Large IFC memory requirements (cf CVF)

[tonyjay68]

My 100 project CVF workspace (mainly mixed fortran/C++) projects takes up less than100 MB of virtual memory

When I import it to IFC and start to extract the fortran projects (one by one, very laborious) the virtual memory requirements grow.

Having extracted half the project and compiled them the studio iscurrently using 500MB virtual memory.

As my intel porting machine only has half aGIG, the stdio has ground to a halt (to compile one file is taking a long time). The only work around is to delete the fortran projects from the workspace.

On my real machine I have 1GB of memory and regualry run 3 studios at the same time.

Has anyone else noticed this.

Submitting this as a bug to Intel is going to be fun, how does one reproduce it without sending 100 projects with 1000's of files.

ps right click on an include file in IFC and look for the "open document" menu entry - Oh it ihas not been implemented, go search your include path.

I tried an experiment on a multi-project workspace I had. Here's what I came up with:

CVF - 15604K

VS.NET (after coverting to the VS.NET format, but before extracting the Fortran projects) - 21000K

1 project converted - 32148K

2 projects converted - 33076K

3 projects converted - 34044K

So it looks as if there's an additional 1MB per project (or a bit less). Extrapolating from there, if I had a 100-project solution, that would be about 132MB - a lot, but not unmanageable.

As I suggested earlier, if you are seeing something different, the only way to get it looked at is to submit a sample CVF workspace to Intel Support.

Tony,

I too have seen this behavior and turned in an issue on it ( Issue #231637 ).

Briefly, I am responsible for CVF application that is comprised of 94 projects all within the same workspace. 41 are programs, 53 are libraries that the projects link against.

Have had it this way in CVF since November 2000.

I started evaluation of IVF 8 and after converting approx. 1/3 of the .vcproj to .vfproj, I received a low virtual memory warning. First time it has ever happened. At the time I had a single 655 MB pagefile. Installed a secondary pagefile of 655 MB and was finally able to get thru the conversion.

Takes approx. 3 min just to bring up the new solution. Can't do much else either while it is bringing it up. Takes approx. 3 min 30 sec just to close it.

My VM Size according to Task Manager after bringing up the solution is > 1 GB.

Please submit an issue. The more that verify this as a problem, the more likely we will see a resolution.

Steve:

Impractical to expect someone to supply a solution to recreate this. Mine is > 120MB zipped ( Premier support limits uploaded files to 10MB ). Not to mention the sensitive nature of the source ( an application that is sold and/or leased ) that the people I work for would not want to get loose.

Thanks for the added info. I have sent e-mail to the project converter engineer to get his comments.

I'm glad to see I'm not the only one to use the studio in this way.

Some times I think i've got the wrong end of the stick on how to use the studio for multi-program / multi-project software suites.

I'm not sure how many people have upgraded CVF to Intel, but there can not be many serious users as there are many conversion bugs still kicking around with projects and dependancies (all the other ones are reported)

Steve.

Extracting fortran fromONE of my projects increases the virtual memory by 80 MB.

Perhaps something is very wrong somewhere.

I have sent a copy to premier support (look under 233327 if you want to see the dsp)

Thanks - the engineers tell me that if you just send the dsw and dsp files, either omitting the sources or supplying empty source files, they would be able to investigate. Thanks for sending the dsp, Tony.

The premier support engineer could not reproduce the problem

Can anyone confirm that the attached dsp increases the memory requirement (virtual and normal !) by 80MB when converted to a fortran project.

Perhaps my configuration is causing the problems ?

Tony

[tonyjay68]

Steve,

Can you quickly check the project I have attached. I need to see if the Virtual memory problem is to do with my machine (premier have gone quiet on it)

Tony

[Steven_L_Intel1]

Sorry, meant to reply earlier. I can reproduce the problem with your .dsp. It has been escalated to engineering.

Thanks
