Hi All, I am trying to solve a sparse system of equations using PARDISO OOC but somehow I ran into error -2, which according to the help manual, is due to memory shortage. I also obtained the following error after reordering:
*** Error in PARDISO (Insufficient_memory) error_num -1100 ***Error in PARDISO memory allocation: FACT_L&U, size to allocate: 1712271416 bytes total memory wanted here: 1677421kbyte symbolic (max): 321026 symbolic (permanent): 5280 real(including 1 factor): 1672141
My workstation has a 24GB RAM. Could someone please help me.
Often the problem is caused by that the application is 32 bit, which is limited by 2G memory space. If this is not the problem for you, could you please provide some more information on: 1) MKL version. 2)linkage command line 3) the processors you are testing?
If you even have one test code, that will help a lot to identify the problem.
