Hello friends,
Recently I was trying to running a program with a large array, to be more specific a unidimensional array of 346840131876 elements. This array is an integer 4 allocatable variable. Besides the large number of elements I just use 0,01% of them (5458868 elements will be used), for this reason, I believed that the program will run. But when the array is allocated the program stops with the message of Insufficient virtual memory. I was running the program on a 64-bit OS with 64GB of RAM and 130GB swap.
My question is, I really need more virtual memory to run this program? or there is another thing to try?
