Null buffer assertions are suggestive of incorrect programs. Can you share the source of this program? As for the inline vs attached files debate, I think that pastebin is a superior option for large output since it is plain-text readable from any internet-enabled device and doesn't lead to huge messages on the list. But for short messages, inlining is definitely good for email reading on phones. Jeff On Fri, Jun 28, 2013 at 9:46 AM, Danilo <[email protected]> wrote:
In the last topic I read it was asked more that once to zip the files and I did it.. By the way, this is the first error: Assertion failed in file helper_fns.c at line 361: ((((char *) sendbuf + sendtype_true_lb))) != NULL internal ABORT - process 2
Starting from the second execution I get:

Can you just copy paste your error into the email? Most of us will probably not be all that excited about opening up strange tarballs attached to an email. Also, we get these emails on our phones and tablets where unzipping source code isn't as much of an option.

Good afternoon,
I wrote a little application in C to compute 2D fft. This app was firstly executed on a cluster on which it was installed 2007 mpi version (don't remember the package name) and then adapted for a different cluster with mpi 1.4.1 (had to change the scatter/gather because in the previous version I could use the same buffer for both sendbuff and recvbuff). By the way, when executing with 2 processes it works fine. When trying with 4/8/16/32 and so on it gives firstly an assertion error as shown in the file attached, and starting from the second time you try to run it on more than 2 procs it gives error code 139. The error I'm talking about appears just when you run it with "realDim=16384" (it means that you have 16384 rows and 16384x2 columns since it is designed for real/imaginary numbers). I know the code is working since it was all ok on the previous cluster (even with 4-8-16-32 procs) and I can't find out which is the problem now.. Can you help?
As said attached you can find my application as well as the errors appearing and mpi info..
