[petsc-users] Eigenvalue problem in batch

[Timothée Nicolas]

Hi,

Can you be a bit more specific ? You have 1000 different files for A and B
? Like, you have A_0001.bin, A_0002.bin, ... A_1000.bin and B_0001.bin,
B_0002.bin, ... B_1000.bin ?

In that case it's a bash problem and not a petsc problem, you just need to
make a loop on an integer i, use something like

printf -v i2 "%04d" ${i}

so that i2 is written as 0001, 0002, ... 1000, and not as 1, 2, ... , 1000,
concatenate i2 with 'A_' or 'B_' and put that in your launch string. I
expect it should work, you can put variables as petsc arguments.

But what do you mean with multiple cores ? You want to do it in parallel at
the same time ? Then I don't know how to do it.

Best

Timothee
