I can't confirm it and please take a look at a list of fixes:

Web-topic: List of fixes for Intel(R) Composer XE 2011 compilers ( no further updates ):
Web-link: http://software.intel.com/en-us/articles/intel-composer-xe-2011-compiler...

I think you need to move on a more stable / latest update.

Hello Santosh,

the only reason I know of that could have this effect is the license check-out done with every compiler invocation. Which license model are you using (floating or single)? Floating licenses require connection to a license manager. This is usually done via network and thus slower than installing single license files on the local system.

I'm also confused about "parallel_studio_xe_2011_sp1_update2_intel64_setup.exe". Didn't you mean "parallel_studio_xe_2011_sp1_update2_intel64.tgz"?

Best regards,

Hi Georg,

That was just by mistake, I mean to say ""parallel_studio_xe_2011_sp1_update2_intel64.tgz". actually I am using floatinng license. I have installed    "parallel_studio_xe_2011_sp1_update3_intel64.tgz and poining it the same same license server and it is compiling very fast (2 -3 time faster). I  am fine to move to update3 but before I  just want confirmation if there was real issue with update2. 

Thanks.

Santosh

Hello,

the differences between Intel(R) Parallel Studio XE 2011 Update 2 & Update 3 are ranging from Update 9 to Update 11 for the enclosed Intel(R) Composer package (which contains the compiler). According to the fix list we made some corrections in this area but non was explicitly described to be related to performance. Nevertheless, not all improvements are documented as tickets because engineers also fix problems they observe themselves.
In addition, those updates only get smaller changes and improvements observed should last for the remaining updates as well.

Unfortunately, I cannot name you exactly who fixed this and when (possible but efforts to investigate are quite high), but improvements like that are to be expected.

While you are moving to a newer version already: I'd recommend to use the latest Intel(R) Composer XE 2011 Update 13 version which you have to update/install manually after installing Intel(R) Parallel Studio XE 2011 Update 3. The latter only contains Intel(R) Composer XE 2011 Update 11.

Best regards,

Georg Zitzlsberger
