Hi,
I tried to use the hello example for cray from Impulse C to run on Cray XD1, it seems that it is not working.
this is the command line
"
Impulse C is Copyright 2003-2005 Impulse Accelerated Technologies, Inc.
Software sending value: ffffffff00000000
"
then it stopped without giving any result.

I changed this hello example to add one done signal in order to run on SGI
this time
the result is"
Impulse C is Copyright 2003-2005 Impulse Accelerated Technologies, Inc.
Software sending value: ffffffff00000000
FPGA hardware returns: 0000000000000000
Software sending value: 5555555577777777
FPGA hardware returns: 0000000000000000
Software sending value: 1234567887654321
FPGA hardware returns: 0000000000000000


Application complete. Press the Enter key to continue.

"
obviously, the FPGA returned all zero values. Originally, the hello example is to swap the upper 32 bits with the lower 32bits.
May I know what the problem is?
Thanks

BTW I am using the latest Co-developer version 3.2

Hi Tony,

Could you share your code with us by posting it here or emailing it to support@impulsec.com? We can try to reproduce the issue.

Are you using RASC 2.11?

Ralph

hi, please see my code for RASC RC100, i am using RASC 2.2, previous I forgot to add the co_interate and deselect the co_port option when generating the HDL, after fixing this, still, when processing, the SGI machine doesn't have any response. I am wondering if u could reproduce this code on the machine ASAP and give me any feedback on what is wrong with my code. Because this is an only helloworld program. May I know whether it is possible for you to provide me with a Helloworld example which could be able to run on SGI machine since there is only one helloworld example for CRAY XD1.
Thank u so much.

The following is the code I run on SGI

Hi Tony,

The PSP for the SGI RC100 does not support RASC 2.2 at this time, only 2.11. Is downgrading to the earlier version a possibility for you?

I don't think it's possible for us to do it. However, I run the MersenneTwister32 example for SGI, it did work. Do u know any reason or solution for it? Thanks

Hi, can u send me or upload a helloworld example for SGI with one input stream and one output stream please, thanks
