It is very likely a bug in your code. Without a toy program to reproduce your error, it is hard for us to help. Also, could you use newer MPICH releases like MPICH 3.1.1? --Junchao Zhang On Wed, Jul 2, 2014 at 3:02 PM, mark <[email protected]> wrote:
Hello. In a program i am writing, i have an array which size is equal to the number of nodes in my cluster. I made this array to keep an eye of the objects that each node has in his control and when i use it with the actual ranks of the nodes as positions ( *array[node_rank]=objects;*) it returns me an error and stops the execution:
*rank 0 in job 10 Calliope_49755 caused collective abort of all ranks* * exit status of rank 0: killed by signal 11 *
However, i had freely used the variable *id* or *node_rank* to point out a specific action for a specific node since now and never had problems.
If instead of using the ranks node as a pointer for the array, i use an integer i.e. 5, the program runs fine, but even now, 1 out of 7 executions, it returns me an error and stops. The action i am calling that keeps returning me the error is a simple abstraction (*array[id]--;*).
Any ideas?
PS. The array is 1d and is created by allocating memory, like this : *int *array = malloc(processes * sizeof(int));*
