Subject: [parsec-users] Dedup Memory allocation



Hi,

Following is the definition of MAXBUF (defined in file "dedupdef.h" )

#define MAXBUF (600*1024*1024)     /* 128 MB for buffers */

In bracket it is written 128 MB but figure comes out to be 600MB. Is this a bug or it means something else?

Because of this the malloc function in encoder.c fails. See the following comment:

Enoder.c, Line 652

  u_char * src = (u_char *)malloc(MAXBUF*2);  --> Succeeds
  u_char * left = (u_char *)malloc(MAXBUF);   --> Memory allocation fails here
  u_char * new = (u_char *) malloc(MAXBUF); --> Fails here . Not enough memory to assign.

In 32 bit systems application gets max 2 GB memory. The above three statements exceeds 2 GB limit.

Regards,
Grishma
