Hi,
I successfully compiled NWChem-6.0 (stable release) on a Fuji cluster, with 8 Intel core and 24G memory for each node and , however it got problem when I run the QA test for more than 1 cpu
For example, when I try to run autosym in QA/tests with 2 cpu within the same node, I got this memory error message
id=-1 size=33554432
******************* ARMCI INFO ************************
The application attempted to allocate a shared memory segment of 33554432 bytes in size. This might be in addition to segments that were allocated succesfully previously. The current system configuration does not allow enough shared memory to be allocated to the application.
This is most often caused by:
1) system parameter SHMMAX (largest shared memory segment) being too small or
2) insufficient swap space.
Please ask your system administrator to verify if SHMMAX matches the amount of memory needed by your application and the system has sufficient amount of swap space. Most UNIX systems can be easily reconfigured to allow larger shared memory segments,
see http://www.emsl.pnl.gov/docs/global/support.html
In some cases, the problem might be caused by insufficient swap space.

On the other hand, if the job is run across the node, I got another set of error message:

Please let me know what I can do to run the QA test. Thanks
