Dear All, I tried to perform a TDDFT calculation on a molecule of 124 atoms with 488 electrons at b3lyp/6-31g* level (1158 AOs). The task has been running on a workstation equipped with 4-cpu/48-cores and 128 GB of RAM (and also 5 HDDs of 2 TB each). This is the input deck I used:

After the completion of the scf cycles, as soon as the the code enters the TDDFT procedure, the following error occurs:
ARMCI INFO
The application attempted to allocate a shared memory segment of 5045551104 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.

and ARMCI_DEFAULT_SHMMAX=4096 (I also tried with ARMCI_DEFAULT_SHMMAX=8192 but nothing changes).
If someone can put me in the right direction, I really appreciate.
Thanks a lot,
Davide

I have the same problem, so I thought would post my problem here instead of creating a new post.
I'm trying to do a TDDFT (B3LYP/6-31G**) calculation on a relatively large molecule (134) but I keep getting the error shown above. I'm running the job on 24 nodes each with 8 cores and 12 GB memory. Here is my input file:

Davide,
The code clearly tries to allocate more then 8 Gbyte of shared memory, and in your NWChem input you ask for a maximum up to 24x1Gbyte of shared memory to be available.
One thing you can try is to see if the calculation runs with a maximum of 8 cores per node, which would force the calculation to stay within the shemmax limit you have set.
Alternatively, you could increase the kernel.shmmax to 24 Gbyte. This will probably lead to the code generating multiple shared memory segments of the size ARMCI_DEFAULT_SHMMAX. The development version is addressing this issue, and another issue I will come back to with Mef362.
Mef262,
What are your kernel.shmmax and ARMCI_DEFAULT_SHMMAX settings? In your case, you should have the kernel.shmmax set to over 4 Gbyte and have ARMCI_DEFAULT_SHMMAX=4096.
Both,
We have seen some large memory usage in the TDDFT in NWChem 6.1 versions. We have addressed this in the TDDFT module and the global array parallel infrastructure of the development version that is being prepared for release as we speak.

I got the same error as Davide on a system with the following settings
16 cores with 32 GB memory per node
kernel.shmmax = 1073741824
ARMCI_DEFAULT_SHMMAX=8092
I tried even using 100 nodes.
I tried on a different cluster with the following settings:
8 cores with 12 GB memory per node
kernel.shmmax = 68719476736
ARMCI_DEFAULT_SHMMAX=8092
and get the following error:

When do you think the new version will be available?
Also, I'm willing to be a Beta tester if needed; mainly because I hear the new version should work on Qlogic IB.

Thank you very much Bert for your kind reply.
I will try both your suggestions (running up on just only 8 cores as well as increasing the kernel.shmmax to 24 Gbyte or more).
If nothing changes in a positive way, I will wait for the new release which adresses this issue.
All the best,
Davide
Quote:Bert Apr 17th 2:47 pmDavide,
The code clearly tries to allocate more then 8 Gbyte of shared memory, and in your NWChem input you ask for a maximum up to 24x1Gbyte of shared memory to be available.
One thing you can try is to see if the calculation runs with a maximum of 8 cores per node, which would force the calculation to stay within the shemmax limit you have set.
Alternatively, you could increase the kernel.shmmax to 24 Gbyte. This will probably lead to the code generating multiple shared memory segments of the size ARMCI_DEFAULT_SHMMAX. The development version is addressing this issue, and another issue I will come back to with Mef362.
Mef262,
What are your kernel.shmmax and ARMCI_DEFAULT_SHMMAX settings? In your case, you should have the kernel.shmmax set to over 4 Gbyte and have ARMCI_DEFAULT_SHMMAX=4096.
Both,
We have seen some large memory usage in the TDDFT in NWChem 6.1 versions. We have addressed this in the TDDFT module and the global array parallel infrastructure of the development version that is being prepared for release as we speak.

Dear All, I was experimenting a little bit with different settings for kernel.shmmax
and ARMCI_DEFAULT_SHMMAX values. I used the same input deck reported in the 1st post
but the simulation was developped just using only 8 cores (as suggested by Bert) for all the tests.
Test 1): kernel.shmmax = 8589934592 (8192 MB), ARMCI_DEFAULT_SHMMAX=8192
The error obtained (after the dft-scf procedure) is:
- ARMCI INFO ************************
The application attempted to allocate a shared memory segment of 4294967296 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.

The error on the last message reflects that you are running out of global memory. You could now try to increase the number of processors (maybe double) and see.

Dear Bert, I tried to use 16 cores (instead of 8) but the job ended just after the scf-dft cycles with the "first type" of error:
- ARMCI INFO ************************
The application attempted to allocate a shared memory segment of 3157917696 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.

Thank you very much for your support.
