AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello

How do i get the libraries for 3dDeconvolve to not overload malloc? We've made the begining changes to MPI-ize 3dDeconvolve and tried to run a test but got the following error:
[1] Malloc hook test failed: the malloc provided by MPICH-GM is not used, it may have been overloaded by a malloc provided by another library.

This is a mpi error, but it is because some library is overloading malloc. After a couple hours of grepping the source files, my partner and i found several places where #define's redifine what gets called when malloc() is called. We added #define DONT_USE_MCW_MALLOC in mcw_malloc.h, but no luck. We added the command line arg '-nomall' but still no luck. I even commented out the lines in 3dDeconvolve where enable_mcw_malloc() is called, but still no luck.

We've asked the admin of the supercomputer we are using to see if they can install a version of mpich that doesn't care if malloc is overloaded, but we don't know at the moment if they can do that. We hope that some of the developers who wrote this can help us out...

Thanks! Happy ThanksGiving!!!
