Dear Ilona, there will be a new eddy release in the next month or so, and for that we will make sure that we release executables for up to the latest CUDA version (currently 9.1). But Wang Lei is also absolutely correct. You can have multiple installations of the CUDA libraries and development environment at the same time. Looking at my own system I have currently seven versions of CUDA, from 5.5 up to 9.1 all happily co-existing. That means I would be able to run any executable that had been built using any of those versions, and I wouldn’t even need to know which one. It is only the drivers that you need to have the latest, and only one, version of. So, I would suggest you talk to your sysadmin and he can sort you out with installing a selection of older CUDA versions. And when installing new ones (after 9.1), make sure you keep the older ones around.

If I have understood correctly CUDA drivers are kernel drivers and it's not possible to use different versions of CUDA in one computer. ..or at least it's problematic. Sorry to repeat my question again, but is there going to be update for eddy_cuda (for centos7 and cuda9.1, we are updating ours from 9.0). If not, we might be able to translate it ourselves, but would there be possibility to contact someone if some non-trivial problems occur. Thank you in advance!! Best regards Ilona Mun taytyy kaantaa itse FSL'sta versio Centos 7'lle ja CUDA 9.1'selle, mutta se vaatinee myos muidenkin ohjelmistojen kaantamisen, joilla on softariippuvuuksia FSL'n kanssa. Jos sulla on kontakteja FSL'n kehittajiin, niin heita mulle infoa mista voisin kysya lisatietoja mikali kaannosprosessin aikana tulee vastaan joitain ei-triviaaleja ongelmia. ________________________________ Lähettäjä: FSL - FMRIB's Software Library <[log in to unmask]<mailto:[log in to unmask]>> käyttäjän Wang Lei <[log in to unmask]<mailto:[log in to unmask]>> puolesta Lähetetty: perjantai 27. huhtikuuta 2018 18.08 Vastaanottaja: [log in to unmask]<mailto:[log in to unmask]> Aihe: Re: [FSL] eddy_cuda for CUDA version 9.0 Hi, I am not an expert, but I think you can install multiple versons of cuda in your system, as long as your gpu is supportED and you have the authority to install. Just install cuda8 alongside you cuda9 should work. <https://maas.mail.163.com/dashi-web-extend/html/proSignature.html?iconUrl=http://nos.netease.com/mail-online/sm8c960285ff16e19f8a58f45587734068.jpg&name=sungoku2005&uid=sungoku2005%40gmail.com&ftlId=3&items=%5B%22%E9%82%AE%E7%AE%B1%EF%BC%9Asungoku2005%40gmail.com%22%5D> [http://nos.netease.com/mail-online/sm8c960285ff16e19f8a58f45587734068.jpg] sungoku2005 邮箱：[log in to unmask] 签名由 网易邮箱大师<https://mail.163.com/dashi/dlpro.html?from=mail88> 定制 在2018年04月27日 20:09，Ruotsalainen, Ilona<mailto:[log in to unmask]> 写道： Dear FSL Team, I’m analyzing a diffusion images of young subjects and would like to use the new eddy_cuda tool for this data. If I have understood correctly, eddy_cuda works only with CUDA versions 6.5-8.0. In our servers we have CUDA version 9.0 (driver version 390.25) and Centos 7. Is there any way to use eddy_cuda in this environment or are you maybe proving updates for eddy command in near future? I would really appreciate help in this matter. Thank you! Best regards Ilona
